Description

Providing a repurchase estimate using the agreement search code, and the repurchase method and devices thereof {Providing a repurchase estimate using the agreement search code, and the repurchase method and Devices thereof}

The present invention is a device for providing a repurchase quotation using a contract search code, a repurchase method through the same, and a device for implementing the same. To be described in more detail, the purchase history of the business operator through the construction material sales platform is provided in the purchase method and repurchase method of building materials. When the certified purchaser ID information and the contract search code assigned by the operating program of the business related to construction material information are entered into the buyer terminal, repurchase quotation information is generated according to the previous purchase quotation information, quickly expressing intention to repurchase. A repurchase request is made by entering a contract search code, and the repurchase quotation information generated in the data server managed and stored on the business operator's server is sent to the buyer's terminal based on the purchase quotation information in which the buyer ID information and the contract search code related to construction material information are entered. The repurchase quotation information transmitted and confirmed is checked, and if there is no change in the confirmed repurchase quotation information, the repurchase quotation information is transmitted and approved to the previous seller on a priority basis, and the repurchase of building materials is concluded. Characterized by a repurchase conclusion stage. It relates to the provision of a repurchase quotation using a contract search code given by a business server, a repurchase method through the same, and a device for implementing the same.

In particular, technical matters related to the present invention include the purchaser ID of the purchaser or repeat purchaser, seller, and purchaser with prior purchase history certified on the construction material sales platform operated by the business operator for the quotation for construction material information. When information and contracted building material information (search code) are entered and a repurchase is displayed using a contracted search term that quickly indicates repurchase, the buyer ID information and contracted building material information (search code) are entered into the entered information (data). When the repurchase quotation generated from the data server managed and stored on the business's server is transmitted to the repurchaser's terminal and displayed and confirmed, there is no change in the buyer's personal/goods information (search code, quantity, delivery address, etc.) and the price of the goods. In this case, there is an advantage in that the repurchase quotation and repurchase agreement and contract conclusion with Seller 1 are quickly concluded and the repurchase transaction is quickly unified, and if the buyer's personal information/goods information/price information, etc. are changed, the repurchase quotation The revised repurchase quotation is sent to the repurchaser's terminal and confirmed (displayed), and after confirming the seller's revised product information/price information, the changed repurchase quotation is agreed upon and sent to the seller to conclude a repurchase, or If the revised repurchase quotation cannot be agreed upon after checking the seller's revised product information/price information, a repurchase contract is made based on the repurchase quotation information transmitted and confirmed to the repurchaser's terminal in order to reselect additional sellers. It relates to the provision of a repurchase quotation using a contract search code stored on a business server, whereby repurchase quotations are sent to additional agreed sellers and repurchase is agreed upon and concluded, a repurchase method through the same, and a device for implementing the same.

Recently, as interest in quality of life has increased, there has been an increase in the number of private construction cases among the general public who want to construct their own private houses, country houses, or townhouses. In particular, as the construction of various private houses such as wooden houses such as panels or wood that can be assembled, H-beam rebar prefabricated houses, and container box-type improved houses increases, the market for building materials required for construction, such as offline markets, and the online Internet. Quotation information services related to orders and sales in shopping malls, etc. are becoming more diverse. While various sales and quotation methods related to building materials are becoming more diverse and the number of sellers is steadily increasing, objective price standards are not set, so the buyer's satisfaction with building materials is lower than the required building construction area in the form of conventional sales methods. After checking the inventory amount, price, delivery date, etc. of the currently selling vendor over the phone, including the number (quantity) of rebar or wood structure according to the balance, the amount of cement bags (40 kg), etc., and providing an order quotation (information), sales are made. The method of selling after checking with the transporter whether the buyer can transport the building materials desired by the buyer within the delivery date is still prevalent. In particular, building materials such as rebar and H-beams required for building construction are produced and supplied by specific steel producers in Korea, and there are limited local sales companies that can store and manage these rebars, and construction is carried out according to production time and required quantity. Since the prices of materials-related purchase items often vary dramatically, the problem of a special purchasing and sales structure that makes it difficult for buyers to easily purchase building materials and carry out construction work on their own still exists. In particular, building materials related to individual building construction have the characteristic of purchasing multiple items at the same time, and specific manufacturers related to building materials, real-time fluctuations in raw material prices, and building materials produced by large companies are not sold to small businesses or individuals. Various problems that are not thought of in general industrial products online shopping malls may arise, such as selling at high prices considering various circumstances such as transportation, etc.

