FlipMargin
In the workshopFees, margin & break-even
Store name: “Reseller Profit Calculator”
What it is
Works out a reseller's real profit before they list. Enter what you paid, your sale price, and shipping, and get an itemized receipt: marketplace fees, payment processing, net proceeds, profit, margin, ROI, and the exact break-even price.
Why we built it
Part-time flippers guess margins in their head or fight a spreadsheet at a yard sale, and the closest paid app has been abandoned since 2015. The hard part is fees that drift constantly, so every marketplace preset is a plain, editable table you can correct in seconds. The app never goes stale even when a rate card changes.
Want one like this?
FlipMargin is one of 87. We can build yours.
Every app on the shelf started as one honest problem, scoped small and built native, end to end. That’s exactly how we approach client work — designed, built and shipped, without the bloat.
