The short version
- Show both prices before the customer pays an appointment deposit or final balance.
- Explain the prices consistently in bookings, at the shop and on mobile jobs.
- Link the film and vehicle records to the invoice, receipt and warranty records.
- Before launch, test debit, remote cards, wallets, refunds and bundled services.
One appointment might need a small booking deposit; another might end with a large payment for tint, paint protection film and coating. Payments may happen at the counter, on a mobile terminal or through a link. A single sign and terminal script won't cover them all.
Review dual pricing through the whole appointment. Show the regular card price and lower cash price before payment, identify the vehicle and work, and keep the invoice, receipt, installation record and warranty paperwork consistent.

Check your own costs: calculate your effective processing rate or upload a merchant statement for analysis.
Use every processing cost to find the effective rate
For a complete statement period, add percentage charges, per-transaction charges, monthly account costs, gateway charges, PCI fees, batch fees and any other processing costs belonging to that period. Divide the total by settled card volume.
A $1,400 complete bill on $40,000 in settled card sales gives a 3.5% effective rate. This illustrates the arithmetic; it isn't a tint-shop benchmark. Use recent statements and reconcile deposits to avoid counting the same sale twice.
Show the choice when you collect the booking deposit
For online or text deposit requests, show the applicable prices and deposit terms before submission. Explain what the deposit reserves, how you'll apply it and the written cancellation or no-show policy.
Don't leave the website or booking tool showing one amount while the counter shows two. Before enabling a payment feature, confirm that the processor-approved program supports its channel.
Match each payment to the vehicle and film records
3M's warranty information identifies the customer, product, vehicle, installer, date and original invoice. For other manufacturers, follow their current process. Keep payment records connected to the same job as the installation and warranty records; one doesn't replace the others.
| Stage | Customer-facing detail | Record |
|---|---|---|
| Booking | Explain the service, deposit, both prices and cancellation terms | Appointment record and payment receipt |
| Check-in | Confirm the vehicle, glass, film, shade, package and current total | Work order with customer acknowledgment |
| Change | Identify added removal, PPF, coating or other scope changes | Updated authorization and price |
| Delivery | Show the final balance and payment choice | Invoice, receipt, care instructions and warranty information |
Check tint legality separately from payment pricing
Tint laws differ by jurisdiction. Approval for dual pricing doesn't approve a film, shade, windshield area, exemption or vehicle application. Choose the product using current state-specific legal sources and your shop's compliance process.
A fifty-state tint-law chart in a payment article can quickly go out of date. Use current local guidance to document the chosen film and any required acknowledgment.
Compare the full proposal and how it changes your work
BlueFinch can currently provide a 0% merchant card rate on eligible, configured credit and debit transactions, a standalone terminal at no charge, signs and launch support. There is no equipment lease, long-term contract or cancellation fee. Account-specific monthly, PCI, gateway, batch, chargeback and other fees may still apply.
Check state law, the processor agreement, network rules, card treatment, price display, mobile use, booking links, refunds and equipment ownership. Compare a representative year with your shop's actual mix of payments.
Questions business owners ask
Can we offer dual pricing for a booking deposit?
Only if the approved booking or remote process shows the required choice and terms before payment. Confirm that channel with the processor or acquirer.
Is a digital-wallet payment always credit?
No. A wallet can hold credit or debit, but both pay the posted card price under dual pricing. Test the wallet with the approved terminal before launch instead of guessing.
Does BlueFinch decide which tint we can install?
No. Tint legality is a separate, state-specific matter. Use current official sources and appropriate professional guidance.
Does the free terminal replace our scheduler?
The standard terminal works beside your existing scheduler or POS. Direct connections, deposit transfers and automatic receipts depend on the platform and configuration.
