Frequently Asked Questions

What is the difference between Free, Essentials, and Ultimate?

Free is a single-sheet starter template (sample data + How to Use guide). Essentials ($12) adds a dashboard, charts, expanded categories, and pre-filled subcategories. Ultimate (when available) adds multi-entity tracking, scenario analysis, and power-user reporting across 6-7 interconnected sheets.

Should I upgrade to Essentials?

Upgrade to Essentials if you want a dashboard with charts, more categories, larger capacity, and a more polished spreadsheet for ongoing use. The Free version is a good fit for one-off planning or trying out the layout.

Is Essentials worth $12?

Essentials is a one-time $12 purchase with no subscription. It typically adds a full dashboard, 30-50% more categories or rows than the Free version, and richer formulas. Most buyers upgrade after using the Free version for a few weeks and hitting its limits.

What is included in the free version?

The free Service Invoice is a single-sheet template with sample data and a "How to Use" guide. It covers the essentials. The Essentials version ($12) adds a dashboard, larger capacity, and extended categories; Ultimate (when available) adds multi-entity tracking and ultimate-grade reporting.

How do I add more line items?

Insert a row above the subtotal. Copy the formula from an existing line-item row so the amount column continues to calculate.

Can I customize the branding?

Yes. Replace the placeholder name and contact details in the header, and change the sheet colors through the normal Excel/Sheets formatting tools.

Is the file safe to download?

Yes. No macros, no sign-up, no tracking. The file is a plain .xlsx that opens directly in Excel, Google Sheets, or LibreOffice Calc.

How do I open this in Google Sheets?

Upload the .xlsx file to Google Drive, then open it with Google Sheets. All formulas and formatting will be preserved.
