We engineered around the failure modes.
The pivot was not to build nicer-looking templates. It was to build templates that could not fail in the ways the generic ones did. Data validation on every input. VBA macros in Excel and Apps Script in Google Sheets to handle automation. Sheet protection on every formula cell. Error handling built into the architecture from the start, not bolted on at the end.
Every template now moves through a five-stage production pipeline before it ships: problem definition, data architecture, automation layer, defensive engineering, and documentation. No stage advances until its deliverables meet specification. This is not how template sellers typically work. It is how software engineers work. We applied that standard to spreadsheets.
The result is a template that works under real conditions, with real data, operated by someone who has never seen it before.
