How much does Square cost in 2026?

Industry pricing guides put Square's 2026 rates at 2.6% + 10¢ per in-person transaction on the free plan, 3.5% + 15¢ for keyed-in payments, and online rates that rose to 3.3% + 30¢ in January 2026. The Plus plan ($49/month) lowers in-person rates slightly, and custom pricing is available for businesses processing over roughly $250,000 a year.

When should a business switch from Square to a custom POS?

When the total cost of flat-rate processing plus plan and add-on fees clearly exceeds what a custom system would cost over 2–3 years, or when your workflow no longer fits — you're running spreadsheets alongside the till, paying for multiple add-ons, or hitting features Square simply doesn't have. Volume alone isn't the trigger; friction plus volume is.

Does a custom POS eliminate card processing fees?

No — every card payment goes through a processor and interchange fees always apply. What changes is that a custom POS lets you choose your processor and negotiate interchange-plus rates at volume, instead of paying one bundled flat rate, and you stop paying monthly software and add-on fees per location.

Square vs Custom POS: When It's Time to Switch

We build custom POS systems for a living, so you'd expect us to tell you to ditch Square. We won't. Square earned its place on a million counters: you're taking payments the day the reader arrives, the software is genuinely polished, and there's no up-front build cost. If that describes your needs, stay — sincerely. This post is for the businesses where the maths and the workarounds have started to turn.

What Square actually costs in 2026

Square's pricing looks simple, and that simplicity is the product. According to 2026 industry pricing guides, the free plan charges around 2.6% + 10¢ per in-person transaction, 3.5% + 15¢ for keyed-in payments, and online rates that rose from 2.9% + 30¢ to 3.3% + 30¢ in January 2026. The Plus plan at $49/month trims the in-person rate slightly — analysis suggests you need to be processing tens of thousands a month before it pays for itself — and custom pricing only opens up beyond roughly $250,000 a year in processing.

Here's the honest part most comparison posts skip: no POS makes card fees disappear. Interchange — the cut the card networks and banks take — applies to everyone. What a flat rate does is bundle Square's software margin into every transaction. At low volume that bundle is a bargain. At high volume, you're paying a percentage of a much bigger number for the same software — and the difference between a flat rate and a negotiated interchange-plus rate becomes real money, every single month, forever.

Sign 1: the fee line has become a salary

Pull up a year of statements and add processing fees, plan fees, and every add-on (payroll, loyalty, marketing, team management are all separately priced). If the software-and-margin portion of that total rivals what a one-off build would cost — a basic custom POS runs roughly $8k–$12k, with our builds starting lower — you're no longer buying convenience, you're renting it at a premium. A custom system means you own the software, pay a processor of your choosing at rates you can negotiate, and stop paying per location.

Sign 2: you're running a second system next to the till

The spreadsheet for supplier orders. The notebook for trade accounts. The separate app for bookings that doesn't talk to checkout. Off-the-shelf POS covers the middle of the road well; the moment your business has a workflow of its own — wholesale pricing tiers, deposits, made-to-order production, job tracking — you start bolting things on around it. Each workaround is small. Together they're hours a week and errors you find at year-end.

Sign 3: the feature you need isn't coming

Square ships features for the average of its millions of users, which is exactly the right thing for Square to do — and no help if what you need is specific to you. If your growth plan depends on something the platform doesn't do and won't prioritise, you've hit the ceiling. A custom POS is built around your workflow instead of asking your workflow to fit the software, and it can fold in the automation and AI you'd otherwise buy as separate subscriptions.

When switching is the wrong move

Stay on Square if any of these are true: your monthly card volume is modest and fees are a rounding error; your operation genuinely fits the standard retail or café mould; or you don't have the appetite for a build project, even a small one. A custom system is an asset, but like any asset it needs someone to own it — we cover the honest numbers, including ongoing care, in our custom POS cost breakdown. Switching to save $80 a month is a bad trade. Switching to stop a four-figure monthly leak and unlock a workflow Square can't do is a good one.

What a switch actually looks like

It's less dramatic than it sounds. You keep trading on Square while the new system is built and tested alongside it — products, customers and sales history migrate across, staff learn it in quiet hours, and you cut over when it's boring. We start every project with a fixed-price audit (credited toward the build) that maps your real workflows first, and we'll tell you plainly if the audit says "stay on Square." That answer is genuinely on the table.

The bottom line

Square is the right answer until it isn't. The switch point isn't a revenue number — it's the month you notice the fees have become a salary, the workarounds have become a job, and the feature list has become a wall. If two of those three sound familiar, it's worth an hour to run the numbers properly.
