How car washes get paid
Car Washes take cards for most tickets, route larger repairs and fleet accounts over ACH, and reconcile it all through Flux.
A typical Flux setup for car washes
A wash has two customer types. Single washes are small payments at the pay lane, and those stay on the pay station you already run. Unlimited memberships are the business model, and that is where Flux fits: card-on-file subscriptions through the API, priced at the flat 2.9% plus 30 cents and settling in 1 to 2 business days. Members sign up through hosted fields, online from home or on their own phone at the lane, and are billed monthly on the anniversary date, with the revenue flowing into QuickBooks through the sync.
Weather runs the wash: a string of gray days empties the lanes while membership billing keeps running, which is the point of the model. Fleet washing for dealerships and delivery companies is invoiced monthly by ACH, settling in 1 to 3 business days. A large membership base billed every month is the textbook case for the custom interchange-plus pricing Flux offers at higher volume, worth a conversation once the member count grows.
What car washes should watch
Membership businesses live and die on cancellation hygiene. The classic wash dispute is a member who says they cancelled months ago and charges kept coming, and card networks side with cardholders when cancellation was hard to do. Make cancelling as easy as joining, confirm it in writing, stop billing immediately, and keep the recurring charge descriptor recognizable so a member scanning a statement sees the wash, not a mystery merchant worth disputing.
Renewal declines are the silent leak: cards expire, get reissued after fraud, or simply bounce, and every failed renewal is a member quietly lapsing. Pull decline data through the API weekly and reach out while the member still wants the plan. The other operational habit is fast refunds on damage claims, a snapped antenna refunded same day is a complaint; the same claim ignored for two weeks is a chargeback plus a bad review.
Simple, transparent pricing
Flux charges a flat 2.9% plus 30 cents per transaction, with volume discounts for higher-volume car washes and the option to run a cash discount program so customers who pay by card cover the processing fee. No setup fees and no contracts. Accounts processing under $100,000 a year in card volume may be subject to a $20 monthly account fee.
Frequently asked questions
How do car washes accept payments with Flux?
Car Washes accept credit and debit cards, ACH bank transfers, and stablecoins through one Flux integration, with drop-in hosted fields that keep card data off your own systems.
What does Flux charge car washes?
A flat 2.9% plus 30 cents per transaction, with volume discounts for higher-volume merchants and no setup fees or contracts. Accounts processing under $100,000 a year in card volume may be subject to a $20 monthly account fee. You can also run a cash discount program, so customers who pay by card cover the processing fee.
How fast do car washes get their money?
Card payments settle in one to two business days and ACH in one to three business days. Stablecoin payments go to your wallet instantly.
What happens when a member's card declines at renewal?
The subscription charge fails and the membership lapses unless you act. Pull decline data through the API, contact the member while they still want the plan, and update the card through hosted fields. Treat declines as a retention task, not an accounting one.
Can we sign up members at the lane and online with one system?
Yes. A member at the lane signs up on their own phone and a member at home signs up online, and both paths store the card through hosted fields into the same subscription through the API. The sync pushes membership payments into QuickBooks already categorized, and one membership record follows the customer regardless of where they joined.
How do we avoid disputes when a member cancels?
Stop billing the moment they ask, confirm it in writing, and keep the confirmation. Most membership chargebacks are cancellation arguments, a member who says they cancelled and got charged again, and a same-day written confirmation ends that argument before a bank ever hears it.
