Stripe vs Square: Features Compared
Core Features
Stripe is a payment gateway and API platform. You integrate it into your website, app, or platform using code — there is no standalone POS app and no off-the-shelf checkout screen for a shop counter. When we tested Stripe’s integration process, what stood out was the flexibility: accept cards, direct debits, open banking, Klarna, and Clearpay through one integration.
Square is a POS platform that happens to include online payments. You download the app, plug in a card reader, and start taking payments. Free inventory tracking, sales reporting, customer profiles, and multi-location management are included without a monthly fee. If your business needs a till system and a payment processor in one, Square does that. Stripe does not.
Products and Services
Stripe’s product range targets developers and platforms. Stripe Billing handles recurring subscriptions at 0.5% of recurring charges. Stripe Connect powers marketplace payment flows — if you run a platform where buyers pay sellers, Connect manages the splits, payouts, and compliance. Payment Links let you create no-code payment pages for one-off sales without building a full checkout.
Square’s product range targets merchants. You get purpose-built POS apps for restaurants (table management, kitchen display), retail (barcode scanning, purchase orders), and appointments (booking, deposits, no-show protection). Each vertical app is free on its base tier. Square Online gives you a free website builder with integrated payment processing — functional enough for a small business that does not want to pay for Shopify or WooCommerce.
Integrations and Tools
Stripe offers 700+ integrations and SDKs for Python, Ruby, PHP, Java, Node.js, Go, and .NET. If you build your checkout, you control every step — from the payment form to the confirmation page. Stripe Elements lets you embed pre-built payment components, and Stripe Checkout offers a hosted payment page if you want to skip the custom build.
Square connects to Xero and QuickBooks on its free plan. Your card sales sync with accounting software automatically. Hospitality businesses get delivery platform integrations — Deliveroo, Uber Eats, and Just Eat via Deliverect. We verified both providers’ integration lists in April 2026. Stripe’s integration strength is depth and flexibility; Square’s is convenience and zero-setup accounting.
Scalability
Stripe scales through its API. As your transaction volume grows, you can negotiate custom pricing, add fraud rules, build complex payment flows, and handle multi-currency settlement across 135+ currencies. Stripe is the payment infrastructure behind Shopify, Deliveroo, and Monzo — it handles enterprise-scale volume without you outgrowing the platform.
Square scales through its software tiers. Plus plans (£29–£69 per location per month) reduce your transaction fee to 1.6% and add features like advanced reporting, team permissions, and loyalty programmes. Custom pricing is available above £200,000 annual card turnover. If you are opening a second location, Square’s multi-site management is already built in. Stripe would require you to build that yourself.
Stripe vs Square: Fees and Pricing Compared
Pricing Structure
Neither Stripe nor Square charges a monthly fee, setup fee, or cancellation fee on its standard plan. You pay per transaction only. Stripe charges 1.5% + 20p for UK card payments. Square charges 1.75% for in-person payments and 1.4% + 25p for online UK card payments.
The structural difference: Stripe adds a flat 20p to every transaction. Square uses a percentage-only model for in-person payments. On small transactions under £20, that 20p adds up. On a £5 contactless sale, Stripe costs 27.5p (5.5% effective rate) while Square costs 8.75p (1.75%). If your average transaction is small, Square’s percentage-only pricing costs you less per sale.
Transaction and Usage Fees
For online UK card payments, the two are closer than you might expect. On a £50 sale: Stripe charges 95p (1.5% + 20p), Square charges 95p (1.4% + 25p). Identical. On a £100 sale: Stripe charges £1.70, Square charges £1.65. The gap only opens meaningfully on high-value transactions — at £500, Stripe costs £7.70 vs Square’s £7.25.
International cards widen the gap. Stripe charges 3.25% + 20p for international cards. Square charges 2.5% + 25p for non-UK cards. If your customers frequently pay with non-UK cards — a common pattern for e-commerce businesses selling internationally — Square is cheaper per transaction on international volume.
