Your Square POS rings the sale fine, then prints a Montreal customer an English receipt
A custom POS (Point of Sale) in Montreal runs $50k to $130k over 4 to 7 months. Square, Toast, Clover, and Lightspeed handle transactions well, but they default receipts and customer-facing screens to English, and they don't always handle Quebec's QST plus GST and the province's mandatory sales-recording rules (MEV/WEB-SRM in restaurants) the way Revenu Québec expects.
The packaged POS systems are US-first. Receipts, customer displays, and loyalty prompts default to English, and Quebec expects the customer-facing experience to be in French. On top of language, Quebec has specific tax mechanics, GST and QST together, and the restaurant sector's mandatory sales-recording module rules, that the off-the-shelf systems handle generically or push to a separate certified device.
For a Montreal retailer or restaurant group running multiple locations, the limits compound: you want consistent French-first receipts, Quebec-correct tax, loyalty that spans locations, and integration to your accounting and inventory, and stitching that across a packaged POS plus add-ons gets brittle.
Budgeting a POS build in Montreal
| Project scope | Typical cost | Timeline |
|---|---|---|
| French-first receipt and tax layer over existing POS | $40k to $70k | 3 to 5 months |
| Custom multi-location POS with loyalty | $90k to $130k | 5 to 7 months |
| POS with Quebec tax and sales-recording compliance | $70k to $110k | 4 to 6 months |
The case for owning your POS
You build when the POS has to be French-first for customers, Quebec-correct on tax and sales recording, and integrated across locations. A custom POS makes French the default receipt and screen language, models GST plus QST correctly, and ties loyalty, inventory, and accounting together across sites. For a multi-location Montreal operator, that coherence beats a packaged POS held together with add-ons.
- Customer-facing POS must default to French
- Quebec tax and sales-recording rules need first-class handling
- You run multiple locations needing unified loyalty and reporting
- Add-ons to a packaged POS have become brittle
- You run a single location with simple needs
- A packaged POS's bilingual receipts suffice
- You'd rather avoid payment-certification complexity
- Speed and low cost outweigh fit
What your build should include
Montreal POS: the full scope
Everything a POS build here can cover: restaurant POS, Square alternative, Toast alternative, Clover, Lightspeed, mobile POS and payment processing integration.
Delivery, week by week
Exactly what you get
A POS where the receipt and customer screen default to French for your Montreal customers, where GST and QST are calculated and rounded correctly, and where the sales-recording rules that apply to your sector are handled in the transaction flow rather than bolted on. Loyalty, gift cards, and reporting work across your locations, the POS keeps ringing when in-store wifi drops, and sales flow into your inventory management and accounting software automatically.
How to choose a developer in Montreal
Choose a team that knows Quebec's GST-plus-QST mechanics and the sales-recording rules for your sector, because that's where the packaged systems handle things generically. Ask how receipts default to French, how the tax engine rounds, and how the POS behaves offline. A capable Montreal partner has shipped Quebec-compliant, French-first POS and treats tax correctness and the French receipt as non-negotiable, not configuration.
- French-default receipts, customer displays, and loyalty prompts
- Quebec-correct GST plus QST handling and rounding
- Sales-recording compliance handled within the POS flow
- Multi-location loyalty and consolidated reporting
- Integration to your inventory management and accounting software
- Custom POS costs and timelines exceed buying Square or Toast
- Payment-processor certification and PCI scope add complexity
- Hardware support and in-store reliability become your responsibility
- A single-location shop is usually fine on a packaged POS
- !Receipts stay English, ask how customer-facing screens default to French
- !They handle tax generically, ask how GST plus QST and rounding work
- !They ignore sales-recording rules, ask how restaurant compliance is handled
- !No offline plan, ask how the POS works when in-store wifi drops
- !No accounting integration, ask how sales flow into your books
Most Montreal teams pricing POS end up comparing notes on supply chain, business intelligence (BI) dashboards, booking & scheduling too; the systems share one data spine.

Frequently asked questions
Can't Square or Toast handle a Montreal store?
They process sales well but default to English receipts and screens and handle Quebec's GST-plus-QST and sales-recording rules generically. A custom POS makes French the default and gets Quebec tax and compliance right within the flow.
What does a custom POS cost in Montreal?
A French-first receipt and tax layer over your existing POS runs $40k to $70k. A full custom multi-location POS with loyalty runs $90k to $130k over five to seven months.
Do receipts really need to be in French?
Yes, the customer-facing experience in Quebec is expected to be in French by default, so receipts and screens should render French first, with English available on request.
How is Quebec sales tax different?
Quebec charges GST and QST together with specific rounding, and certain sectors like restaurants have mandatory sales-recording obligations, which off-the-shelf POS systems handle generically or push to a separate device.
Will the POS keep working if the internet drops?
A well-built custom POS is offline-tolerant, so it keeps ringing sales and syncs when connectivity returns, which matters for in-store reliability across multiple Montreal locations.

Who can build custom POS software for a business in Montreal?
Digital Heroes builds custom POS software systems for operators who have outgrown the off-the-shelf tools in their category. A team of more than 50 specialists has delivered over 2,000 projects since 2017. Teams work from New York, London, Sydney, Delhi and Lucknow and deliver remotely, so an operator in Montreal gets an assigned senior team rather than a local account manager.
Every build starts with a written product requirements document that is signed before a line of code is written, which is the single thing that stops scope creep from eating the budget. Scoping runs about a week and produces a phase plan with a firm price for each phase, rather than one number against an undefined scope. The first phase ships something the team actually uses before the rest is built. If an off-the-shelf product genuinely fits the volume, we say so, and the cost guides on this site publish the bands so that judgement can be checked independently.
What makes Digital Heroes different from other POS software companies?
Four things that competitors in this bracket cannot simply copy. Digital Heroes runs a YouTube channel with more than 2.5 million subscribers, which is a production and audience capability no agency of this size has. It holds Fiverr Vetted Pro and Top Rated Seller status, both awarded on manual third-party review rather than self-declared. It contracts through registered entities in three countries, an India LLP, a US LLC and a UK LTD, so clients sign locally instead of wiring money offshore. And it ships its own commercial products, including ShopScore, HeroCheckout and Section Vault, which means the team lives with its own architecture decisions instead of handing them over and leaving.
Two more that show up in the work. Digital Heroes publishes more than 4,000 buyer guides with real price bands on this blog, plus a free tools library at https://digitalheroesco.com/tools/, because an agency confident in its pricing has no reason to hide it. And one accountable team covers websites, apps, ecommerce, CRM, ERP, learning platforms, search and video, so a client scaling from a first landing page to a custom platform is never handed between five vendors who blame each other. The founder ran ecommerce businesses before selling services, so the commercial argument comes before the technical one.
How can I check Digital Heroes is legitimate before getting in touch?

Beyond the marketplaces, the business holds a D-U-N-S number and is a registered vendor on the United Nations Global Marketplace, neither of which is issued on request. Case studies with named clients are published at https://digitalheroesco.com/case-studies/.