To explain this in more detail, in relation to the prior art related to the sale of conventional building materials and construction construction, generally, when a buyer wants to purchase building materials, he or she visits the store or sales website that sells the building materials, etc. It was customary to select the quantity and options, receive an estimate accordingly, and then construct the building materials. In this method of purchasing building materials, the price or seller varies depending on the type or option of the building material, so not only does the buyer not easily obtain the information he or she wants, but the buyer also needs to obtain information such as specifications (standards) and options for the building material in question. If the information was not accurately known, purchasing building materials and constructing the building would be virtually difficult. For example, when trying to construct a personal building such as slab or wood, various types of building materials such as rebar, steel plate, aluminum, copper pipe, and copper plate are required depending on the type of building. Among them, construction materials such as rebar, steel plate, and steel beam are required to be There is a problem that the supply period often changes depending on whether a large quantity is needed at a certain time or depending on the supply and demand requirements and prices of raw materials.

In particular, sellers of building materials related to the present invention, such as reinforcing bars and steel beams, required for construction, have various price differences depending on the production scale, and even for the same type of reinforcing bars, the prices of raw materials, etc. change depending on the production period, so sellers There is a problem with prices etc. being inconsistent for each product. In addition, when constructing a building, producers or sellers (Hyundai, POSCO, Dongkuk, etc., hereinafter referred to as 'sellers') and transportation are required according to the buyer's construction material information, building environment, location, delivery date, etc. (hereinafter referred to as 'construction construction information'). Depending on the personnel and skills required for equipment, heavy equipment, and the manpower that operates them (transportation manpower, heavy equipment manpower, construction material specialist manpower, and labor manpower), construction material prices and manpower costs fluctuate greatly, and the necessary manpower is not supplied quickly and inexpensively. There was a problem that I couldn't do. In addition, the unit price of the construction material quotation (hereinafter referred to as 'construction quotation information') desired by both the seller and the buyer and the delivery date of construction construction vary widely, so the lowest price quotation information and supply/purchase information are provided accordingly. There are many cases where a transaction cannot be established, and even if the seller is selected based on the quotation information and the construction materials are supplied on time by the transportation employee, in addition, the selection of heavy equipment required for construction of the construction materials, non-employees of the heavy equipment, and construction materials Problems have arisen in which it is not easy to obtain a pool of construction-related building materials experts or simple laborers, and as a result, there are many difficult problems to personally perform in relation to the construction of small-scale buildings such as private buildings or country houses using such building materials. are faced with

Recently, e-commerce through Internet shopping malls has become common for the sale and purchase of most general products, and the processing of electronically written quotations while shopping on the Internet using consumers' wired and wireless communication terminals is becoming increasingly common. However, quotations for construction materials or rebar materials are still made by selecting the relevant seller, and the purchasing company of the above materials, etc., calls them one by one or confirms the unit price of the quotation through documents such as fax or email through a known conventional supply company. After confirming again whether the quoted unit price is acceptable, the final quotation is provided or the unit price of the previously provided quotation is revised and agreed upon before purchasing the building materials. When constructing the building materials and construction purchased in this way, the building environment, location, delivery date, etc. ( Manpower such as producers or sellers (Hyundai, POSCO, Dongkuk, etc.), transportation equipment, heavy equipment, and manpower (transportation manpower, heavy equipment manpower, construction material specialist manpower, labor manpower) required to operate them according to (hereinafter referred to as 'building construction information'). As construction-related personnel are sought after checking personnel information offline (via phone) according to supply and construction work, it is difficult to systematically computerize the provision of personnel estimate information or personnel quotation forms for employees. It was. Likewise, with regard to building materials, a typical buyer must directly research the product name, standard, specification, and quantity for each purchased item and request a purchase from the seller. Prior to this, he or she must request quotations from multiple sellers for each item. In order to negotiate the price, the quotation for the order contents is delivered via fax or e-mail, and then confirmed offline by phone, etc., the unit price of the quotation is confirmed, and the quotation for materials revised accordingly is provided again. There was a problem. According to this off-line method and system for providing estimates for construction materials and manpower, the consumer first searches for sellers who produce or supply materials to be purchased, and then directly calls, faxes, or emails the sellers found through the search. When the building materials are purchased by contacting the company and requesting the provision of a quotation, the necessary producers are required according to the purchased building materials and the building environment, location, delivery date, etc. (hereinafter referred to as 'building construction information') during construction. Or offline (by phone), which is limited depending on the supply of manpower and construction work such as sellers (Hyundai, POSCO, Dongkuk, etc.), transportation equipment, heavy equipment, and the manpower that operates them (transportation manpower, heavy equipment manpower, construction material specialist manpower, labor manpower). By checking the manpower information of the company and then looking for construction-related workers, there is generally a waste of time and manpower due to the quotation work.

