Running a small shop in Canada means dealing with sales tax that changes by province. A store in Ontario charges HST, a store in British Columbia charges GST plus PST, and a store in Alberta charges GST alone. Your POS has to get that right on every receipt, while still being simple enough to run from the counter or the shop floor.
This guide covers what Canadian small retailers should look for in retail POS software in 2026, with a checklist and answers to common questions.
Sales Tax in Canada: What Your POS Must Handle
Canadian sales tax has three building blocks, and your POS needs to apply the right combination for your province:
- GST (Goods and Services Tax): The 5% federal tax charged across Canada. In Alberta and the territories it is the only sales tax.
- HST (Harmonized Sales Tax): GST and provincial tax combined into one rate, used in Ontario (13%) and the Atlantic provinces.
- PST, RST or QST: A separate provincial tax charged alongside GST in British Columbia, Saskatchewan, Manitoba and Quebec.
Rates and rules change, so always confirm current rates with the Canada Revenue Agency or your provincial tax authority, and check with your accountant before going live.
Key Features to Look For in a Canadian Retail POS
1. Configurable Tax Components
Set up the tax for your province, whether that is GST alone, a single HST rate, or GST plus PST, and show each tax clearly on every receipt. RetaPOS supports multiple tax rates on a single bill.
2. Tax Reports for Filing
Pull tax summary reports by period so you or your accountant can prepare GST/HST returns without rebuilding totals from receipts.
3. Inventory Built for Small Shops
Track stock for up to 500 SKUs with barcode scanning, low-stock alerts and supplier purchase orders — the scale most independent Canadian retailers actually operate at.
4. Customer Loyalty and Messaging
Award loyalty points, send birthday offers and keep customers coming back with WhatsApp or SMS messages, instead of competing with big-box stores on price alone.
5. Mobile-First Billing
Ring up sales on any Android or iOS smartphone, so you do not need expensive dedicated terminals to start. RetaPOS is cloud-based and needs a stable Wi-Fi or 4G/5G connection.