Additional Costs
Settlement speed is where Stripe costs you indirectly. We confirmed that Square settles next business day for free. Stripe’s default settlement is T+3 business days — your money from Monday’s sales arrives on Thursday. Stripe offers instant payouts within 30 minutes for a 1% fee. Square offers instant settlement for 1.5%. If you need your cash flow moving daily, Square’s free next-day settlement avoids a cost Stripe would charge.
Hardware costs differ sharply. Square’s Reader starts at £19 ex VAT — the cheapest branded card reader on the market. Stripe’s WisePad 3 costs £49, and the Reader S700 costs £229. Stripe also charges £7/month per reader for fleet management. If you need in-person payment hardware, Square is substantially cheaper to get started.
| Cost | Stripe | Square |
|---|---|---|
| Online fee (UK cards) | 1.5% + 20p | 1.4% + 25p |
| In-person fee | 1.5% + 20p (via Terminal) | 1.75% |
| International card fee | 3.25% + 20p | 2.5% + 25p |
| Monthly fee | £0 | £0 |
| Cheapest card reader | WisePad 3 £49 ex VAT | Reader £19 ex VAT |
| Settlement speed | T+3 default (instant 1%) | Next business day (instant 1.5%) |
| Contract | None | None |
Stripe vs Square: Ease of Use and Setup Compared
Onboarding Process
Square is ready in minutes. Download the app, verify your identity, and start accepting card payments with Tap to Pay on your phone. No developer, no website, no integration. Your first sale can happen the same afternoon you sign up.
Stripe requires integration work before you process a single payment. If you use a platform like Shopify, WooCommerce, or Squarespace, you can activate Stripe through their built-in payment settings — no coding needed. If you are building a custom checkout, expect hours to days of developer time depending on complexity. Stripe’s Payment Links offer a no-code workaround for simple sales, but they are not a full checkout.
Day-to-Day Usability
Square’s POS app is designed for shop-floor staff. We found that item buttons, quick-sale keys, split payment options, and tip prompts are all accessible without training beyond a brief walkthrough. If you hire seasonal staff or have high turnover, that simplicity saves you onboarding time every month.
Stripe’s Dashboard is designed for business owners and developers monitoring payment flows. You see transaction logs, dispute management, subscription analytics, and fraud screening results. It is powerful for oversight but useless as a point-of-sale interface. If you need someone behind a counter to take payments, Stripe does not give them a screen to work with.
Stripe vs Square: Customer Reviews and Ratings Compared
Stripe’s most frequent negative reviews cite account holds and sudden fund freezes, particularly for businesses in industries Stripe considers higher-risk. If your business model involves pre-orders, high-value transactions, or unfamiliar categories, factor in the risk that Stripe may hold funds while reviewing your account.
Square’s recurring complaint is similar: account holds and payment delays, especially in the first weeks of processing. New businesses with no transaction history are most likely to trigger automated risk reviews. We recommend starting with a small volume of transactions and building history before relying on either provider for large payments.
Stripe vs Square: Customer Support Compared
Stripe’s support model is developer-first. Documentation is detailed and well-organised — most integration problems can be solved from the docs alone. For account-level issues, Stripe offers email and chat support, but response times vary and there is no guaranteed SLA on the standard plan. We checked Stripe’s advertised support channels in April 2026.
Square offers phone and email support alongside an online help centre and community forum. Neither provider gives you a dedicated account manager on the free tier. The practical difference: if your card reader goes down during Saturday lunchtime trade, you need fast resolution. Neither provider guarantees same-day support on its standard plan — a risk you should factor into your contingency planning.
Stripe vs Square: Payment Security and Compliance Compared
We confirmed that both Stripe and Square are PCI DSS Level 1 compliant — the highest level of payment card industry security certification. You do not need to manage PCI compliance yourself when using either provider. They handle encryption, tokenisation, and secure card data storage as the payment facilitator.
