Know what every sale actually earned you.

The Google Sheets version works in any modern browser with a free Google account — nothing to install. The Excel version is a standard .xlsx workbook, fully tested in Microsoft 365 and Excel 2019 or newer. Older Excel versions and third-party spreadsheet apps (LibreOffice, Apple Numbers) will open it, but some dashboard formatting and data-validation dropdowns may not carry over — if that's your setup, use the Sheets version; it's the same system.

You don't maintain anything. Each edition's fee tables are checked against the platforms' published fee schedules before release — this edition (2026.1) was checked in November 2026, and the Fee Reference tab shows the date. We re-check quarterly and release a new annual edition every January. When an updated edition releases, past buyers can buy it at a discount with the code in the next answer. If a platform changes a fee mid-quarter in a way that materially changes the maths, we'll note it in this FAQ.

Corrections to your edition are free — if we fix a file, we update it on the listing and you can re-download it free from your Purchases page any time. New editions (quarterly refreshes when fees change, and the annual January edition) are new listings; past buyers of the product get 40% off the list price of the new edition with the code PASTBUYER40. The discount exists because your data setup carries over — a new edition is a fee-table refresh, not a repurchase of the whole idea.

Digital items don't accept returns, exchanges, or cancellations on Etsy — the file can't be un-downloaded. But if the file won't open, the link fails, or a formula is wrong, message us through Etsy or Gumroad with your order number: we'll fix or replace it, and if we can't make it work as described, we'll refund you. Bought the wrong edition by mistake? Message us before you start entering data and we'll sort it out. If the item isn't as described, Etsy buyers may also be covered by Etsy's Purchase Protection.

Yes — that's what it's for. Your licence covers one reselling business: you, plus people who work directly in that same business (a spouse, a partner, an employee entering data into your copy). It does not cover sharing the files or the Sheets link with other sellers, resale groups, or anyone outside your business, and the files themselves can't be resold or redistributed. Running two separate businesses? Message us about a discounted second licence.

The flagship's fee engine covers eBay, Poshmark, Mercari, Etsy, and Depop. If you sell somewhere else, the inventory and dashboard tabs still work, but that platform's sales would need fees entered manually — honestly, that removes the main point of the system, so we'd say don't buy it until or unless we add your platform. Single-platform sellers: the system works fine on one platform alone (the dashboard just shows one platform), and we also offer platform-focused editions in the shop if you'd rather have a narrower tool.

On Etsy, three usual causes: (1) The Etsy app can't download files — sign in to Etsy.com in a browser, go to You → Purchases and reviews → Download Files. (2) Payment is still processing — the download button un-greys once payment confirms, usually a few minutes. (3) The Excel file is inside a .zip — unzip it first (double-click on most computers). On Gumroad, your files are in your Gumroad library and in your receipt email. Still stuck? Message us through Etsy or Gumroad with your order number and we'll walk you through it. We reply within 1 business day, Monday–Friday.

In the Sales Log, delete the sale's row — or, to keep a record, set its Sale price to $0 and write REFUNDED in the Notes column — then set the item's Status back to Listed in Inventory. Don't enter a negative price: the fee engine can't price a negative sale and the numbers come out wrong. This works because on a full refund the platforms refund most of their fees too, so removing the sale is close to the truth — the one exception is eBay's per-order fee ($0.30/$0.40), which eBay keeps, so a refunded eBay sale's true cost is roughly that per-order fee. Partial refunds are approximate: lower the Sale price to what you actually kept and note it. (The same guidance is in the workbook's Start Here tab.)
