Get the VAT anti-fraud certification with Flectra

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 Flectra, 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 Flectra (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 Flectra

Getting compliant with Flectra 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.

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

To get the certification just follow the following steps:

  • Install the anti-fraud module fitting your Flectra environment from the Apps menu:

    • if you use Flectra Point of Sale: l10n_fr_pos_cert: France - VAT Anti-Fraud Certification for Point of Sale (CGI 286 I-3 bis)
    • in any other case: l10n_fr_certification: France - VAT Anti-Fraud Certification (CGI 286 I-3 bis)
  • 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.

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.


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 ‣ France.


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.


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 Flectra instance and must use it with due diligence. It is not permitted to modify the source code which guarantees the inalterability of data.

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