Built lineside, not in a template farm

These tools are built and maintained by a working automotive manufacturing engineering manager with operations experience — the same spreadsheets, methods, and AIAG paperwork used to launch and run real production lines. Every formula is verified against an independent reference implementation before a tool ships. If a tool doesn't hold up on your floor, reply to your receipt and say so.

Will these work in my Excel?
Excel 2010 or newer, Microsoft 365, and LibreOffice. No macros, no add-ins, so IT has nothing to object to.
Can my whole team use one purchase?
A single purchase covers one user. Team and site licenses are coming — reply to your receipt and we'll sort you out early.
What if I break a formula?
You won't — formulas are locked (no password; you can unprotect anytime). And your receipt link always re-downloads a clean copy.
Updates?
Free forever on every tool you've bought. The version number is on each Read Me tab.
