Description

  The present invention relates to a cost accumulation system, and more particularly to a totalization system suitable for use in cost management of construction of buildings and exteriors.

2. Description of the Related Art Conventionally, there is known an integration system that obtains a highly accurate estimate when performing construction such as a building or exterior (for example, Patent Document 1).
In Patent Document 1, a terminal computer, a center computer, and a supplier computer arranged at each sales office are connected via a communication unit so as to be able to communicate with each other. The center computer collects information necessary for designing the building according to the customer's request.
Then, when making an estimate, when the customer selects a building and enters it into the center computer, the materials and quantity required for building the building are obtained. Based on the standard unit price of the materials that have been entered in advance, You can ask for an estimate. It is also described that each supplier computer can place an order based on an estimate sheet.
In addition, a technique for obtaining a construction cost after completion of construction is also known (see, for example, Patent Document 2).

JP 2005-4528 A JP-A-2005-32186

By the way, a construction management company that has contracted the exterior construction of a building purchases necessary materials from a wholesaler (ordering party).
In the case of exterior construction, etc., there are various types of materials, and purchases are often made from a plurality of wholesalers for each type of material. In addition, the unit price of the material varies with the market price, and the quantity often varies depending on the situation of the construction site.

Normally, exterior work associated with home construction is performed at the point of delivery of the house to the client, and the construction cost (cost) is calculated by “closing the house”.
The flow from the contractor to the closing of the mansion when purchasing products with variable factors such as unit price and quantity is as follows.
(1) The orderer places an order with the contractor.
(2) The contractor submits an estimate for the order to the orderer.
(3) The orderer accepts the estimate and requests delivery to the contractor.
(4) The contractor delivers the material to the place designated by the orderer.
(5) The contractor charges the orderer.
After the above processing is performed in parallel for each contractor,
(6) The orderer sums up the invoice amount of each invoice from each contractor and sets it as “closing the house”.

For accounting purposes, it is preferable to be billed immediately after delivery, but it is customary for each contractor to issue invoices in a lump after the “monthly closing” for each month. Therefore, when it was long from delivery to billing, a delay of one month or more may occur.
Therefore, the bill of (5) above may be sent after performing the above (6) “Shutting down the mansion”. In such a case, the amount of the bill sent late is not integrated into the integrated value obtained in (6) above, and the cost of the residence cannot be integrated correctly.
Furthermore, when the construction content has changed after the construction has started and additional materials are required, the number of invoices has increased and the above problem has become more complicated.
In addition, the orderer has to transfer the contents of the received invoice to the company's own system for accumulating, which is troublesome. In addition, there was a risk that a transcription error occurred during the transcription, and an error occurred in the integrated value.

  An object of the present invention is to solve the above-described problems, and an object of the present invention is to provide an integration system that can reduce the input effort and can accurately accumulate the cost of construction work.

The cost management unit stores the cost data in association with each house as the construction unit,
2. The accumulation system according to claim 1, wherein the cost accumulation unit accumulates and displays response cost data including a delivery quantity and a delivery price stored in the storage unit in association with the residence.

The invention according to claim 3 is the integration system according to claim 2,
The first input / output device converts the cost data described in a construction estimate prepared outside the system for a contract with a customer into the entry column of the order details screen as the order cost data. The integrating system is characterized by having a conversion unit for input.

  According to a fourth aspect of the present invention, in the integrating system according to the second or third aspect, the controller of the first input / output device is configured such that the orderer is filled in by the second input / output device. In response to the determination that the response cost data is appropriate, an accumulating system is provided that performs an approval process for informing the second input / output device that delivery is permitted.

Further, the invention according to claim 5 is the integrating system according to any one of claims 2 to 4,
The first entry control unit displays a process management screen having a contractor and construction period entry field, and stores the construction contractor and the construction period entered in the process management screen in the storage unit. It was set as the integration system characterized by performing.

