Get the VAT anti-fraud certification with Odoo

As of January 1st 2018, a new anti-fraud legislation comes into effect in France and DOM-TOM. This new legislation stipulates certain criteria concerning the inalterability, security, storage and archiving of sales data. These legal requirements are implemented in Odoo, version 9 onward, through a module and a certificate of conformity to download.

Is my company required to use an anti-fraud software?

Your company is required to use an anti-fraud cash register software like Odoo (CGI art. 286, I. 3° bis) if:

  • You are taxable (not VAT exempt) in France or any DOM-TOM,

  • Some of your customers are private individuals (B2C).

This rule applies to any company size. Auto-entrepreneurs are exempted from VAT and therefore are not affected.

Get certified with Odoo

Getting compliant with Odoo is very easy.

Your company is requested by the tax administration to deliver a certificate of conformity testifying that your software complies with the anti-fraud legislation. This certificate is granted by Odoo SA to Odoo Enterprise users here. If you use Odoo Community, you should upgrade to Odoo Enterprise or contact your Odoo service provider.

In case of non-conformity, your company risks a fine of €7,500.

To get the certification just follow the following steps:

  • If you use Odoo Point of Sale, install the France - VAT Anti-Fraud Certification for Point of Sale (CGI 286 I-3 bis) module by going to Apps, removing the Apps filter, then searching for l10n_fr_pos_cert, and installing the module.

  • Make sure a country is set on your company, otherwise your entries won’t be encrypted for the inalterability check. To edit your company’s data, go to Settings ‣ Users & Companies ‣ Companies. Select a country from the list; Do not create a new country.

  • Download the mandatory certificate of conformity delivered by Odoo SA here.


  • To install the module in any system created before December 18th 2017, you should update the modules list. To do so, activate the developer mode. Then go to the Apps menu and press Update Modules List in the top-menu.

  • In case you run Odoo on-premise, you need to update your installation and restart your server beforehand.

  • If you have installed the initial version of the anti-fraud module (prior to December 18th 2017), you need to update it. The module’s name was France - Accounting - Certified CGI 286 I-3 bis. After an update of the modules list, search for the updated module in Apps, select it and click Upgrade. Finally, make sure the following module l10n_fr_sale_closing is installed.

Anti-fraud features

The anti-fraud module introduces the following features:

  • Inalterability: deactivation of all the ways to cancel or modify key data of POS orders, invoices and journal entries;

  • Security: chaining algorithm to verify the inalterability;

  • Storage: automatic sales closings with computation of both period and cumulative totals (daily, monthly, annually).


All the possible ways to cancel and modify key data of paid POS orders, confirmed invoices and journal entries are deactivated, if the company is located in France or in any DOM-TOM.


If you run a multi-companies environment, only the documents of such companies are impacted.


To ensure the inalterability, every order or journal entry is encrypted upon validation. This number (or hash) is calculated from the key data of the document as well as from the hash of the precedent documents.

The module introduces an interface to test the data inalterability. If any information is modified on a document after its validation, the test will fail. The algorithm recomputes all the hashes and compares them against the initial ones. In case of failure, the system points out the first corrupted document recorded in the system.

Users with Manager access rights can launch the inalterability check. For POS orders, go to Point of Sales ‣ Reporting ‣ French Statements. For invoices or journal entries, go to Invoicing/Accounting ‣ Reporting ‣ French Statements.


The system also processes automatic sales closings on a daily, monthly and annual basis. Such closings distinctly compute the sales total of the period as well as the cumulative grand totals from the very first sales entry recorded in the system.

Closings can be found in the French Statements menu of Point of Sale, Invoicing and Accounting apps.


  • Closings compute the totals for journal entries of sales journals (Journal Type = Sales).

  • For multi-companies environments, such closings are performed by company.

  • POS orders are posted as journal entries at the closing of the POS session. Closing a POS session can be done anytime. To prompt users to do it on a daily basis, the module prevents from resuming a session opened more than 24 hours ago. Such a session must be closed before selling again.

  • A period’s total is computed from all the journal entries posted after the previous closing of the same type, regardless of their posting date. If you record a new sales transaction for a period already closed, it will be counted in the very next closing.


For test & audit purposes such closings can be manually generated in the developer mode. Then go to Settings ‣ Technical ‣ Automation ‣ Scheduled Actions.


Do not uninstall the module! If you do so, the hashes will be reset and none of your past data will be longer guaranteed as being inalterable.

Users remain responsible for their Odoo instance and must use it with due diligence. It is not permitted to modify the source code which guarantees the inalterability of data.

Odoo absolves itself of all and any responsibility in case of changes in the module’s functions caused by 3rd party applications not certified by Odoo.
