Things people ask

Will an Excel workbook really do everything Notion + FreshBooks does?

No — that's honest. Notion + FreshBooks has features a spreadsheet can't match (live bank sync, mobile app, AI assistance). What the workbook does is the core math you actually use weekly. If you're paying $45/mo mostly for features you never open, switching saves you $540/yr. If you genuinely use the platform-specific features, stay where you are.

What's the catch with paying $19 once vs $45/mo?

No catch. The workbook is a .xlsx file you download and own. There's no expiry, no account, no cloud lock-in. You enter your own data manually — that's the friction trade. Over 10 years you'd pay Notion + FreshBooks roughly $5,400. The workbook costs $19 once, so you keep ~$5,381.0.

What spreadsheet apps does it open in?

Microsoft Excel, Google Sheets, and Apple Numbers — all three open .xlsx natively. Google Sheets and Apple Numbers are free. You don't need an Excel subscription.

How do I switch from Notion + FreshBooks?

Three steps: (1) export your historical data from Notion + FreshBooks as CSV, (2) open the gridmoo workbook and paste the data into the input sheets, (3) cancel your Notion + FreshBooks subscription. Most users finish the switch in 30–60 minutes.

No subscription. No login. No platform.

Microsoft Excel, Google Sheets, and Apple Numbers all open .xlsx files for free. Sheets and Numbers are free outright.

What this isn't: a phone app, a quick-tap logger, or a real-time collaboration tool. These are desk-and-keyboard files for weekly reviews and monthly numbers.