For reference, according to the previously known invention, the technical configuration disclosed in Patent Publication No. 2002-0045358, the published unit price data required for the construction of the conventional interior and the comprehensive data of materials and construction equipment flowing from regional factories are refined to create a price review table. has the advantage of allowing interior design consumers to easily check the resources used in construction and pay a reasonable price, and to increase work efficiency by guaranteeing objectivity and expertise to experts, but it is still an important part of the production, supply and sales of building materials. There still remain problems that cannot be resolved, such as quantity and supply issues and deviations due to real-time price changes, as well as disadvantages and inconveniences caused by buyers' multi-item order estimates and construction delivery dates. In order to solve this problem, the present inventor has developed a collaboration platform for buyers and sellers related to construction materials construction, so that the buyer's construction construction can be completed quickly within the delivery date, and various solutions related to construction materials and construction materials are provided accordingly. We have applied for a patent and received a patent registration for a multi-item estimating method for building materials and a device that implements it using a building material collaboration platform that can determine the cost of items at once and perform construction at the lowest price or quickly (patent registration number 10-2471767, Patent registration number 10-2043894)

In other words, in the case of a new configuration of the present invention, the present applicant seeks to solve the problem of waste of time and manpower due to the conventional construction material purchase quotation work, A construction materials sales collaboration platform that provides the lowest price quotation information and improves the establishment of supply/purchase transactions as the unit price of the quotation (hereinafter referred to as 'construction quotation information') and delivery date of construction construction vary widely. A method of selling building materials using and a device for implementing it were provided. However, although the above patented invention had an aspect of an excellent technical structure that provided the lowest price or differential unit price for building materials, it lacked the provision of a repurchase quotation for rapid and repeated repurchase buyers, so the conventional purchase quotation included building material items, quantity, delivery address, etc. The material product information and the buyer's personal information are re-entered, and the applicant bids the lowest price again through the construction material sales collaboration platform (Doso Mall) provided by the above applicant. Negotiation process (purchase quotation is sent to the sellers, In order to solve the problem of concluding a repurchase price by confirming the lowest price purchase quotation again through a bidding and price negotiation procedure such as confirmation and resending of the lowest price sales quotation), the repurchase price is negotiated with the sellers. Information and purchase information of building materials are abbreviated into codes that are easy to search, quickly managed and stored on the server of the business operator's building materials sales collaboration platform, and provision of repurchase quotations using data-formatted contract search codes, methods of repurchase through this, and We would like to provide a device that implements this. The configuration of the new invention in this regard is described in detail as follows.

Therefore, first, with reference to Figures 1, 2, 3, and 4, the provision of a repurchase quotation using a contract search code according to the present invention, the repurchase method through the same, and the device for implementing the same will be described in detail.

The configuration for realizing the present invention includes a purchaser terminal (200), seller 1, 2, 3... linked in real time with the business server (100n). n (seller terminal: 300n) and communication means (devices) connected thereto, business server (100n), brokerage server (101), data server (102), central operation server (100), construction material quotation program, and operation thereof. In order to explain the o/s (operating software), etc., the overall configuration diagram is described based on Figure 1 as follows.

