If your restaurant is in the Quebec province, you will need a Sales Recording Module
Also known as MEV for Module d’Enregistrement des Ventes
What’s an SRM?
The Sales Recording Module is a device connected to your Point-Of-Sale that records every sale made and transmits the necessary information to Revenue Quebec while the printed receipt that contains a unique barcode certifies accuracy and retention of business records. In Quebec, it is mandatory to use it for any type of restaurant, catering service, or bar.
