Invoicing
In every planCompliant invoices, sealed and followed until they are paid

NF203 numbering
The legal number is only assigned when you seal
A draft can be edited freely. When you finalize, ASAP assigns the definitive number, with no gap in the sequence, and seals the document: neither its content nor its number can change again.
- Before sealing, ASAP lists what is missing: nature of the operation, 0% VAT under the VAT exemption, expired quote
- Each point is fixed in one click, without leaving the invoice
- A sealed document is never edited: to correct it, you issue a credit note
Credit notes
A mistake? Issue a credit note, don't edit
The credit note starts from the original invoice and keeps the accounting chain readable. You pick a reason, and it appears on the PDF.
- Reasons: commercial gesture, billing error, goods return, cancellation, discount, other
- The detail is optional, except for “other”
- The credit note gets its own legal number
The whole cycle, from quote to payment

Frequently asked questions
Invoicing — what people ask us
What happens if I make a mistake after finalizing?
A sealed invoice can no longer be edited: you issue a credit note that cancels or corrects it, then, if needed, a new invoice.
Does ASAP handle deposits and credit notes?
Yes. You can issue deposit invoices, settle them, and create credit notes linked to an invoice while respecting the accounting chain.
How does Factur-X compliance work?
Every invoice is generated in the Factur-X format (PDF/A-3 with embedded XML) then validated by a dedicated engine before issuance, in the format expected by France's 2026 e-invoicing reform.
Can I customise my documents?
Yes: logo, colours, mentions, payment terms and reusable templates to move faster.
Invoicing is included in every plan, within each plan's limits: Starter caps e-invoice transmissions at 10 a month.
