Overview

What phone diagnostic-fee quoting is, and the hard line around it.

An AI agent for phone diagnostic-fee quoting is a 24/7 digital assistant that reads your published diagnostic or trip fee from a fixed price list, states it aloud with the conditions attached, records that the caller heard and accepted it, and books the visit. It stops callers from being surprised at the door by a fee nobody mentioned when the call was taken in a hurry. The boundaries are strict and worth stating up front. The agent quotes only what is written on your price list — the standard diagnostic fee, the after-hours rate, the zone trip charge, any waiver conditions. It does not estimate what the repair will cost, because that depends on what the technician finds. And it does not take payment: Agentplace agents cannot handle money, so the fee is collected by your technician or through your existing invoicing exactly as it is today.


Capabilities

What the Diagnostic Fee Quoting Agent does

Reads the published fee, states the conditions, records the acceptance.

01

Reads the diagnostic or trip fee straight from your fixed price list

02

Applies the right variant — standard hours, after hours, weekend, or zone surcharge

03

States any waiver condition, such as the fee being credited if work is approved

04

Declines to estimate the repair cost and says why in one plain sentence

05

Records that the fee was stated and accepted, with the timestamp and recording

06

Books the visit once the caller agrees, or ends the call politely if they do not

Why you should use the Diagnostic Fee Quoting Agent

The diagnostic fee is the most avoidable argument in home services. It is a fixed, published number, and almost every dispute about it comes from nobody saying it out loud when the appointment was booked. Having the agent state it on every call — same wording, same conditions, with the recording kept — removes both the awkwardness and the ambiguity. Callers who will not pay it say so on the phone, which is a much cheaper place to find out than a driveway.

Before
The fee is mentioned on some calls and forgotten on others
Technicians have the pricing argument at the door instead of the office
After-hours and zone surcharges are applied inconsistently
Someone guesses a repair price on the phone and the visit has to honor it
Price shoppers take a slot they were never going to keep
After
Every caller hears the published fee in the same words before booking
The correct variant is applied by time of day and zone, every time
Repair pricing is deferred to the technician with a clear, consistent reason
Acceptance is recorded with a timestamp and the call recording
Callers unwilling to pay the fee decline on the phone, not at the door
Process

How it works

A simple, three-step flow.

Step 01

Work out which fee applies

Job type, time of day and postcode zone decide which line of your price list is relevant. The agent looks it up rather than calculating anything itself.

Step 02

State the fee and its conditions

It reads the figure aloud with the wording you approved, including whether the fee is credited against approved work, and asks the caller to confirm they are happy.

Step 03

Book, record and hand over payment

On agreement the visit is booked and the acceptance is logged with the recording. Payment itself is left entirely to your technician or your existing invoicing process.


Example

Example workflow

A realistic use case with concrete timing and output.

Scenario: a home services company publishes an eighty-nine pound diagnostic fee during business hours, one hundred and forty after 6pm and at weekends, and credits the fee against any repair over three hundred. At 7:20pm a caller rings about a unit that has stopped working. The agent establishes the job type and postcode, looks up the after-hours line, and says: "Our call-out this evening is one hundred and forty pounds, and that is credited against the repair if you go ahead and the work is over three hundred. A morning visit would be eighty-nine. Which would you prefer?" The caller picks the morning, the visit is booked for 8am to 11am, and the acceptance is logged with the recording. Two other evening callers hear the same figure and one declines — a slot that stays open for someone who will keep it.

FAQ

FAQ

Common questions about using the AI agent in workflows.

An AI agent for phone diagnostic-fee quoting is a 24/7 digital assistant that reads your published diagnostic or trip fee from a fixed price list, states it aloud with the conditions attached, records that the caller accepted it, and books the visit. It stops callers being surprised at the door by a fee nobody mentioned on the phone. Unlike a person working from memory, it applies the same figure and the same wording on every call.

No, and this is a hard limit rather than a setting. Repair cost depends on the part and the labor the technician finds on site, so the agent has no source to read from. When a caller presses, it repeats one plain line — the technician will quote after diagnosing — and does not produce a number on the second or third ask.

No. Agentplace agents cannot take money of any kind, so there is no card capture, no deposit and no payment link. The fee is stated and agreed on the call, and collected by your technician or through your existing invoicing exactly as it is now.

By looking up the right line of your price list based on the slot being discussed, not the time the call came in. That means it can honestly tell a 7pm caller both figures — the evening rate and the morning rate — and let them choose, which is often the thing that converts the call.

It restates the published figure once, in the approved wording, and does not negotiate. Discounts, waivers outside your written policy and goodwill decisions are for a person, so the call is transferred or a callback is offered rather than the agent inventing an exception.

As a row with the timestamp, the caller's number, the figure that was stated and a link to the recording, plus a note on the booked job so the technician's app shows the same amount. Nothing is left to be remembered from a conversation.

Yes. Once the fee is accepted the agent checks live availability, offers two real windows, books the visit and confirms it aloud and by text. It hands over to a person if the caller wants to negotiate, if the address is out of area, or if the job type is not on your list.
