You pay for every hour and bill only some of them. Assuming full utilisation produces a rate that cannot cover costs.
CHARGE FOR DIAGNOSIS, BECAUSE IT IS THE MOST VALUABLE SKILL AND THE ONE MOST OFTEN GIVEN AWAY
Offer it as a separate charge, deductible against the repair — and never read a fault code and simply replace the named component.
NEVER CARRY OUT ADDITIONAL WORK WITHOUT RECORDED APPROVAL
Unauthorised extra work is the commonest dispute in this trade. If the customer cannot be reached, stop and wait.
