Build Your Car Wash a Website, Membership Plans and Booking with AI

Mythex lets a car wash or detailing business build its website, monthly wash club, detailing bookings and fleet invoicing by describing them in chat. Prices by package and vehicle size live in one table, plan members are looked up by number plate, and fleet washes are logged by plate as they happen.

What runs a car wash besides water and chemicals

Demand follows the weather. The first dry Saturday after a week of rain fills the forecourt, and a wet Tuesday leaves the bays empty. Monthly plans are what smooth that out, but in many washes the staff know members by face rather than by any record, so plans get shared between cars and lapsed members are never chased. Detailing is the opposite of the drive-through: long booked jobs that tie up a bay and a detailer for hours. Fleet contracts add weekday volume and month-end invoices that the fleet manager will check line by line. And chemicals quietly eat margin when nobody measures cost per wash.

What you can build for car washes

Wash packages and sizes on one clear page

Show each package side by side with what it covers inside and out, priced for hatchbacks, SUVs and vans from one price table. Add your monthly plan terms, opening hours and an open, closed or short-wait banner you can flip from your phone, so nobody drives over in a freeze to find the bay shut.

Build a website for my hand car wash with four packages (exterior, wash and vac, mini valet, full valet), priced for small car, large car/SUV and van from one price table. Add a monthly plan section and a status banner (open, short wait, closed for weather) I can change from an admin page.

An unlimited wash club tied to the plate

Each plan belongs to one registration, so a plate check at the entrance tells staff whether the car is covered and which package it gets. Tiers can have a wash limit or be unlimited, family plans can cover more than one car, and members can pause over winter or while a car is off the road. Recurring billing runs through a payment provider you connect.

Build a car wash membership system with three monthly tiers (4 washes, 8 washes, unlimited). Each membership is tied to a registration plate, family plans can add up to three cars, and members can pause with a resume date. Staff get a plate search showing plan status, package and washes used this month.

Detailing slots sized by package and vehicle

Put only the long jobs on the calendar: full valets, interior deep cleans, machine polish and ceramic coatings. Slot length depends on the package and the size of the vehicle, bays or detailers act as resources so two details never share one bay, and drop-off and collection times are captured. If rain cancels the day, bookings move rather than disappear.

Build a booking page for detailing at my car wash. Services: full valet, interior deep clean, machine polish, ceramic coating, each with a duration per vehicle size. I have two detailing bays. Capture registration, drop-off and collection time, and let me move a whole day's bookings when the weather is bad.

Fleet invoices that list every plate

Log each fleet wash against the account at the time, with plate, date and package. At month end the invoice lists every wash with its price and the fleet's purchase order number. When a fleet manager checks it against their own records, the plates and dates settle any question in a minute.

Build fleet invoicing for my car wash. Fleet accounts have vehicles, a price per package and size, and a PO number. Staff log washes by plate at the bay; at month end create one invoice per account listing each wash with plate, date, package and price.

Washes beside the weather, and plan churn

Chart washes per day against a rain or dry note you record, split revenue between walk-in washes, details, plans and fleet, and count members joined and cancelled each month. Plan revenue on its own line shows whether the business is getting steadier or just enjoying a dry spell.

Build a dashboard for my car wash: washes per day with a weather tag (dry, rain, snow), revenue split by walk-in, detailing, plans and fleet, and new versus cancelled plan members per month with a chart over the last year.

Chemical cost per wash

Track shampoo, snow foam, wax and tyre shine by drum, plus microfibre towels and pads that wear out or walk off. Dividing what you used by washes done each month gives a cost per wash, which shows whether a package is priced right and catches heavy-handed foam and dressing use.

Build a stock tracker for my car wash chemicals and towels. Record drums received and finished per product, and work out chemical cost per wash each month from usage and the number of washes.

What to put on day one

Start with the two things that change behaviour: a price table everyone can see and a plate lookup for plan members. Load your current members from whatever list you keep, even a notebook, with plate, tier and start date. Put the lookup on a tablet at the entrance. Once staff trust it, add detailing bookings, then fleet logging. The dashboard comes last, when there is a few weeks of data to look at.

A rota built around the forecast

A fixed weekly rota leaves you short on the first dry weekend and overstaffed in a wet week. Ask for a rota with a core team plus a call-in list of people happy to work at short notice, open shifts that staff claim from their phone browser, and opening and closing duties like equipment checks attached to each shift. Text or email alerts need a messaging provider you connect with your own account.

Questions

Can I charge different prices for cars, SUVs and vans?

Yes. Ask for one price table by package and vehicle size. The website, booking form and invoices all read from it, so a change in one place shows everywhere.

Can I sell monthly unlimited wash plans?

Yes. Mythex builds the plans, tiers and member records, and recurring card payments run through a payment provider you connect with your own account.

Can staff check members by number plate?

Yes. Ask for a plate search at the top of the staff view. It shows the plan, the package covered, washes used and any note from the last visit.

Can customers book a valet online?

Yes. Put full valets and details on a booking page with durations by vehicle size, and keep quick washes as walk-ins so the calendar does not fill with no-shows.

Is it free to try?

Yes. The Free plan needs no credit card and includes daily credits to build and publish. Pro is $25/month for a custom domain, code editing and export, plus Android and iPhone apps that open your published app.
