Clover and Square are the two most common point-of-sale platforms for small and midsize US businesses, and they take fundamentally different routes to the same job: accepting payments, tracking sales, and managing a storefront or service business. Clover is a hardware-led system built on the Fiserv (formerly First Data) processing network, sold and serviced through banks and merchant services providers. Square is a software-first platform that bundles its own processor, hardware, and apps into one flat-rate account you can open online in minutes.
ProTech Payments, a merchant services provider in Katy, Texas serving Houston, Sugar Land, Cypress and Fort Bend County, sets up and supports Clover for restaurants, retail, auto repair shops and service businesses across the region. The reason the comparison matters is money: a business processing $50,000 a month can pay $1,500 or more in card fees, and the gap between Square’s locked 2.6% plus 10 cents and an interchange-based Clover plan placed through a real provider can run several thousand dollars a year. Choosing well also means choosing who answers the phone when the terminal goes down on a Friday night.
This comparison covers what each platform is, how the hardware and software differ, what you actually pay, which verticals each one fits, and the Texas-specific angle around surcharging and dual pricing that changes the math for both.
What Clover and Square are
Clover is a POS operating system owned by Fiserv. The hardware runs Clover’s Android-based software, but the merchant account behind it is opened through a bank or an independent provider like ProTech Payments. That structure means pricing is negotiable, processing runs on the Fiserv network that handles a large share of US card volume, and support comes from the provider who sold the account rather than a generic call center.
Square, owned by Block, is the opposite design. Square is its own payment facilitator, which means you do not get a traditional underwritten merchant account. You sign up, accept Square’s published flat rate, and start taking cards the same day. The simplicity is real, and so is the tradeoff: Square owns the risk, so it can freeze or hold funds at its own discretion, and the flat rate stays flat no matter how large your volume grows.
The processing model underneath each
Both platforms route Visa, Mastercard, Discover and American Express transactions through the same card networks, and both pay the same interchange fees set by Visa and Mastercard. The difference is what sits on top of interchange. Square wraps interchange, assessments and its own margin into a single posted rate. Clover, placed through a provider, can be priced on interchange-plus, where you see the true network cost plus a fixed markup. For a deeper look at the two structures, see our guides to interchange-plus pricing and how interchange fees work.
Hardware compared
Clover sells a tiered hardware family: the Clover Go mobile reader, the Flex handheld, the Mini countertop, and the Station Duo full register with a customer-facing screen and cash drawer. The hardware is purpose-built and durable, the EMV chip and contactless reader are certified to current standards, and you can buy outright or finance the equipment over time.
Square’s lineup mirrors this with the Square Reader, Square Terminal, Square Register, and Square Stand that turns an iPad into a register. Square hardware costs less up front and the Reader is famously cheap, but the ecosystem is more closed, and replacing or expanding hardware ties you further into Square.
Ownership and lock-in
This is the practical divide. Clover hardware is more expensive but is sold through providers who can offer equipment financing and who service the device locally. Square hardware is inexpensive but only works inside Square. Note that Clover devices are also bound to the original provider’s processing, so buying a used Clover off a marketplace usually means it will not activate on a new account. For a broader look at register options across categories, our roundup of the best POS systems for small business breaks down the field beyond these two.
Pricing and fees compared
Square’s headline rates are public and uniform: 2.6% plus 10 cents for in-person tapped or dipped cards, 2.9% plus 30 cents for online, and 3.5% plus 15 cents for keyed transactions. There is no monthly account fee on the base plan. Clover pricing depends on the provider and the plan, but a competitively placed interchange-plus account frequently lands well below Square’s effective rate once monthly volume climbs.
The table below shows representative effective costs. Square figures use its published rates. Clover figures assume an interchange-plus plan placed through a provider at a typical blended effective rate; your actual rate depends on card mix and volume.
| Factor | Square | Clover (via provider) |
|---|---|---|
| In-person card rate | 2.6% + 10 cents flat | Interchange + markup, often 2.1% to 2.4% effective |
| Online card rate | 2.9% + 30 cents | Gateway plus interchange-plus |
| Keyed rate | 3.5% + 15 cents | Interchange + markup |
| Monthly software fee | $0 base, paid tiers extra | $0 to ~$60 depending on plan |
| Account type | Payment facilitator (aggregated) | Dedicated merchant account |
| Funds-hold risk | Higher (aggregator) | Lower (underwritten) |
| Negotiable pricing | No | Yes |
| Processing network | Square (Block) | Fiserv / First Data |
The pattern is consistent: Square wins on simplicity and low volume, Clover wins on cost as volume rises and on stability of funding. A business doing $20,000 a month may not notice the gap, while one doing $80,000 a month often saves real money moving to interchange-plus Clover.

PCI compliance costs
Both platforms must meet PCI DSS standards. Square folds compliance into its model. Clover accounts carry a PCI compliance program through the provider, sometimes with a fee, and ProTech handles that for merchants as part of PCI compliance support. Factor this into the monthly comparison so you are comparing full cost, not just the card rate.
