The quick answer for fitness professionals
For independent fitness pros: Choose Stripe if you primarily book clients online, offer recurring memberships (like monthly coaching packages or unlimited class passes), or sell digital workout plans. It works well with many booking platforms. Choose Square if you take payments face-to-face for sessions at a studio, client homes, or outdoor boot camps, and might also sell a few small retail items. Use PayPal for quick, one-off invoices or as an extra checkout option, especially for clients who already prefer it.
Side-by-side breakdown for fitness businesses
**Stripe:** Handles both online payments for your website and in-person payments. Its tools are great for setting up custom checkout pages for your 1-on-1 coaching packages, recurring memberships for online yoga classes, or selling multi-session packs. You can link it to popular fitness booking software like Acuity Scheduling or Mindbody. Fees are typically 2.9% + 30 cents for online card transactions. No monthly fees. You usually get your money in 2 business days.
**Square:** Made for businesses that take payments in person. It offers a free card reader for your phone or tablet, which is perfect for swiping cards after a personal training session, taking payment for a drop-in Pilates class, or at a pop-up boot camp. Its app can also track sales of small items like branded t-shirts or resistance bands. In-person card fees are 2.6% + 10 cents. No monthly fees on the basic plan. Payouts are often next business day.
**PayPal:** Many clients recognize and trust PayPal. It's a simple way to send invoices or offer a quick payment button. Use it if your clients expect it, especially for fast invoicing for a one-off consultation or from international clients. Its standard fees are higher at 3.49% + 49 cents for most online transactions. Be aware that PayPal sometimes puts holds on money for new or unusual transactions, which can delay you getting paid.
When to choose Stripe for your fitness practice
Choose Stripe if most of your fitness business happens online. This includes virtual coaching, selling digital workout plans, or streaming on-demand classes. It's ideal for setting up recurring billing for monthly coaching memberships, weekly Pilates subscriptions, or selling discounted class packs directly from your website. Stripe integrates smoothly with many online booking systems like Calendly, Acuity, or simply by adding payment links to your own site. Even if you're not tech-savvy, you can easily create custom payment links for a single session or invoices for a corporate wellness gig.
When to choose Square for in-person training
Pick Square when you take payments primarily in person. This could be after a personal training session at a client's home, at a rented studio, or for drop-in fees at a park boot camp or pop-up yoga event. Square offers a free card reader that plugs into your phone or tablet, making it easy to swipe or tap cards on the spot. Its point-of-sale (POS) app can also help you track and sell small items like protein bars, resistance bands, or branded water bottles. While Square has online payment features and scheduling, its strongest suit is making in-person transactions smooth and professional.
When to choose PayPal as a secondary option
Think of PayPal as a backup payment option, not your main one. Many clients, especially those new to your business or buying a single session, might already have a PayPal account and prefer to use it for speed and familiarity. It’s useful for sending quick invoices for a last-minute consultation or for clients living outside your country. However, PayPal's fees can be higher, and it’s known for sometimes holding funds, especially for new accounts or larger transactions, which can delay you getting access to your earnings. So, offer it as a choice, but rely on Stripe or Square for your core business.
The verdict for fitness pros
Here’s the simple truth for fitness professionals: If you primarily offer online coaching, virtual classes, or recurring memberships, Stripe is likely your best bet. If you mostly train clients face-to-face, run pop-up classes, or visit client homes, Square offers the best tools for in-person payments. Always consider adding PayPal as an extra payment method for clients who prefer it, but don't make it your main system due to its fees and potential delays.
