Customer equipment and warranty

Register what you service; warranty is worked out from the install date and applied at billing, with a claim raised against the vendor.

Service → Equipment.

One record per unit at a customer's site: make, model, serial, where it sits, when it went in, and its meter if it has one. Every service order against it becomes its history, with findings from last time shown to the next technician.

Warranty is months from the install date (or a separate warranty start), and whether it covers parts, labour or both. Expiry is stored so "what expires next month" is a filter, not a calculation.

Applied at billing. A part or labour line on a covered unit bills at $0 and says so on the invoice ("— covered, no charge"), so the customer sees the value rather than a blank. The cost is still real: the part still leaves the truck and lands in cost of goods. A warranty claim for that cost opens against the vendor on the unit, and Service → Warranty claims tracks it from open to submitted to paid.

Retiring a unit stops its maintenance schedules and keeps its history.