Software, apps and features
Clover runs an app marketplace where you add inventory, employee management, online ordering, loyalty and reservations as needed. The base register software covers most retail and restaurant needs, and the marketplace fills gaps. Because Clover is Android-based, third-party developers build for it, and integrations with accounting and back-office tools are broad.
Square’s software is more unified out of the box. Inventory, online store, appointments, payroll and marketing all live in one Square dashboard, which is a genuine strength for a single operator who wants everything in one login. The tradeoff is that deep customization and certain industry-specific workflows can be thinner than Clover’s specialized apps.
Where each platform handles channels
For omnichannel selling, both offer online payments and a payment gateway for ecommerce, plus in-store payments and mobile payments for the floor and the field. Clover, placed through a provider, can also connect a separate virtual terminal for phone and mail orders, which suits B2B and service businesses that key in cards. If recurring billing matters, both support subscriptions, and our recurring billing guide explains how to set it up cleanly.
Best fit by business type
The right choice tracks closely to vertical and volume.
Restaurants and food service
Clover dominates table service and quick service because of its kitchen printing, tipping, course firing and tableside ordering, and providers can tailor the setup. ProTech configures Clover for restaurant merchant services across Houston and Katy. Square works well for cafes, food trucks and counter-service spots that want simple, fast checkout. Compare the field in our best restaurant POS system breakdown.
Retail and service businesses
Retail with real inventory depth and barcode scanning leans Clover, supported by retail merchant services tuned to SKU count and reporting. Service businesses such as salons, auto repair and home services often prefer Clover’s appointment and invoicing apps placed alongside salon and spa or auto repair merchant accounts. Square fits solo operators and pop-ups who value speed of setup over depth.
Common mistakes when choosing
The biggest mistake is comparing only the headline rate. Square’s 2.6% looks clean, but a Clover interchange-plus plan can deliver a lower effective rate at volume, and the only way to confirm is to read both against your real statement.
The second mistake is ignoring funds-hold risk. Square, as an aggregator, can freeze deposits with little notice if a transaction pattern trips its risk model, which is dangerous for businesses with large tickets or seasonal spikes. A dedicated Clover merchant account is underwritten up front, lowering that risk.
The third mistake is buying hardware before settling the account. Clover devices are locked to the provider that activated them, so a used unit usually will not work on a new account. Choose the provider and plan first, then buy or finance the right hardware. Our guide to choosing a payment processor for a small business walks through the full checklist.
The Texas angle: surcharging and dual pricing
Texas allows credit card surcharging and dual pricing within the rules set by Visa, Mastercard and state law, which changes the economics of both platforms. With a compliant program, the card fee is offset at the point of sale, so the effective cost of card acceptance can drop toward zero for the merchant on credit transactions.
Clover, placed through a provider, supports compliant dual pricing and cash discount programs with the required signage and receipt disclosure built in. ProTech sets these up so the math is correct and the program follows Visa caps and Texas disclosure requirements. Square’s flat-rate model is less flexible for structured surcharging, and merchants who want to eliminate processing cost usually move to a provider-placed Clover.
Local setup and support
For businesses in the area, ProTech provides hands-on setup through merchant services in Katy, Houston and Sugar Land. You can model your own savings first with the dual pricing savings calculator before deciding. For the legal detail, our cash discount program in Texas post covers the compliance rules.
Frequently asked questions
Is Clover cheaper than Square?
It depends on volume. At low monthly card volume Square’s flat 2.6% plus 10 cents is competitive and has no monthly fee. As volume rises, a Clover interchange-plus account placed through a provider usually delivers a lower effective rate, sometimes saving thousands a year. A statement analysis is the only way to confirm which is cheaper for your specific card mix.
Can I switch from Square to Clover?
Yes. You open a dedicated merchant account, get a Clover device provisioned to that account, and migrate your menu or inventory. Existing Square hardware will not transfer because it only works inside Square, so the move involves new Clover hardware, which can be financed. ProTech handles the setup and data import.
Does Clover hold funds like Square does?
Less often. Square is a payment aggregator and can freeze deposits at its discretion based on its risk model. A Clover account is a dedicated merchant account underwritten in advance, so the funding relationship is more stable, which matters for high-ticket and seasonal businesses.
Can both platforms surcharge or run dual pricing in Texas?
Texas permits compliant surcharging and dual pricing under Visa, Mastercard and state rules. Clover placed through a provider supports compliant programs with the required signage and disclosure. Square’s flat-rate structure is less suited to structured surcharging, so merchants who want to offset card fees generally choose provider-placed Clover.
Which is better for a restaurant?
Clover is the stronger choice for full-service and quick-service restaurants because of kitchen printing, tipping, tableside ordering and course firing. Square fits counter-service cafes and food trucks that want fast, simple checkout. The decision tracks how complex your service flow is.
Do I need a separate payment gateway with either one?
For in-person sales, no, both include card acceptance. For ecommerce or keyed phone orders, you add an online checkout or a virtual terminal. Clover through a provider can connect a dedicated gateway and virtual terminal, which suits B2B and service businesses that take cards over the phone.
