Clover vs Square vs Shopify: Best POS for Retail 2026

For most single-store retailers, Square is the safest starting point. It is the only one of the three with a genuinely free software tier, a published rate that is the same for every merchant, and nothing to sign before you take your first payment.

But do not stop there. Shopify is the better answer the moment online selling matters, and Clover is the only one of the three that lets a high-volume store negotiate its own processing rate instead of accepting whatever is printed on the rate card.

Part of what makes this comparison awkward is that these are not the same kind of product. Two are payment companies that built POS software, one is an ecommerce platform that added a till, and only one of the three reaches you through a middleman rather than from the company that builds it.

Timing matters as well. Square retired roughly 18 vertical plans in October 2025 and replaced them with three, so most comparison pages still describe a Square lineup that no longer exists, while Clover's price still depends on which reseller picks up the phone.

I have compared the software fees, processing costs, hardware commitments, and exit risks across all three so you can pick the right one for your store, not the one with the lowest advertised monthly price. The differences that matter in the Clover vs Square vs Shopify decision show up in the contract rather than the feature list, and each of the three wins at least one of the eight rounds below.

Key Takeaways

Square’s unified Free, Plus, and Premium plans replaced 18 vertical plans in October 2025, giving it the most transparent and predictable pricing of the three.
Clover hardware is locked to Fiserv’s network and cannot be reprogrammed for another processor, so switching means buying entirely new equipment.
Shopify POS Pro at $89 per location sits on top of an ecommerce plan, but it is the only one that natively unifies online and in-store inventory.
Clover is the only one that can offer interchange-plus pricing through a reseller, which can beat flat rates above roughly $25,000 to $30,000 a month in card volume.
Square for Retail scores 4.7 on Capterra from 495 reviews, Shopify POS 4.6 from 247, and Clover 3.8 from 580, the largest sample and the lowest score.
Shopify POS Go was discontinued from new US sales in August 2024 and existing units keep working in mobile selling mode until May 2027, not September 2026 as many competitors still claim.

Clover vs Square vs Shopify: The Short Version

Here is how the structural differences look side by side before you read the arguments. If Shopify is not really in your running, my Clover vs Square head-to-head goes deeper on those two.

	Square Best for in-person-first stores that want no contract	Shopify Best for stores that also sell online	Clover Best for high-volume stores wanting a negotiated rate
Software cost	Free $0, Plus $49/location, Premium $149/location	Ecommerce plan $39 to $399 monthly plus POS Pro $89/location	Roughly $0 to $105 a month depending on tier and reseller
In-person rate	2.6% + 15c on Free, 2.5% + 15c on Plus, 2.4% + 15c on Premium	2.4% to 2.6% + 10c depending on plan	Set by whichever reseller sold you the account, not published
Online rate	3.3% + 30c on Free, 2.9% + 30c on Plus and Premium	Varies by plan under Shopify Payments	Also set by the reseller; flat, tiered or interchange-plus
Third-party processor fee	None (Square is the processor)	2% on Basic, 1% on Grow, 0.6% on Advanced, 0.2% on Plus; waived on Shopify Payments	Not applicable (processing goes through the reseller)
Hardware range	Free magstripe reader to $899 Register	$49 reader to $349 POS Terminal, plus Tap to Pay	Go about $49 to Station Duo $1,649 to $1,899
Contract	Month to month	Month to month	Varies by reseller; often 36 to 48 month lease
Sold by	Direct	Direct	60+ certified reseller partners
Multi-location	Premium tier unlocks cross-location returns and transfer orders	POS Pro required for cross-location returns and inventory counts	No volume discount; each location gets its own hardware, subscription and processing agreement
Offline card payments	Cash and manual payments always; card offline not confirmed	Cash and manual always; offline card payments with admin activation	Cash and manual always; card offline depends on reseller setup

These Three Are Not the Same Kind of Product

Square and Clover are payment companies that built POS software. Shopify is an ecommerce company that added a till. Clover alone is sold through middlemen, and almost every difference downstream traces back to that.

Square is a payments company first. It sells direct, publishes one rate card for everyone, and acts as the merchant of record. That is why its pricing is transparent and why there is nothing to negotiate.
Shopify is an ecommerce platform first. Its POS is an extension of the online store, which is why it needs an ecommerce subscription underneath it and why its inventory story is the strongest. It also explains the third-party processor surcharge: Shopify would rather you used Shopify Payments.
Clover is owned by Fiserv but mostly sold by other people. Fiserv’s own certified partner directory lists more than 60 approved resellers, and each one sets its own markup, contract terms, and processing model.

