TL;DR — Quick Verdict
- A point-of-sale system has three separate cost layers — hardware, monthly software, and payment processing — and processing is the one that dominates long-term spend at roughly $2,600 per year on $100,000 of card volume.
- Square charges 2.6% + $0.15 per in-person swipe on its free plan; Clover runs 2.3%–2.6% + $0.10; Toast starts at 2.49% + $0.15 on its $69/month plan; Shopify POS is 2.6% + $0.10 on Basic.
- Hardware spans $49 for a mobile card reader to $1,899 for a Clover Station Duo — but “free” hardware bundles almost always cost more over three years through higher processing rates.
- Comparison result: on a $250,000/year card-present retailer, the effective-rate gap between the cheapest and priciest flat-rate processor works out to well over $1,000 annually.
- Recommendation: pick your processor by transaction mix and volume, not the advertised headline rate — and above roughly $250,000/year, get an interchange-plus quote before signing anything.
Roughly 16% of US restaurant payment volume now runs through a single vendor — Toast — according to industry analysis of the restaurant POS market, a concentration that tells you how much money moves through these systems. The point-of-sale decision looks like a hardware purchase. It is actually a multi-year payment-processing contract with a screen attached. A café owner comparing a $299 Square Terminal against a $1,899 Clover Station Duo is comparing the wrong numbers; the swipe fee will dwarf both within the first year. This guide breaks down all three cost layers — hardware, monthly software, and processing fees — across the four systems most small businesses actually shortlist: Square, Clover, Toast, and Shopify POS. You will get real 2026 prices pulled from vendor pricing pages, an original effective-rate calculation on realistic sales volumes, and a direct verdict on which system wins for retail versus restaurants. NerdWallet pegs total POS hardware anywhere from $59 for a reader to over $1,100 for a full register kit — the spread is enormous, and so are the traps.
The three cost layers, and why processing eats the rest
Every POS bill is built from three parts, and business owners routinely fixate on the smallest one. Hardware is a one-time purchase (or a lease you should almost always avoid). Software is a fixed monthly subscription. Payment processing is a percentage of every dollar you run — and it never stops.
Run the math on a modest retailer doing $100,000 in annual card sales at an average 2.6% + $0.15 with a $40 ticket. Processing alone costs about $2,600 in percentage fees plus roughly $375 in per-transaction cents — call it $2,975 a year, every year. A $500 hardware kit amortizes to nothing by comparison. That is why the headline rate matters more than the sticker price, and why “free” hardware offers deserve suspicion: vendors recover the hardware through a higher processing rate you pay indefinitely.
The layers also interact. Square, Clover, and Shopify let you buy hardware outright and keep a lower rate. Toast’s $0/month Starter Kit moves the cost into processing — pay-as-you-go pricing runs materially higher, and Toast requires you to process through Toast, so you cannot shop that rate elsewhere. Understanding margin, overhead, and market pricing is the difference between absorbing these fees and passing them through intelligently.
Processing rates compared: what you actually pay per swipe
Here is the single most important table in this guide — the card-present rate each system charges, because that percentage compounds across every transaction for the life of your account.

Two things jump out. Toast’s in-person restaurant rate is the lowest card-present flat rate on this list at 2.49% + $0.15 — but only on the paid plan, and only if your online order share is small, because its 3.50% online rate is steep. Shopify’s per-transaction cent charge of $0.10 is the lowest, which favors businesses with lots of small tickets. If you are also weighing an online store’s setup and operating expenses, note that in-person and online rates diverge sharply on every platform.
Hardware pricing: from $49 readers to $1,899 stations
Hardware is where the sticker shock lives, and where the widest price gaps appear. A mobile card reader that plugs into a phone costs almost nothing; a dual-screen countertop station with a printer and cash drawer costs as much as a used car payment.

