[Summary of Hot Issues on Fully Digitalized E-Invoices] What to do about duplicate bookkeeping of fully digitalized e-invoices? How to avoid it?

Published: 2025-01-20 17:05

As fully digitalized e-invoices become widespread nationwide, finance personnel face a series of new challenges. During the use of fully digitalized e-invoices, the issuer may red-letter reverse an invoice due to operational error, while the recipient may record and archive the same electronic invoice multiple times. How can these problems be effectively avoided? Let's learn about the "invoice posting identifier" function together~


I. What is an invoice posting identifier?

The E-invoice Service Platform provides invoice posting identification services for taxpayers. When taxpayers use this function, the system will simultaneously assign a posting status label to the invoice for finance personnel to check promptly and avoid duplicate reimbursement and posting. Taxpayers can use the "Invoice Posting Identification" module to perform posting identification operations on invoices obtained from the E-invoice Service Platform issued after January 1, 2022, helping taxpayers reduce the risk of duplicate posting and facilitating accounting management.

Taxpayers may through:

Click Electronic Tax Bureau - [Tax Digital Account] - [Invoice Business] - [Invoice Posting Identifier] module to perform invoice posting.

This function can effectively help taxpayers prevent the risk of the invoicing party mistakenly issuing red-letter invoices and the risk of the receiving party repeatedly recording and archiving electronic invoices.


II. What is the purpose of the invoice posting mark?

1. Avoid duplicate reimbursement and booking by the invoice recipient

Through the invoice booking identification function, the system can record the booking status of each invoice. Once an invoice is marked as booked, the system will automatically prompt when a subsequent reimbursement is attempted, effectively preventing duplicate reimbursement.

2. The invoice recipient can verify invoice status in batches

You can use the "Invoice Accounting Mark" function module and "List Import" (batch import). This function module will feed back various statuses of the invoices obtained: invoice has been voided; invoice has been red-letter reversed; whether the invoice is normal; whether the invoice can be selected for accounting, etc.

3. Prevent the invoicing party from mistakenly issuing red-letter invoices

The invoice posting mark function can confirm at the time of invoice posting. Once confirmed, the issuing party cannot arbitrarily void or reverse the invoice with a red-letter invoice without the consent of the receiving party, thereby protecting the rights and interests of the receiving party.


III. Which invoices can be marked for invoice booking?

Invoices issued after January 1, 2022, and not falling under the following circumstances, can be marked using the [Invoice Booking Identifier] function:

(1) Abnormal VAT deduction vouchers;

(2) Invoices that have been voided;

(3) Invoices previously recorded;

(4) Other.


IV. Is the invoice posting mark required?

For reimbursement, booking, and archiving of fully digitalized e-invoices, follow the relevant regulations of the finance and archive departments. The e-invoice service platform provides an invoice booking function, and you can mark the invoice booking identifier through the tax digital account of the e-invoice service platform. If you keep your own accounts in accordance with the Measures for the Administration of Accounting Archives, the Notice of the Ministry of Finance and the National Archives Administration on Standardizing the Reimbursement, Booking, and Archiving of Electronic Accounting Vouchers, and other relevant regulations, you may also keep your own accounts without marking the invoice booking identifier on the e-invoice service platform.