In the present invention, the first input / output device is installed on the orderer side, while the second input / output device is installed on the contractor side.
Then, an order is placed with the contractor (second input / output device) using the first input / output device. Further, when the contractor knows that the order has been received by the second input / output device, the response cost data including the amount determined in response to the order and the scheduled delivery date is obtained using the second input / output device. , Fill in the entry field to fill in when the expected delivery date is confirmed.
Thereafter, when the orderer integrates the cost data, the response cost data input by the contractor and stored in the storage unit is integrated using the cost integration unit of the first input / output device.
As described above, according to the present invention, the response cost data used for integration is the response cost data input by the contractor at the time when the delivery date is confirmed. And there are no transcription errors. In addition, response cost data can be entered by the contractor when the delivery date is confirmed, so that accurate values that are not predicted values can be entered before the invoice is issued. Thus, compared with the case where the orderer inputs after the invoice is received, the possibility of omission of accounting at the time of integration is reduced, and accurate integration is possible accordingly.

In the invention described in claim 2, in the exterior construction of a residential building, there are various types of materials, and there is a high possibility that the time of delivery and the time of issuing an invoice differ depending on the type of materials.
On the other hand, in the invention according to claim 2, the second input / output device is installed in the wholesaler as the contractor so that the wholesaler inputs accurate response cost data of the material.
Therefore, the above-described reduction in inputting time on the ordering side, and the accurate effect of accumulating costs without any transfer mistakes or omissions become more prominent.

Further, in the invention according to claim 3, the cost data of the construction estimate prepared outside the system for the contract with the customer before the construction is performed is converted by the conversion unit, and is entered in the entry column of the order specification screen.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

(Embodiment 1)
As shown in FIG. 1, the integrating system according to the first embodiment includes a first input / output device 21 installed in an outside construction department of an orderer Or, that is, a house building sales company, and a contractor TY, that is, outside construction. It is provided with a second input / output device 22 installed in a wholesale store of materials to be used, a server 30 for storing cost data relating to the material, and a communication line 10 connecting them, The server 30 can be accessed.

  In the first embodiment, so-called personal computers are used for the input / output devices 21 and 22, respectively, and input units 211 and 221 for inputting signals from input means such as keyboards 21k and 22k, and visual inputs, respectively. Monitors 21m and 22m for various outputs, output units 212 and 222 for transmitting and receiving to / from the audio device for outputting sound and the communication line 10, and processing based on inputs from the input units 211 and 221 for output unit Are provided with control units 213 and 223 for outputting from the control unit. The control unit 213 of the first input / output device 21 includes an entry control unit 213a, a conversion unit 213b, and a cost integration unit 213c, which will be described later. On the other hand, the control unit 213 of the second input / output device 22 includes an entry control unit 223a described later.

  In the following, the integration system according to the first embodiment will be described by taking as an example the case where it is used for integrating material costs in a department in charge of exterior construction of a house in a housing construction sales company as an orderer Or. .

FIG. 2 explains the relationship between the orderer Or and the contractor TY based on a conceptual diagram showing the ordering situation of the external construction.
In the external construction department as the orderer Or, when performing external construction on a plurality of customers (houses) CU1, CU2, CU3, CU4 shown in FIG. The construction contractors M1, M2 and M3 are ordered, and materials used for the construction are ordered from one or more wholesalers as the contractor TY. Further, the wholesaler as the contractor TY orders materials from material dealers De1, De2, De3 such as manufacturers. Each material dealer De1, De2, De3 delivers the product directly to the construction site of the customers CU1, CU2, CU3, CU4 or via the contractor TY.

  The orderer Or obtains the cost (accumulated value of cost data) when obtaining the profit of the external construction. This cost includes a construction cost to be paid to the contractor and a material cost to be paid to the contractor TY, and the integrating system of the first embodiment is used to obtain the material cost among these costs.

  Returning to FIG. 1, the server 30 is a database for managing cost data, and cost data related to material costs (material type (name), quantity, price, delivery date, etc.) is stored in association with each house. A management unit 31 is provided. That is, the first input / output device 21 and the second input / output device 22 have the control units 213 and 223, respectively, the entry control unit 213a corresponding to the first entry control unit and the entry control corresponding to the second entry control unit. A portion 223a is provided.

