Session 8: Service Workflow & Final Practical

Almost every dispute in repair work traces back to an undocumented intake. The customer says 'it was working yesterday', you open it and find a cracked board, and now there is an argument about who broke it — because nobody recorded the machine's condition on arrival. Intake takes five minutes and it prevents all of it.

Record four things. The machine: make, exact model, serial, and a photograph of its condition on arrival, including any existing cracks, dents or missing screws. The reported fault in the customer's own words, not your interpretation of them. What is on it: whether there is data that matters, whether it is backed up, and written acknowledgement that you are not responsible for data loss if the drive fails during work. And the terms: your diagnostic fee, whether it is credited against the repair, and that you will quote before doing any work beyond diagnosis.

That last point is the one that protects your time. A machine that arrives with no agreement on a diagnostic fee becomes a machine you have worked on for free and cannot charge for. Stating a fee up front, in writing, is not distrust — it is what makes the relationship professional, and customers accept it readily when it is presented calmly as standard practice.

Diagnosis can consume unlimited time if you let it, and unpaid diagnosis is how repair businesses quietly fail. Set a time box — thirty to sixty minutes for a standard fault — and work the systematic method from the earlier sessions: simplest external cause first, then evidence rather than part swapping, then the specific tests for the fault family you have identified.

When the time box expires, make a decision rather than continuing: either you have a diagnosis and can quote, or you do not and you tell the customer what you found, what remains uncertain, and what further diagnosis would cost. Both outcomes are professional. Drifting into a fourth hour on a difficult fault, unpaid and without telling anyone, is neither.

The diagnostic fee exists precisely to cover this. Charge it, credit it against the repair if the customer proceeds, and it stops being lost time. Customers who decline a repair after diagnosis still owe for the diagnosis, and saying so at intake makes that conversation easy instead of awkward. This single practice is the difference between a repair business that pays its owner and one that does not.

You are inside someone's personal machine, with access to their photographs, their messages and possibly their banking. The professional standard is firm: do not browse. Open only what the job requires, do not read what you do not need to, and never copy anything. Where you must access files to recover data, do it in front of the customer where possible, or with their explicit permission, and tell them what you opened and why.

Passwords are the awkward part. Sometimes you need to log in to diagnose. Ask the customer to enter the password themselves rather than telling it to you wherever that is possible, and if you must have it, do not write it down anywhere persistent and change nothing. If you reset a password to gain access, tell the customer clearly that you did and that they should change it.

Expectations are where most dissatisfaction originates, and they are set by what you say at intake. Do not promise a same-day fix you cannot guarantee. Do not quote a price before diagnosing, because a guessed price becomes a promise. Do say: 'I will diagnose it and call you with what I found and what it will cost, and I will not do any work beyond diagnosis without your agreement.' That sentence protects you from every version of this argument.

Keep a job record for every machine: the intake details, what you found, what you did, what parts you fitted with their cost, what you charged, and the date. It takes two minutes per job and it is what lets you answer 'what did you do to my laptop six months ago?' instantly. It is also what turns a repeat customer into a relationship, because you remember their machine.

Three documents matter. An intake form capturing machine, condition photographs, reported fault, data acknowledgement and terms. A quote stating the diagnosis, the parts, the labour and the total, with an expiry, so the customer agrees before work begins. And a receipt or invoice stating what was done and any warranty you offer — commonly thirty to ninety days on labour and the manufacturer's period on parts, which is standard practice and worth stating explicitly rather than leaving ambiguous.

Be clear about the warranty's limits in writing: it covers the work you did, not unrelated failures, and not damage caused afterwards. That clarity is not defensive; it prevents a customer bringing back a machine dropped two months later and expecting a free repair, and it is far kinder to say it at the start than to argue about it later.

Price repair work on parts plus labour at an honest hourly rate, and be able to explain both. Customers accept a fair price far more readily than they accept an unexplained one, and showing the arithmetic — 'the drive is ₦X, the work is about an hour at ₦Y' — turns a negotiation into a conversation. Underselling is the common beginner error: it attracts the most difficult customers, it makes the work unsustainable, and it makes raising prices later feel like a betrayal.

Then understand what actually builds this business: honesty about whether a repair is worth doing. The technician who says 'this is not worth repairing, here is why, and here is what I would buy instead' is remembered and referred, permanently. The technician who repairs a dead machine for a large fee is paid once and talked about badly forever. In a market where everyone knows everyone, that difference is the entire business.

The compounding assets are a reputation for honesty, a record of your work that lets you serve repeat customers well, and referrals, which in Nigeria come overwhelmingly from personal recommendation rather than advertising. Do the honest thing on every job, document it, and the work arrives. That is not a platitude; it is the actual operating model of every successful repair business in this market.
