Built by a reseller, for resellers.
Flip or Pass exists because every other “profit calculator” we tried gave us numbers without an answer. We wanted a verdict.
The problem
Flipping on eBay isn't hard math, but it's annoying math. Final value fees vary by category. There's a per-order fee that depends on the price band. Promoted listings, returns, shipping, the cost of the item itself. Every variable is real, and getting any one of them wrong by a few percent flips a profitable buy into a money loser.
Most calculators online use a flat 12.9% fee assumption. That's fine for a back-of- napkin guess. It's wrong for trading cards, sneakers, electronics, and just about every other category we actually shop. So we'd be standing in a thrift store with a $4 price tag, doing fee math in our head, second-guessing ourselves, and walking away from things we should have bought.
What Flip or Pass does differently
We pulled eBay's actual fee schedule for over 50 categories and built it into the calculator. Every search, on every plan, is priced off real sold listings so verdicts are based on what items actually sell for, not what sellers wish they sold for. When an item has no recent sales, we fall back to live listings from eBay's Browse API and tell you that's what you're looking at.
And we made it give an answer. FLIP, PASS, or MAYBE. Not a spreadsheet of inputs. Not a chart you have to interpret. A verdict you can act on while still standing in the aisle.
The AI photo scan is the part we're proudest of. Snap a photo of an item (a vintage radio, a sneaker, an old controller) and the model identifies it (brand, model, era), then automatically searches for comparables. No typing. Pull out your phone, point at the thing, get a verdict.
Who's behind this
Flip or Pass is built by an active eBay reseller. The product comes out of years of buying, listing, and learning the hard way which items are worth flipping and which ones eat your weekend. Every fee schedule, verdict threshold, and edge case in the app traces back to a real listing that taught us something.
We ship updates constantly, talk to users directly through our contact page, and treat feedback as the single most valuable input we get. If you flip on eBay and something in the app feels off, tell us. The roadmap gets shaped by people who actually use this thing.
Try it
Free accounts get 5 verdicts a month, and they are the same verdicts Pro gets: real sold-price data, full fee math, AI photo identification, every comparable we found. Pro is $9.99/month and takes that to 50 a month, with a 7-day free trial.
