Charge for Diagnosis, Not Just the Successful Repair

Click Listen to the Audio Version

EPISODE 06  Diagnosis is valuable work. Treating it as free teaches customers to value it at exactly that price.

Diagnosis is skilled work. It uses time, tools, experience and judgement, even when the customer decides not to continue. Treating it as free teaches customers that your most valuable thinking has no value.

Why this matters

Small detail. Big knock on effect. A diagnostic charge creates a fair starting point for uncertain work. It also lets you slow down, record symptoms, test properly and produce a useful recommendation rather than guessing a price at the counter or on the phone.

Follow the money

This is where effort starts paying. Free diagnosis transfers the cost of uncertainty from the customer to the repairer. It can attract devices with little economic value, encourage speculative enquiries and pressure technicians to rush towards a sale. A paid diagnostic service changes the conversation. The customer buys reliable information and the business can investigate carefully even when the final recommendation is not to repair.

Shop, callout or MSP?

Repair shop: A shop can use a fixed assessment fee for common device types, with the fee handled consistently if the repair proceeds.

Callout technician: A callout technician can charge for the visit and initial assessment, then quote separately when parts, extra time or workshop work are required.

MSP: An MSP can separate discovery, audit and project planning from routine support. Complex proposals shouldn't consume unlimited unpaid engineering time.

From my own experience

From my repair bench: the mystery white dust

In the mid to late 2000s, Computers became popular in bedrooms, I started opening computers from the bedrooms and finding a strange fine white dust inside. It was tempting to jump straight to a dramatic answer. The real source was often deodorant spray. The fans had been pulling the mist through the case and coating the components.

On another job, the white dust had a completely different source. A cat litter tray was sitting beside the computer. The PC had been breathing in the litter dust every time its fans ran. Same colour. Similar build-up. Very different customer conversation.

That is why diagnosis is paid work. A technician has to observe, test and ask the question nobody thought mattered. Guessing from the first clue is quick, but it is not professional. The answer is not always hiding in a diagnostic code. Sometimes it is sitting next to the tower with a small plastic scoop.

Diagnosis starts before the screwdriver

Diagnosis is not a warm up for the paid work. It is the skilled work that decides whether anything else should happen.

Diagnosis uses equipment, software, training, experience and time. It carries risk. It may require disassembly, research, substitute parts, updates, repeated testing and the patience to wait for an intermittent fault to stop pretending it is fixed.

A diagnostic fee should be clear before intake. State what it covers, whether it is credited towards an approved repair and what the customer receives if they decline. The result may be a repair quote, a report, confirmation that data recovery is needed or advice that replacement is better value.

If the business costs £100,000 a year and has 2,000 genuinely billable hours, the cost is £50 per productive hour before profit. Charging £45 does not make you competitive. It makes each successful hour five pounds worse.

Do not promise a final repair price before diagnosis where the device may hide more damage. A liquid-damaged laptop is not one fault. It is a crime scene with a keyboard.

Measure it or guess forever

Track diagnostic fees collected, conversion into repair work and time spent on declined jobs. The service should cover the cost of professional investigation without relying on every quote being accepted.

Reality check: Don't describe the fee as a penalty for refusing a repair. Present it as a professional service that gives the customer reliable information and a choice.

Do this now: Write your diagnostic description and the sentence staff will use when explaining it.

No hiding. Answer these.

•      What exactly does diagnosis include?

•      When is the fee credited against repair?

•      What evidence does the customer receive?

•      How are no fault found cases handled?

The bottom line

Bluntly: Fault-finding is work; the screwdriver is not the only employee in the room.