  That is, when the cost control unit 31 is accessed by the control units 213 and 223 via the communication line 10, the entry control units 213a and 223a present input screens on the monitors 21m and 22m, respectively. When the cost data is input in the entry field of this screen, the cost data is stored in the storage unit 31a of the cost management unit 31. Note that such communication and display on the monitors 21m and 22m use a commonly used browser.

As the above input screen, a process management screen WS shown in FIG. 3 and an order detail screen DT shown in FIG. 4 are set.
The process management screen WS is used for managing the schedule of the external construction and associating material-related data with the construction schedule.
In this process management screen WS, as shown in FIG. 3, a contractor column Mr in which the contractors M1, M2, and M3 are entered for each row, and customers CU1, CU2, CU3, and CU4 (each corresponding to a residence). ) To fill in the customer column CUr, the process column Kr to fill in the construction contents for each row, the planned column PLr to fill in the construction schedule for each row, and the sales persons T1, T2, T3 for each row. A person-in-charge column Tr and a calendar column CLr in which the work period and the address of the residence are displayed along a calendar extending in the horizontal axis are provided.

  As shown in FIG. 4, the order specification screen DT corresponds to the material name column SZr in which the names of the materials SZ1, SZ2,... SZ7 to be ordered for each row are entered, and the names entered in these material name columns SZr. A specification column SYr for entering the model number and manufacturer name of the material for each row, a quantity column AMr for entering the quantity of the material to be ordered corresponding to the name entered in the material name column SZr, and the unit price of the material are entered. A unit price column UPr, an amount column MOr for displaying the amount obtained by multiplying the entered quantity and unit price, an order date column Odr for entering the order date, and a delivery date column DLr for entering and displaying the delivery date are provided. ing.

  Note that the first input / output device 21 installed in the orderer Or can display both the process management screen WS and the order detail screen DT based on the setting of the expense management unit 31 and the both screens WS. , DT is set so that ordering cost data can be entered in each entry field. On the other hand, the second input / output device 22 installed in the contractor (wholesaler) TY cannot access the process management screen WS stored in the expense management unit 31 and can display only the order detail screen DT. In addition, in this order detail screen DT, response cost data can be input in each column of the quantity column AMr, the unit price column UPr, the amount column MOr, and the delivery date column DLr.

  Therefore, in the first embodiment, in each column AMr, UPr, MOr, Odr, etc., the data entered by the orderer Or by the first input / output device 21 corresponds to the ordering cost data, and the contractor TY receives the second input / output. The response cost data is overwritten by the device 22. That is, the value first entered by the first input / output device 21 is an estimated value or a desired value, and the value entered by the second input / output device 22 is the actual price. In the delivery date column DLr, the date entered by the first input / output device 21 is the desired delivery date, and the date entered by the second input / output device 22 is the scheduled delivery date.

Next, based on the flowcharts shown in FIGS. 5 to 9, the flow of cost data integration processing and the flow of display and input work by the input devices 21 and 22 will be described.
FIG. 5 shows the overall flow of work from the occurrence of external construction to the storage of cost data necessary for integrating material cost data corresponding to a residence as a construction unit.

The overall work flow will be described with reference to FIG. 5. The external work is generated along with the construction of each house.
When carrying out this external construction work, first, the sales representative T of the housing construction sales company makes a meeting with the customer CU (if the customer is not specified as one of CU1 to CU4, the customer is indicated as CU). Then, the construction content is determined according to the request of the customer CU (step S1), and an estimate is created (step S2). This estimate may be created using the first input / output device 21, but in the first embodiment, it is assumed that the estimate is created by the third input / output device 23 that is not included in this integration system. The third input / output device 23 includes a monitor 23m and a keyboard 23k.

  And when the internal approval of this estimate is obtained in a sales department etc. (step S3), after that, a contract is exchanged with the customer CU (step S4). When this contract is established, the orderer Or starts the construction work to the construction contractor M (the construction contractor is also denoted as M if it is not specified as any of M1 to M3). An order is placed and materials necessary for the construction are ordered (step S5).