Most of those resellers are ISOs, independent sales organizations authorized to sell payment processing on a larger processor’s behalf. An ISO takes Fiserv’s platform wholesale and prices it retail.

That is why two merchants get different quotes for the same hardware, why the contract risk is concentrated on Clover, and why support quality varies by who sold the system to you. Fiserv’s directory names its approved partners but says nothing about why their prices differ.

The practical consequence is this. With Square and Shopify you are comparing published prices, and the number on the page is the number you pay. With Clover you are comparing a quote, and a quote moves in both directions: a strong reseller can undercut the published flat rates, and a weak one can bundle a lease, a longer term, and fees the alternatives do not carry.

So before you compare Clover against anything, ask the reseller four things:

Pricing model: flat rate, tiered, or interchange-plus.
Term: how many months, and whether it renews automatically.
Hardware: bought outright or financed on a lease.
Fees: setup, early termination, and anything else buried in the paperwork.

1. Best for Transparent, Predictable Pricing: Square

The Winner: Square

Square wins on pricing clarity because it is the only one of the three where you can know your monthly bill before you talk to anyone. Square retired roughly 18 vertical-specific subscriptions on October 6, 2025 and replaced them with three unified plans: Free at $0, Plus at $49 per location, and Premium at $149 per location. Every competing comparison page I have seen still refers to Square for Retail Plus and Premium, which no longer exist under those names.

What each tier gates matters. Free covers item creation, discounts, refunds, and basic reporting. Plus adds inventory management, vendor management, and COGS reporting. Premium unlocks cross-location returns, transfer orders, and 24/7 support.

Shopify’s structure, for contrast, layers an ecommerce plan from $39 to $399 monthly (or $29 to $299 on annual billing) plus POS Pro at $89 per location, or about $79 with annual billing. Shopify Plus merchants get 20 POS Pro locations included before the per-location fee applies.

Clover software runs roughly $0 to $105 a month depending on tier and reseller, with restaurant tiers higher. The spread is the finding, not a gap in my research: Clover’s own pricing pages do not render their own prices in a way that can be captured, and reseller quotes for the same plan differ by tens of dollars.

For a single store, the monthly software picture looks like this:

Square Plus: $49
Shopify Basic plus POS Pro: $39 plus $89 equals $128
Clover mid-tier: roughly $50 to $85 before hardware

Clover also has no multi-location volume discount. Each additional location needs its own hardware, subscription, and processing agreement.

Best for a retailer who wants to know exactly what they will pay every month without negotiating. Skip if you are already doing serious online sales and need a unified catalog, where Shopify’s higher software cost buys something the other two cannot match. Clover’s quoted price is the only one you can negotiate down, but you have to be willing to have that conversation.

2. Best for Processing Rates: Shopify, Narrowly

The Winner: Shopify

Shopify Payments runs roughly 2.4% to 2.6% plus 10 cents in person depending on your plan, Square runs 2.6% plus 15 cents on Free, 2.5% plus 15 cents on Plus, and 2.4% plus 15 cents on Premium, and Clover’s rate is set by whichever reseller sold you the account. The subscription is the small number. The rate is the big one, and a ten cent difference per transaction decides more than most buyers expect.

The Square rate story is worth telling properly because it explains why you will see conflicting numbers online. Square moved from 2.6% plus 10 cents to 2.6% plus 15 cents, effective February 25, 2025 for new sellers and March 27, 2025 for existing ones. A grandfathered cohort still pays the old fixed fee, so both numbers are true for different merchants.

Square’s other rates, for completeness:

Online and invoices: 3.3% plus 30 cents on Free, 2.9% plus 30 cents on Plus and Premium.
Keyed-in and card on file: 3.5% plus 15 cents on every plan.

Shopify’s catch, which competitors describe only as “up to 2%,” is that the third-party processor surcharge is 2% on Basic, 1% on Grow, 0.6% on Advanced, and 0.2% on Plus, waived entirely on Shopify Payments. So Shopify’s good rate is conditional on using Shopify’s own processor.

Square’s rate card is the only one that is the same for everyone, and Clover’s is the only one you can argue with. For a store that will use Shopify Payments and process mostly in person, Shopify’s 10 cent fixed fee often edges out Square’s 15 cents at the same percentage.