The lease warning is the one every reseller buries. A Clover Station that costs about $1,800 to buy outright can run $4,000–$6,000 over a 48-month lease, and those leases are typically non-cancelable even if you close the business. Buy hardware outright whenever cash flow allows — it also gives you leverage to negotiate the processing rate. Shopify sits in the middle, with readers from $49 up to full countertop kits around $459, and it leans on iPad-based setups rather than proprietary terminals.
How a POS quote actually gets built: a real scenario
Consider a single-location coffee shop doing $30,000 a month in card sales, almost entirely in-person, with a $12 average ticket — about 2,500 transactions monthly. On Square’s free plan at 2.6% + $0.15, the percentage fee is $780 and the per-transaction cents add roughly $375, for about $1,155 a month, or near $13,860 a year. Hardware is one Square Terminal at $299. Software is $0.
Now model the same shop on Toast’s Point of Sale plan. Software is $69/month ($828/year). Processing at 2.49% + $0.15 yields about $747 in percentage fees plus $375 in cents, roughly $1,122 monthly. Toast is cheaper on the percentage but adds the subscription — and layers on module fees for online ordering (~$75/month), loyalty (~$50/month), and a kitchen display system if you need one. Those add-ons are where a $69 plan quietly becomes $200–$400 a month.
The lesson: the winning system depends on your ticket size, transaction count, and how many software modules you genuinely need. A high-volume, low-ticket business is punished by per-transaction cents; a low-volume, high-ticket business barely notices them. If you are still deciding whether to run lean or staff up, our breakdown of the true cost of hiring a first employee pairs directly with these POS math exercises.
Square vs. Clover: Which Is Better for a Small Retailer?
These two dominate general retail, and they represent opposite philosophies. Square is a software company that gives away the POS and monetizes the swipe: no monthly fee on the free plan, a flat and predictable 2.6% + $0.15 card-present rate, cheap hardware starting at $59, and next-business-day deposits at no charge. Clover is a hardware-forward system tied to Fiserv, with sleeker dual-screen stations, a lower headline rate (as low as 2.3% + $0.10 on some plans), but real monthly software fees and hardware that starts higher.
Clover’s lower percentage looks attractive until you account for the monthly software cost and the reseller ecosystem, where tiered pricing and long contracts are common. Square’s flat rate is higher on paper but comes with no contract, no chargeback fee, and radical predictability — you can calculate your exact cost in seconds. Clover rewards businesses that buy hardware outright directly from Clover.com and process enough volume to justify the subscription; Square rewards businesses that want zero commitment and simple math.
Verdict
For a new or low-volume retailer under roughly $12,000/month who values predictability and no contract, Square wins on total cost and simplicity. For an established retailer above that volume who buys hardware outright directly from Clover and wants customer-facing screens and deeper inventory tools, Clover’s lower percentage rate can pull ahead — but only if you avoid leases and tiered reseller pricing. Above $250,000/year, neither flat rate is your best option; request an interchange-plus quote.
What most people get wrong about POS costs
Three mistakes show up again and again, and each one costs real money.
Chasing the lowest hardware price. Buying the cheapest terminal while ignoring a processing rate that is 0.3% higher is a losing trade. On $200,000 in annual volume, 0.3% is $600 a year — every year — versus a one-time hardware saving of maybe $200. Correct action: compare effective processing rates first, hardware second.
Signing a hardware lease. The “free” or financed hardware path is almost always the most expensive over three to five years, and the contracts are typically non-cancelable. A reseller quoting $100/month for a leased station is charging you $4,800 over 48 months for something that costs $1,800 to own. Correct action: buy outright, or walk.
Ignoring the add-on and junk-fee stack. Restaurant POS invoices routinely land two to three times higher than the quoted base, once you add online ordering, loyalty, PCI compliance fees (around $9.95/month on some systems), statement fees, and batch fees. Correct action: price the full module stack you will actually use, and ask for every recurring fee in writing before signing. If a dispute ever escalates, understanding business lawsuit attorney costs and settlement math matters, but most POS disputes are contract-term problems you can avoid up front.
Who should choose which system — and is it worth it?
