Mandatory billing, SRS and WEB-SRM: the essentials for resellers

Who is covered by mandatory billing in Québec?

Two sectors fall under the mandatory billing measures: restaurants and remunerated passenger transportation. On the restaurant side, that covers restaurants, bars and catering businesses, plus people who habitually supply a good or a service in an establishment holding a bar permit. A client serving meals or drinks in one of those settings must therefore choose their till software from the certified SRS.

• Since 1 June 2025, a covered restaurant establishment transmits its transaction data through a certified SRS designed to communicate with the WEB-SRM, and hands every customer a bill produced by that same SRS.
• Since 1 January 2026, a covered taxi operator must use a second-generation certified SRS.
• Ministerial exemptions exist; they are dated and apply case by case. The merchant confirms them with Revenu Québec.

SRS or WEB-SRM: what is the difference?

The SRS is the merchant’s sales recording system, meaning the software that produces the bill. The WEB-SRM is the Revenu Québec cloud environment that software transmits its transactions to. For every transaction, the SRS sends the data and the WEB-SRM receives, validates, stores and answers it. Neither one is a device installed at the counter.

Revenu Québec lists three pieces of required equipment: a certified SRS, a printer compatible with the SRS where necessary, and an Internet connection. Without a reliable Internet link at the client’s site, nothing transmits, whatever hardware sits on the counter.

What role does hardware play in mandatory billing?

Revenu Québec authorises sales recording systems, meaning software, and publishes the list of those compatible with the WEB-SRM. Hardware comes in at execution time: it prints the required bill, shows the transaction and holds the connection. If the printer cannot produce a legible bill, the station is unusable, even with a certified SRS.

Who answers for what between the vendor, the merchant and the reseller?

The obligation belongs to the merchant: obtain the required equipment, transmit the prescribed information and hand a bill to every customer. The software vendor answers for its SRS and its certification. The reseller’s obligations are commercial: whatever goes into a written quote binds their business.

1. The merchant picks an SRS from the authorised products list and has it configured.
2. The SRS vendor states which printing interfaces and which models it supports.
3. The reseller supplies and installs hardware that matches that list, then proves it with a real test.
4. The wholesaler, G4POS, supplies the reseller and describes the hardware’s technical characteristics in the catalogue.

What should you check before going live?

Before you leave, print a complete bill from the client’s actual SRS, on the station that will be used. A bench test with demo software is not enough, because the layout, the QR code and the driver all differ.

1. Confirm with the client which SRS was chosen and which printing interface it expects.
2. Check that the site’s Internet link is in place and stable before the installation date.
3. Install the exact driver the software specifies.
4. Print a real bill and check that the QR code is sharp and complete.
5. Have that QR code scanned by a phone in front of the client, and record the result in the file.

What is G4POS’s role?

G4POS is a point-of-sale hardware wholesaler and sells mainly to resellers. The merchant chooses the SRS, the software vendor or its installer sets it up, and tax questions go to Revenu Québec or a tax professional. G4POS supplies the hardware and gives resellers the technical information about it.
