Choosing a POS system is one of those decisions that looks small until you get it wrong. The register is where every sale, every inventory count, every customer record, and every fee actually happens, and switching later means retraining staff, migrating data, and often buying hardware twice. The good news is that for most small businesses the shortlist is genuinely short: Square, Clover, or Toast. The better news is that they are different enough that once you know what you sell and where you sell it, the answer mostly picks itself. Here is the honest version of that comparison, including the fee math the sales pages bury.

TL;DR
Square wins for most small businesses because you can start free, the hardware is cheap, and everything from invoicing to online ordering lives in one ecosystem. Clover wins when you want dedicated countertop hardware, work with a bank or processor that bundles it, or run a franchise that standardizes on it, but watch the third-party reseller contracts. Toast wins for restaurants without a serious fight: kitchen display screens, menu management, tips, and staff scheduling are built for food service in a way the other two only approximate. Retail shops should also weigh inventory depth, which we cover in our guide to inventory management software for small retail.
What Actually Matters in a POS System
POS marketing loves feature lists, but four things determine whether you will be happy in a year. First, total cost of ownership: the monthly software fee is usually the smallest number involved. Processing fees on every card tap are where the real money goes, and a difference of a few tenths of a percent compounds fast at volume. Second, hardware lock-in: Square hardware runs Square, Clover hardware runs Clover, and Toast hardware runs Toast. Nobody’s terminal becomes useful if you switch, so the hardware bill is really a commitment ceremony. Third, ecosystem fit: your POS should talk to your accounting software, your online store, and your payroll without duct tape. Fourth, contract terms: month-to-month is the standard you should demand. Some Clover resellers and some Toast add-on bundles still push multi-year agreements with early termination fees, and that is where most POS horror stories start.
One more thing the sales calls will not volunteer: every one of these companies makes most of its money on payment processing, not software. The software is the hook. Judge them like payment processors that happen to sell registers, because that is what they are.
Square: Best for Most Small Businesses
Square is the default for a reason. The free plan is actually usable: a full register app on a phone or tablet, unlimited items, basic inventory, digital receipts, and next-business-day deposits, with no monthly fee. Hardware starts with a card reader that costs less than lunch for two and scales up to a proper register. In-person processing runs in the neighborhood of 2.6 percent plus a small per-transaction fee as of this writing, with online transactions a bit higher, and Square publishes its rates plainly, which remains weirdly rare in this industry.
The real strength is the ecosystem. Square Invoices, Square Online, appointment booking, loyalty, email marketing, and payroll all plug into the same account and the same dashboard. For a solo operator or a small shop, that consolidation is worth more than any single feature, because it means one login, one support line, and one place where the money reconciles. If you also sell online, the built-in store is serviceable, though many owners pair Square with a dedicated site builder, a decision we walked through in our Shopify vs Squarespace vs Wix comparison.
The weaknesses are real but livable. Square’s flat-rate processing is simple, not cheap: at high card volume, an interchange-plus processor can beat it. Account holds are the most common complaint; Square’s risk systems occasionally freeze funds for review, which stings when cash flow is tight. And its restaurant features, while improved, are a general-purpose tool wearing an apron. If food service is your whole business, keep reading.
Clover: Best for Counter-Service and Franchise Setups
Clover, owned by Fiserv, is the hardware-first option. The terminals are legitimately nice: solid countertop stations, handheld units, and kitchen printers that feel more like appliances than accessories. Software plans start at a modest monthly fee and climb based on features, with processing rates that are competitive and sometimes lower than Square’s for card-present transactions, as of this writing. If you run a busy counter-service operation and want dedicated hardware at every station, Clover makes a strong case.
The catch is the sales channel. Clover is sold both directly and through a large network of banks and independent resellers, and your experience depends heavily on which door you walk through. Direct pricing is transparent. Reseller pricing can involve marked-up processing rates, equipment leases that cost multiples of the hardware’s retail price, and multi-year contracts with termination fees. The hardware is identical either way, which makes the contract the entire difference between a good deal and a bad one. If a bank bundles Clover with your business checking account, read the processing schedule line by line before signing anything.
Clover’s app market fills most gaps, from loyalty to advanced inventory, though the per-app subscriptions add up in a way Square’s bundled approach does not. For franchises and multi-location counter service, Clover’s centralized management and consistent hardware make it the operationally sane pick.
Toast: Best for Restaurants, Full Stop
Toast only does restaurants, and it shows. Menu management handles modifiers, 86ing items, and time-based menus without workarounds. Orders flow to kitchen display screens natively. Tip pooling, table maps, coursing, online ordering, and delivery integrations are first-class features rather than add-ons pretending to be. The handheld terminals let servers fire orders from the table, which pays for itself in table turns during a busy service. If you run a full-service restaurant, Toast is not just the best option in this comparison; it is the category standard.
Pricing has two doors. The starter route offers low or no monthly software cost in exchange for higher processing rates, which suits a new cafe watching every dollar of fixed cost. The subscription route charges a meaningful monthly fee with lower processing, which wins once volume is steady. Toast’s hardware is Android-based, wired-first, and restaurant-rugged, and you will buy it from Toast. Two cautions: the add-on list is long, and payroll, marketing, and scheduling modules each carry their own fees that can quietly double the monthly bill; and Toast processing is exclusive, so there is no shopping around for a better rate later. Model the total stack before you commit, not after.
