Most templates fail the same two ways. They are so elaborate you need a tutorial before you can start, or one stray keystroke wipes a formula and you don't notice for three months.
Everything here is built against both problems. Every formula cell is locked, so the only cells you can type in are the ones you're supposed to. You enter your numbers in one tab, and the totals, summaries and dashboards fill themselves in. Every file opens in Microsoft Excel and in free Google Sheets, so you don't need a subscription to use what you bought.
Every download includes a one-page quickstart PDF that walks you from the download link to your first entry, because "where did my file go" should never be the hard part.
If something doesn't work, message me and I'll fix it. A broken spreadsheet is my problem, not yours.