Match the system to the business, not the other way around. If you run a full-service or quick-service restaurant, Toast is purpose-built: spill-resistant hardware, kitchen display integration, and the lowest card-present restaurant rate at 2.49% + $0.15 on the paid plan. The trade-off is processor lock-in and a module stack that inflates the monthly bill. If you run general retail with an online component, Shopify POS is the most cost-effective option when you already pay for a Shopify plan, because basic in-person selling (POS Lite) is included free and inventory syncs across channels.
If you are a new, low-volume, or mobile business — a market vendor, a service provider who occasionally sells product, a pop-up — Square’s free plan with a $59 reader is nearly unbeatable on total cost and has no contract to trap you. If you want premium countertop aesthetics and deep inventory control and you process enough volume to absorb the subscription, Clover earns its place, provided you buy hardware outright.
Is a paid tier worth it? Only above the break-even volume. Square Plus at $49/month pays for itself only past roughly $49,000/month in in-person sales, where the rate discount covers the subscription. Below that, the free plan is cheaper despite the higher rate. The same logic governs whether you should weigh a franchise versus independent fee structure, where processing terms are sometimes dictated by the franchisor. Run your own numbers before upgrading — the break-even point is specific to your volume and ticket size.
Frequently Asked Questions
What is the cheapest POS system for a small business?
Square’s free plan is the cheapest entry point: $0/month software, a $59 contactless-and-chip reader, and 2.6% + $0.15 per in-person transaction with no contract. Shopify POS Lite is also free if you already pay for a Shopify plan. For very low volume, the absence of a monthly fee usually beats a competitor’s slightly lower percentage rate, per NerdWallet’s 2026 pricing analysis.
Why did Square’s processing fees go up?
Square overhauled its pricing in October 2025, consolidating all business types into three tiers and raising the free-plan in-person per-transaction fee from $0.10 to $0.15, plus lifting the free-plan online rate to 3.3% + $0.30. Many older articles still cite the pre-overhaul 2.6% + $0.10 figure, which is outdated. Always confirm current rates on Square’s official pricing page.
Should I buy or lease my POS hardware?
Buy outright whenever possible. A Clover Station that costs roughly $1,800 to purchase can total $4,000–$6,000 over a 48-month lease, and those leases are typically non-cancelable even if your business closes. Buying also gives you leverage to negotiate a lower processing rate. Leasing only makes sense for a business with severe short-term cash constraints, and even then, read the termination terms carefully.
Can I use my own payment processor with Toast?
No. Toast requires you to process payments through Toast — you cannot bring a third-party processor. This lock-in is central to its business model and means its Starter Kit’s higher pay-as-you-go rate of roughly 2.99%–3.69% + $0.15 cannot be shopped elsewhere. Square, Clover, and Shopify offer more processor flexibility, though each strongly incentivizes using its own in-house processing.
How We Researched This Article
This analysis draws exclusively on vendor pricing pages and reputable secondary aggregators verified in July 2026. Processing rates, plan fees, and hardware prices for Square, Clover, Toast, and Shopify POS were collected from each company’s published pricing documentation and cross-referenced against independent breakdowns from NerdWallet, Merchant Maverick, and Tech.co. Where sources disagreed — most notably on Square’s rates, some of which still reflect pre-October-2025 figures — the current published rate was treated as authoritative and the outdated figure was flagged in the text.
The effective-cost scenarios (the coffee-shop and retailer models) are modeled, not measured: they apply each vendor’s stated rate formula to hypothetical but realistic volume and ticket-size assumptions, and are labeled as such. Actual costs vary with card mix, average ticket, online-versus-in-person split, custom-negotiated rates for merchants above $250,000/year, and add-on module selection, none of which a published rate table captures. Restaurant-specific rates were additionally checked against POSUSA. This research was last conducted in July 2026. Rates in this fast-moving category change often; confirm every figure against the vendor’s live pricing page before making a purchase decision. All figures were verified against named primary sources before publication.
