The short version
- Calculate with statement card volume, not total sales.
- Add every fee before working out the rate.
- Check three months and account for unusual charges.
- Use the same payment mix to compare proposals.
Med spa payments may run through the front desk, booking software, virtual terminal, online store, membership system and financing provider. Their fees won't necessarily share one invoice or statement page.
Calculate the full rate behind the advertised percentage using three statements. Work through a recent medical spa sale with its payment records.

Calculate the full rate from your statement
With the worksheet's example values, med spas would have $76,500 in settled card sales and $2,708 in total fees, giving an effective rate of 3.54%. Enter your own sales and fees from the same statement period.
The advertised percentage is only part of the bill. For a medical spa, use the full processing cost and settled card volume from the same period. Total revenue gives the wrong rate when it includes cash, ACH, checks, financing, insurer money or open invoices.
For med spas, use the right payment totals. Count settled card sales and deposits paid by card only once. Leave out cash, checks, ACH, financing proceeds, insurance payments, gift-card redemptions and uncollected balances.

Med spa: statement audit steps
Follow a recent medical spa sale through this table. It lists the industry's usual handoffs; replace the labels with the documents or screens your team uses.
| Stage | What to verify | Purpose |
|---|---|---|
| Explain at consultation | Before taking money or reserving treatment time, show payment options and written deposit terms. | File the statement audit record here. |
| Connect the treatment payment | Link each payment to the service, package balance, expiration terms and client record. Leave unnecessary clinical details off receipts. | File the statement audit record here. |
| Record membership permission | Get clear permission for recurring charges. Keep enrollment, renewals, cancellations, retries and refunds in the same record. | File the statement audit record here. |
| Reconcile after the visit | Match delivery, product purchases, package use, final receipts, credits, refunds and later disputes to your records. | File the statement audit record here. |
What to save for the statement audit
File these records while you can still trace the sale easily. A refund, cancellation, failed collection or dispute makes missing records much harder to reconstruct.
- The statement's cover page and fee summary
- Deposit report reconciling card volume
- Separate invoices for payment acceptance
- Each month's rate calculation
- Written answers from the provider
What BlueFinch would check for med spas
BlueFinch would use the same medical spa payment mix to compare all proposed percentage charges and fixed fees. Monthly, PCI, gateway, batch, chargeback, software and other account-specific costs may still apply.
BlueFinch currently offers a standalone terminal at no charge, without an equipment lease, long-term contract or cancellation fee. Eligible, configured credit and debit transactions can have a 0% merchant processing rate after review of the state, network, acquirer, written price display and payment channels.
Questions business owners ask
Do I calculate the effective rate using total business revenue?
No. Calculate it with card volume settled through the merchant account. Count settled card sales and deposits paid by card only once. Leave out cash, checks, ACH, financing proceeds, insurance payments, gift-card redemptions and uncollected balances.
How do I handle an annual fee on one month's statement?
List it separately or allocate it consistently over the period you're comparing. Keep it in the calculation, and don't assume an unusual month represents normal costs.
When do med spas need help with the review?
Pause if the statement, written price, customer documents, terminal or receipt disagree. Before the medical spa launches, its processor or acquirer should approve the specific setup.
