Here’s a direct comparison tailored for nurse practitioners, functional medicine doctors, and physical therapists launching their boutique practices.

The quick answer

Use Stripe if you offer online booking, telehealth services, membership programs, or subscription wellness plans that need flexible online payments and patient portals. Use Square if your practice takes most payments in person at the clinic, sells supplements or skincare products, and needs a simple point-of-sale (POS) system with integrated appointment scheduling. Use PayPal as an extra option for patients who prefer it, especially for online deposits or invoice payments, but it shouldn't be your main system due to potential holds on funds.

Side-by-side breakdown

Stripe processes patient payments online and sometimes in person. Its system is powerful for custom patient portals, managing recurring subscription wellness plans, and processing international patient payments if you have them. Standard fees: 2.9% + 30 cents per card transaction. No monthly fees. Payouts in 2 business days usually. Excellent for integrating with practice management software. Square is built for in-person clinic payments and retail sales. Its free card readers, Square Register or Terminal devices, and integrated appointment scheduling make it a strong choice for physical therapy clinics, functional medicine offices selling nutraceuticals, or medspas with retail skincare products. In-person: 2.6% + 10 cents. No monthly fees on the basic plan. PayPal is the most recognized online payment name for patients. Many specifically look for the PayPal button for convenience. Fees: 3.49% + 49 cents for standard online payments, 2.99% + 49 cents for checkout. New practices might see holds on funds, which can delay access to your money and impact cash flow.

When to choose Stripe

Choose Stripe if your private practice focuses heavily on online patient engagement. This includes setting up patient portals, offering telehealth consultations, selling online wellness programs, or managing recurring monthly membership fees for functional medicine patients. Stripe's tools are ideal for creating custom patient intake forms with payment, handling direct-to-patient product shipments, or integrating with specialized healthcare platforms that need powerful payment APIs. Even without a tech background, you can use Stripe's ready-made payment links for patient invoices or build simple checkout pages for services.

When to choose Square

Pick Square when your private practice or medspa primarily takes payments in person at the front desk. This is perfect for physical therapy clinics handling co-pays, nurse practitioner offices, or medspas selling retail products like injectables, supplements, or skincare lines. Square's free card readers (like the Square Reader for chip cards or the Square Terminal for a full POS experience), appointment scheduling, and basic inventory management for your retail items create a smooth, integrated system. It handles online payments too, but its biggest strengths are in managing the patient experience at your physical location, making check-out easy and professional.

When to choose PayPal

Add PayPal as an additional checkout option alongside your main payment processor, especially for online patient payments or deposits. A significant number of patients appreciate having PayPal as an option and might specifically look for it when paying for services or booking appointments online. Use it as a secondary choice, not your primary system, because its fee structure can be less clear, and new accounts sometimes experience fund holds. For a small private practice or medspa, unpredictable access to your funds can be challenging.

The verdict

For private healthcare practices and medspas that focus on online patient services, recurring memberships, or telehealth: Stripe. For clinics and medspas that primarily see patients in person, handle co-pays at the front desk, or sell retail products: Square. Always offer PayPal as a supplemental online payment option for patient convenience, but don't rely on it as your main system. If you integrate with specific practice management software, check which payment processors it pairs best with to streamline your operations.

How to get started

To use Stripe, set up an account and create a patient payment link for invoices or a subscription plan in under 10 minutes – no coding needed. For Square, order a free Square card reader for your front desk and install the POS app on a tablet or smartphone. You can also explore the Square Terminal for a more robust in-clinic solution. Both platforms typically offer fast account approval for most private healthcare practices and medspas, letting you start accepting patient payments quickly.
