How the math works

Each platform’s export columns as its own help page documents them, read on the dates shown.

  1. eBay: Transaction reportSeller Hub → Payments → Reports → Transaction report: choose the transaction type and the start and end dates, then Create report. eBay emails you when the CSV is ready.eBay’s help page names the report’s details (Order ID, Item ID, Gross transaction amount, Net amount, Final value fee, Other fees, Shipping label, Seller collected tax …) but doesn’t publish the exact header row, and you can add or remove columns. Check the column choices below. eBay Help: Reconciling your eBay sales transactions · read October 28, 2026
  2. Poshmark: My Sales ReportPoshmark → your profile → Order Activity (web) or Me → Seller Tools → Insights (app) → Sales Report: choose a date range and Email Report; the email links to a CSV.Poshmark’s help page describes six columns (Bundle Order, Offer Order, Order Price, Seller Shipping Discount, Net Earnings, Texas Seller Fee Tax) and the shared Order ID of bundles. It doesn’t name the date or title columns, and the file has no fee column: Poshmark’s fee is worked out as Order Price − Net Earnings − the other deductions listed.

  3. Mercari: Gross Sales ReportOn Mercari.com, open your Gross Sales Report and choose the date or date range. Mercari’s help page describes the report’s columns but not the menu path or the file format; save the report as a CSV file to open it here.Mercari’s help page lists every column of the Gross Sales Report with its meaning.

  4. Etsy: Monthly statement CSVOn Etsy.com: Shop Manager → Finances → Monthly statements → View all monthly statements → choose the year and month → Generate CSV. Etsy emails you when the file is ready: select Take me to download, then Download CSV.Etsy’s help page names the monthly statement’s Info column and its fee and tax amounts, and says to subtract the fees and taxes from the sales. The other column names aren’t published, so check the column choices below. Etsy’s deposit and orders CSVs aren’t read here: a deposit is already net of fees and taxes, and the orders total doesn’t subtract canceled orders.

Exact header names on eBay, Poshmark and Etsy: Not modeled — their help pages describe the contents but don’t publish the full header row, so check the column roles after opening a file (October 28, 2026).

Files other than CSV: Not modeled — open a spreadsheet and save it as CSV first.
