Since 1 January 2018, a new law applies to the use of a management software. For the cash register (Paymash), it is mandatory that the conditions of immutability, security, storage and archiving of data are met. For this, a certificate must be provided by the manufacturer, either by an accredited body or by an individual certificate issued by the issuer.

This is an obligation for all natural persons and legal entities under private or public law that are subject to VAT.

In order to be compliant with the law, we have worked determinedly to offer such a certificate. The certificate is provided by the application "Paymash POS - POS system", which is available in the App Store and Google Play Store (The blue application with the "P").


Why did Paymash opt for individual certification?

As described in this article, Paymash meets the requirements of the tax authorities and goes beyond them in many respects. For example, Paymash is also compliant with fiscal obligations in other European countries such as Austria or Germany. Paymash has opted for individual certification.

As is often the case when a law wants to regulate a market, there are companies that want to profit from it. In France, this is mainly the case with private companies such as INFOCERT with its NF525 standard or state bodies such as the Laboratoire National d'Essais.

The use of these bodies is obligatory by law when distributors develop their own POS software. This is especially true for large distributors who want to control their sales process from start to finish. In the case of a retailer that relies on an independent POS manufacturer such as Paymash, the use of a third-party certifier is optional.

Paymash did not want to use these organisations because the specifications they offer are too rigid and slow us down in innovation.


Conditions of data immutability

When corrections are made to transactions, whether by the software or system itself or by a device outside the software or system, such corrections (changes or cancellations) must be made by separate transactions and not by direct changes to the original recorded data.

In other words, the state requires that it should not be possible to edit a transaction that has already been closed. This requirement is clearly intended to prohibit software that would allow receipts to be deleted at the end of the day.

Paymash implemented this principle long before it became a legal requirement.


Retention terms

The accounting or management software or POS system that records the accounting data must provide for a closing. This closure must be at the end of at least one annual period (or by financial year if the financial year is not based on the calendar year).

Paymash allows daily, monthly and annual closing of accounts and calculates cumulative and summary data that is integral and immutable to your accounting.


Archiving terms

The purpose of archiving is to freeze the data and give a specific date to the archived documents. It must provide a technical mechanism to ensure the integrity of the archives created over time and their consistency with the original accounting data from which they were created.

All data recorded in Paymash is first stored on the tablet/smartphone before being transferred to our secure servers. A powerful backup system ensures that your data is archived and replicated to meet archiving requirements.
