Private Healthcare Payment Processor Fees: What Your MedSpa or Clinic REALLY Pays

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.
