A few things to know

Do I need spreadsheet experience?

The tools include built-in structure and a companion guide. The calculator’s formulas are already set up, so you enter your numbers in the designated input cells.

Does the calculator connect to Shopify?

You enter your prices and costs manually in Google Sheets. No Shopify connection is required.

What does “profit” mean in the calculator?

Contribution profit is what remains from a sale after the per-unit costs you enter. Fixed overhead and taxes are excluded, so this is not your final net profit.

Does the supplier workbook choose a supplier for me?

You make the final decision. The workbook organizes the quotes, samples, and terms so you can compare the full offer.