From this ordering stage, the integration system of the first embodiment is used.
The flow of processing by the integrating system of the first embodiment at the time of ordering will be described with reference to the flowchart of FIG.
The sales representative T first accesses the server 30 by the first input / output device 21 (step S200), and displays a menu screen (not shown) (step S201). In this case, although the flow display is omitted, a password is set and access is prohibited even though the user does not have access rights. This menu screen includes a selection unit (not shown) for selecting one of the process management screen WS and the order detail screen DT, and displays the selected screen (steps S202 and S206). Note that both the screens WS and DT may be displayed simultaneously.

  Next, the sales staff T sets a process (construction content) and a construction period using the process management screen WS shown in FIG. In the process management screen WS, for each of a plurality of contractors, the process and work period that have already been input corresponding to each customer CU (house) are displayed. Therefore, it is possible to select a construction contractor M that has a vacant construction period, and an efficient construction contractor setting is possible.

  After the above entry, the save operation is performed by the first input / output device 21, or the entry contents of the process management screen WS are automatically saved in the saving unit 31a of the cost management unit 31 of the server 30 via the communication line 10. (Step S204).

  Furthermore, the sales representative T transmits the process and the construction period to the contractor (step S205). This transmission may be performed using an integration system, or may be performed by other means such as a telephone, e-mail, and FAX without using the integration system.

  The sales person T selects the order detail screen DT (step S206) and displays it (step S207). Depending on the contents of the contract, the order cost data such as the name of the residence, the name of the necessary material, the model number and the manufacturer name, the quantity, the unit price, the amount of money, the order date, etc. Enter in etc. Note that the order detail screen DT is created for each residence as a construction unit, and at the time of initial display, an order detail screen DT for the target residence is newly created.

  In the creation of the order details screen DT related to the new residence, in the first embodiment, the entry control unit 213a uses the third input / output device 23 or the like based on the conversion processing of the conversion unit 213b. The estimate data already created is taken in and converted into order cost data on the order detail screen DT. By this conversion, the name of the material as the cost data, the model number and the manufacturer name, the quantity, the unit price, and the amount obtained by multiplying the quantity and the unit price are associated with the name of the residence, respectively, the material name column SZr, the specification column SYr, The quantity column AMr, the unit price column UPr, and the amount column MOr are automatically input.

Note that the ordering cost data such as quantity, unit price, and amount at this time are the values predicted at the estimation stage, the quantity is the predicted quantity obtained from the design drawing, etc., and the unit price is grasped in advance. Predicted amount, and the amount is also a predicted amount obtained by multiplying the two.
Furthermore, in addition to inputting the order date, the sales representative T sets a desired delivery date according to the schedule set based on the process management screen WS and inputs it to the delivery date column DLr. The data entered on the order details screen DT is automatically saved in the saving unit 31a of the cost management unit 31 of the server 30 via the communication line 10 according to the saving operation by the first input / output device 21 or input. (Step S208: first expense data storage process).
At the time of saving, the quantity measurement drawing data is saved in association with the order detail screen DT. This quantity measurement drawing is a drawing used to confirm the quantity of necessary materials, for example, a design drawing.
Then, to the contractor (wholesaler) TY, the fact that the order has been placed is transmitted to the second input / output device 22 via the communication line 10 (step S209).

  Returning to FIG. 5, when the orderer Or (salesperson T) executes the order in step S5, the contractor TY performs final confirmation of the quantity of necessary materials (step S6), and further, the necessary materials. Confirmation of delivery availability, unit price, scheduled delivery date, and the like (step S7), and thereafter, these response cost data are input to the ordering details screen DT using the second input / output device 22 and stored (first). (2) Cost data storage process).

Details of the processing performed by the contractor TY in steps S6 to S8 will be described with reference to the flowchart of FIG.
The contractor (wholesaler) TY first accesses the server 30 (step S301), opens the order detail screen DT (step S302), and confirms whether there is an order (step S303). If there is an order, the contractor TY confirms the order contents (material name and specification, quantity of material, unit price, delivery desired) (step S304). Next, based on the attached quantity measurement drawing, it is confirmed whether there is any problem in the material name, specifications, and quantity (step S305). That is, it is confirmed whether or not the order from the orderer Or is in accordance with the attached quantity measurement drawing.

