The short version
- Separate payment channels before calculating a blended cost.
- Use collected revenue and actual tender reports.
- Model realistic behavior changes.
- Keep settlement timing in the decision.
A $12,000 repair order might include a carrier payment, a card-paid deductible, a customer-pay upgrade, and a prior deposit. One blended percentage cannot describe that collection path.
Separate payer and payment method before estimating what the shop spends to collect repair revenue. For this review, use one recent body shop sale and the payment record that followed it.

Body Shops Payment-Mix Model
Compare credit, debit, and lower-cost payment channels in one month.
- Monthly collected revenue: example input 120000

- Debit-card share: example input 15
- Debit effective rate: example input 0.8
Open the live page to change the inputs. The calculation stays in the browser and uses only the values entered.
Price the channels separately before blending them
Body Shops should be able to trace every dollar in the model back to a tender report. If credit and debit account for less than 100%, the remainder belongs to cash, checks, ACH, financing, insurer payments, employer invoices, or another named channel.
Auto Body Shops rarely collect every dollar the same way. Credit, debit, cash, checks, ACH, financing, insurer payments, employer invoices, and account billing have different costs and settlement timing. One blended assumption hides which channel is creating the bill.
For body shops, the boundary matters. Do not count insurer checks, insurer ACH payments, financing proceeds, or other non-card receipts as card volume. Include only the money that actually runs through the merchant account.
Run body shop payment mix: insurer, ach, card, and cash through one real transaction
Model a body shop's payment mix across insurer payments, credit cards, debit cards, ACH, checks, cash, financing, deductibles, and customer-pay work.
Separate payer and payment method before estimating what the shop spends to collect repair revenue. Do the review with a completed body shop transaction instead of a clean sales demo. Keep the original amount, payment method, customer-facing terms, change history, receipt, settlement record, and any later adjustment on the desk.
- Body Shop Payment Mix: Insurer, ACH, Card, and Cash, estimate and authorization check: Put the payment choices on customer-facing estimates before work is authorized, not only on a sign beside the terminal. Name the screen, document, and staff owner used at this point.
- Body Shop Payment Mix: Insurer, ACH, Card, and Cash, deductible or deposit check: Record who paid, how they paid, what the money applies to, and whether the amount is refundable under the shop's written policy. Name the screen, document, and staff owner used at this point.
- Body Shop Payment Mix: Insurer, ACH, Card, and Cash, supplement check: When the approved repair changes, keep the customer balance, insurer amount, invoice, and payment request synchronized. Name the screen, document, and staff owner used at this point.
- Body Shop Payment Mix: Insurer, ACH, Card, and Cash, delivery and refund check: Match the final invoice, terminal, receipt, release record, and any later refund to the same transaction history. Name the screen, document, and staff owner used at this point.
Use the Body Shops Payment-Mix Model
Open the tool with the source reports beside you. Start with collected revenue, not booked work. Assign each collected dollar to one payment channel. The shares should total 100 percent. Apply the actual cost for each channel, including fixed fees when they are material.
- Collected revenue for one representative month
- Credit-card share and effective rate
- Debit-card share and cost
- Cash, check, or ACH share and cost
- Financing, insurer, employer, or account-billing share
Body Shops payment-mix review workflow
Run the review through one recent body shop 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 |
|---|---|---|
| Estimate and authorization | Put the payment choices on customer-facing estimates before work is authorized, not only on a sign beside the terminal. | Attach the payment-mix review record at this stage. |
| Deductible or deposit | Record who paid, how they paid, what the money applies to, and whether the amount is refundable under the shop's written policy. | Attach the payment-mix review record at this stage. |
| Supplement | When the approved repair changes, keep the customer balance, insurer amount, invoice, and payment request synchronized. | Attach the payment-mix review record at this stage. |
| Delivery and refund | Match the final invoice, terminal, receipt, release record, and any later refund to the same transaction history. | Attach the payment-mix review record at this stage. |
Records for the payment-mix review
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.
- Tender report by payment method
- Merchant and bank deposit totals
- Financing or insurer remittance totals
- Refunds by original tender
- Unpaid invoices kept outside collected revenue
What BlueFinch would verify for body shops
BlueFinch would compare every proposed percentage and fixed charge against the same body shop 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
Do uncollected invoices belong in the payment-mix model?
No. Model collected money by the method that delivered it. Keep open receivables outside the total until they are paid.
Should the model assume every credit customer changes methods?
No. Use a conservative alternative based on payment choices the business already accepts and can explain.
When should body shops 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 body shop launches it.