The provision of a repurchase quotation using the contract search code of the present invention, a repurchase method using the same, and a device implementing the same include the business operator's brokerage server 101, which brokers building material collaboration information, the business operator's central operation server 100, and the data server ( 102), a buyer terminal 200 and a seller terminal 300n that can connect to the business server 100n, and a mediation server of the business server 100n linked to the buyer terminal 200. Real-time location information can be checked at (101), and in the trade of building materials, raw materials such as rebar, copper plate, and H-beam, which mainly make up the building materials, fluctuate greatly, so the price of building materials fluctuates significantly (architectural materials). Real-time price fluctuations are severe even when materials are delivered), when repurchasing building materials to solve the problem of the supply of building materials not being smooth from a specific country (China, Russia, South America, the United States, Australia, etc.) or a specific production/manufacturing site. The business server (100n) consists of the business's central operation server (100) and data server (102), which presents published prices that are real-time updates to the prices presented by professional public announcement agencies or companies linked to the business's construction material sales platform. It is built.

Each specific process of the present invention is explained by Figure 3 (flow chart) showing the process of providing a repurchase quotation using the contract search code of the present invention, a repurchase method using the same, and a device for implementing the same in order to realize the above purpose. It is as follows.

first. In order to solve the problem of waste of time and manpower due to the conventional construction material purchase quotation work, the present applicant provides the business's construction material sales service with respect to the construction material quotation information desired by both the seller and buyer of the existing applicant's patented invention. When the certified buyer ID information with purchase history through the platform and the contract search code assigned by the quotation program of the business related to construction material information are entered into the buyer terminal, repurchase quotation information is quickly created according to the previous purchase quotation information. Allows you to express your intention to repurchase. However, although the above patented invention had an aspect of an excellent technical structure that provided the lowest price or differential unit price for building materials, it lacked the provision of a repurchase quotation for rapid and repeated repurchase buyers, so the conventional purchase quotation included building material items, quantity, delivery address, etc. Material information, personal information such as buyer ID, resident registration number, address, etc. are re-entered and the applicant bids the lowest price again through the construction material sales platform (Doso Mall) of the business provided by the above applicant, and a consultation process is conducted with the seller who was selected first ( The present invention is to solve the problem of confirming the lowest purchase quotation again through a bidding and price negotiation process such as sending the purchase quotation to the sellers, confirming and resending the lowest price sales quotation, and then negotiating the repurchase price with the sellers to conclude a repurchase price. The structure is abbreviated into an easy-to-search code (agreement search code) where the buyer's personal information and purchase information of building materials are quickly managed and stored on the server of the business's building materials sales platform and quickly searched using a data-formatted code. We would like to provide a repurchase method and a device for implementing it using a repurchase quotation.

Therefore, the business server 100n (central operation server 100, brokerage server 101, business data server 102), buyer terminal 200, and multiple sellers related to the building materials sales platform according to the configuration of the present invention. Terminal (300n), (Re-purchaser in case of re-purchase agreement) (DB) (120) (Buyer personal information (121), building material information (122), building construction information (123), purchase estimate information ( 124), purchase successful bid information (125)), (in case of re-sale (re)seller (DB) (130) (seller personal information (131), sold construction material information (132), sales delivery date information (133) ), sales quotation information 134, sales successful bid information 135), etc. can be said to be the same. However, in addition to the above-mentioned technical configuration, repurchase quotation information is provided, managed, and stored ( Through the re-purchase data server and the (re-)purchase quotation program that operates it, rapid and repetitive re-purchase quotations are quickly generated using the search code of the personal information of the agreed buyer and the search code of building material information, and are provided to buyers and sellers. It can be said to be a new configuration that provides a technical configuration procedure through which a contract is transmitted and agreed upon.

