# An invoice is corrected after delivery: clarifying which version to pay

Your customer receives an invoice, then a corrected document, followed by a reminder using the original amount. The obstacle may be an inconsistent instruction rather than unwillingness to pay. “Here is the correct version” leaves several questions unanswered. Does the new document replace the old one? Should a credit note be deducted? Has the payment already made been taken into account?

After a correction, the communication should allow the customer to reproduce the calculation. Identify the documents to use, explain the remaining balance and specify the action expected. This complements the accounting work and prevents individually accurate documents from combining into a contradictory request. It also gives the customer's accounts payable team something precise to verify.

## Classify the correction before drafting the message

First determine what changes: amount, quantity, tax, a party's identity, purchase order reference or presentation alone. A reduced service does not necessarily require the same treatment as an administrative clarification. Have the appropriate person validate the correction route, rather than improvising a new invoice simply to obtain a faster customer response.

The [French tax authority's guidance on corrective invoices](https://bofip.impots.gouv.fr/bofip/142-PGP.html/identifiant=BOI-TVA-DECLA-30-20-20-20-20220119) describes an explicit reference to the original document and, depending on the circumstances, a replacement invoice cancelling the previous one or a credit note. A replacement must identify the original invoice and expressly cancel it. That documentary relationship should remain visible in the customer message.

Do not silently replace a previously transmitted file and assume the recipient always checks the newest copy. They may already have entered the original into their approval process. [Preserving the case history when an invoice changes](https://www.billabex.com/en/blog/invoice-changed-after-reminder-versions/) protects the internal record; the explanation sent to the customer should make the current position immediately understandable. European businesses outside France should verify the correction rules applicable to their own invoices.

## Start from the balance after corrections and receipts

Consider an entirely simulated case. Invoice F-260 is for EUR 9,600 including VAT. Credit note A-074 for EUR 2,400 including VAT corrects a reduced service. The customer has already paid EUR 3,000, correctly identified and allocated. The remaining amount is EUR 4,200: 9,600 minus 2,400 minus 3,000.

| Case item                | Effect on the remaining amount |
| ------------------------ | -----------------------------: |
| Invoice F-260            |                     +EUR 9,600 |
| Credit note A-074        |                     −EUR 2,400 |
| Payment already received |                     −EUR 3,000 |
| Remaining balance        |                      EUR 4,200 |

The message should request neither the original EUR 9,600 nor the EUR 7,200 after the credit note, because EUR 3,000 has already been received. A useful explanation is: “Credit note A-074 for EUR 2,400 including VAT adjusts invoice F-260 for EUR 9,600 including VAT. After allocating your EUR 3,000 payment, the remaining balance is EUR 4,200.”

Explain what each number represents. A list of three amounts without signs or descriptions forces the recipient to guess. If the receipt is still being identified, say so and avoid presenting an unverified balance as confirmed. [Tracing an unallocated transfer](https://www.billabex.com/en/blog/payment-received-invoice-still-open-tracing-unallocated-cash/) should precede a request that might otherwise demand money already paid.

## Explain a replacement without combining two correction routes

Another approach, where appropriate and approved, may cancel and replace the original invoice with a new invoice for EUR 7,200 including VAT. This is an alternative to the EUR 2,400 partial credit-note route, rather than another step to add to the same calculation. After correctly carrying over the EUR 3,000 receipt, this route also produces a EUR 4,200 balance.

The message should identify which invoice replaces which, and where the earlier payment appears. Avoid attaching two invoices with only “please process the attached documents”. The customer might enter both, reject the new one as a duplicate or wait for a cancellation that has not been clearly identified.

[Odoo 18's credit-note documentation](https://raw.githubusercontent.com/odoo/documentation/18.0/content/applications/finance/accounting/customer_invoices/credit_notes.rst) distinguishes a draft credit-note route from a process that validates and reconciles a reversing credit note while opening a new draft invoice. This illustrates an operational point: a prepared document is not necessarily a validated document. Check the actual document status and payment allocations before using them in correspondence.

Do not confuse illustrative routes with the entries required in your own accounts. The accounting system and responsible professional determine the appropriate operations. The collections task is to communicate the approved result faithfully, without introducing a second reduction or losing the earlier payment during the transition between documents.

## Check the expected date independently of the filename

A newly generated PDF date does not, by itself, establish a new payment deadline. Review the agreed terms, the nature of the original error, the relevant delivery date and any subsequent agreement. Some situations require specific assessment; an automatic rule that every correction restarts the payment clock is too simplistic.

[Article 1193 of the French Civil Code](https://www.legifrance.gouv.fr/codes/article_lc/LEGIARTI000032041314) addresses contractual changes through mutual consent or causes authorised by law. It does not resolve every due-date dispute from the date on a file. If a new period is granted, have its scope confirmed and record the decision. If the deadline remains disputed, identify that uncertainty rather than concealing it.

Separate “corrected document sent on…” from “payment expected on…” in the message. A date for confirming receipt can also differ from the payment deadline. This prevents an administrative request from being interpreted as a commercial concession or an unsupported new demand. It gives the customer a clear basis for replying about the issue that actually remains unresolved.

## Deliver the correction into the right process

The contact who reported the error is not always the person entering the invoice. Identify the route used by the customer's accounting team: a dedicated address, a portal or another agreed channel. Send the valid documents and explanation to the appropriate contact, and request a targeted confirmation that the correction has been applied.

For example: “Could you confirm that credit note A-074 is linked to F-260 and that your records show the remaining EUR 4,200 balance?” This can reveal an entry mismatch. An automatic acknowledgement or technical delivery notification does not by itself confirm that the balance has been recorded correctly in the customer's system.

If an incorrect reminder has already been sent, acknowledge the difference directly: “Our previous message did not include the credit note. Please use the breakdown below.” The approach to [preparing a clear statement with several invoices](https://www.billabex.com/en/blog/multiple-invoices-due-dates-customer-statement/) helps preserve the same clarity when several documents need to be explained together.

## Check the next action after sending the explanation

Update prepared tasks, attachments and the amount used by automation. A correct manual reply is insufficient if the next reminder returns to the old invoice. Check internal summaries as well: “invoice corrected” should point to a particular document and explain its effect on the outstanding balance.

If the customer says it has initiated payment using the original amount, examine the bank position first. A correction may create an overpayment or a different supplementary amount from the one expected. Avoid requesting another full payment while that check is underway. Keep the announced transfer reference and identify who is responsible for reconciliation.

[Conversation tracking in Billabex](https://www.billabex.com/en/product/follow-ups-conversations/) helps retain the customer's explanations and previous decisions in the case context. During a demonstration, test a correction arriving after a reminder has been prepared and check what your team needs to approve. The outcome is straightforward to assess: the customer receives the right documents, understands their relationship and knows which amount actually remains to be handled.
