METHOD, SYSTEM AND COMPUTER-READABLE RECORDING MEDIUM FOR MANAGING PRICE OF PRODUCT BASED ON PURCHASE HISTORY OF THE PRODUCT}

The present invention relates to a method, a system and a computer readable recording medium for managing a price of a product based on a product purchase history. More specifically, the present invention is to determine the price for the current ordered goods by referring to the reference price, which is the price that is charged to the product when purchasing the product of the cumulative purchase quantity sum of the past purchase quantity and the current order quantity at one time, A method, system, and computer-readable recording medium for allowing a purchaser to purchase a product multiple times in small quantities, such as to obtain a large discount similar to the case of purchasing the product at once in a cumulative purchase quantity.

In electronic commerce based on a communication network such as the Internet, a discount sales method is generally performed in which a seller provides a product (or service) at a discounted price within a limited range in order to achieve a purpose of attracting customers and increasing sales. have. As an example of a conventional discount sales method, when a plurality of buyers purchase a certain quantity or more of a product (aka collective purchase), the product price is discounted. If you give a discount.

However, since the conventional discount sales method is based on the idea of applying a discount only when a plurality of purchases of a predetermined quantity or more occur, a general buyer (for example, a general consumer, etc.) who purchases a small amount of goods. There is a limit to the limited opportunity for discounts.

The limitation of the conventional electronic commerce method may cause various problems in the product distribution structure.

First, from the consumer's point of view, a wholesaler with the ability to purchase a large quantity of goods at the same time goes through several stages of an intermediate distribution process in which a product purchased at a relatively low price is returned to a relatively high price. The problem arises that the burden is greater than the reasonable level. In addition, even from the standpoint of the wholesale and retailer, there is a problem in that a large quantity of products are purchased at a time in order to secure a product at a discounted price, and then, the stock is damaged due to the remaining inventory. .

Therefore, even if a purchaser purchases a specific product in a small amount, the buyer can receive the same discount rate as a general purchase based on his or her purchase history, and can effectively solve the problems of the product distribution structure as described above. There is a need for an e-commerce method.

It is an object of the present invention to solve all the problems described above.

In addition, the present invention by determining the price for the current ordered goods with reference to the reference price which is the price given to the product when assuming that the product of the cumulative purchase quantity sum the past purchase quantity and the current order quantity at a time, Another object of the present invention is to allow a buyer to receive a discount similar to the case of purchasing the product at one time in small quantities, even if the product is purchased several times in small quantities.

In addition, the present invention allows a general consumer who purchases a small number of products several times to directly deal with the producer to receive a discounted price of the product, thereby increasing the price of the product unnecessarily due to a complicated distribution channel It is another object to improve the distribution structure.

In addition, another object of the present invention is to cultivate human sales by allowing a wholesale and retailer to receive a product at a discounted price even if only a predetermined quantity of goods are purchased.

In addition, another object of the present invention is to solve the problem of sales organization management caused by paying a rebate to a human sales person who secures a large amount of goods from the position of the manager of the human sales person.

Representative configuration of the present invention for achieving the above object is as follows.

For reference, determining the current price of the product applied for the buyer's current order. A method of inclusion is provided.

According to another aspect of the present invention, a system for managing a price of a product based on a product purchase history, the purchase history collection unit for collecting the purchase history information of the buyer-the purchase history information is a purchase product, purchase date and time, purchase And at least one of a quantity and a purchase amount, and, for a product currently ordered by the buyer, a current order quantity for the product of the buyer, an accumulation of the product for the buyer, including the current order quantity With reference to the purchase quantity, the reference price corresponding to the price charged to the product, assuming that the product is purchased at the same time as the cumulative purchase quantity, and the cumulative purchase amount immediately before the current order for the product of the buyer. Determine the current price of the product to be applied for the buyer's current order. The system includes parts pricing is provided.

In addition, there is provided another method, system, and computer readable recording medium for recording a computer program for carrying out the method for implementing the present invention.

