Sent a Peppol invoice and spotted a mistake? A wrong amount, an incorrect VAT rate, a missing line item — it happens. Here's how to handle it properly.
⚠️ You cannot edit or "recall" a Peppol invoice once it has been sent. Peppol invoices are legally binding electronic documents. Once delivered to your client's access point, they can't be modified or retracted. The correct approach is to issue a credit note and, if needed, send a new corrected invoice.
Step 1 — Create a credit note for the original invoice
Go to Income in the app or web version.
Find the original invoice you want to correct.
Click on the invoice, then select "Edit".
Since the invoice was already marked as sent, Accountable will automatically ask if you'd like to generate a credit note linked to the original invoice — with the same amounts reversed (negative).
If only part of the invoice needs correcting (e.g. one line item was wrong), you can adjust the credit note amount before saving.
Step 2 — Send the credit note via Peppol
Once the credit note is saved, select "Save & prepare to send".
The credit note will be delivered to your client through Peppol, just like the original invoice was.
Your client receives it automatically on their Peppol access point.
Step 3 — Issue a new corrected invoice (if needed)
If the invoice wasn't meant to be fully cancelled — for example, only the VAT rate or an amount was wrong — you can now create a new invoice with the correct details and send it via Peppol as usual.
Common scenarios at a glance
Situation | What to do |
Wrong amount or VAT rate | Credit note the original → send a new invoice with the correct figures |
Wrong client details (name, VAT number) | Credit note the original → send a new invoice with updated details |
Duplicate invoice sent | Credit note the duplicate — no new invoice needed |
Forgot a discount or line item | Credit note the original → re-issue a corrected invoice |
What about your VAT return?
Accountable handles this automatically. Both the original invoice and the credit note are reflected in your VAT return. If the credit note falls in the same quarter, the amounts cancel out. If it falls in a later quarter, it will reduce your reported turnover in that period.
Good to know
Accountable automatically references the original invoice number on the credit note when you use the flow described above.
Send the credit note as soon as you discover the error — this keeps your records clean and avoids confusion for your client.
If both you and your client are on Peppol, the credit note is delivered electronically, just like any other invoice.

The availability of your team to help and guide people to understand their finances better is what really makes Accountable valuable. While the AI is able to give answers to most basic questions, specific scenarios need counsel from a human which your team performs beautifully.

They always answer for questions wherever is via direct e-mail or through app. If they can’t answer fully they will forward you to the right place. Documents were always prepared well and ready to send further to government. Everything is intuitive in the app and easy to sort out even for someone completely green in this field.
