START WITH YOUR BUYING BRIEF

Which workflow fits your team?

Consider PayPal when its selected Checkout or Expanded Checkout integration and separate POS offering fit your selling channels. Consider Square when its payments and selected business software fit the day-to-day shop, restaurant or service workflow. Compare a complete online or in-person operating brief: a PayPal button and a Square POS subscription are different scopes.

Counter sale

Can the proposed POS record the intended product and payment?

PayPal: Inspect the selected PayPal POS and supported device in a permitted demonstration.

Square: Inspect the selected Square software and supported device in a permitted demonstration.

The sale, item and operator record match the required shop workflow.

Web order

Can the ecommerce platform use the required checkout route?

PayPal: Check the current PayPal integration and Checkout product.

Square: Check the current Square integration and online payment route.

The intended platform, method and order confirmation are supported.

Return workflow

Can staff connect a return to the original payment?

PayPal: Inspect a controlled POS or test-order refund demonstration.

Square: Inspect the equivalent controlled demonstration.

Authorised roles can explain the return, refund and inventory effect.

Complete cost

Does the quote reflect the actual selling channels?

PayPal: Include online and POS fees, devices and optional services.

Square: Include route-specific fees, devices and paid software.

No required hardware, processing route or software tier is omitted.

Compare the same selling channel first

Start by separating counter sales, ecommerce orders, payment links and invoices. Each channel can have its own integration, device, operator and charging rules. Write the relative need for each channel before treating two familiar payment brands as identical business systems.

PayPal distinguishes its online Checkout products from its POS service. Square combines payments with general and sector-specific software. For each vendor, inspect the exact product that would be retained and the connection to the existing store or order system.

A free app is only one part of the budget

Square’s UK Free plan has no monthly software fee, but transactions still incur processing charges. A PayPal account signup or free POS app download also does not remove live processing costs. Count devices, required software capabilities and the payment routes used by the business.

Use controlled demonstrations or official test environments for the evaluation. Do not collect real customer card details for a comparison. This page does not report completed POS testing, a conversion result or a universal lower-cost provider.

Questions before you choose

Is Square Free free payment processing?

No. It is a software plan with no monthly software charge. Processing fees still apply, and hardware or optional paid tools can add costs.

Is PayPal POS still called Zettle?

The reviewed UK page says Zettle is now PayPal Point of Sale. It is a separate scope from choosing an online PayPal Checkout integration.

Can any card reader be used with either service?

Do not assume that. Check the supported device, application, region and payment infrastructure for the selected service.
