L'Addition

L'Addition is a French tablet-based cash register editor for bars, restaurants, and foodservice establishments, built around the iPad. The suite covers in-table order taking on iPad Mini or iPhone, floor plan, kitchen routing, payment with the L'Addition Pay+ terminal, click-and-collect compatible with Uber Eats and Deliveroo, reservation management, and a reporting module to track activity. The editor also offers a purchasing service, L'Addition Purchases. No pricing is posted publicly: the site has an online quote builder where you declare your establishment type and desired services before being called back. The final cost combines a monthly software subscription per module and per terminal, the hardware, an installation service, and, if you take payments on L'Addition Pay+, a commission on each card transaction that is not published either.

L'Addition is certified by the LNE, the French national metrology and testing laboratory, under number LNE-34277, one of the two accredited bodies recognized in France, and covers the four requirements of French VAT anti-fraud law: immutability, security, retention, and archiving. That law binds any business selling at retail in France, and the certificate is downloadable from your client account; from outside France it carries no weight, and L'Addition sells almost exclusively to French establishments. The solution keeps ticket duplicates for six years and logs all actions in an audit trail. The product and support are entirely in French. Documented integrations include Zenchef and TheFork for reservation and Pennylane for accounting. APIs exist but the editor specifies they are open to technical partners and closed to the public: in-house development therefore requires going through the partner program. The non-public price remains the main gray area.