3. Best for Hardware: Square

The Winner: Square

Square has the widest range at the most predictable prices, and two of the three now let you take cards on a phone you already own. The lineups:

Square, with financing: Register $899 or $44 a month over 24 months, Handheld $399 or $37 a month, Terminal $299 or $27 a month, Stand $149, Kiosk $149, plus a free or low-cost magstripe reader.
Clover, and the variance: Go about $49, Flex $599 to $749 for the same device depending on who quotes it, Mini about $799, Station Solo $1,349 to $1,699, Station Duo $1,649 to $1,899. The spread is per reseller, not per model.
Shopify: POS Terminal about $349, sold alone or as a countertop kit, plus a wired Tap and Chip reader.

A correction on POS Go: Shopify discontinued it from new US sales on August 28, 2024. Existing units remain supported in mobile selling mode until May 26, 2027, not September 2026 as many comparisons still claim. Shopify now points buyers at Tap to Pay or the Verifone Victa Mobile.

Tap to Pay is the underrated answer. Both Square and Shopify accept contactless payments on an unmodified iPhone or Android at the standard in-person rate with no reader to buy. No equivalent Clover offering was confirmed. For a small store this removes the hardware question entirely.

Best for a retailer who wants a clear hardware price and the option to start with just a phone. Skip if you want a single, purpose-built countertop device and are already on Shopify, where the POS Terminal is the cleanest setup. Clover’s hardware is the most purpose-built for a busy counter, but you pay for that in commitment length.

4. Best for Staying Free to Leave: Anyone But Clover

The Winner: Square and Shopify, jointly. The loser is the story here.

This is the round most likely to cost you real money, and it is the one the vendor sales call will not cover. Clover devices are provisioned to Fiserv’s network and cannot be reprogrammed for another processor. Switching processors means buying entirely new hardware.

The mechanics, in order:

The lease is long: hardware is frequently financed on 36 to 48 month terms that are non-cancelable.
The lease outlives the account: it is typically held by a separate finance company, not Fiserv, so closing the merchant account does not end it.
Leaving early costs the balance: early termination generally means owing what remains, with one source citing termination fees of $295 to $595 on top.

The numbers make it concrete. A Station Duo bought outright at about $1,899 plus $84.95 a month in software totals roughly $4,957 over 36 months. The same equipment financed at about $180 a month totals about $6,480, a difference of roughly $1,500 for identical kit. A second example puts a $1,799 Station Duo on a 36-month lease above $7,200 in total payments.

Merchant reports back this up. Users describe still owing on hardware after switching, rate creep beyond the signed rate, and the fact that “every machine needs to be programmed to one sole processor.” BBB complaints document billing continuing after cancellation requests.

Advertisment ⓘ

Square and Shopify, by contrast, are month to month with no termination penalty. The honest consolation for Clover: buying the hardware outright rather than leasing avoids most of this, and a good reseller will sell it that way if asked. Before you sign anything, ask what you own, what you lease, and what the hardware is worth if you change processor. If the answer is “nothing,” walk away.

5. Best for Inventory Across Locations: Shopify

The Winner: Shopify

Shopify wins because its multi-location inventory tools are clearer and cheaper per location than Square’s, and Clover does not really compete here without paid add-ons.

Shopify POS Pro is the gate for inventory counts, purchase orders, low-stock alerts, and returns or exchanges at any location rather than only where the sale happened.

Transfers are the part that matters day to day. Stock moving between your stores, or in from a supplier, carries in-transit, ready-to-ship, and transferred states, and the receiving store can accept a partial shipment without breaking the count.

The tier gates side by side:

Shopify: $89 per location for POS Pro, on top of an ecommerce plan.
Square: $149 per location for Premium, the tier with cross-location returns and transfer orders.
Clover: priced per location with no volume discount at all.

Square Plus adds inventory management, vendor management, and COGS reporting, but the cross-location piece sits one tier higher. Across three stores that is $447 a month on Square Premium against $267 on Shopify POS Pro plus a single ecommerce plan underneath.

Clover includes basic inventory in the box, with multi-location and advanced features generally requiring paid apps from the Clover App Market. There is also no volume discount, so every additional location needs its own hardware, its own software subscription, and its own processing agreement.

Square Premium genuinely covers most of the same ground, and its cross-location returns work the way Shopify’s do. Clover’s per-location independence suits franchises where each site is run and banked separately. But if stock moves between your stores and you want that managed in one system, Shopify is the most cost-effective answer.

6. Best for Selling Online Too: Shopify

The Winner: Shopify

This is not close. Shopify POS is an extension of an ecommerce platform, so one catalog, one customer record, and one inventory count serve both channels. Buy online pick up in store and cross-channel returns work natively.

