Why this is different

This is not a printable planner. It is a working spreadsheet system: enter your real sales and stock data and the workbook calculates the key outputs for you.

Compatibility

Designed for modern Microsoft Excel on Mac and Windows. The file can also be opened in Google Sheets, but visual formatting and charts may not render identically.

Important

This workbook is a record-keeping and management tool. It is not accounting, tax, legal, investment or financial advice. Always verify figures before using them for filings or business decisions.

FAQ

Is this accounting software?

No. It is an operational record-keeping and management workbook.

Does it connect automatically to Etsy or eBay?

No. R1 is intentionally local and manual-entry. This keeps it simple, private, portable and free of recurring API dependencies.

Can I use it for more than one marketplace?

Yes. Orders can be tagged by platform and the dashboard summarizes profit by channel.

Do I need Excel?

Excel is recommended for the intended layout and charts. Google Sheets can open the workbook, but some formatting may differ.

Is there a subscription?

No. The R1 workbook is a one-time digital purchase.
