Description

Technical Field

[0001] The present invention belongs to the field of management, and specifically relates to a commodity procurement audit system, equipment and medium based on blockchain technology. Background Art

[0002] Auditing is an independent economic supervision activity carried out by specialized institutions and personnel authorized or commissioned by the state to review and supervise the authenticity, correctness, compliance, legality and effectiveness of the audited unit's finances, financial revenues and expenditures, business management activities and related information in accordance with national laws and regulations, auditing standards and accounting theories, using specialized methods, evaluate economic responsibilities, authenticate economic transactions, and maintain financial laws and regulations, improve business management, and enhance economic efficiency.

[0003] For enterprises or organizations, there are usually various procurement needs due to the needs of production, sales and other activities. However, during the procurement process, due to imperfect systems or neglect of auditing, some people often use procurement to embezzle the property of the enterprise or organization, increasing the cost of the enterprise, and those who embezzle the property will not receive the legal sanctions they deserve.

[0004] Property misappropriation during the procurement process includes at least the following situations:

[0005] 1. The purchasing staff over-reported the purchasing demand or over-reported the purchasing price, and the actual purchasing price was less than the purchasing price paid, and the difference was pocketed;

[0006] 2. The purchaser and the seller collude to sell to the purchaser at a price that greatly exceeds the market price, and the two parties divide the excess price;

[0007] Third, the purchaser and the seller collude to sell inferior products to the purchaser, and the difference between the product to be purchased and the inferior product will be pocketed. More seriously, the products purchased by the purchaser may have a negative impact on the company when used. For example, if a batch of raw materials is purchased for the production of important products of the company, due to procurement problems, the company's large investment funds will face huge losses.

[0008] Fourth, only purchase information is recorded during procurement, which is difficult to verify during audit. Summary of the invention

[0009] In view of the above-mentioned deficiencies, the present invention provides a commodity procurement audit system based on blockchain technology to audit the procurement of enterprises or organizations, reduce cost waste of enterprises or organizations, and improve the utilization rate of enterprise funds.

[0010] The present invention is achieved through the following technical solutions:

[0012] Preferably, the system further comprises a fourth acquisition module, which collects logistics information of the goods from the seller to the buyer and uploads the logistics information to the blockchain.

[0013] Preferably, the buyer's transaction information includes at least one of the following: transfer account, transfer voucher, transfer amount, identity information of the person in charge of purchase, and sales contract.

[0014] Preferably, the buyer's commodity usage information includes at least one of the following: user, using department, remaining inventory, usage purpose, commodity photos or videos.

[0015] Preferably, the transaction information of the seller includes at least one of the following: seller's company name, seller's company address, seller's platform channel, seller's payment account, and seller's person in charge information.

[0016] Preferably, the logistics information includes at least one of the following: place of shipment, place of receipt, sender, consignee, name of goods, quantity of goods, name of logistics company, freight, consignee information, and logistics bill.

[0017] Preferably, the method for processing system audits includes conducting a preliminary audit on the buyer's purchase of goods to verify the rationality of the purchase of goods. The preliminary audit is: uploading the information of the person in charge of procurement to the blockchain and verifying it. The information includes the identity of the person in charge of procurement, the department that proposed the procurement demand, and the procurement history record. Based on the information of the person in charge of procurement, verify whether the goods that the person in charge of procurement needs to purchase match the information of the person in charge of procurement.

[0018] Preferably, the method for processing system audits includes conducting a usage audit on the buyer when using the goods to verify whether the goods are reasonably used to generate benefits. The usage audit is as follows: during the use of the goods, the distribution of the goods is uploaded to the blockchain to verify whether the distribution of the goods is reasonable. After the goods are distributed to each department, each department records the main uses and benefits of the goods during use to ensure that the goods are reasonably used.

[0019] A device for managing commodity procurement information includes at least one processor and a memory communicatively connected to the at least one processor; wherein the memory stores instructions executable by the at least one processor, and the instructions are executed by the at least one processor so that the at least one processor can: collect transaction information of buyers and upload the transaction information of buyers to a blockchain; collect commodity usage information of buyers and upload the commodity usage information of buyers to a blockchain; collect transaction information of sellers and commodity information of sellers, and upload the transaction information of sellers and commodity information of sellers to a blockchain; process and audit the transaction information of buyers, commodity usage information, transaction information of sellers and commodity information of sellers, and upload the audit results to a blockchain.

