Excel Templates

The formulas are built and tested before a file goes up, the input cells are the only ones left unlocked, and every workbook has a short read-me tab telling you which three cells to change first. No macros, so nothing gets blocked by your IT department or mangled on the way into Google Sheets.

We keep the maths visible rather than hidden behind add-ins: if you want to know where a number came from, click it and read the formula. Where a template does something opinionated — a savings rule, a tax split, a day-rate calculation — the product page says so, and you can change it without the rest of the workbook falling over.
