The short version
- Winning the sale doesn't remove its processing cost.
- Calculate with contribution per completed sale, not total ticket value.
- Try both low and high margins.
- Read the result as arithmetic, not a prediction.
Collision repairs take physical work, skill and substantial costs. Card fees apply to the full payment, even though only part of the repair total is profit.
Compare card fees with what remains after parts, materials, labor, sublet work and overhead. Work through a recent body shop sale with its payment records.

Body shop paint material recovery: match billing to consumed cost
A supplier invoice shows stock purchased. The repair order needs materials consumed on that job. Match those costs before calculating recovery.
How many lost repairs would erase a body shop's payment-program savings?
Check remaining costs and any genuinely lost contribution before judging a lower processing bill.
Browse the complete auto body guides and worksheets.
Check your own costs: calculate your effective processing rate or upload a merchant statement for analysis.
Work out how many sales would cover the card bill
The example compares a monthly card bill of $1,912 with the contribution from one completed sale. Update the revenue, card share, rate, average ticket and contribution together. An overly optimistic margin can make the calculated number of replacement sales meaningless.
A processing percentage can seem small until you compare it with jobs, labor hours, appointments or gross profit. This worksheet compares the monthly card bill with what one completed sale contributes, showing the cost in terms of work.
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.

- Percentage of collected sales paid by card
- All-in effective processing rate
- Average value of a completed sale

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.
- Three complete merchant statements
- Sales reports for those months
- Completed-job or appointment count
- Totals for refunds and cancellations
- Margin assumption with its source
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
Why enter the contribution from a completed sale?
The owner doesn't keep the whole ticket amount. Using contribution gives a better estimate of the completed work needed to earn back the processing expense.
Is the example margin typical for body shops?
No. The defaults are labeled examples. Use your own reports to document both a low and a high case.
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.
