There is no best POS system. There is the one that fits how you sell.

I resell payment equipment for a living. I sell Clover, Square, Valor, PAX and Dejavoo, and I earn money when you buy one. I do not sell Toast and earn nothing if you pick it. Toast is here anyway, because leaving it out of an honest roundup would be dishonest.

Read it accordingly. Where I say a system fits you, go and check. Where I say one is wrong for you, that line is worth more — a seller talking you out of four of his own five products is telling you something. There is no ranked list here, because the answer depends on the business.

One rule governs the page: processor and POS pricing changes, so treat every figure here as a snapshot and confirm current rates with the provider before you sign. Square raised its online rate in January 2026. Valor, PAX and Toast carry no prices here on purpose — those are quoted by a reseller or the vendor.

Clover suits the business whose register has to run the business, not just capture the card: inventory, staff, an app market, hardware from a pocket reader to a dual-screen station. It is owned by Fiserv and sold through thousands of banks and resellers, so the identical Station can cost two businesses very different amounts. Published 2026 card-present rates run roughly 2.3% to 2.6% plus 10 cents, keyed and online around 3.5% plus 10 cents, and the plan is billed per device.

Square suits the business that wants to be selling this afternoon: the cleanest software of the five to learn, hardware off a shelf. Published 2026 free-plan rates are 2.6% plus 15 cents in store, 3.3% plus 30 cents online or by invoice, 3.5% plus 15 cents keyed. Paid plans buy a lower counter rate — Plus about $49 a month at 2.5% plus 15 cents, Premium about $149 a month at 2.4% plus 15 cents — with online at 2.9% plus 30 cents.

Valor and PAX are the answer when the payment is the job and the POS work is light. Both make Android smart terminals, compact through dual-screen, and Valor is engineered around dual-pricing and surcharge programs, with a virtual terminal and invoicing included. Neither has a public sticker price: the plan and the rate are set by whoever sells it.

Toast is the one I do not sell, and it is a restaurant platform rather than a general one: hardware built for heat and spills, handhelds, kitchen screens and ordering from a single vendor. The structural difference is that Toast is generally sold as a bundle, with the software and the card processing from the same company. Confirm that with Toast: it decides whether you can shop your rate later.

A POS bill has two halves: a rate on every sale and a software plan every month. Owners shop the plan because it is one visible number, and the rate is almost always larger. It has no ceiling, so it grows as fast as you do — at $5,000 a month the gap between structures is small change, at $40,000 or $80,000 it is real money.

Then the layer nobody quotes. Clover's per-device 2026 plans run from about $14.95 a month for Essentials, through about $49.95 for Register and about $54.95 for Counter Service Restaurant, to about $84.95 for Table Service Restaurant — and per device means two stations generally means paying twice. A bank or reseller can also add a statement fee, a PCI fee, a gateway fee and sometimes a lease. Those agreements often run 36 to 48 months with early-termination fees of $500 or more; buying direct typically keeps you month-to-month.

The only fair comparison is your effective rate: total fees divided by total sales, every add-on counted. Work it out from a real statement before you talk to anybody, including me. It also exposes what flat-rate pricing costs, since the same percentage is charged on every card — pay with cheap debit and the saving stays with the processor.

Start with how you sell. Count the places a customer can pay you, then ask what the register must do that a card terminal cannot. If the honest answer is not much, you want a smart terminal. If it involves inventory, staff permissions, tables or a kitchen, you want a full POS.

Then judge the deal separately from the device. The same Clover hardware can arrive month-to-month at published rates or on a four-year lease with a termination clause, and the box looks identical either way. Read the term, the termination clause and every recurring fee first.

Last, price the switch. Somebody retypes your item list, staff relearn a screen mid-rush, and your reporting history stays behind. That is why the right answer for many businesses is to keep the hardware and fix the agreement.