Further, the contractor TY finally confirms whether or not there is a change in the material name, specification, and quantity, using a communication means such as telephone, e-mail, FAX, and mail, to the contractor M in charge of the construction (step S305). .
In other words, in external construction work, construction cannot be performed as designed due to the influence of the slope or unevenness of the actual construction site, and the type of necessary materials may change, or the required quantity of materials may change. There are things to do. For this reason, the contractor M is contacted directly and a final confirmation is made whether there is any change in the material name, specifications, quantity, or the like. Here, when there is a change, the orderer Or may be notified of the change, or the reason for the change may be described when filling in in steps S307 and S8 described later. In the first embodiment, it is assumed that a remarks column BR for performing such communication is set on the order detail screen DT.

  Next, the contractor (wholesaler) TY can use the communication means such as telephone, e-mail, FAX, and mail to deliver the quantity of the materials to be ordered, whether the quantity can be delivered, the unit price, and the delivery. The scheduled date and the like are confirmed (step S306). The contractor (wholesaler) TY obtains these answers from the material distributor De, and uses the second input / output device 22 when the quantity, unit price, and scheduled delivery date of the ordered material are confirmed. The value is overwritten in each entry field as response cost data, and stored in the storage unit 31a (step S307). This storage may be performed by a storage operation of the second input / output device 22, or may be automatically performed in conjunction with the entry.

Returning to FIG. 5, when an input is made by the contractor (wholesaler) TY (step S8), the orderer Or makes an approval judgment of the input value (step S9).
Accompanying this approval determination, the controller 213 executes an approval process. The flow of this approval process will be described with reference to the flowchart of FIG. 8. The orderer Or accesses the server 30 (step S221), and confirms whether or not response cost data is input to the order detail screen DT by the orderer TY ( In step S222), if there is an input, it is determined whether or not the response cost data can be approved (step S223).
In other words, the final name, specifications, quantity, unit price, amount of money, and the expected date of delivery of the material entered by the contractor TY are checked for any problems. If there is, the orderer Or (salesperson T) approves the approval, that is, the delivery. When performing this approval, the orderer Or clicks the approval button ab (see FIG. 4) set adjacent to the order detail screen DT. As described above, the ordering party TY outside the orderer Or inputs data related to the material cost via the communication line 10, but an inappropriate name and specification are obtained by interposing a step of obtaining such approval. It is possible to prevent data such as quantity, unit price, amount of money, and scheduled delivery date from being input.

  When the approval from the orderer Or is obtained, the contractor (wholesaler) TY places an order with the material distributor De (S10 in FIG. 5, S309 in FIG. 7). Thereby, the material is delivered from the material dealers De2 and De3 in FIG. 2 directly to the customer (house) CU or from the material dealer De1 via the contractor TY (S11 in FIG. 5).

If the approval by the orderer Or is obtained, the response cost data already entered in the order detail screen DT by the contractor (wholesaler) TY in step S307 is confirmed. These quantities, unit prices, and delivery dates are not estimated prices or planned dates, but are accurate values that have been confirmed. These are before the delivery date, and of course before the invoice is issued. Filled in at the time.
In addition, regarding the materials, the orderer Or does not directly place an order with the material distributor De, but the orderer (wholesaler) TY centrally manages the orderer (wholesaler) TY via the orderer (wholesaler) TY, so Time and effort such as confirmation can be reduced.

  On the other hand, if approval is not obtained, that is, if the orderer Or is not satisfied with the entered price or delivery date, the order is canceled and an order is placed with another contractor (wholesaler) TY. Processing can be performed. Note that the flow of processing in the case of reordering repeats the same flow as described above.

