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.
Wrap shops collect large deposits and final balances, often through different channels. A base rate quoted during the sale does not show the complete cost of those transactions.
A three-statement audit for finding the real rate behind a processor's advertised percentage. For this review, use one recent vehicle wrap shop sale and the payment record that followed it.

Wrap Shops Effective-Rate Worksheet
Enter one statement period. Nothing is saved or sent.
- Settled card volume: example input 52500
- Complete processing fees: example input 1859
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, wrap shops with $52,500 in settled card sales and $1,859 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 vehicle wrap shop 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 wrap shops, the boundary matters. Count card deposits and card-paid final balances once. Exclude checks, ACH, financing proceeds, and invoices that have not been collected.

What BlueFinch would verify for wrap shops
BlueFinch would compare every proposed percentage and fixed charge against the same vehicle wrap 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
Should total business revenue be used in the effective-rate formula?
No. Use settled card volume from the merchant account. Count card deposits and card-paid final balances once. Exclude checks, ACH, financing proceeds, and invoices 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 wrap 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 vehicle wrap shop launches it.
