Mobile Car Wash Booking and Invoicing App (2026)
For a solo mobile car wash operator, ShowTheReceipts ($15/mo) covers the whole job — let customers book a package tier online, invoice on completion, take the card before you drive off, and keep cash, card, and Venmo payments in one ledger for tax season.
How we picked
Entry-plan prices as published in 2026, checked against each vendor's own pricing page or a recent third-party pricing summary. We judged tools on the solo mobile operator's real workflow — package-tier booking, same-day invoicing, and on-site payment — not multi-van fleet dispatch.
| Software | Starting price | Best for |
|---|---|---|
| ShowTheReceipts That's us | $15/mo | Solo operators: package-tier quoting, same-day invoice, card payment, cash & Venmo tracked, tax-ready books |
| Kickserv Flex | $19/mo | Budget scheduling + invoicing, no vehicle-specific booking fields |
| Urable | $45/mo (Express, unlimited users) | The auto-care specialist: 24/7 self-service booking with deposit collection, unlimited users at every tier |
| QuoteIQ | $29.99/mo | AI estimating for package upsells and add-on services |
| Fieldd | Custom / quote-based | More advanced booking automation for a growing multi-van operation — pricing not published, and likely more than a solo operator needs |

================================================================================Mobile car wash pricing math: Package tiers vs. vehicle sizes
Pricing mobile car washes balances travel van overhead with volume efficiency:
- Express Exterior Wash ($45–$65 base): 30-minute eco-wash including hand wash, spot-free DI rinse, wheel cleaning, and tire shine. Require a 2-car minimum for residential visits to cover travel time.
- Wash & Interior Cleaning ($85–$145): Adds interior vacuuming, dashboard wipe-down, window cleaning, and door jamb wiping. Takes 60 to 90 minutes.
- Full Detail & Paint Protection ($195–$350+): Includes paint decontamination clay bar, machine polish wax, deep carpet shampoo extraction, and leather conditioning.
Itemizing pet hair removal, vehicle size surcharges, and deposits
Protect mobile wash margins with transparent line-item surcharges:
- Vehicle Size Surcharges ($20–$50): Washing a full-size suburban SUV requires 40% more water, chemical soap, and ladder reaching than a Honda Civic. Always itemize size multipliers.
- Heavy Pet Hair Extraction ($35–$65): Entangled dog hair requires specialized rubber pet hair brushes and extra vacuuming time. Itemizing pet hair prevents scope creep.
- 20% Online Booking Deposits: Mobile operators waste gas traveling to no-show appointments. Requiring a 20% deposit online locks in the appointment slot.
Driveway card payment collection
- Final Vehicle Walkaround: Perform a joint inspection with the car owner to demonstrate spot-free glass, clean wheels, and vacuumed carpets.
- Driveway Card Processing: Swipe the customer’s credit card or accept Apple Pay on your mobile phone before packing up your pressure washer and water tank.

Frequently asked questions
What software does a solo mobile car wash operator actually need?
A way for customers to book a package tier (basic wash, full detail, premium) online, same-day invoicing, and on-site card payment — not multi-van fleet dispatch built for a business with several trucks running routes.
What do I get with ShowTheReceipts for $15/month?
The solo-operator workflow at the lowest paid price — package-tier quoting, same-day invoicing, on-site card payment, and cash/Venmo tracked in the same ledger with tax-ready exports at year end.
Is Urable worth the higher price over a general invoicing app?
Urable's 24/7 self-service booking with deposit collection is a real differentiator if online booking volume is a meaningful part of your business — its unlimited-user pricing at every tier is also worth noting if you expect to add help soon.
