The Cost of a POS System for Small Business

A point-of-sale (POS) system is one of the few software purchases nearly every retail, food service, or in-person business makes, and the pricing structure is genuinely different from most business software — the real cost is rarely just a monthly subscription. Hardware, per-transaction processing fees, and software tiers all stack together, and comparing vendors on subscription price alone can be misleading. Two businesses paying the identical monthly software fee can end up with very different total costs once transaction volume and hardware choices are factored in.

Here's a practical breakdown of what Canadian small businesses actually pay for POS systems in 2026.

Free-to-Start Plans: The Cost Is in the Transaction Fees

Square's free POS software is a common entry point — no monthly software fee for the basic plan, with revenue instead coming from a per-transaction processing fee, typically in the range of 2.6%–2.9% plus a small fixed amount per tap or swipe in Canada. Shopify POS offers a similar structure through its Shopify Starter and basic plans, with transaction fees that vary depending on whether you're using Shopify Payments. For a low-volume business, "free" software with per-transaction fees is often the cheapest way to start — the fees only add up once sales volume grows substantially.

Basic Paid Plans: $30–$90 Per Month

Once a business needs more than the free tier — multiple staff logins, inventory tracking across more items, basic reporting — paid plans typically start around $30–$60/month for Square's higher tiers and Shopify's mid-tier retail plans, with Lightspeed Retail's entry plans commonly starting closer to $70–$90/month. Lightspeed is generally positioned toward retailers who need more robust inventory and purchase order management than Square's core product offers.

Mid-Tier and Multi-Location Plans: $100–$300+ Per Month

Businesses running multiple registers, multiple locations, or requiring more advanced inventory and staff management typically move into the $100–$300+/month range across Square, Lightspeed, and Shopify's higher plans. At this tier, negotiated processing rates also become more common — businesses with meaningful transaction volume can often negotiate lower per-transaction fees than the standard published rate.

Enterprise Retail Platforms: Custom Pricing

Lightspeed's enterprise tier and Shopify Plus serve larger multi-location retailers and typically involve custom pricing negotiated directly with the vendor, generally starting in the thousands of dollars per month once you include the software platform, negotiated payment processing, and any custom integrations. This tier is not the right starting point for a single-location small business.

The Most Common POS Mistake Small Businesses Make

The most common mistake is comparing POS vendors on the advertised monthly software fee alone and ignoring the processing rate, hardware cost, and contract terms — three factors that often matter more to the total bill than the subscription price. A business doing significant transaction volume can pay far more in processing fees over a year than in software fees, and a small difference in processing rate compounds quickly. Before choosing a POS system, calculate the total cost at your actual (or projected) transaction volume, not just the sticker price of the software plan.

Hardware is the other cost that catches new businesses off guard. A basic card reader can run as little as $50–$100, but a full countertop terminal with a receipt printer, cash drawer, and barcode scanner commonly runs several hundred to over a thousand dollars per station once fully equipped. Some vendors offer hardware bundles at a discount in exchange for a longer software contract — a reasonable trade for a business confident in its choice of platform, but worth reading carefully since early termination fees on these bundles can be steep.

Connecting Your POS to Your Phone and CRM

A POS system captures purchase history for every customer who buys in person — but many businesses also take phone orders, phone bookings, or phone inquiries that never touch the POS at all. Connecting your POS data with your CRM and phone system means a customer's purchase history is visible whether they walk in, call in, or book online, and it means a phone order can be entered directly into the same system tracking your in-store sales rather than living in a separate notebook or spreadsheet.

Verify current pricing and processing rates directly with any vendor you evaluate, as POS pricing structures and promotional hardware bundles change frequently.