Thereafter, when the work is completely or almost completed and the house is handed over to the customer CU, the so-called “house closing” is performed upon completion of the contract, and the cost of the external work is calculated at this time.
At the time of “closing the house”, as shown in FIG. 9, the salesperson T accesses the server 30 by the first input / output device 21 (step S231), and displays the order details screen DT of the corresponding house. Calling (step S232), the expense column MOr is integrated by the cost integration unit 213c of the control unit 213 (step S233). Note that the integrated value is not limited to that performed at this time, and the integrated value of the amount that has been input so far may be calculated and displayed.
Here, as the cost of the external construction, there are the material cost and the construction cost as described above. However, the integrating system of the first embodiment adds the material cost data to obtain the material cost. use. The final integrated construction cost is calculated by adding the obtained integrated value to the construction cost, for example, at the third input / output device 23 installed in the accounting department outside the integration system. Detailed description thereof will be omitted. In addition, in this accounting department integration, the conversion unit 213b may convert the material cost calculated by the present integration system as data used in the accounting department.

Next, a description will be given of the relationship between ordering of materials, delivery, and integration.
FIG. 10 shows an example of ordering and delivery. In the figure, November 25 is the monthly business closing date Sm1 of the material distributor De. The orderer Or orders three types of materials SZ1 to SZ6 before the closing date Sm1, and the two types of materials SZ1 to SZ5 are delivered before the closing date Sm1, and the material SZ6 passes the closing date Sm1. And delivered.
In such a case, invoices that are the basis of cost calculation are issued on the business closing date Sm1 on November 25 for materials SZ1 to SZ5, but the next closing date for the remaining one type of material Sz6 It will be issued on December 25th.

  In such a situation, when the exterior construction of the target residence has been completed and the residence has been handed over to the customer CU on November 30, when this date is set as the closing date Sm2, the two materials have conventionally been used. SZ1 to SZ5 are accumulated as material costs based on the invoice, but for material SZ6, the invoice issuance date is the closing date of the next month, and it has not reached the ordering party Or at the time of the house closing date Sm2. There was a high possibility of leaking material costs.

  On the other hand, in the first embodiment, not the orderer Or but the contractor (wholesaler) TY receives the response cost data such as the quantity, unit price, amount of money, and scheduled delivery date, which is data related to the material cost, in the second input / output Using the device 22, it is filled in when the delivery date is confirmed with respect to the material dealer De (step S 7). For this reason, the material SZ6 whose delivery date is after the business closing date Sm1 of the following month is also entered before the mansion closing date Sm2, thereby preventing cost omission.

  Further, since the contractor (wholesaler) TY inputs at the time of delivery, the sales person T of the orderer Or sees and inputs the invoice sent from the contractor (wholesaler) TY after delivery. Compared with, it is possible to input accurately and early without causing a transcription mistake or the like.

Next, as shown in FIG. 10, a case where an additional work occurs immediately before “house closing” will be described.
Even when such additional work occurs, the above-described steps S1 to S11 are performed for this additional work.
When performing this additional work, first, the sales person T creates an estimate after determining the work contents (steps S1 and S2). Then, when an internal approval of the estimate is obtained (step S3) and then a contract with the customer CU is established (step S4), in order to start the construction, the construction order is ordered from the contractor M using the process management screen WS. At the same time, an order for the material SZ7 necessary for the construction work is made to the contractor TY using the order detail screen DT (step S5).

  The contractor (wholesaler) TY confirms the contents ordered (item (material name and specification), quantity of the material SZ7, unit price, when delivery is desired), and confirms that there is no change in the item and quantity to the contractor M. Confirm (step S6).

  Next, the contractor (wholesaler) TY can deliver the quantity of the material SZ7 to be ordered to the material dealer De, whether the unit price has been changed, or can be delivered on the desired delivery date. (Step S7), and after obtaining these answers from the material distributor De and confirming the quantity, unit price and delivery date of the ordered material SZ7, the second input / output device 22 is used. These response cost data are input (step S8).

When the input is made by the contractor (wholesaler) TY, the orderer Or (salesperson T) approves (step S9). When the approval is obtained, the contractor (wholesaler) TY places an order with the material distributor De (step S11).

