Every file starts with a "Start here" tab. Not a README, not a PDF — an actual first sheet that shows the 3 yellow cells to fill and what the dashboard will do with them.
The boring technical detail that makes it work: I never protect or lock sheets. Buyers treat locked cells as broken cells. Instead I highlight inputs in yellow and add inline formula hints (a tiny black corner comment on each input cell).
Workflow: Python (openpyxl) builds every workbook with real formulas — SUMIFS, VLOOKUP, PMT — then a headless recalculation pass verifies zero broken formulas before the file ships.
What's the one thing you add to every deliverable so it works without you in the room?