According to the present invention, even if a purchaser purchases a small number of items in small quantities several times, the buyer may receive the same discount benefits as the purchase of the corresponding product at the same time as the cumulative purchase quantity. The effect of being able to purchase a product is achieved.

In addition, according to the present invention, even if you do not purchase a large number of products at once, it is possible to purchase a product at a reasonably discounted price at each purchase point, so that the general consumer who purchases a small quantity of goods is also a primary distributor It is possible to obtain discounted prices directly from the supplier, thereby simplifying the complex distribution channel.

In addition, according to the present invention, even if you do not purchase a large number of products at once, it is possible to purchase a product at a reasonably discounted price at each purchase point, so even if the wholesale and retailer buys only the required number of products at a discounted price This allows wholesale and retailers to reduce losses due to inventory burdens and to be able to purchase discounted merchandise in a healthy way without being attracted to rebates.

In addition, according to the present invention, a reasonable discount rate can be applied according to the cumulative purchase quantity of the product, away from the practice of providing a rebate to a human sales person who purchases a large quantity of goods, so that the seller (ie, the manager of the human sales person) The effect is to make it possible to manage the sales organization more effectively.

Composition of the price management system

Hereinafter, the internal configuration of the price management system 200 performing important functions for the implementation of the present invention and the function of each component will be described.

2 is a diagram illustrating in detail the internal configuration of the price control system 200 according to an embodiment of the present invention. 2, the price management system 200 according to an embodiment of the present invention, the purchase history collector 210, the price determination unit 220, the buyer management unit 230, the database 240, the communication unit ( 250 and the controller 260. According to an embodiment of the present invention, the purchase history collector 210, the price determination unit 220, the buyer management unit 230, the database 240, the communication unit 250 and the control unit 260 is at least a part of Program modules communicating with the merchant server 300 and / or the purchaser terminal device 400. Such program modules may be included in the price management system 200 in the form of operating systems, application modules, and other program modules, and may be physically stored on a variety of known storage devices. In addition, these program modules may be stored in a remote storage device that can communicate with the price management system 200. On the other hand, such program modules include, but are not limited to, routines, subroutines, programs, objects, components, data structures, etc. that perform particular tasks or execute particular abstract data types, described below, in accordance with the present invention.

First, the purchase history collector 210 according to an embodiment of the present invention may perform a function of collecting history information about a product purchase of a buyer. More specifically, the purchase history information collected by the purchase history collection unit 210 may include information about the purchase product, purchase date, purchase quantity and purchase amount of each buyer, the purchase history information is for each buyer or product The data may be divided and stored in the database 240.

Next, the price determination unit 220 according to an embodiment of the present invention with reference to the purchase history information of the buyer collected by the purchase history collector 210 determines the price of the product that the buyer is currently purchasing It performs the function. According to an embodiment of the present invention, the price determiner 220 purchases the product at the same time as the so-called cumulative purchase quantity, which is the sum of the buyer's current order quantity and the cumulative purchase quantity immediately before the buyer's current order. Assuming, with reference to the base price, the price that can be charged for the product, the buyer can determine the current price of the product he or she currently ordered, so that even if the buyer purchases the product in small quantities multiple times, You can get big discounts just like you buy in quantities.

Here, the reference price refers to a price obtained by discounting an amount corresponding to at least a part of the profit that the seller obtains by selling the cumulative purchase quantity at a time from the normal price of the product, and the seller of the product and the price management system ( 200) may be preset. In general, since the profit of the seller due to mass sales increases as the sales quantity increases, the reference price of the product may be set lower as the cumulative purchase quantity of the corresponding product increases. For example, the reference price according to one embodiment of the present invention is set to be lowered linearly (ie at equal intervals) or nonlinearly (ie at non-equal intervals) as the cumulative purchase quantity increases. Can be. Meanwhile, according to an embodiment of the present invention, when the cumulative purchase quantity of the product is larger than the preset value, even if the cumulative purchase quantity of the corresponding product increases, the reference price of the corresponding product is no longer lowered. The lower limit value may be set. The reference price will be described in more detail with reference to FIGS. 3 and 4 below.

