Ask for model numbers, photos, dimensions, or previous service records. Check stock or supplier availability before promising completion. For uncertain diagnoses, explain that a first visit may identify the correct part and a second visit may be needed.
Before dispatch, confirm the make or model, dimensions, fault symptoms, site access, and any part number that can be checked safely. Review job history and stock records, but do not assume a customer's description identifies the failed component. If an unknown part may be needed, explain the chance of a second visit and how approval for a purchase will work. Update stock after each job.
Set a customer-approved spending limit for parts, or request approval for every purchase above the estimate.
Check common consumables and parts before leaving and record what was used after each job. For an uncertain fault, explain that diagnosis may reveal a different component and agree the approval threshold. Do not carry customer-specific parts between jobs without labelling and keeping them secure.
Track parts-related callbacks to improve preparation. State how diagnosis and follow-up work on a KobStore service page; create one.
