Choosing the right payment system can save you money, reduce headaches at checkout, and keep your customers happy. Two of the most popular options for small retail businesses are PayPal and Square. Both are easy to set up and widely trusted, but they work differently — and the wrong choice for your business model could cost you more than you realize. Here is a straightforward comparison to help you decide.
Fees and Pricing: What You Actually Pay
Both platforms charge a percentage of each transaction, but the details matter. Square charges 2.6% plus $0.10 for in-person card swipes and dips. PayPal’s in-person rate through its Zettle hardware is 2.29% plus $0.09 per transaction, which is slightly lower. For online or keyed-in payments, both platforms charge higher rates — typically around 3.49% — so if you take a lot of transactions that way, compare carefully.
There are no monthly fees on either platform’s basic plan, which is good news if you are just starting out or have irregular sales volume. Square does offer paid plans with added features, but most small retailers do not need them right away.
Hardware and In-Store Setup
Square has a clear advantage here. Its free card reader plugs into a phone or tablet, and its ecosystem of hardware — including the Square Stand, Terminal, and Register — is purpose-built for retail checkout. The point-of-sale software is polished, handles inventory tracking, and works smoothly even when your internet goes down temporarily.
PayPal offers its Zettle card reader for a one-time purchase of around $29. The hardware works well for basic needs, but the retail-focused features are not as deep as Square’s. If you run a busy shop with multiple product types or need strong inventory management, Square is the more capable choice out of the box.
Online Sales and Customer Reach
This is where PayPal stands out. It is one of the most recognized payment brands in the world, and many shoppers feel more confident checking out when they see the PayPal logo. If you sell through your own website or want to add a simple buy button to social media, PayPal’s integrations are broad and familiar to customers.
Square also supports online selling through its own store builder and third-party integrations, but PayPal’s brand recognition gives it an edge when it comes to customer trust at checkout — especially for businesses that do a meaningful share of sales online.
The Bottom Line
If your business is primarily in-person retail and you want reliable hardware, smooth checkout, and built-in inventory tools, Square is likely the better fit. If you sell across multiple channels or want to tap into PayPal’s strong online brand recognition, PayPal deserves a serious look.
The good news: both platforms are free to start. Consider signing up for a trial of each and testing them against your actual sales mix before committing to one long term.
