Stripe vs Square vs PayPal: Best Payment Processor for Private Healthcare & MedSpa Practices
Every patient payment, from a co-pay to a monthly wellness membership, needs a reliable payment processor. Picking the wrong one can mean higher fees, slower payments, or missing features like online booking integration that are vital for private healthcare and MedSpa practices. Stripe, Square, and PayPal are top choices for clinics run by nurse practitioners, functional medicine doctors, and physical therapists. Here's which one fits your specific practice and why.

The quick answer
Use Stripe if your private practice or MedSpa relies on online booking, telehealth services, selling digital wellness products, or offering DPC memberships with recurring payments. It integrates well with most patient portals and EMR systems. Use Square if most patient payments happen in-person at your clinic and you need integrated point-of-sale (POS) hardware for co-pays or service fees. Use PayPal as a secondary payment option when specific patients request it or for international telehealth consultations, but avoid it as your primary system due to higher fees.
Side-by-side breakdown
Stripe charges 2.9% + $0.30 for online patient payments. This is the standard for credit card processing for your online booking system deposits, virtual consultations, or when patients pay their invoice online. It has no monthly fees, no contracts, and offers the most flexible tools for integration with clinic management software. It's excellent for managing recurring DPC memberships, ongoing wellness programs, and detailed patient invoicing.
Square charges 2.6% + $0.10 for in-person payments (e.g., swiping a patient's card at your front desk for a co-pay or aesthetic treatment) and 2.9% + $0.30 for online payments (like online booking deposits). Its hardware ecosystem, including card readers, terminals, and registers, is user-friendly for a physical clinic setting. Square also offers a free POS app, basic inventory management for supplements or medical-grade skincare, and built-in appointment booking.
PayPal typically charges around 3.49% + $0.49 per transaction for standard online patient payments. This is generally higher than Stripe or Square for most transactions. While more expensive, many patients, especially older demographics or those making international payments for telehealth services, have existing trust in PayPal. It can be a useful secondary checkout option on your patient portal or invoice for those who prefer not to enter card details directly.
When to choose Stripe
Choose Stripe if your private practice or MedSpa is online-first or relies heavily on online patient payments. This includes deposits for online booking systems like JaneApp or Acuity Scheduling, telehealth services, selling digital wellness courses, or managing recurring payments for DPC memberships and monthly wellness plans. Stripe's subscription management is top-tier, making it easy to bill patients automatically for ongoing care or product subscriptions (like custom supplement protocols). If you use a sophisticated patient portal or EMR and want to embed payment options directly for a seamless patient experience, Stripe offers the best tools for integration and customization.
When to choose Square
Choose Square when most patient payments at your private practice or MedSpa happen in person. This applies to physical therapy clinics, chiropractic offices, or MedSpas offering aesthetic treatments where patients pay at the front desk. Square's user-friendly hardware, like their handheld Square Reader for contactless and chip cards or the Square Terminal, is perfect for accepting co-pays, deductibles, or full service fees quickly. Its free POS app can also track inventory for any supplements, medical supplies, or medical-grade skincare products you sell, and it includes basic appointment scheduling, which is useful for smaller practices starting out.
When to choose PayPal
Consider PayPal as a secondary payment option for your private practice, not your main system. It can be useful for older patients who are more familiar with it, or for international patients paying for virtual consultations for functional medicine. PayPal handles currency conversions for global payments, which can be a plus for practices with patients abroad. However, its higher fees (around 3.49% + $0.49 per transaction) and less seamless integration with modern clinic management software make it less ideal as your primary payment method. Only add it if your patient demographic specifically requests it.
The verdict
For private healthcare and MedSpa practices focused on online booking, telehealth, and recurring patient memberships: Stripe is generally the best choice for its robust online features and integration capabilities. For practices where most payments are in-person, like a physical clinic or aesthetic center with a front desk, Square is usually the simplest solution with its easy-to-use POS hardware. Add PayPal as a backup option on your patient portal if your conversion data shows specific patient groups abandoning payments due to lack of a trusted alternative. For many new practices, Stripe is the easiest to set up for online payments and integrates well with common clinic software, letting you focus on patient care instead of payment headaches.
How to get started
To get started with Stripe for your practice: Sign up for an account, provide your clinic's legal and banking details for verification, then enable the features you need. Use Payment Links for quick one-off patient payments (like a deposit for a new patient visit, a lab fee, or a supplement purchase). Use Stripe Billing for managing recurring memberships for your DPC model or ongoing wellness programs. Stripe Invoicing can handle out-of-pocket patient billing for specific services. Sending a secure payment link for a consultation fee or program enrollment is much more professional than giving out bank transfer details and helps you get paid instantly, improving patient experience and your cash flow.
