POS systems with no monthly fee
The short answer
A handful of POS systems charge $0/month for software. The real ones in 2026: JET POS ($0/month forever, software included with pay-once hardware, any processor), Square Free ($0/month but locked to Square processing), and Clover's payments-only tier ($0/month, very limited features). Toast advertises a $0 plan, but it carries a higher 3.09% + 15¢ processing rate and a 2-year contract.
"No monthly fee" never means free — it means the vendor makes its money on processing instead. The question that decides real cost is whether the $0 plan also locks your processor.
The genuine $0/month options
| System | Monthly software | The catch |
|---|---|---|
| JET POS | $0 forever | Pay once for hardware ($899–$1,800); software included; any processor — no lock-in |
| Square Free | $0 | Locked to Square Payments at 2.6% + 15¢; advanced features need paid plans |
| Clover (payments-only) | $0 | Very limited features; device locked to one processor; reseller contracts common |
| Toast Starter Kit | $0 | Higher 3.09% + 15¢ rate and a 2-year agreement — not truly free |
What '$0/month' is really paying for
Software is the cheapest part of a POS. The expensive part — processing — is where a 'free' system recovers its costs. Square gives you a genuinely capable free plan and makes its margin on a flat, locked rate. Toast's free tier raises the processing rate to compensate. The only model where $0/month and processing freedom coexist is a pay-once system you own, where the hardware sale (not a recurring fee or a locked rate) is how the vendor gets paid.
Is a no-monthly-fee POS actually cheaper?
Over three years, yes — if it doesn't lock your processor. A $0-software, open system at $899 hardware costs $899 plus whatever processing you can negotiate. A $0-software but locked system costs the same hardware plus a flat rate you can't shop — which at $20,000/month in sales is about $6,800/year you have no leverage over. The monthly fee was never the thing to optimise.
Frequently asked questions
Which POS systems have no monthly fee?
JET POS ($0/month forever, software included with pay-once hardware, any processor), Square Free ($0 but locked to Square processing), and Clover's payments-only tier ($0 with very limited features). Toast's $0 Starter Kit charges a higher 3.09% + 15¢ rate plus a 2-year contract.
Is a free POS system really free?
No — 'free' means $0 software, not $0 cost. The vendor earns on payment processing instead. A free plan locked to one processor at a flat rate can cost far more over time than a paid plan with negotiable processing.
Is Square really free?
Square's Free plan genuinely costs $0/month and is very capable. The trade-off is that it's locked to Square Payments at 2.6% + 15¢, which you can't negotiate at small volume, and some advanced features require the $49 or $149 plans.
What's the cheapest POS over three years?
A $0-software system you own outright with an open processor — around $899 in hardware plus negotiable processing. The key is processor freedom: $0/month plus a locked flat rate is often more expensive than a small monthly fee with a negotiated rate.
Does no monthly fee mean no contract?
Not necessarily. Toast's $0 Starter Kit still has a 2-year agreement, and some $0 Clover setups run through resellers with multi-year contracts. Always check the contract term separately from the monthly fee.
