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.
Comparing a quoted percentage with total repair revenue can hide your actual rate. Insurer checks and ACH payments that bypass the merchant account don't belong in its card-volume total.
Work out how the advertised rate compares with the full card-processing bill. Work through a recent body shop sale with its payment records.

Calculate the full rate from your statement
With the worksheet's example values, body shops would have $54,000 in settled card sales and $1,912 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 body shop, 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 body shops, use the right payment totals. Only include money processed through the merchant account. Insurer checks, insurer ACH, financing proceeds and other non-card receipts are not card volume.

What BlueFinch would check for body shops
BlueFinch would use the same body shop 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. Only include money processed through the merchant account. Insurer checks, insurer ACH, financing proceeds and other non-card receipts are not card volume.
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 body shops need help with the review?
Pause if the statement, written price, customer documents, terminal or receipt disagree. Before the body shop launches, its processor or acquirer should approve the specific setup.
