How much does a POS system cost a small shop?

If you run one shop, the honest answer is: anywhere from nothing up front to several hundred dollars a month, and the pricing model matters more than the sticker. There are three ways small registers are sold today, and each moves your cost somewhere different.

1. Free software, paid per swipe

Square is the best-known example. The software costs nothing, and that is genuinely a good deal for a brand-new shop taking its first cards. The cost arrives on every transaction: in person, roughly 2.6% plus 10 cents a swipe. On $10,000 of card sales a month, that is about $270 a month — forever, and it rises with your sales. The register is also built around Square's own card processing, so if you ever want to shop for a better rate, you have to change your register too.

2. Hardware and a contract

Clover and similar systems are often sold through resellers: you buy or lease the terminal, and the deal is commonly tied to a processing contract that runs for years. The register itself can work out fine, but the total of equipment plus a locked-in processing rate is the most expensive path, and the hardest to leave.

3. Flat monthly software, your own terminal

The third model keeps the two apart: you pay a flat price for the register software, and you keep whatever card terminal and processor you already have — the register simply records how each sale was paid. This is how TradeBuilds Sales is priced: $29 a month per store, no contract, no cut of your sales. At $10,000 a month in card sales, the all-in cost is $29 plus whatever your existing processor charges, and you are free to renegotiate that rate at any time without touching your register.

The trade-off is the reverse of Square's: you pay a fixed cost even in a slow month, and you handle two relationships (register and card processor) instead of one. If your card volume is very low — a few hundred dollars a month — a per-swipe deal can genuinely be cheaper.

The costs people forget

Whichever model you pick, ask what happens when you need the things shops actually run on: layaways held for weeks, serialized stock, staff PINs, a profit report at tax time. On free tiers these are often paid add-ons or simply missing, which pushes owners back onto a spreadsheet and paper cards — hours of work every month that never shows up as a line item. Full retail suites built for large inventories run from around $69 to $89 a month, which is more than a one-location shop usually needs.

A practical rule of thumb for a one-location shop taking most of its sales on cards: add up what you paid in processing fees last month, add what you pay for the register, and compare that number against a flat fee plus your existing terminal. The comparison takes ten minutes and it is your money from there on.
