Managing cash receipts is an essential component in the smooth running of your restaurant. Since 2018, regulations have required restaurateurs to use a compliant software or cash register system, in order to combat VAT fraud and guarantee fiscal transparency. But how do you choose the right certification for your cash register? There are two main options: NF525 and LNE certification. In this article, we explain why certification is essential, and compare the two standards to help you make the right choice.

Why choose a certified cash register?
Legal obligations and regulatory frameworkÂ
Did you know that since January 1, 2018, it has been mandatory to use a compliant cash register software or system to combat VAT fraud? This obligation is part of the 2016 Finance Act (article 88 of law no. 2015-1785) and requires merchants, like you, to use a solution that guarantees the inalterability, security, retention and archiving of cash register data.
The aim? To prevent the concealment of revenue and ensure total transparency vis-Ă -vis the tax authorities. To comply with the law, there are two major certifications available: NF525 and LNE. But which one should you choose for your establishment? Let's take a closer look.
Penalties and risks associated with uncertified cash registers
Failure to use a certified cash register can result in severe penalties. In the event of a tax audit, if your cash register system does not comply, you risk a fine of €7,500 per non-certified software or system, with an obligation to comply within 60 days.
In addition to the fines, lack of certification can lead to tax reassessments, and generate mistrust on the part of customers and partners. Certification is therefore a guarantee of safety and compliance, both for you and your customers.
