Warranty tracking spreadsheet: columns

Most warranty tracking templates have a job column, a date column, and little else. A workable sheet needs more: one row per completed job, with the manufacturer and program, the completion date, that program's registration window in days, the computed deadline, and a status that distinguishes due, submitted (with the date), and confirmed. The columns that matter are the ones that usually aren't there.

What columns does a warranty tracking spreadsheet need?

• Job and customer. What was installed, where, and when.
• Manufacturer and program. The certification program the job falls under, which determines everything downstream.
• Completion date. The day the clock started.
• Registration window, in days. That program's own window, on the row rather than in someone's memory. This column makes the deadline math auditable, and most templates omit it, because windows differ per program.
• Computed deadline. Completion date plus window, per row.
• Status. Due, submitted with date, or confirmed. The submitted date is your evidence of timeliness, and "confirmed" should mean the manufacturer said so, not that someone assumed so.

Where does the spreadsheet break?

Three places. The deadline math breaks first: with different windows per program, one formula copied down a mixed-program sheet applies the wrong window to somebody's job. The error is silent, and it shows up later as a deadline missed by exactly the difference between two programs' windows. Alerting breaks second, because a spreadsheet says nothing unless someone opens it, and the weeks when jobs complete fastest are precisely the weeks nobody does. The handoff breaks third. The sheet lives with one owner, the crew completes jobs in the field, and the gap between "job done" and "row added" is where clocks start unrecorded.

What replaces it?

The same structure with the failure points removed. WarrantyTrail, part of Composed Studio, keeps the row-per-job model. Log a completed job and its deadline computes automatically from that manufacturer's registration window, so the right window applies every time without copied formulas. A nightly scan raises alerts at configurable 30/15/7-day horizons, which means nothing depends on someone remembering to open a file. Status runs from due to submitted by you to confirmed by manufacturer, and it never auto-advances; only a real manufacturer confirmation marks a registration confirmed. Certifications and training sit in the same system with the same alerting. The submission itself stays yours. WarrantyTrail does not file registrations in manufacturer portals on your behalf; it makes sure the person who does is never working from a stale sheet.
