Private Healthcare Payment Processor Fees: What Your MedSpa or Clinic REALLY Pays
Opening a private healthcare practice, MedSpa, or functional medicine clinic means managing every cost. Payment processor fees are often overlooked, but they add up. The rate advertised is rarely what you actually pay once you factor in specific card types (like HSA/FSA), in-person versus online payments, chargebacks, and monthly service fees. This guide gives you a plain-language comparison of what your clinic will actually pay on each major platform.

The quick answer
For most private healthcare clinics and MedSpas processing under $75,000/month, Stripe and Square offer straightforward fee structures. These work well for both online patient portals/booking and in-person clinic visits. If your practice uses a specific electronic health record (EHR) or practice management system, first check if they have a preferred or integrated payment processor. This can simplify operations and ensure better data flow, sometimes at a slightly higher fee.
Side-by-side breakdown
Here’s how common payment processors stack up for your practice:
Stripe: 2.9% + 30 cents (card not present). 2.7% + 5 cents (in-person). Interchange-plus pricing might be available for higher-volume practices. No monthly fee. Chargeback fee: $15 (refunded if you win). Best for online bookings, patient portals, telehealth payments, and subscription-based membership models common in functional medicine or physical therapy. Supports HSA/FSA cards.
Square: 2.6% + 10 cents (in-person). 2.9% + 30 cents (online). No monthly fee on standard plan. First card reader is often free. Square is excellent for in-person payments at the front desk using their terminals (like Square Register or Terminal), especially if your MedSpa also sells retail products like skincare or supplements. Their online tools also work for basic online booking and invoicing. Supports HSA/FSA cards.
PayPal: 3.49% + 49 cents (standard checkout). 2.99% + 49 cents (advanced checkout). Fees are higher and the structure is more complex. While some patients trust PayPal, it's less common for primary patient payments in a clinical setting due to higher costs and less seamless integration with most practice management software.
Wave Payments: 2.9% + 60 cents (card). 1% (bank transfer, minimum $1). No monthly fee. Built into free Wave accounting software. This can be a cost-effective option for solo practitioners or smaller clinics just starting out, especially for accepting credit cards and bank transfers for invoices with integrated bookkeeping.
When lower fees matter most
For private healthcare practices, fee optimization matters most when your average patient visit value is high, or your practice has a high volume of transactions. A $250 physical therapy session, a $400 functional medicine consultation, or a $700 MedSpa treatment means processing fees are a larger dollar amount per transaction. At $15,000/month in patient revenue, a 0.3% fee difference is $45 – noticeable. At $150,000/month, that difference becomes $450 – a significant saving worth discussing with your processor or considering a switch. This is especially true if a large portion of your payments come from standard credit cards rather than HSA/FSA cards, which sometimes have slightly different rates.
When to prioritize features over fees
Prioritize features when patient experience, data security, and operational efficiency are critical. This means choosing a processor that integrates smoothly with your EHR/EMR system, offers automated payment plans for larger treatment packages, or provides robust tools for recurring billing if you have membership models. For example, a processor that easily handles HSA/FSA payments, provides clear patient statements, and allows for patient self-pay options can improve compliance and reduce administrative burden. Also, consider HIPAA compliance; while all payment processors handle PCI compliance for card data, ensure any integration with your patient portal or EHR maintains HIPAA standards. A slightly higher fee is often worth a smoother workflow and better patient trust.
The verdict
For most private healthcare practices and MedSpas, start by looking at Stripe for online booking and membership payments, and Square for in-person clinic payments. Both are reliable and integrate with many common practice management tools. If your electronic health record (EHR) system has a built-in payment solution, start there to streamline your operations, even if the rate is slightly higher. Revisit your processor choice at $75,000/month in revenue when negotiated rates and interchange-plus pricing might offer significant savings.
How to get started
Calculate your clinic's current effective processing rate: total fees paid last month divided by total patient revenue. Compare this to the published rates above. If your private practice or MedSpa is paying above 3.2% without getting robust EHR integration, patient financing options, or seamless HSA/FSA card acceptance, you likely have room to optimize. If you're not yet processing payments, begin with Stripe or Square for their ease of use – you can always switch or negotiate better rates as your practice grows.

FREQUENTLY ASKED QUESTIONS
Are there hidden fees I should watch for?
Yes. Watch for: chargeback fees ($15-25 per dispute), international card surcharges (1.5% additional on Stripe), currency conversion fees, refund fees (Stripe keeps the processing fee on refunds), and ACH/bank transfer fees which vary by processor.
Can I negotiate lower rates?
Yes, once you are processing over $50,000/month consistently. Contact Stripe, Square, or PayPal directly and ask about custom pricing or interchange-plus. Most processors will negotiate rather than lose a high-volume account.