  As described above, even when additional work is performed, the name, model number, manufacturer name, quantity, and unit price of the material SZ7 are input to the ordering details screen DT associated with the target residence. Therefore, the construction material SZ7 added later is correctly associated with the residence when the contractor TY places an order with the seller and the scheduled delivery date is determined.

  Therefore, as in the example shown in FIG. 10, the cost data regarding the material SZ7 whose ordering timing is earlier than the house closing date Sm2 has not been accumulated in the “house closing” in the past. In the first mode, there is a possibility that the “house closing” may be accumulated depending on the delivery confirmation timing.

  In addition, in this additional work, even if the additional work is performed after the closing date Sm2, the cost data is entered on the ordering details screen DT already created for the target house. Therefore, when the construction cost of the residence is confirmed at the stage where the additional construction is completed, the cost of the additional construction can be accurately known.

As described above, in the first embodiment, the effects listed below can be obtained.
a) The second input / output device 22 that can access the server 30 that performs cost control is installed in the contractor (wholesaler) TY, and is a point in time before the contractor TY issues the invoice, and the material distributor Prior to De delivery, when the actual price of the material, the final determined quantity, and the scheduled delivery date are confirmed, the contractor TY displays the quantity and price of the material on the order details screen DT. Response cost data such as scheduled delivery date can be entered.
Therefore, as compared with the conventional case where the invoice issued by the contractor TY arrives and the orderer Or inputs it, it is possible to input it at an early stage, and there is no occurrence of a transcription error. And material costs can be accurately estimated.
In addition, the contractor TY can fill in each response cost data almost at the same time, and there is less variation in the period for obtaining the data than the orderer Or inputs based on the invoice. Is less complicated.

  b) For the response cost data input by the contractor (wholesaler) TY, the sales representative T sets a step for making an approval decision (steps S9 and S223), so that the external contractor TY receives the cost data via the communication line 10. It is possible to prevent an inappropriate price from being input even if the user inputs the.

  c) Since the cost of the material is input using the ordering details screen DT separately from the cost of the construction in calculating the cost of the house, for example, the contractor M has both the construction and the material. Compared with the so-called batch processing of materials, which is received in a lump, the cost can be correctly grasped.

  d) The conversion unit 213b is provided in the control unit 213 of the first input / output device 21 so that the estimate data created by the third input / output device 23 outside the integrating system is automatically displayed in each entry column of the ordering details screen DT. Therefore, it is not necessary for the sales representative T to manually input the data described in the estimate, and the input workability is excellent.

  e) Since the contractor M and the construction period are managed on the process management screen WS, mistakes in ordering the same contractor M during the same construction period can be prevented.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to such embodiment, A various deformation | transformation and substitution can be added in the range which does not deviate from the summary of this invention.

For example, in the embodiment, “house” is shown as a construction unit. However, the present invention is not limited to this. For example, when applied to construction work other than residential construction, the construction target (for example, building, bridge, road) May be used as a construction unit.
Furthermore, although the case where the orderer is the external department of the home construction dealer and the cost of the external work is calculated has been taken as an example, the orderer and the object of cost calculation are not limited to this. For example, the orderer may be a home construction dealer and may be used to add up the overall cost of the construction of the house. Alternatively, the orderer shown in the embodiment may be a contractor M, and may be used to obtain a cost related to materials when, for example, a material construction batch order is received. Alternatively, the construction contractor as the contractor may further input the construction cost on the process management screen WS, and the orderer may add the cost.

Also, in the embodiment, the orderer side uses the second input / output device for the data related to the material (quantity, unit price, desired delivery date, etc.) entered by the first input / output device on the order detail screen. In the case of entering cost data, the example shows that the quantity, unit price, scheduled delivery date, etc. are overwritten. However, the present invention is not limited to this. Order cost data entered by the orderer and the orderer entered it. You may make it write together response cost data.
Further, the response cost data input from the second input / output device may be output as a bill as it is by using the system of the present invention. In that case, compared with the conventional method, the effort of inputting the response cost data can be completely transferred to the trouble of inputting the bill, and the total labor can be reduced.
