Practices spend more time on the processing rate than on any other number in patient collections, and it is almost never the number that decides the outcome.
Two percent on a balance you captured at the visit beats zero percent on a balance that went to statements, aged for four months, and got written off. The fee is a cost on money you collected. The larger figure is the money you did not.
What does payment processing actually cost a medical practice?
Less than most owners assume as a share of revenue, and more than the headline rate suggests once card mix, transaction size, and failed payments are included. The bigger number is what a practice never collects, and it is rarely measured alongside the processing cost even though the two trade against each other.
Why the headline rate is not your rate
Every processing arrangement quotes a rate. What you actually pay depends on four things underneath it, and practices differ enormously on all four.
Card mix. Debit, credit, and rewards cards carry different interchange costs. A practice whose patients pay mostly by debit runs at a materially lower effective rate than one seeing a lot of premium credit cards, on identical terms.
Average transaction size. Where a per-transaction fee applies on top of a percentage, small balances cost proportionally more. A practice collecting many small copays has a different economic profile from one collecting fewer larger balances.
Card present versus card not present. A card swiped at the desk is priced differently from one keyed over the phone or stored on file.
Failed and retried payments. Declines, retries, and chargebacks all carry cost and none of them appear in the quoted rate.
The number worth knowing is your effective rate. Total processing cost for a period divided by total card volume for the same period. Most practices have never calculated it, and it is the only figure that makes any comparison meaningful.
The number that dwarfs it
Set the effective rate against the collection rate and the argument resolves itself.
A balance collected at the visit arrives in full, minus the processing cost. The same balance deferred to a statement carries staff time, statement production, follow-up calls, a lower recovery rate, and a share that eventually gets written off.
Run those two paths on your own numbers and the difference is not close. The processing cost on a collected balance is a small percentage. The cost of a balance that decays is most of it.
Which is why arguing about a fraction of a percentage point while a meaningful share of patient responsibility goes to statements is optimising the smaller variable.
Is AdvancedMD Pay worth it?
That question cannot be answered generically, and the version of it worth asking is different.
Any integrated payment arrangement trades a processing cost against operational benefit: cards stored securely, payments posting automatically against the correct balance, fewer manual reconciliation steps, and the ability to collect at the moment a balance is known rather than weeks later.
So the evaluation is not rate against rate. It is your effective rate against what the integration changes about when and how much you collect.
Three figures answer it for your practice.
Your effective processing rate, calculated as above. The share of patient responsibility you collect at the time of service. And what a deferred balance costs you across statements, staff time, and write-offs.
A practice collecting most of its patient responsibility at the visit can afford a higher rate comfortably. A practice deferring most of it is paying far more than any processing arrangement charges, in a form that never appears as a fee.
The cost nobody counts
One more figure belongs in the comparison and it appears in no report at all.
Cards on file expire. A card stored eighteen months ago and never revisited stops working, and the practice discovers it when a charge declines, which is after the service, after the balance exists, and often after the patient has moved on.
That failure carries no processing fee. It carries the whole balance.
The patients most likely to hold a stale card are the ones who have not been in recently, which is the same group least likely to respond to a call about money. So the decline rate on stored cards is a real cost of the arrangement and it sits entirely outside the rate you were comparing.
It is also the cheapest thing on this page to fix. A list of cards expiring in the next sixty days is a date comparison against data you already hold.
Building the visibility on your AdvancedMD data
Three views make the whole comparison possible, and all three draw on records already being kept.
Effective rate by period. Processing cost against card volume, monthly, so the trend is visible rather than the quoted number.
Time of service collection share. Patient responsibility collected at the visit against total patient responsibility for the period. This is the figure that predicts everything downstream.
Stored cards approaching expiry. A rolling sixty day window, with the balance at risk behind each one.
None of that is a reporting project. It is deciding that payment economics deserve a standing view rather than an annual conversation about a rate.
What this means for you
Calculate your effective rate for one closed month. Then calculate what share of patient responsibility you collected at the visit.
If the second number is high, the first one barely matters and you can stop thinking about it. If the second number is low, you are already paying far more than any processing arrangement charges, and it is being paid in write-offs and staff hours rather than in fees.

Questions people ask
What does payment processing actually cost a medical practice?
Less than most owners assume as a share of revenue, and more than the headline rate suggests once card mix, transaction size, and failed payments are included. Calculate your effective rate: total processing cost divided by total card volume for the same period.
Why is my effective rate higher than the rate I was quoted?
Four things sit underneath the headline. Card mix, since debit and premium credit carry different interchange. Average transaction size, where a per-transaction fee applies. Card present versus keyed. And declines, retries, and chargebacks, none of which appear in the quote.
Is an integrated payment arrangement worth the fee?
It depends on what it changes about when you collect. Three figures answer it: your effective rate, the share of patient responsibility you collect at the time of service, and what a deferred balance costs across statements, staff time, and write-offs.
What is the biggest cost in patient payments?
What you never collect. A balance deferred to a statement carries staff time, follow-up, a lower recovery rate, and a share that gets written off. The processing cost on a collected balance is a small percentage. A decayed balance is most of the money.
Do expired cards on file cost anything?
The whole balance, and no fee. A stored card that expires stops working silently, and the practice finds out when a charge declines after the service. A rolling sixty day expiry list is a date comparison against data you already hold.
