Stop guessing your profit. Know it instantly.
You flip items on eBay, Vinted, Depop, Poshmark. But at the end of the month, do you actually know how much you made?
eBay took fees. Postage cost more than you quoted. You bought mailers. Now it’s April and you owe tax — but you have no idea how much profit you actually made.
This spreadsheet ends that problem.
