Software comparison
Best POS System for Small Business
A POS decision is really a payment-processing decision wearing a software costume. At real transaction volume, a 0.3-0.5 percentage point difference in card processing fees will cost or save you far more per year than the monthly software subscription will.
Updated October 8, 2026
Pricing reality
Processing rates and monthly fees both shift periodically, and contract terms (especially Toast's multi-year agreements) matter as much as the headline price. Confirm current rates and contract length directly before signing anything.

How we compare
The details that change the decision.
We focus on practical decisions: what the tool costs, what the free or entry plan really includes, where it fits, and which trade-offs are easy to miss. We cross-check vendor documentation and pricing information rather than repeating a feature list.
For a useful comparison, start with the job you need to complete, test the same workflow in each finalist, and check what happens when the free plan stops being enough. Then verify the current price and terms directly with the vendor before you commit.

Do this before paying
Run the same five-minute test on every finalist.
Feature lists are easy to compare and easy to overvalue. If the service offers a free plan or trial, use the same small real-world task in each finalist instead. Record what you can complete, where you hit a limit, and what requires an upgrade.

Detailed comparison
What to know before you choose.
01
Square
Best for Most small businesses starting out, especially without a long-term contract
Free option
Genuinely usable free plan - not a crippled trial.
Trade-off
No contracts, no early termination fees, and the cheapest hardware entry point here by a wide margin. Processing fees on the free plan are fine at low volume but get expensive fast - a shop doing meaningful monthly card volume should compare an interchange-plus processor once they outgrow "just starting out."
02
Toast
Best for Full-service restaurants specifically - not adapted for retail
Free option
Free Starter Kit available, tied to a multi-year agreement.
Trade-off
Built from the ground up for restaurant service - kitchen display routing, tip handling, and online ordering all feel purpose-made rather than bolted on. The trade-off is a real one: typical multi-year contracts with meaningful early termination penalties, unlike Square's month-to-month flexibility.
03
Clover
Best for Businesses that want to choose their own payment processor
Free option
Software-only free tier in some configurations, varies by reseller.
Trade-off
The open app marketplace and processor flexibility are genuine advantages over Square's more closed ecosystem. Pricing and terms vary meaningfully by which reseller/processor you go through - get quotes from more than one before committing.
04
Shopify POS
Best for Businesses selling both online and in person who want one inventory system
Free option
No free tier - requires a Shopify e-commerce subscription as a base.
Trade-off
If you already run a Shopify store, unifying online and in-store inventory into one system genuinely eliminates a real operational headache. You're paying for a Shopify subscription on top of the POS add-on, so it only makes sense if e-commerce is actually part of the business.
StackPick verdict
The bottom line.
Just starting out and want zero contract risk? Square. Running a full-service restaurant specifically? Toast's purpose-built workflows are worth the contract commitment. Want processor flexibility and an app marketplace? Clover, but shop multiple resellers first. Selling online and in person? Shopify POS avoids running two separate inventory systems.
