Auto detailing: booking calls without stopping the buffer

Nobody on the phone can see the car

We'll start with the limit. Whoever answers your phone, a person or an AI, is pricing a car they can't see, described by an owner who thinks "a bit of dog hair" covers it. So auto detailing booking by phone is never really a final price and a locked slot. It's a fair estimate, a requested date, and enough detail that you aren't surprised when you pull up.

That's the job an AI line does well. It answers while you're mid-pass with the polisher, quotes your packages by vehicle size, checks the address against your service area, takes the date the customer wants, and sends you a written note. You confirm the booking in whatever you schedule with. CosVoice doesn't link into booking apps, and the line doesn't take deposits.

How does it quote by vehicle size?

Your price sheet is a grid. Packages down the side: maintenance wash, interior only, full detail, paint correction, ceramic coating. Sizes across the top: coupe or sedan, small SUV, large SUV or truck, van or anything with a third row. You give the line the grid, plus a rule for which vehicles fall in which column.

The caller says what they drive, the line finds the column and quotes the package from your sheet. It quotes nothing that isn't on the sheet. For work you'd never price blind (correction and coatings, mostly) it takes the details and says you'll call with a quote after seeing the paint.

What should it ask about condition?

This is where a detailer's estimate lives or dies. Have the line ask what you'd ask: when it was last detailed, pets, kids, smoking, spills, sand, anything on the paint like sap or overspray. It writes the answers in the caller's words.

Then it quotes your add-ons as "from" prices and says the final figure is set when you've seen the vehicle. Customers take that well when they hear it on the first call. They take it badly when they hear it for the first time in their own driveway.

Will it know where you travel?

It knows what you tell it. Give it your service area as towns or zip codes, the travel fee beyond that line, and the places you don't go. It asks for the address early in the call, so nobody spends five minutes choosing a package you can't deliver.

For mobile work it also asks what you need to know before you load the van. House or apartment? Driveway, garage or street? Is there water and an outlet on site, if you rely on the customer's? Any rules at the building about washing cars? Every one of those is a wasted trip if nobody asks.

What happens when it rains?

Two kinds of call. The customer rings to move their booking because the forecast has turned. The line takes it, offers the next windows you've allowed, and sends you the request to confirm. It states your policy as you wrote it, including how much notice you ask for.

The other kind is you moving them. Tomorrow's a washout and you've got five driveways booked. That's an evening on the phone, or it's one instruction. Ask the line to call each customer, explain, and offer the two alternative days you've given it. It reports back with who took which day and who didn't pick up. Texts from the line to customers are limited for now, so these go as calls or emails.

Fleet inquiries are a different call

A landscaping firm with nine trucks. A used car lot. A shuttle operator. These callers aren't asking for a Saturday slot, and a line that answers them with your retail grid loses the account.

So the line switches to questions. How many vehicles, and what kind? How often? Where are they parked, and can the work be done on site after hours? Who decides, and how do they want to be invoiced? It doesn't quote a fleet rate unless you've given it one. It takes the details, gives the line's own email address for a vehicle list typed into the message, and promises a call from you. (That address keeps the text of an email and not attachments. If fleet managers will want to send a spreadsheet, put your own inbox in the instructions.) There's more on the automotive page.

A starting brief you can copy

Write the instructions the way you'd brief a new hire on their first morning. Short sentences, real numbers. Something like the example below, with your own details in place of the brackets. Our guide to writing a call brief that works goes further, and plans are on the pricing page.

"You are the assistant for [business], a mobile detailing service covering [towns]. Quote only from this price sheet: [packages by vehicle size]. Add-ons are 'from' prices, and the final price is set on inspection. Never quote paint correction or coatings. Take the details and say the owner will call."

"Always get: name, phone, vehicle, condition, address, parking, water and power on site, preferred dates. Bookings are requests until the owner confirms. Rain policy: [policy]. Fleet callers: ask how many vehicles, what type, how often and where, then promise a callback. Never take card numbers."