The other two were designed around the register first, and that is the real difference. Selling online with either means keeping a second system roughly in step with the first, and the reconciliation is more manual than anyone admits at the demo.

Square: a genuinely usable free online store, but a website builder attached to a POS rather than a full ecommerce platform. Depth of customization and SEO control are the gap.
Clover: the weakest of the three online. Selling online generally means a third-party integration, with the syncing and fragmented customer data that implies.

Shopify’s own comparison page claims that 84% agree Shopify POS better integrates their channels, 70% agree it increases operational efficiency, and that it delivers 200+ product enhancements every year since 2021. It also markets tracking every product across 1,000 locations. Those are Shopify’s marketing claims, not independent findings, and I have not leaned on them here.

Worth saying plainly: much of the comparison content published on this topic comes from agencies that sell Shopify implementations, and several of the pages ranking for this query are written by self-described Shopify partners. Weight every “Shopify wins” conclusion accordingly, including mine, which rests on the pricing and feature evidence above rather than on anyone’s partner program.

Best for any store that sells online now or will within the next two years. Skip if online is genuinely a side channel and you want the simplest in-person setup, where Square’s free online store is adequate for click and collect at no extra software cost. Clover is fine online when online is a side channel, but it was never built to be the hub.

7. Best for Support and Day-to-Day Reliability: Square

The Winner: Square

All three have real complaints, but the independent numbers are clear. On Capterra, Square for Retail holds 4.7 out of 5 from 495 reviews, Shopify POS 4.6 from 247, and Clover 3.8 from 580, the largest sample and the lowest score.

Shopify POS deserves its consolation on those numbers. Its 4.6 sits a tenth of a point behind Square on a much smaller sample, because most Shopify merchants sell online only and never touch the POS. The platform itself holds 4.5 from 6,712 reviews, a far larger vote of confidence than the POS listing shows on its own.

What merchants actually complain about, attributed as user reports:

Square: hard to reach support during an outage, and account holds with 90-day fund freezes after an unusual transaction. Margin erosion at volume is also a recurring theme.
Shopify POS: peripherals like receipt printers and barcode scanners disconnecting daily and needing manual resets. Core functionality spread across paid add-ons frustrates smaller stores.
Clover: slow support with repeated transfers, rate creep beyond the signed rate, and billing continuing after cancellation requests.

The structural reason Clover’s support varies ties back to the framing section: you are supported by whoever sold you the system, not by Fiserv. A good reseller can be more responsive than any vendor call center, but a bad one leaves you stranded.

Offline behavior: Shopify POS takes cash and manual payments offline for everyone, with offline card payments requiring admin activation. Merchants describe the mode as workable but not smooth. Neither Square nor Shopify publishes exact transaction or dollar caps for offline card acceptance, so there are none to quote here.

Square’s edge is narrow, but its larger review base and higher satisfaction score on the retail-specific listing make it the safer bet for day-to-day reliability.

8. Best for High-Volume Stores Outgrowing Flat Rates: Clover

The Winner: Clover

Clover wins this round because it is the only one of the three where a standard seller can realistically get interchange-plus pricing. Flat rate charges one blended percentage regardless of card type. Interchange-plus passes through the card network’s actual wholesale rate plus a fixed processor markup, so a merchant with a debit-heavy mix stops subsidizing rewards-card transactions.

Analyses put the inflection point somewhere around $25,000 to $30,000 a month in card volume, above which a well-negotiated interchange-plus account can beat flat rate. At $50,000 a month with a 50/50 in-person/online split, Square’s flat rate costs roughly $1,475 a month in fees, a figure a negotiated interchange-plus deal can undercut.

Who can actually offer it:

Square: flat rate only, with no interchange-plus option for standard sellers.
Shopify: Shopify Payments is flat rate by plan.
Clover: resellers routinely market interchange-plus, because the pricing model is theirs to set.

The honest counterweight: the same reseller relationship that unlocks a negotiable rate is the one that brings the lease and the rate creep from round four. The upside and the risk come from the same place. At genuinely large volume both rivals answer back, since Shopify Plus negotiates custom terms and Square Pro, its tier for businesses processing over $250,000 a year, comes with hardware discounts and a dedicated account manager.

Best for a store doing more than roughly $25,000 to $30,000 a month in card volume, especially with a debit-heavy mix. Skip if you are under that threshold, where the simplicity of a published flat rate outweighs the potential savings of a negotiated one.