The Side-by-Side Fee Math
Here is the math that matters, using a shop doing 20,000 dollars a month in card-present sales at an average ticket of 25 dollars, which is 800 transactions. At a representative flat rate of 2.6 percent plus 10 cents, processing costs about 600 dollars a month: 520 in percentage fees and 80 in per-transaction fees. Nudge that rate down to 2.3 percent and the bill drops to about 540. Nudge it up to 2.99 percent, which is where some starter plans and reseller contracts land, and you are near 680. That 140-dollar monthly spread is 1,680 dollars a year, which buys a lot of software subscription. This is why the free-software-higher-rate plans only make sense at low volume, and why the monthly fee is the wrong number to anchor on.
Per-transaction fees punish small tickets. A coffee shop with a 6-dollar average ticket pays that flat 10 or 15 cents on every cup, which at a 2.6 percent rate adds the equivalent of another 1.7 to 2.5 percentage points on each sale. High-ticket, low-count businesses barely notice per-transaction fees; high-count, low-ticket businesses should negotiate them hard or pick the plan that minimizes them. All three providers adjust their published rates periodically, so treat the numbers here as the shape of the math rather than a quote, and check current pricing pages before you sign.
Which One Should You Pick
Pick Square if you are a solo operator, a retail shop, a service business, or anyone who values one simple ecosystem and wants to start with zero fixed cost. Pick Clover if you want serious countertop hardware for counter service or multi-location standardization, and you are disciplined enough to buy direct or read a reseller contract like it owes you money. Pick Toast if you run a restaurant with table service or a kitchen of any complexity, and budget honestly for the add-ons you will actually use.
And whichever you choose, insist on month-to-month terms, buy hardware rather than leasing it, and reread your processing statement every quarter. The register should be the most boring part of your business. That is what winning looks like here.
The Hardware Shopping List, by Business Type
Hardware is where budgets quietly double, so here is what different businesses actually need on day one. A mobile service business, from house cleaners to consultants who occasionally take cards, needs exactly one thing: a pocket card reader paired with a phone, which any of these providers sells for under 60 dollars. A market stall or pop-up adds a tablet stand and maybe a portable receipt printer, still comfortably under 500 dollars all in. A retail counter wants a proper station: tablet or terminal, cash drawer, receipt printer, and a barcode scanner if your catalog runs past a few dozen items, which lands between 700 and 1,500 dollars depending on the brand. A cafe adds a customer-facing display and a kitchen printer. A full-service restaurant on Toast should budget for a main station, at least one handheld per two or three servers during peak, and a kitchen display screen, which pushes the opening bill into the low thousands.
Two rules keep this sane. Buy the minimum configuration that covers a normal day, not a holiday rush; every provider ships add-on hardware in two days, and renting a spare terminal for the December weekend is cheaper than owning one that idles for eleven months. And resist the beautiful bundle discount on gear you have not needed yet. The register systems are modular on purpose, and the upgrade path is always available. The downgrade path is a drawer full of expensive plastic.
A 30-Day Switching Plan
If you are moving from an old system, or from a cigar box and a prayer, a month is enough when you sequence it right. Week one: export everything from the old system while you still have access, meaning product catalog, customer list, gift card liabilities, and at least a year of sales reports for your accountant. Week two: build the new catalog, set tax rates, connect your accounting software, and run test transactions on every tender type, including the weird ones like partial refunds and split payments. Week three: train staff on real scenarios during slow shifts, with the old system still running as the fallback. Week four: cut over on your slowest day, keep the old system readable but not in use for one more billing cycle, and reconcile the first week of deposits line by line against your bank statement.
The one thing that cannot be rushed is gift cards. Outstanding balances are a legal liability, and not every provider imports them cleanly. Get written confirmation of how balances transfer before you pick a cutover date, or plan to honor old cards manually and track them on a spreadsheet until they burn down. It is unglamorous, but so is a customer holding a worthless card with your logo on it.
FAQ
Can I use my own payment processor with these POS systems?
Mostly no. Square and Toast require their own processing, and Clover runs on Fiserv rails through whichever reseller sold it to you. If keeping an existing processor matters, you need a POS built for processor flexibility, which is a different and generally more expensive category.
What does a POS system cost per month, realistically?
A solo operation on Square can genuinely run at zero fixed cost plus processing. A single-location shop on a paid plan typically lands between 30 and 100 dollars monthly before processing. A full-service restaurant on Toast with kitchen screens, handhelds, and a couple of add-on modules commonly runs several hundred dollars a month, with processing on top.
Should I lease POS hardware?
No. Leases in this industry routinely total three to five times the retail price of the equipment and often survive contract cancellation. Buy the hardware outright, even if it means starting with less of it.
Can I switch POS systems later?
Yes, but budget for pain. Product catalogs and customer lists export reasonably well; sales history, gift card balances, and loyalty data often do not transfer cleanly, and hardware never does. Pick with a three-year horizon.
