The fee calculator and SKU generator, rebuilt
The fee calculator now leads with the answer: which marketplace leaves you the most on this item, and how much more than the next one. Underneath, all nine sit in order, and opening any of them shows where the money went — every fee line, the price you break even at, and the exact formula that platform charges.
- It's one page at every size now, so the phone version and the laptop version are the same thing rather than two designs that drifted apart.
- Want a particular profit rather than a particular price? Switch to Find listing price, tell it what you want to clear and what the item cost you, and it works backward to the minimum you'd have to list at on each marketplace.
- There's a proper reference under the calculator too: what all nine platforms charge in plain terms, why two "10% platforms" pay out differently, what margin, ROI and breakeven actually mean, and an honest answer on which marketplace is cheapest — including when the cheapest one isn't the most profitable.
- The SKU generator got the same treatment. Set your prefix, pick sequential, dated, category or a short random code, and build up to 500 at a time — copy them or take the CSV straight into a spreadsheet. Start number, padding, separator and letter case are all still there, one fold down.
- And a guide to go with it: the four formats side by side with real examples, why a SKU should never encode price or condition, which characters to avoid on a printed label, and where the code goes on eBay, Poshmark and Mercari.
- Both are free, at palmflow.app/fee-calculator and palmflow.app/sku-generator, alongside the eBay title optimizer.