More specifically, the price determining unit 220 according to an embodiment of the present invention, the cumulative purchase quantity (APQ) and the reference price (Reference Price) in the cumulative purchase quantity (APQ) for a particular product of a particular buyer Multiplying each other by RP), subtracting the accumulated purchase amount before the current order for a particular product of a particular buyer from the calculated amount of the multiplication product, and then subtracting the amount calculated as the subtraction result. The amount divided by the present order quantity (POQ) for a particular product of a buyer may be determined as the present price (PP) of the specific product for a specific buyer. The above product price determination method is represented by Equation 1 below.

&Quot; (1) "

PP = {(APQ x RP)-APAB} / POQ

According to Equation 1, the amount of money required when a buyer buys a total of n items at a time is equal to the amount of money spent when a buyer buys a total of n items at multiple times. Even if you purchase a small number of times several times, you can get the same big discount as if you purchase the same amount of cumulative purchase at once.

3 and 4 exemplarily illustrate a process of determining a price of a product according to an embodiment of the present invention. For reference, FIG. 3 and FIG. 4 show the current price of the product a applied to the buyer A when the specific buyer A purchases the specific product a one by one. 3 and 4, the normal price of the product a may be set to 10,000 won, the reference price of the product a may be set lower as the cumulative purchase quantity increases, for example, the reference price of the product a Is 9,000 won for one cumulative purchase, 8,777.8 won for two cumulative purchases, 7,000 won for ten cumulative purchases, and 3,333.3 won for fifty cumulative purchases. The lower limit of the reference price of the commodity a may be set to 3,333.3 won.

First, referring to FIG. 3, (i) in the first purchase, when the purchaser A orders one product a, the cumulative purchase quantity is one and the immediately preceding cumulative purchase amount is zero. The reference price of commodity a in the case of 9,000 won may be determined as the current price of commodity a for Buyer A, and (ii) in the second purchase, if Buyer A orders another commodity a again, Since the quantity is 2 and the previous cumulative purchase amount is 9,000 won, the result is calculated by subtracting the previous cumulative purchase amount of 9,000 won from the amount of 17,555.5, which is the product of the base price of 8,777.8 won, which is the cumulative purchase quantity, multiplied by 2 cumulative purchase quantities. The won 8,555.3 may be determined as the current price of article a for Buyer A. Similarly, (iii) In the tenth purchase, when purchaser A orders another product a again, the cumulative purchase quantity is 10 and the previous cumulative purchase amount is 65,000 won. The current price of commodity a for buyer A may be determined by subtracting the previous cumulative purchase amount of 65,000 won from the cost of 70,000 won multiplied by the cumulative purchase quantity of 10 times the price of 7,000 won.

On the other hand, the above embodiment has been described by taking an example of the case where the quantity of the product a currently purchased is one, but is not necessarily limited thereto. Specifically, it may be assumed that the buyer A orders five goods a in the eleventh purchase. In this case, the cumulative purchase quantity is 15 pieces and the previous cumulative purchase amount is 70,000 won.In this case, if the base price is 15,500 won, the cumulative purchase quantity is 6,500 won. The current price of commodity a for Buyer A may be determined by subtracting the previous cumulative purchase amount of 70,000 won from the amount of 15,500 won, which is 15 times the amount of 27,500 won divided by the current purchase quantity of 5,500 won.

