Reseller Profit & Inventory Tracker

Contents, not a copy. This is a spreadsheet, so there is nothing to run in a browser. Everything below was read straight out of the shipped file, so it is exactly what you would open — the sheet names, the columns and the fee table are the real ones. The formulas themselves are what you are paying for and are not reproduced here.

Four sheets

Start Here — how to use it, in the workbook rather than a separate PDF.
Fee Rates — eight marketplaces, editable, so you can match your own payout statements.
Inventory — 300 item rows, 25 columns, pre-filled with formulas to the last row.
Dashboard — totals and a per-marketplace breakdown, all calculated.

Inventory columns

You type these 16:

SKU · Item Name · Category · Source · Purchase Date · Item Cost · Shipping In · Supplies · Marketplace · List Date · List Price · Status · Sold Date · Sold Price · Ship Paid by Buyer · Actual Ship Cost

These 9 calculate themselves:

Gross Received · Marketplace Fee · Processing Fee · Net Received · Total Cost · Net Profit · Margin % · ROI % · Days to Sell

Rates researched 2026-09-29 and editable in the sheet. The same numbers drive the free fee comparison page, which is where to check them before buying anything.