In this regard, the new configuration of the present invention will be described in detail below. First, in a conventional building materials sales platform, when a buyer purchases building materials for the first time, the buyer sends the purchaser to the buyer terminal (200) through the business' building materials sales platform built on the central operation server (100) of the business server (100n). When logging in after entering personal information such as buyer ID, resident registration number, and address, the contract search code given by the business's quotation program related to the certified buyer ID information with purchase history and construction material information is entered into the buyer terminal. (Before) perform a repurchase request step (S100) by entering a contract search code to quickly express repurchase intention by generating repurchase quotation information according to the purchase quotation information, and contract search code related to the buyer ID information and building material information A repurchase quotation information confirmation step (S200) in which the repurchase quotation information generated in the data server 102, which is managed and stored in the business's server 100n according to the input purchase quotation information, is transmitted to the buyer terminal 200 and confirmed; After performance, depending on whether there is a change in the confirmed repurchase quotation information, (1) first, if there is no change in the confirmed repurchase quotation information, the repurchase quotation information is transmitted and approved to the previous seller as a priority, and construction materials A repurchase conclusion step (S300) in which a repurchase is concluded; a repurchase quotation using a contract search code is provided and a repurchase method is performed through this.

To summarize this briefly, (1) central operation of the business server (100n) is performed by the business server (100n) and is connected to the buyer terminal (200) and a plurality of seller terminals (300n) to transmit and receive information. When the certified buyer ID information with purchase history and the contract search code given by the business's quotation program related to building materials information are entered into the buyer's terminal through the business's construction materials sales platform built on the server 100, the previous (從前) If there is a request for repurchase by entering an agreement search code to quickly express repurchase intention by creating repurchase quotation information according to the purchase quotation information, if there is no change in the repurchase quotation information confirmed above, the repurchase quotation information will be sent to the previous seller on a priority basis. It has the characteristic of quickly carrying out the repurchase conclusion stage in which the repurchase of building materials is concluded after transmission and approval.

However, depending on whether there is a change in the confirmed repurchase quotation information, (1) First, if there is a change in the confirmed repurchase quotation information, the previous buyer or seller sends the changed repurchase quotation information to the buyer terminal through the business server. Or, the changed repurchase quotation information transmission and confirmation step (S310) in which the changed repurchase quotation information is sent to the seller terminal and the repurchase decision is confirmed again; And, depending on whether the repurchase quotation information is confirmed and the bid is successful, next, the changed repurchase quotation information is confirmed and If the bid is successful, it has the characteristic of being performed as a repurchase conclusion step (S410) in which the repurchase of building materials is concluded according to the repurchase quotation information changed according to the previous buyer and seller.

In addition, if the previous seller's successful bid for the secondly changed quotation information is not successful, the secondly changed quotation information is replaced by an additional seller and the repurchase of building materials is additionally performed in the repurchase conclusion stage (S420). If the previous seller's bid is not successful with respect to the second changed purchase quotation information, the repurchase conclusion step (S421) in which the repurchase of construction materials is concluded by replacing it with another subordinate seller who offered the lowest price for the second changed purchase quotation information ); It is composed of: In addition, if the ranking of the lowest price for the above secondary changed quotation information is tied, delivery date information among multiple additional sellers, construction material transaction volume and transaction amount on the construction materials sales platform, or construction material inventory volume that can continue transactions It is characterized by providing a repurchase quotation using an agreement search code and having a repurchase method through it;

After purchasing these first building materials, the personal information code that the buyer wishes to purchase (a combination of multiple characters such as abbreviated English letters, numbers, and special symbols for easy searching), and building material information (search codes are abbreviated, making it easier to search). By simply entering the search code (consisting of a combination of a number of characters such as abbreviated English letters, numbers, special symbols, etc.) on the buyer's terminal, the conventional data managed and stored in the data server 102 of the business server 100n related to the building materials sales platform If the purchase quotation is marked as a repurchase quotation and displayed, and the buyer who has confirmed it does not change the personal information or building material information in the repurchase quotation, it is immediately sent to the previous seller, and the buyer's repurchase quotation information is immediately concluded, and the concluded building material information is The goal is to provide a repurchase method that provides quick repurchase estimate information with a contract search term that allows building materials to be traded quickly and repeatedly so that they can be delivered, and a device that implements the same.

First, if you provide a search code that abbreviates the buyer's personal information into a search term, it is as follows.

