ResellerLedger — Sales & Profit Tracker

About

Sell on more than one platform? See all your profit in one place.

eBay only knows your eBay sales. Mercari only knows Mercari. ResellerLedger pulls your own sold orders from eBay, Mercari, Poshmark, and Depop into a single ledger, lets you add what each item cost you, and instantly shows your real net profit and margin — then exports it all to one clean, tax-ready CSV.

No more stitching four different reports together in a spreadsheet by hand.

How it works
1. Open your Sold / Orders page on any supported platform
2. Click "Scan this page" — those sales merge into your combined ledger
3. Repeat for each platform you sell on
4. Add your cost per item, then export one CSV with everything

What you get
• One combined view of sales across eBay, Mercari, Poshmark & Depop
• True net profit & margin per item (after fees, shipping, and your cost)
• Tax-ready totals: revenue, fees, COGS, and profit in one file
• CSV that opens straight in Excel or Google Sheets

Private by design
• 100% on-device — your sales data never leaves your browser
• No account, no sign-up, no cloud, no upload
• Reads only your own logged-in pages; never relists, shares, or automates anything

Free vs Pro
• Free: scan, view, and export up to 20 rows
• Pro ($19 one-time): unlimited rows and full history, all platforms — no subscription