Next, referring to FIG. 4, (i) in the 41st purchase, when the purchaser A orders one product a, the cumulative purchase amount is 41 and the immediately preceding cumulative purchase amount is 166,666.7 won. The current price of article A for Buyer A is determined by subtracting the previous cumulative purchase amount of 166,666.7 won from the base price of article a, 4,083.3 won, multiplied by 41 accumulated quantities. Can be. Furthermore, (ii) In the 46th purchase, when the purchaser A orders another product a again, the cumulative purchase quantity is 46 and the immediately preceding cumulative purchase amount is 168,750 won. The current price of commodity a for buyer A can be determined by subtracting the previous cumulative purchase amount of 168,750 won from the price of 3,666.7 won multiplied by the cumulative purchase quantity of 46, and the current price of commodity a for buyer A. Means a refund of KRW 83.3 to Buyer A. That is, in some intervals where buyer A's previous cumulative purchase amount for product a becomes greater than buyer A's cumulative purchase quantity for product a multiplied by the reference price, buyer A may purchase additional product a It can be confirmed that the predetermined amount can be returned. From another point of view, in the period from the 41st purchase to the 50th purchase, the sum of the amount paid by the buyer equals the sum of the amount refunded to the buyer, so that the buyer must buy from the 41st purchase to the 50th purchase. You will be able to receive free goods during the period of.

For reference, the above description is made without any limitation in determining the current price of the product according to the purchase history information, but is not necessarily limited thereto, and the current price of the product may be determined by referring to the purchase history information for a certain period of time. You could do it. For example, if a certain period is set to 5 years, the current price of the product is calculated based on the purchase history information for 5 years, and after 5 years have elapsed, the purchase history information for the first time is reset (reset). It may be assumed that the current price of the commodity is determined.

On the other hand, the buyer management unit 230 according to an embodiment of the present invention may perform a function of differently applying a discount rate system of the product price applied to each buyer according to the buyer's qualification information or purchasing capacity (capacity). For reference, in view of the fact that a buyer can resell a product purchased by another person, the concept of a "purchasing ability" of a buyer may also be understood to mean the selling ability of the buyer. For the sake of consistency, the concept will be referred to as a "purchasing ability."

For example, commercial law may prohibit the regular sale of goods to regular buyers at discounted prices exceeding a predetermined discount rate. In this case, the buyer management unit 230 may be a sole proprietor, sales member, or shareholder. For example, it is possible to prevent a price of a product for a general buyer except the buyer determined to have a predetermined qualification, such as a buyer who paid a deposit, from being discounted above the predetermined discount rate from the normal price of the product.

FIG. 5 is a diagram exemplarily illustrating a configuration in which a discount rate of a product price is changed according to a qualification of a buyer according to an embodiment of the present invention.

Referring to FIG. 5, it may be assumed that the maximum legal discount rate that can be applied by a general buyer is 30 percent. In this case, the purchaser management unit 230 according to an embodiment of the present invention may allow the general purchaser to receive only the discount rate corresponding to the first stage section. More specifically, the cumulative purchase quantity of the general purchaser exceeds 10 pieces. If you do not do this, you can provide discount benefits in accordance with the discount rate system mentioned in Equation 1 above, but if the cumulative purchase quantity is 11 or more, the discount rate exceeding 30% may not be applied. The lower limit can be set. In addition, the purchaser management unit 230 according to an embodiment of the present invention corresponds to the first and second stage sections of the buyers with predetermined qualifications (for example, individual business owners, sales members, shareholders, buyers who have paid a deposit). All the discount rate can be applied so that a qualified buyer can receive all the discount rate increase benefits according to the cumulative purchase quantity without limit of 30% discount rate.

For another example, the purchaser management unit 230 according to an embodiment of the present invention may perform a function of selecting a buyer having a purchase capacity of more than a predetermined level based on the purchase history information of the buyer, and purchasing For buyers selected as having a predetermined level or more, a function may be performed so that a certain excess discount rate is applied regardless of the cumulative purchase quantity.

6 is a diagram exemplarily illustrating a configuration in which a certain excess discount rate is applied according to a purchasing ability of a buyer according to an embodiment of the present invention.