What It Costs to Leave

The question nobody asks at the demo is the one that separates a bad month from a bad three years.

	Square	Shopify	Clover
Contract term	Month to month	Month to month	Varies; often 36 to 48 month lease
Termination fee	None	None	Remaining lease balance plus possible $295 to $595 fee
Hardware portability	Owned outright; holds some resale value	Readers are inexpensive; hardware works with the platform you leave	Provisioned to Fiserv; worthless to another processor
Data export	Catalog and customers as CSV; sales history is the hard part	Catalog and customers as CSV; the ecommerce store is the bigger migration	Catalog and customers as CSV; export before cancelling

Product catalogs and customer records generally come out as CSV on all three, so the customer list you spent years building is portable. Historical sales data is the difficult part everywhere, and it rarely lands in a new system in a usable shape.

That makes the order of operations matter more than the platform:

Export first, cancel second: pull the catalog and customer list as CSV while the account is still open.
Archive the sales history separately: it is the data least likely to survive the move, so keep your own copy of it.
On Clover, check the lease on its own: closing the merchant account does not close a lease held by a finance company.

Before signing anything, ask what you own, what you lease, and what the hardware is worth if you change processor. On Clover, the answer to that last question is zero.

How I Compared These Three

I built this comparison on each vendor’s own published pricing and plan terms in US dollars, Shopify and Square help documentation, Fiserv’s own reseller directory, independent merchant reviews on Capterra, and payments-industry analysis of flat rate versus interchange-plus.

The honest limits: Clover does not publish machine-readable prices, so every Clover figure here is a range triangulated across independent resellers and reviewers, and that range is itself one of the findings. G2 and Trustpilot were not available for this comparison, so Capterra is the single independent review source. Exact offline transaction caps are not published by Square or Shopify and are therefore not stated.

Prices current as of September 2026. A large share of published comparisons on this topic come from agencies that resell one of these platforms. My conclusions rest on the pricing and feature evidence above, not on anyone’s partner program.

Clover vs Square vs Shopify: Which One Should You Buy?

For the single-store retailer who wants to start taking payments today with no contract and no monthly fee, Square is the right answer. It is the only one with a free tier, a published rate that is the same for everyone, and nothing to sign.

The routing from there:

Also selling online, or planning to: Shopify, and accept that POS Pro at $89 per location sits on top of an ecommerce plan.
Doing more than roughly $25,000 to $30,000 a month in card volume: get an interchange-plus quote, which in practice means Clover or a similar processor-led setup, and buy the hardware outright rather than leasing it.
Running several locations: Shopify if stock moves between them, Square Premium if each site is largely self-contained.

The cheapest monthly fee and the cheapest business are rarely the same thing. On Clover, the contract matters more than the price. Work out your monthly card volume first, because that single number decides more than any feature list.

Clover vs Square vs Shopify FAQs

Which is cheapest for a single retail store?

Square, on the free plan at $0 per month with 2.6% plus 15 cents in person. Shopify requires an ecommerce plan starting at $39 per month plus $89 for POS Pro. Clover’s cost depends on the reseller, but even its lowest paid tiers start around $15 a month before hardware.

Why do I get different Clover prices from different sellers?

Fiserv distributes Clover through more than 60 certified reseller partners. Each partner sets its own markup, contract terms, and processing model on top of the same underlying Fiserv hardware and platform. That is why two quotes for the same Flex can differ by $150 or more.

Can I keep my Clover hardware if I switch processors?

No. Clover devices are provisioned to Fiserv’s network and cannot be reprogrammed for another processor. Switching means buying new hardware. If the original device was leased, payments on it typically continue regardless.

Do I need a card reader to start?

Not with Square or Shopify. Both accept contactless payments on an unmodified iPhone or Android at the standard in-person rate with no separate reader to buy. Clover does not offer an equivalent phone-only Tap to Pay option that I could confirm.

What does Shopify charge if I do not use Shopify Payments?

A surcharge of 2% on Basic, 1% on Grow, 0.6% on Advanced, and 0.2% on Plus, on top of whatever your third-party gateway charges. The surcharge is waived entirely if you use Shopify Payments.

When is it worth negotiating an interchange-plus rate?

Commonly cited from about $25,000 to $30,000 a month in card volume, especially if your transaction mix is debit-heavy. Below that, flat-rate pricing is usually simpler and competitive. Above it, a well-negotiated interchange-plus account through a Clover reseller can save meaningful money.
