Overview

Reseller Navigator runs your whole reselling business from one workbook. Log each item once, move it through the 7-stage pipeline — purchased, cleaned, photographed, listed, sold, shipped, delivered — and watch fees, profit, ROI, and margin calculate themselves on every sale.

Built for the platforms resellers actually use: eBay, Etsy, Mercari, Poshmark, Whatnot, Facebook Marketplace, Shopify, and local sales. The Fees & Taxes tab estimates platform fees and sets aside what you'll owe; Mileage applies the IRS standard rate; Reports produce a print-ready P&L for tax time.

The Analytics tab shows inventory aging and your best (and worst) performers, so sourcing gets smarter every month.

Benefits

What changes for you

Every item, every stage, at a glance

The pipeline shows exactly where every item stands right now — no more mystery bins or forgotten listings.

Real profit, not gross revenue

Fees, shipping, cost basis, and mileage are all in the math, so the profit number you see is the one that's true.

Tax season becomes a print job

The Reports tab produces the P&L and expense summaries your tax preparer actually wants.

Who it's for

eBay, Etsy, Mercari, Poshmark, and Whatnot sellers
Thrift flippers and estate sale hunters
Anyone selling on multiple platforms at once
Resellers who want real numbers at tax time

Who it's not for

Questions

Frequently asked questions

It ships with defaults for major platforms (eBay, Etsy, Mercari, Poshmark, and more) that you can adjust in Business Setup as fee structures change.

No. Everything is pre-built — formulas, charts, and dashboards are ready to go. You only type into clearly marked input cells (they’re highlighted), and a Welcome tab walks you through setup in about ten minutes.

Yes. The workbook is a standard Excel file (.xlsx) that works on Mac, Windows, and Excel for the web. Microsoft 365 is recommended for the best experience.

The workbooks are designed and tested for Microsoft Excel. Google Sheets can import .xlsx files, but some advanced formulas and charts may not convert perfectly, so we don’t officially support Sheets at this time.

Completely. This is a file you own, on your computer. There’s no account, no cloud sync, and no data collection — your numbers never leave the workbook.