Referring to FIG. 6, it may be assumed that a purchaser's purchasing ability is evaluated based on a monthly average purchase quantity for the last three months. In this case, the buyer management unit 230 according to an embodiment of the present invention, 67% discount regardless of the cumulative purchase quantity of the buyer in the so-called small wholesale stage that the average monthly product purchase quantity is 51 or more and less than 100 The product can be purchased at a set price. Here, when comparing only the discount rate, the discount rate in the retail stage of FIG. 6 and the discount rate when the cumulative purchase quantity of FIG. 4 is 50 may appear to be the same, but the buyer corresponding to the retail stage of FIG. Irrespective of the fact that the discount can be applied consistently, the cumulative purchase quantity of FIG. 4 can be regarded as being able to purchase a product under favorable conditions than the buyer having 50 items.

6, the purchaser managing unit 230 according to an exemplary embodiment of the present invention provides a cumulative purchase quantity in the case of a buyer who is in a so-called middle-wholesale stage in which the average monthly product purchase quantity is 101 or more and less than 300. Regardless of the cumulative purchase quantity, buyers of the so-called wholesale / sales stage with a monthly average product purchase of 301 or more are entitled to purchase the product at a 71 percent discount. Can be purchased.

In the above embodiment, only a configuration in which a predetermined excess discount rate is applied to the corresponding product only in the case of a purchaser having a purchase ability of the product more than a predetermined level is described, but the embodiment of the present invention is not necessarily limited thereto. That is, according to another embodiment of the present invention, even if a purchaser who is evaluated as having a purchasing ability of a certain product or more than a predetermined level purchases a product other than the specific product, a certain excess discount rate is applied regardless of the cumulative purchase quantity. You might consider an example of this.

On the other hand, the purchaser management unit 230 according to an embodiment of the present invention, the first buyer who can purchase the product at a relatively low price through the price management system 200 of the present invention to purchase the product at a higher price than their own To resell the product purchased by the second buyer to the second purchaser. In this case, the selling price of the product of the first buyer may be determined by the price determination method of the price management system 200 according to the present invention.

For example, the buyer B corresponding to the large wholesale stage of FIG. 6 finds that the product b purchased at a 78 percent discounted price can be applied only to the discount rate of the first stage section of FIG. 4, for example, online or offline. Reselling to Buyer C at a 30 percent discount would help foster human sales.

In addition, the purchaser manager 230 according to an exemplary embodiment of the present invention may provide at least some of the profits from the buying behavior of the second buyer to the first buyer when the first buyer contributes to the buying behavior of the second buyer. Distribute function.

For example, if Buyer D makes a predetermined promotion to Buyer E through online or offline, and Buyer E purchases a certain product due to the promotion, the buyer takes some of the profits from Buyer E's purchase. You can distribute to D.

On the other hand, the database 240 according to an embodiment of the present invention may store the purchase history information of the buyer. More specifically, the information about the purchase goods, the purchase date, the purchase quantity, and the purchase amount of each buyer may be stored in the database 240. Such purchase history information may be stored in association with the identification information of the buyer or the product. Can be.

In addition, the database 240 according to an embodiment of the present invention may store information on whether the buyer is entitled to a discount exceeding the legal discount rate and information on the purchase ability of the buyer.

Although the database 240 is illustrated as being included in the price management system 200 in FIG. 2, the database 240 is separate from the price management system 200, as required by those skilled in the art of implementing the invention. It may be configured. On the other hand, according to the present invention, the database 240 is a concept that includes a computer-readable recording medium, and refers to not only a narrow database but also a database in a broad sense including a data system based on a file system. If a simple log set can be retrieved to extract data, it is included in the database 240 according to the present invention.

The communication unit 250 according to an embodiment of the present invention performs a function of enabling data transmission / reception from / to the price management system 200.

The control unit 260 according to an embodiment of the present invention controls the flow of data between the purchase history collector 210, the price determiner 220, the buyer manager 230, the database 240, and the communicator 250. Perform the function. That is, the control unit 260 according to the present invention controls the flow of data from the outside or between each component of the price management system 200, thereby purchasing purchase unit 210, price determination unit 220, buyer management unit In operation 230, the database 240 and the communication unit 250 control to perform unique functions.
