The quick answer

Use Stripe for your Shopify store, custom e-commerce site, or digital product sales when you want full control and low fees. Choose Square if your online store also has a physical pop-up shop or market stall, as its online store and POS integrate seamlessly. Use PayPal for Etsy or other marketplaces where buyers expect it, or as a secondary option on your own site to boost buyer trust.

Side-by-side breakdown

Stripe charges 2.9% + $0.30 per online sale. It has no monthly fees and connects directly with Shopify, WooCommerce, BigCommerce, and most custom e-commerce platforms. It's best for selling digital products, subscriptions (like a monthly craft box), or physical goods directly from your site. It also handles international payments well, which is key for global online sellers.

Square charges 2.9% + $0.30 for online sales. While known for in-person, its free online store and payment processing are a simple choice for small online businesses, especially those who might also do pop-up markets. It helps you manage online and offline inventory in one place, which is handy for Etsy sellers expanding.

PayPal charges 3.49% + $0.49 for standard online checkouts. This makes it more expensive for direct sales than Stripe. However, many online buyers, especially on marketplaces like Etsy or when buying from a new brand, trust the PayPal button. It's a good secondary checkout option to reduce abandoned carts on your Shopify store.

When to choose Stripe

Choose Stripe if you run a Shopify store, sell digital products (eBooks, courses), or offer subscriptions (membership site, monthly product boxes). It integrates perfectly with major e-commerce platforms like Shopify, WooCommerce, and Squarespace. Stripe also offers robust tools like Radar for fraud protection, crucial for online sellers who face chargebacks, and handles international payments seamlessly, allowing you to sell worldwide.

When to choose Square

Choose Square if your online store is your main business, but you also plan to sell at craft fairs, pop-up shops, or local markets. Square's free online store works well for beginners and its point-of-sale (POS) system makes it easy to manage both online and in-person inventory and sales. It's a great option for an Etsy seller wanting to start their own site and handle occasional physical sales without separate systems.

When to choose PayPal

Use PayPal as a secondary payment option on your Shopify store or custom site. Many online shoppers, especially those who are new to your brand or shop internationally, feel safer checking out with PayPal. It’s also often the default or preferred choice on marketplaces like Etsy or eBay. However, its higher fees (3.49% + $0.49 per transaction) mean it shouldn't be your only option. Offer it alongside Stripe or Square to capture more sales from hesitant buyers.

The verdict

For most e-commerce businesses — whether you're starting a Shopify store, selling on your own website, or moving from Etsy to your own platform — Stripe is the best choice. It offers the lowest direct online fees and the best tools for growth. Consider Square if your online sales also involve regular pop-up shops or market stalls. Always add PayPal as a second option to catch buyers who prefer it, but don't rely on it due to higher fees for direct sales. Set up Stripe first, link it to your e-commerce platform, and focus on selling.

How to get started

Setting up Stripe for your online store is straightforward. Create an account, verify your business (this includes providing an EIN or Social Security Number), and connect your bank account. Then, link Stripe directly to your e-commerce platform (Shopify, WooCommerce, BigCommerce). If you're just starting and don't have a full website yet, use Stripe Payment Links to send direct invoices or sell a single product. These links convert better than asking for bank transfers in an email and get you paid instantly for pre-orders or custom requests.
