We compared these POS systems using each vendor's pricing pages, documentation and feature lists, plus verified reviews on G2, Capterra and Trustpilot.
We also reviewed each vendor's Canadian docs for GST/HST support.
I haven't used most of these POS systems long-term myself, so the comparison is research-led.
Pricing is from May 2026. Check each vendor's page for today's rate.
01 POS processing rates โ what you actually pay per transaction
Processing fees are the most important cost in any POS system. A 0.5% difference on $500,000/year in sales is $2,500. Here are the real rates for each system.
๐จ๐ฆ Canadian POS note โ Helcim
Processing over $50,000 a year in Canada? Helcim offers interchange-plus pricing from 0.40% + 8ยข in person โ dramatically cheaper than Square or Shopify's flat rates.
It's Calgary-based, with full Interac support, no monthly fees and no contracts. Work out your break-even before defaulting to Square.
02 Square โ Best free POS for small business
Square is the default POS for most small businesses starting out โ and often the cheapest POS system for small business.
The software is free. You pay 2.6% + 15ยข per in-person transaction, with no monthly fee, and the free reader works with your phone or tablet right away.
It also covers an online store, invoicing, payroll, appointments and marketing, so you can skip juggling tools.
Available in the USA, Canada, Australia, the UK and Japan.
- Free POS software โ no monthly fee
- Free card reader included with signup
- Works with iPhone, iPad, Android
- Inventory, invoicing, and analytics all free

- Processing rates higher than interchange-plus at volume
- Account holds/freezes more common than bank processors
- Limited for complex restaurant table management

03 Shopify POS โ Best for selling online and in-person
Shopify POS is the strongest choice if you sell both online and in person.
Inventory syncs in real time. Sell an item in store and it's instantly removed from your online stock.
Staff can look up online orders, handle returns from any channel and see each customer's full purchase history.
The Shopify POS Go handheld gives staff a portable terminal for floor sales. It's the natural pick for Shopify merchants opening a physical store.
- Real-time inventory sync with Shopify online store
- Unified customer profiles across online + in-person
- Shopify POS Go โ portable handheld terminal
- Omnichannel returns (return in store, bought online)
- Canadian company โ full CAD + GST/HST support
- Staff management and permissions
- Requires a Shopify subscription ($39/mo+)
- Transaction fees if not using Shopify Payments
- Less suitable for restaurants (use Toast)
- Advanced POS features need Shopify POS Pro ($89/mo add-on)
04 Toast โ Best POS for restaurants
Toast is built for restaurants and food service.
Its Starter Package (from $0/month, pay-as-you-go) covers POS, payments and basic reporting with no monthly fee.
Paid plans add table management, kitchen display systems, online ordering, delivery, gift cards and staff scheduling. The hardware is built for kitchens and includes tableside tablets.
It's far more capable than Square for restaurants. The catch? You must use Toast Payments, with no option to switch.
- $0/month Starter Package for basic restaurant needs
- Kitchen Display System (KDS) integration
- Table management and floor plan builder
- Online ordering built in
- Restaurant-ruggedised hardware
- Staff scheduling and payroll add-on
- Must use Toast Payments โ cannot switch processors
- Hardware costs higher than Square
- US-focused โ limited Canadian availability
- Long-term contracts on some plans
05 Lightspeed โ Best for retail and best for Canada
Lightspeed is headquartered in Montreal and built for Canadian retail and hospitality from the ground up.
Its inventory tools are the most advanced here: purchase orders, vendor management, multi-location stock and automatic reorder points. It's a top retail POS system for small business.
In Canada, it processes Interac natively, handles GST/HST/PST/QST by province and bills in CAD.
Running a store with complex inventory? Lightspeed is the professional choice.

Clover has the widest range of hardware of any POS: Clover Go (phone dongle), Mini (countertop), Station (full terminal) and Kiosk (self-service).
Its App Market adds hundreds of third-party integrations for almost any need.
Clover is sold through banks and merchant providers, so rates are negotiable, unlike Square's fixed pricing.
It suits established businesses with specific hardware needs or leverage to negotiate rates.
- Widest hardware range โ from dongle to full kiosk
- Negotiable processing rates through merchant services
- Large App Market for customisation
