Description

Verification-free billing system and method for special electric power material tickets based on block chains

Technical Field

The disclosure relates to the technical field of electric power material management and control, in particular to a checking-free billing system and method for electric power material special tickets based on block chains.

Background

The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art.

The service hall of the power company supplier is mainly responsible for collecting material contract signing, settlement and related consultation service work, when the settlement of the arrived money is handled, a receipt acceptance bill and a special invoice for full value-added tax are required to be provided as payment bases, the four stages of settlement prepayment, settlement of the arrived money, settlement of delivery money and settlement of quality guarantee money are mainly included, and a guarantee bill, a receipt acceptance bill, a special invoice for full value-added tax, delivery bill and quality guarantee bill are required to be provided. The payment settlement process is mainly divided into three parts: (1) an intelligent material allocation platform-an electronic signature process of a receipt for receiving goods; (2) a special ticket intelligent settlement platform-a special ticket checking and authentication process; (3) settlement payment automation-payment automation process. After the electronic special ticket passes through the financial automatic verification, the ERP system automatically completes payment application creation and approval, and finally, settlement personnel complete automatic payment of goods and materials arrival payment and the ERP system checks accounts.

At present, a power company operates a special ticket intelligent settlement platform based on a provider online service hall, is externally connected with a national tax system, and internally interacts data with an ERP system through an isolation network gate. The supplier inputs the special ticket number on the network according to the purchase order, the platform can realize the remote check and automatic batch authentication of the special ticket, and the platform is transplanted to a new generation electronic commerce platform (ECP 2.0 for short) of the power grid company at present and is popularized and applied in the power grid company.

The inventor of the present disclosure finds that the existing invoicing process special for electric power materials has the following problems:

(1) the existing intelligent settlement platform for the special tickets can only upload paper special ticket images, namely, after a supplier needs to log in a service hall of the supplier on line to manually check the stored special ticket numbers of a national tax system, a purchase order number is input, the special ticket images are uploaded, and then the platform can establish the association between the special ticket images, the special ticket information of an electronic ledger bank of the national tax system and a purchase order of an ERP system and connect and store the electronic special ticket images to corresponding orders of the ERP system.

(2) The existing special ticket image can only be used for the verification and the image storage of the special ticket, and a supplier is still required to submit a paper special ticket as the basis for financial certificate manufacture, financial payment, archiving and auditing in the follow-up process.

(3) Because the ERP system (purchase order, receiving and warehousing information) of the electric power company and the billing system of the external supplier are communicated with each other at a breakpoint, accurate transmission and information sharing of the purchase order, the receiving and warehousing information cannot be realized, and therefore, the supplier cannot automatically and accurately make special tickets.

(4) The supplier can inquire and download contract and receiving information through ECP2.0 (a new generation electronic commerce platform of a power grid company), and can make special tickets according to the contract and the receiving information; the ERP purchase order and the receiving information can be manually inquired through systems such as a provider online service hall and the like, corresponding special tickets are issued, however, due to the fact that the supplier is subjective, the issuing content cannot be guaranteed to be 100% correct, even if the content of the special tickets is hundreds of correct, the issuing information of the special tickets cannot be guaranteed to be artificially tampered, and the like, namely, the special tickets are not credible, the issuing information of the special tickets such as material names, specification models, quantity of goods, units, sellers, tax numbers of the buyers, remark columns (order numbers or supply order numbers) and the like still needs to be manually and visually checked in advance, and if the issuing information of the provider is wrong or the issuing information is not standard, the ticket surface is not neat, the printing is not standard, the manual correction is carried out, the stain or the wrong-grid line pressing is carried out, and the like, the provider needs to be informed to re-standardize the issuing the special tickets.

(5) The existing special ticket checking method is to compare the special ticket information with the purchase order and the receiving and warehousing information corresponding to the contract and to check whether the information is consistent; the examination and verification details of the special ticket information are complicated, a large amount of labor and naked eyes are consumed for comparison, the special ticket information is qualified with a digital society, even if the automatic comparison and verification of a system is realized in the future, the comparison of the item lists of the same goods is only stopped in inaccurate comparison; for example, when the content of the specification model of a certain row of project in the contract is too much, the supplier generally only intercepts a continuous section of the specification model and makes the section in a special ticket; (if the specification model in the contract is 'AC 500KV universal, angle steel, Q420, conventional tower', only 'AC 500 KV' or 'angle steel, Q420' needs to be filled, but 'AC 500KV, Q420' or 'universal, conventional tower' needs not to be filled); the line items are more, the hall service personnel need to spend a large amount of time to compare the special ticket details line by line, and the error is easy to see the wrong line or check.
