AI agent: For a four-door car it's your price, depending on the film line. Want to know the difference between them?

AI agent: It depends on the film. I book by bay time, and today I have your open slots.

Create my agentWhat needs to be ready before turning the agent on in the store?
The agent answers what is written, and nothing beyond that. Have these points defined before you connect WhatsApp.
- The rate table by vehicle size, hatchback, sedan, pickup, utility vehicle and van, matched with each film line
- The lines the shop works with and the difference between them in heat, privacy and warranty
- The installation time of each service and how many cars fit in the bay per day
- The residential and commercial glass rate table, kept separate from the car table
- The warranty: term, what it covers and the procedure when the film bubbles or peels
- What the shop says about the light transmission rule and what it prefers to handle in person
Whether the agent closes the booking from the vehicle size table or whether a non-standard car waits for you to look at it before booking.
The most common mistake: Using a single price for any car. Glass on a crew-cab pickup and on a two-door hatchback is different work, and a single price turns into a discount at installation time or a service turned away in the bay. Read how to fix this.
