Payment processing fees are one of the most misunderstood line items on a practice’s overhead. Most practice owners know roughly what they’re paying, but few can say with confidence why the number looks the way it does, or whether it’s competitive. Because these fees are deducted quietly, they tend to fly under the radar. Left unexamined, those small, incremental costs can chip away at monthly profitability in ways that are easy to overlook and hard to reverse without a closer look.
The Problem: A Confusing Fee Structure
Overall, processing statements aren’t built for clarity. Vague line-item descriptions, bundled pricing, and rates that shift from transaction to transaction make it difficult to know what you’re actually being charged for. While it’s important to note that this variation is legitimate such as different card types, transaction methods, and processing conditions, it’s still difficult to take in without a clear breakdown. Many practice owners can’t tell the difference between a reasonable rate and one that’s simply higher than it needs to be.
Coupled with the time constraints that owners are under and the lack of audit expertise, these numbers can go unchecked for longer than they need.
How Payment Processing Fees Actually Work
To understand where costs come from, it helps to separate the fee structure into its component parts.
Interchange fees are set by the card networks themselves and paid to the issuing bank. These rates are standardized and non-negotiable, regardless of which processor you use.
Processor markups are added on top of interchange, and this is where pricing flexibility, and more important, where profit lives. This is the portion of your rate that varies most from provider to provider.
Pricing models matter too. Flat-rate pricing charges a single, predictable rate across most transactions, while interchange-plus pricing passes through the actual interchange cost, plus a fixed processor markup. Each model has advantages depending on a practice’s transaction mix and priorities, and the right fit depends on your specific volume and patient-payment patterns.
Finally, how a payment is taken matters. Card-present transactions, where a card is physically tapped, inserted, or swiped in the office, are typically priced differently than card-not-present transactions, like phone payments or online portal payments.
Where Dental & Medical Practices Typically Overpay
Every practice’s fee structure looks a little different, but there are common areas worth reviewing closely.
Practices that handle a meaningful share of payments over the phone, through patient portals, or via mailed statements should understand how those card-not-present transactions are priced and confirm they’re structured appropriately for the practice’s actual workflow, since pricing here depends heavily on setup and processor.
Recurring payment plans and financed treatment costs are other areas to watch. These payments are often processed under different rate structures than standard in-office transactions, and the details matter.
Because most practices process significantly lower volume than retail businesses, they also tend to have less natural leverage to negotiate favorable terms, which makes it even more important to understand the components of a rate rather than relying on volume alone.
Pricing structure itself deserves attention too. Whatever model a practice uses, whether flat-rate or interchange-plus, it’s worth periodically confirming that the structure still reflects the practice’s current transaction mix and volume, since the right fit can shift over time.
Beyond pricing model, rates and fees can increase gradually over months or years without any single change feeling significant. Monthly PCI compliance charges or other “junk” fees can add up quietly in the background, adding to the issue.
Finally, manual and unoptimized payment workflows, like re-keying card information or using disconnected systems, can introduce added costs and errors that a more integrated and automated setup would avoid.
How Wellfit Brings Transparency to Payment Processing
At Wellfit, our approach starts with clarity. We believe practices deserve transparent pricing with no hidden markups, and a flat rate that never changes throughout your Wellfit experience.
This transparency means your front office staff doesn’t need to spend extra time and effort steering patients towards in-person payments. No matter how payments are collected, practices can expect the same flat rate pricing and ease of payment every single day.
See What You’re Really Paying
The best way to understand your true cost isn’t to look at your stated rate. It’s to look at what’s actually being withheld.
Here’s a simple way to check: pull 90 days of your processing statements. Add up your total volume of transactions (A) and the total dollar amount withheld from your settlements in fees (B). Divide B by A, and you’ll have your true effective rate, the number that reflects everything you’re paying, not just the rate quoted on paper.
From there, it’s worth understanding what interchange-plus pricing really means for your practice, and whether it, or another model, is the better structural fit for how you take payments.
If you’d like help running these numbers or reviewing your statements, we’re happy to walk through it with you.
