As answered by people managing Codility and PalmFlow.app.
PalmFlow.app's answer:
Every other tool makes you choose between knowing where your inventory is and knowing whether you made money. PalmFlow is the one that does both.
Against the crosslisters (Vendoo, List Perfectly, Crosslist, Nifty). They're built to get a listing onto ten marketplaces fast, and they're good at it. But ask them what a specific item actually earned you after the final value fee, the shipping label, and what you paid for it, and the answer is thin or absent. They treat accounting as a footnote. So resellers end up paying for a crosslister and keeping a spreadsheet — which is the exact situation the spreadsheet was supposed to end.
Against Flipwise. This is the honest one, because Flipwise nails profit tracking. Its limit is that it's eBay-only. The moment you sell anywhere else, your numbers are incomplete again — and almost every reseller sells in more than one place. PalmFlow tracks profit and pulls from more than one channel.
Against Sortly and generic inventory tools. They'll organize a warehouse beautifully and have never heard of a final value fee. A reseller's costs aren't just what they paid for the item, and a tool that can't model marketplace fees can't tell you anything true about a flip.
Against My Reseller Genie and the bookkeeping-first tools. They come at it from the accounting side and leave the live marketplace connection out. You end up typing in what already exists in your eBay account.
The concrete differentiators:
And the honest part, which is itself a reason to trust it: PalmFlow tells you what it doesn't do. Every integration is labeled Two-way or Import only, on the card and on the item, so you're never guessing whether an edit reached the marketplace. That habit is the actual product philosophy — a tool you use for money should never let you believe something that isn't true.
