Till compliance and the certificate
Unalterability, security, retention, archiving: what the till guarantees, the extended integrity check you can rerun, the archive of a period, the FEC file and the certificate to print.
In this article
Unalterability, security, retention, archiving: the four obligations of article 286 I-3° bis of the French tax code are guaranteed by the till itself. You have no setting to turn on to be compliant — this page is here to prove it.


The check you can rerun in front of an inspector
Run it whenever you like: it recalculates the whole chain of your sales and closings, cross-checks the journal, recalculates every "Z" and flags a backdated document or a day with no closing — then reports "intact" or lists each break, one by one. This is the demonstration the tax authority can ask to see run live.
The archive of a period

Choose two dates and download the file: sales, closings and events for the period, with its fingerprint. This is what you hand over to an inspector or your accountant, and what you keep if you ever change software. The monthly archives, for their part, are produced on their own.
The file for an on-the-spot audit
An inspector who shows up in person asks for more than an archive: see Preparing a tax audit for the full file, adapted to your country's regime.
Printing the certificate

The compliance certificate is the first document the tax authority asks for in an audit. Print it, sign it, keep it with your accounting records: not being able to produce it costs a €7,500 fine.
Frequently asked questions
Do I need to turn on a setting to be compliant?
No. The four legal obligations are guaranteed by the till itself, with no setting to tick. This page only serves to prove it, to you as much as to an inspector.
What's the risk of not being able to produce the certificate?
Not being able to produce it during an audit costs a €7,500 fine. Print it and sign it in advance, don't improvise it on the day.
What's the integrity check for?
It recalculates the whole chain of your sales and closings, cross-checks the journal and flags backdated documents or days with no closing. This is the demonstration the tax authority can ask you to run in front of them.
What does the downloadable archive contain?
The sales, closings and events for the chosen period, with their fingerprint — your demo pieces are excluded from it. This is what you hand over to an inspector or your accountant, and what you keep if you ever change software.
An inspector asks me for a full file, not just an archive
Use Preparing a tax audit: it adds the FEC file, or your country's equivalent, and a note reminding you what your local law requires on top of Buiiild.

One or more till "Z" readings a day depending on your sessions, closings that chain themselves on their own, month after year, and the perpetual grand total.