Stripe includes Radar, its machine-learning fraud prevention tool, at no extra cost. Radar analyses transaction patterns and blocks suspicious payments before they complete. Square does not offer an equivalent built-in ML fraud tool on its standard plan. If your business processes online payments where card-not-present fraud is a risk, Stripe’s included fraud prevention is a meaningful advantage you would otherwise need to buy separately.
Stripe vs Square: Pros and Cons Compared
Stripe’s advantage is flexibility and power. You get the most capable payment API in the UK, competitive online fees at 1.5% + 20p, ML fraud prevention included free, and subscription billing at 0.5% of recurring charges. The trade-off: you need developer resources to integrate, there is no standalone POS app, hardware is expensive, and default settlement takes three business days.
Square’s advantage is completeness without complexity. Free POS software with inventory and reporting, a card reader from £19, free online store and invoicing, and next-day settlement at no charge. The trade-off: the in-person fee is higher at 1.75%, Plus plans cost £29–£69 per location for advanced features, and you cannot build custom payment flows or run marketplace payment routing through Square’s standard platform.
Who Should Choose Stripe vs Square
Choose Stripe if your business operates primarily online and you have access to a developer — even a freelancer for the initial setup. SaaS companies collecting subscriptions, e-commerce stores on Shopify or WooCommerce, and platforms connecting buyers with sellers all benefit from Stripe’s API depth. Stripe is not the right fit if you need a card reader on a shop counter tomorrow with no technical setup.
Choose Square if your business takes payments in person, needs POS software, or sells through multiple channels without a development team. Café owners, retail shops, mobile service providers, and appointment-based businesses get a working payment system on the same day they sign up. Square is not the right fit if your payment flows require custom logic, recurring billing beyond basic invoicing, or marketplace payout splits.
Some businesses need both. A restaurant using Square POS in the dining room might use Stripe for online orders through a custom website. A retailer running Square in-store might use Stripe for subscription boxes sold online. The platforms are not mutually exclusive — but managing two payment providers adds reconciliation complexity you should account for.
Alternatives to Stripe and Square
Zettle by PayPal charges 1.75% per in-person transaction with a reader at £29 ex VAT — the same rate as Square with PayPal ecosystem integration built in. SumUp charges 1.69% per in-person transaction with a reader from £25 ex VAT, making it the cheapest pay-as-you-go card reader option if you only need in-person payments.
PayPal Commerce Platform is an alternative to Stripe for online payments if your customers prefer paying via their PayPal balance. Dojo offers fixed-rate card machines with next-day settlement but requires a contract. We compared all major UK payment providers in our best card machines and best payment gateways guides.
Final Verdict: Stripe vs Square for Your Business
Stripe is the better payment platform for online businesses with developer resources: competitive fees, the most flexible API, included fraud prevention, and subscription billing. Square is the better payment platform for in-person and omnichannel businesses: free POS software, cheap hardware, next-day settlement, and zero technical setup required.
Your decision comes down to where your customers pay and whether you have someone who can write code. If the answer is “online” and “yes”, Stripe. If the answer is “in person” or “no developer”, Square. If the answer is “both channels”, Square handles the broader range out of the box — unless your online payment needs demand the customisation that only Stripe’s API provides.

Stripe vs Square FAQs
Can you use Stripe without a developer?
Partially. If you use Shopify, WooCommerce, Squarespace, or another platform with a built-in Stripe integration, you can activate Stripe through their payment settings without writing code. Stripe Payment Links also let you create simple payment pages with no technical setup. For custom checkouts, subscription logic, or marketplace payment flows, you need a developer.

Can you use both Stripe and Square for the same business?
Yes. Many businesses use Square for in-person POS payments and Stripe for online transactions.

Square becomes marginally cheaper on larger transactions. For international cards, Square charges 2.5% + 25p vs Stripe’s 3.25% + 20p — a meaningful gap if you sell to overseas customers.

Square provides standard fraud monitoring but does not offer an equivalent ML-powered tool on its standard plan. For businesses processing online payments where card-not-present fraud is a concern, Stripe’s included fraud prevention is the more advanced option.
