The short version
- Use card volume from the merchant statement, not total sales.
- Count the full bill before calculating the rate.
- Review three months and explain unusual charges.
- Compare proposals against the same payment mix.
Medical spa payments often pass through the front desk, booking software, virtual terminal, online store, membership system, and financing provider. The fees may not appear on one page or invoice.
A three-statement worksheet for finding the real rate behind a processor's advertised percentage. For this review, use one recent medical spa sale and the payment record that followed it.

Med Spas Effective-Rate Worksheet
Enter one statement period. Nothing is saved or sent.
- Settled card volume: example input 76500
- Complete processing fees: example input 2708
Open the live page to change the inputs. The calculation stays in the browser and uses only the values entered.
Rebuild the rate from the statement
Using the default worksheet values, med spas with $76,500 in settled card sales and $2,708 in complete fees would calculate an effective rate of 3.54%. Replace both figures with numbers from the same statement period.
The advertised percentage is one line in a larger bill. A medical spa needs the complete processing cost and the settled card volume from the same period. Dividing by total revenue gives a false answer when cash, ACH, checks, financing, insurer money, or open invoices are mixed in.
For med spas, the boundary matters. Include settled card sales and card deposits once. Exclude cash, checks, ACH, financing proceeds, insurance payments, gift-card redemptions, and balances that have not been collected.

Med Spas statement audit workflow
Run the review through one recent medical spa transaction. The table follows the industry's normal handoffs, but the team should replace each label with the document or screen it uses.
| Decision point | What to check | Why it matters |
|---|---|---|
| Consultation | Show the payment choices and written deposit terms before collecting money or reserving treatment time. | Attach the statement audit record at this stage. |
| Treatment or package | Tie every payment to the named service, package balance, expiration terms, and client record without placing unnecessary clinical detail on a receipt. | Attach the statement audit record at this stage. |
| Membership | Obtain clear recurring-payment permission and keep enrollment, renewal, cancellation, retry, and refund records together. | Attach the statement audit record at this stage. |

Records for the statement audit
Save these records while the transaction is still easy to trace. Waiting for a refund, cancellation, failed payment, or dispute turns a short filing job into detective work.

- Deposit report used to reconcile card volume

What BlueFinch would verify for med spas
BlueFinch would compare every proposed percentage and fixed charge against the same medical spa payment mix. Monthly, debit, PCI, gateway, batch, chargeback, software, and other account-specific costs may remain.
The current BlueFinch offer includes a standalone terminal at no charge, no equipment lease, no long-term contract, and no cancellation fee. Eligible configured credit-card transactions can carry a 0% merchant processing rate after the state, network, acquirer, written price display, and payment channels are reviewed.
Questions business owners ask
Should total business revenue be used in the effective-rate formula?
No. Use settled card volume from the merchant account. Include settled card sales and card deposits once. Exclude cash, checks, ACH, financing proceeds, insurance payments, gift-card redemptions, and balances that have not been collected.
What if an annual fee lands in one statement?
Show it separately or allocate it consistently across the comparison period. Do not erase it, and do not treat one unusual month as typical.
When should med spas stop this review and ask for help?
Stop when the statement, written price, customer document, terminal behavior, or receipt does not agree. The processor or acquirer should approve the exact setup before the medical spa launches it.
