POS systems with no monthly fee
The short answer
A handful of POS systems charge $0/month for software. In 2026 they are 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. The vendor makes its money on processing instead, so the question that decides your total 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 ($1,299–$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. Processing is the expensive part, and it's where a 'free' system recovers its costs. Square gives you a 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 vendor gets paid from the hardware sale, not from a recurring fee or a locked rate.
Is a no-monthly-fee POS actually cheaper?
Over three years it can be, if it doesn't lock your processor. A $0-software, open system like JET costs $1,299 in hardware plus whatever processing you can negotiate. A $0-software but locked system like Square Free costs $899 for a Register plus a flat rate you can't shop, which at $20,000/month in sales is about $6,800/year you can't negotiate. The open system starts $400 higher, and you still need a card terminal from your processor, so it wins only if your negotiated rate saves more than that. The monthly fee was never the number to optimize.
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 does cost $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?
Up front, Square Free with a Register ($899), but its processing is locked. Over three years, a $0-software system you own outright with an open processor, like JET at $1,299 in hardware plus negotiable processing, can cost less at higher volume. What matters 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.