For example, a type of electronic record that records the personal information of the previous purchaser, and is a device with information processing capabilities, such as a computer. In particular, in the fields of electronic documents created, transmitted, received, or stored in electronic form by a document processor such as a word processor, the name (name) of the individual/corporation, resident/corporation registration number (business registration number), etc. must be entered like normal personal information. Registration number), address, delivery address, delivery date, etc., letters, special symbols or numbers can be abbreviated (search code), and the building material information includes the items of building materials, as well as the quantity, specification, size (size), and weight. You can enter various material information such as , delivery status, etc. In other words, by entering the information of the minimum purchase quotation described in this way, the buyer can use the construction material quotation program through the construction material sales platform built on this business server (100n) (central operation server 100), which can be easily searched and quickly applied. The search code selected by the buyer is contracted, coded, managed and stored through the O/S and can be used through the repurchase quote data server. For example, when Buyer 1 purchases rebar from Dongsan Co., Ltd., collaboration in sales of building materials is possible. In the platform's operating system, the assigned contract search term is divided into personal information and building material information and stored and managed again as DS1 (personal information search code)_SD400_#10 (building material information search code). If the item is quickly requested to be repurchased, if the search term DS1_SD400_#10 is entered after authenticating Buyer 1 to request a repurchase of DS1_SD400_#10 on Buyer 1's terminal, the repurchase quotation will be sent to the previous Seller 1 and repurchase with Seller 1. By concluding the contract, Buyer 1 has the effect of quickly and repeatedly repurchasing building materials and quickly concluding a contract for repeated repurchase on the building materials sales platform built by the present inventor.

In other words, in the case of a buyer, when providing a repurchase quotation, the present invention is designed to solve the problem of wasting a lot of time and effort by manually searching the buyer's personal information, purchase item information, purchase price information, seller information, etc. and negotiating the price. The operating system for the material sales collaboration platform was provided.

The search code for the personal information of the buyer (repurchaser) or seller (reseller) can be selected as an agreed upon search language using letters, numbers, special symbols, etc. such as English. For example, in the case of Dongsan Co., Ltd., the English initials DS1 are used. You can select it (granted according to the order of contract terms determined by the business operator_granted once upon personal information verification), and information such as building material items, specifications, materials, and quantities is given by English abbreviations and quantities, for example, with the special symbol #. In addition, known mathematical symbols or measurement symbols can be used as unit quantity measurement characters. Weight can be expressed in kg t, etc., and length can be expressed in cm, m, etc.

For example, if Dongsan Co., Ltd. orders a quantity of steel bar (search code SB_#100m) or 50 tons (search code SB_#50t), after Buyer 1 authenticates, send “ DS1_SD400_#10t” is written, and if it is made in Korea, KR is additionally written as “DS1_SD400_#10t_KR” and sent to the business’s server. The information in the repurchase agreement is immediately created and transmitted based on the previous purchase agreement. In this case, since the highest priority repurchase seller is specified as the previous seller, Seller 1 (S1 - seller) is added and DS1_SD400_#10t_KR_S1 (former seller 1) is displayed to display information on the repurchase quotation. If the repurchase information for the building material is H-beam, it is displayed as DS1_SD400_#10t_KR_S1, and the seller's information on the repurchase quotation is also written and generated and sent to Seller 1's terminal to confirm the repurchase information. and approval may be possible immediately. Here, of course, SD400 is a rebar, and 400 can be displayed together with the rebar length_100m. DS1_SD400_#10t_100m_KR_S1 Therefore, in the case of H-Beam (HB), a search code expressing both length and weight can be entered by agreement. If the above embodiment is additionally repeated, it can be indicated by writing as DS1_HB500_#10t_KR_S1, and the use of this liquid crystal search code can be modified into various languages and symbols by the quotation program of this business operator, and rights are limited to these examples. Please note that this does not work.

And the business server consists of a relay server, a data server, and an operation (central) server, and the business server has terminals (smartphones, PCs) such as buyers and sellers/shippers that can access the conventional building materials sales collaboration platform. , laptop, wireless PDA, etc.), and is a specialized public price linkage server that publishes the prices of materials such as rebar, H beam, etc., where you can check information such as the price of construction materials, and the price information of the above building materials. Through this, the price information of the real-time business operator's construction material sales platform is updated and announced to buyers and sellers.

The present invention according to the following examples is not limited to the described examples, and can be used by changing the application area, and various modifications and variations can be made without departing from the spirit and scope of the present invention. It is self-evident to those with ordinary knowledge. Accordingly, such variations or modifications will fall within the scope of the claims of the present invention.