[0025] In order to make the purpose, technical solutions and advantages of this specification more clear, the technical solutions of this application will be clearly and completely described below in combination with the specific embodiments of this specification and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in the specification, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0027] like Figure 1 A commodity procurement audit system based on blockchain technology (hereinafter referred to as the system) shown includes a first acquisition module 1, a second acquisition module 2, a third acquisition module 3 and a processing module 5, wherein the first acquisition module 1 is used to collect the buyer's transaction information and upload the buyer's transaction information to the blockchain; the second acquisition module 2 is used to collect the buyer's commodity usage information and upload the buyer's commodity usage information to the blockchain; the third acquisition module 3 is used to collect the seller's transaction information and the seller's commodity information, and upload the seller's transaction information and the seller's commodity information to the blockchain; the processing module 5 processes and audits the buyer's transaction information, the commodity usage information, the seller's transaction information and the seller's commodity information, and uploads the audit results to the blockchain; the audit content of the processing module 5 includes: whether the buyer's procurement demand is reasonable, whether the buyer's transaction information matches the seller's transaction information; whether the destination of the commodity is normal during the use of the commodity, whether the commodity is used reasonably; the quality and value of the commodity and the credit status of the seller.

[0028] The system collects the buyer's transaction information and the buyer's commodity usage information, and can clearly understand the circulation of the purchased goods after entering the enterprise or organization, and the ownership of each part. For example, the purchasing manager purchases a total number of goods, part of which is used within the enterprise or organization, part of which is used for customers, and part of which is not used and stored in the warehouse, or there are other purposes. The total number of purchased goods and the number of goods used for each purpose are recorded in the blockchain to prevent tampering, and are convenient for users (such as auditors) to view, which can prevent the purchased goods from being embezzled or misappropriated, and can also prevent over-reporting of purchasing needs but not using them to misappropriate them.

[0029] The quantity of purchased goods is provided by the person in charge of purchase, including the purchase quantity and supporting documents. The enterprise or organization will have an approval process for the purchase behavior, and the leader who signs and is responsible for the endorsement within the enterprise will endorse it. Therefore, we believe that the total quantity of purchased goods is credible; the use of the goods after purchase is provided by the user, including the actual number of claims for each use channel and the specific matters of the application of the goods. In order to prevent empty purchases during the purchase process (empty purchases refer to the phenomenon that the purchaser does not actually purchase anything, but colluded with the seller and the user to embezzle the price), the user retains photos or videos of the use process and the arrival of the goods at the company as proof of product information or transaction information.

[0030] The system collects the buyer's transaction information, the seller's transaction information and the seller's product information, and can clearly know whether the buyer's payment is consistent with the seller's receipt, and can clearly know the quantity, specifications, channels, unit prices, brands, and manufacturers of the products provided by the seller, and can use this to determine whether the price paid by the buyer is at a premium relative to the market price. The buyer's transaction information, the seller's transaction information and the seller's product information are all recorded in the blockchain to prevent tampering, and are convenient for users (such as auditors) to view, which can prevent the buyer's reported purchase quantity from being inconsistent with the seller's actual sales quantity, and can prevent corporate or organizational procurement personnel from purchasing inferior goods and making profits from them.

[0031] The buyer's payment can be proved by the transfer account and transfer voucher, and the seller's payment and the authenticity of its goods can be proved by the seller's company name, seller platform channel, seller's payment account, product name, etc. If the price paid by the buyer is actually received by the seller, that is, the amount of money paid by the buyer is consistent with the amount of money received by the seller, then the transaction is normal, and it is only necessary to inspect whether the value of the goods matches the money paid by the buyer, including whether the quantity of goods is consistent, whether the price of the goods is inflated, and whether the quality of the goods is qualified. The quantity inspection method of goods has been described above. According to the quantity, specifications, channels, unit prices, brands, manufacturers, etc. of the goods, the actual price of the goods at the time of purchase can be inferred. Whether the price of the goods is inflated can be judged by collecting the name of the goods, the price of the goods, the quantity of the goods, the specifications of the goods, the quality of the goods, the manufacturer of the goods, the name of the seller's company, the address of the seller's company, the channel of the seller's platform, the seller's payment account, and the information of the seller's person in charge to determine whether the price of the goods is appropriate. For example, determine through which channel the seller sells, whether it is a physical store or an online mall, and what platform the online mall chooses, and find the same goods by comparing the product information to inquire or check the price. Whether the quality of the goods is qualified is determined by the product information. After determining the product name and manufacturer, you can check the product's registration with the relevant regulatory authorities and the quality certification the product has passed. By checking the product's certification qualifications and the manufacturer's qualifications, you can determine whether the quality of the goods is qualified.

[0032] By auditing whether the purchased goods are qualified, the purchaser is encouraged to purchase better quality goods for use, such as purchasing raw materials for production, purchasing testing equipment for quality inspection, and purchasing gifts for public relations or employee benefits. More funds can be used in the enterprise more efficiently, which has a far-reaching impact on the development of the enterprise.

