After item cost, fees, postage and packaging. Before overheads and tax.

Illustrative example: one made-up jacket from photos to profit. Fees are the seller's own figure, not a platform rate.

A £20 sale is never £20.

Stock, fees, postage and packaging all come out before anything is yours. Most sellers never see the real number, so they overpay for lots and keep listing things at a loss. Try it with your own last sale.

Why I built this

I've sold clothes on eBay, Vinted and Depop alongside a full-time job. The selling was never the hard part. It was the evenings typing listings, and never really knowing what I'd made once the fees, the postage and the cost of a bulk lot came out. Some months it barely felt worth it.

Profit OS is the app I wanted: snap the item, get the listing, and see the real number on every sale.

  • Shows what you really madeEvery sale after fees, postage and packaging, this month's profit, what needs doing today, and your tax-year records in one export.
