The Business Tool For Resellers
Scan the tag, take the payment, see the profit — before your next sale. One app runs your whole resale business — sourcing, inventory, and checkout — for resellers who sell in person or online.
Free to start · No credit card required
This is the actual analytics page — every number flows in from your sales as they happen.
Your entire business system in one place.
Five moves, beginning to end — and everything in between. SKUs, listings, storage spots, the math: Yanni takes care of it on its own.
Know where every piece came from.
Batch-print a sheet before an event. Scan any tag and Yanni rings it up in one tap.
The second it's paid: +$100.00 profit, logged — cost and fees already in the math.
Try the payment methods — the QR link updates.
The whole POS, in your pocket.
Point your camera at a label and the sale is half done. yanni.app runs full-speed in your phone's browser — no download, no App Store, nothing to update.
Label foundThe rack, the bin, the label — tracked.
Know which buys pay off
Tag every item with where it came from — a thrift store, an estate sale, a seller on Whatnot or Depop. Yanni ranks your profit by source.
Every item knows where it lives
Racks, bins, shelves — assign a spot once and never dig through tubs looking for the thing you just sold.
Create labels for selling
Batch-print QR labels before an event — Rollo and Dymo ready, six thermal sizes. Scan any label and it rings up in one tap.
A showroom link for buyers
Share one link and buyers browse what's still available — it updates itself every time something sells.
And the whole back office, too.
Free up to 50 items. Reseller — $14/mo unlocks the POS, labels and analytics.

“Google Sheets and my Notes app could only take me so far.”
I'm Johann. I've been collecting and thrifting vintage since I was 17. When I committed to reselling and trading, I ran the whole operation out of a spreadsheet and my notes app. It worked, but then I hit a wall. Everything got cluttered, I couldn't be consistent, I lost in trades, made bad purchases, and even got inventory stolen but couldn't tell which item it was. I was running the whole thing from memory.
I'm a data scientist and programmer by trade, so I built the system I wished I'd had since the beginning — field-tested at the Rose Bowl, on Whatnot, and at in-person events like ThriftCon. It works. I grew. What was missing, I built — and I'm still building. Now it's not just mine.