[0033] The method for processing system audit includes conducting a preliminary audit when the buyer purchases goods to verify the rationality of the goods purchase. The preliminary audit is: uploading the information of the person in charge of purchase to the blockchain and verifying it. The information includes the identity of the person in charge of purchase, the department that proposed the purchase demand, and the purchase history record. According to the information of the person in charge of purchase, verify whether the goods that the person in charge of purchase needs to purchase match the information of the person in charge of purchase. The information of the purchasing department, the person in charge of purchase, and the purchase records can be uploaded to the blockchain. When the person in charge of purchase submits the purchase demand, the processing module audits the purchase demand. The department or individual that proposes the purchase demand needs to be related to the activities that the department or individual is responsible for. For example, the department responsible for sales will not have a purchase demand for purchasing raw materials for production. The types of goods purchased and the goods requested to be purchased by each department or individual can be determined according to the actual situation of each enterprise. If there is a purchase phenomenon outside the normal situation, such as the purchased goods are inconsistent with the scope of departmental responsibilities, the goods purchased by the person in charge of purchase are different from the types of goods purchased in the purchase person in charge's history record, etc., it is necessary to make a record and identify it, and the purchasing department or the person in charge of purchase needs to submit a certificate and explain the reason, and upload it to the blockchain.

[0034] The method for processing system audit includes conducting a use audit on the buyer when using the goods to verify whether the goods are reasonably used to generate income. The use audit is as follows: the distribution of goods is uploaded to the blockchain during the use of the goods to verify whether the distribution of goods is reasonable. After the goods are distributed to each department, each department records the main purpose and income of the goods during use to ensure that the goods are reasonably used. The goods purchased by the enterprise need to mark their flow direction and record their flow direction in the blockchain. The flow direction of the goods is uploaded to the blockchain once by the person responsible for managing all goods (such as warehouse personnel), and the person who comes to collect the goods is uploaded to the blockchain each time. The use process of the goods is recorded and uploaded to the blockchain. The flow direction of the goods is recorded and will not be tampered with, ensuring that the flow direction of the goods is reasonable. In this process, the flow information of the goods also needs to be uploaded to the blockchain and audited to prevent resource abuse. For example, gift goods purchased by the sales department and sent to customers will not flow to the production department on a large scale. After the goods flow to each department, each department uploads the specific application of the goods and the benefits generated after use to the blockchain. For example, the production department uses the purchased raw materials for production, how many products are produced, and what is the qualified rate, so as to calculate the product cost and the impact of the purchased raw materials on the qualified rate of the product; for example, the gifts purchased by the sales department are used for customer relationship maintenance, and how much sales have increased. The processing module processes the data in the blockchain and obtains the contribution of the purchased goods to the benefits of the enterprise. If the effect is good, it can be recorded as a case. If the effect is not good, lessons should be learned. The audit of procurement can help enterprises make the economic costs generated by procurement produce greater economic benefits, help enterprises reduce costs and increase profits.

[0035] Figure 1 The module division scheme in the architecture is exemplary, not the only scheme. For example, at least two of the first acquisition module 1, the second acquisition module 2, and the third acquisition module 3 can also be integrated into the same data acquisition module. From a program perspective, these modules are software modules. Of course, since the system also needs corresponding hardware to carry it, these software modules also have corresponding hardware modules to support them. These hardware modules can be located on multiple different devices, such as different blockchain node devices.

[0036] like Figure 2 As shown, Figure 2 exist Figure 1 On the basis of , a fourth collection module 4 is added, and the fourth collection module collects the logistics information of the goods from the seller to the buyer. The logistics information includes at least one of the following: the place of shipment, the place of receipt, the sender, the consignee, the name of the goods, the quantity of the goods, the name of the logistics company, the freight, the consignee information, and the logistics order. The channels for the purchased goods to be sent to the buyer include: logistics companies, self-pickup by the buyer, and door-to-door delivery by the seller. When the buyer receives the goods, the above-mentioned logistics information must be uploaded to the chain as proof of delivery of the goods. The logistics information can be provided by the recipient, or it can be provided separately by the recipient and the logistics company by agreement. A preferred implementation method is that the agreement reached with the logistics company is about

[0037] The information of the goods is provided by the buyer and the seller, the use of the goods is provided by the person in charge of each usage channel, the logistics information of the goods is provided by the logistics party and the recipient, and the information of all parties of the goods is recorded by multiple parties and uploaded to the blockchain. It cannot be tampered with, and the authenticity of the data is guaranteed, which is convenient for users (such as auditors) to use.
