Vendoo
One inventory list that crossposts and syncs sales, including Whatnot (beta)
Vendoo is a multichannel listing manager for resellers. It keeps one inventory list, pushes items to many marketplaces, and pulls sales back so sold items come off the other channels. Its official help center documents Whatnot import, crosslisting and sale detection, but labels the Whatnot integration as beta.
Key features
- Crosslisting from one listing form, with Whatnot among the destinations.
- Bulk importer that pulls your active Whatnot listings into Vendoo.
- Sale detection that delists sold items from other marketplaces; for Whatnot, your computer must stay on.
- Bulk actions, multi-quantity listings, and offer sending.
- Analytics, plus size chart, fee and profit margin calculators.
- Web app, plus iOS and Android apps.
Who it's for
Resellers selling across several marketplaces who want one dashboard for inventory, not a Whatnot-only tool.

Learned this one the hard way: Vendoo only catches Whatnot sales while your computer is on and connected. I closed my laptop after a Sunday show, a pair of boots sold on Whatnot overnight, and they were still live on Poshmark in the morning. Nobody bought it twice, but it was close. Now the laptop stays on during busy weekends and I check the Sold tab before going live. Their help center still calls the Whatnot integration beta. Otherwise it has been solid for me.
@Ben same thing happened to me with a jacket. I leave an old laptop plugged in now just for this.
@Lucy The help article I read was the Whatnot one, so that's the one I can speak for.
The bulk importer was the reason I stayed. Hit Get Latest Items and my active Whatnot listings showed up in Vendoo, so I didn't have to retype anything.
Starter is $14.99 and already covers every marketplace, Whatnot included. I tried Growth for a month and didn't use the extra stuff, so I went back down.
Saves me a lot of time cross-listing and the interface is easy. Starter has been enough for me for a year.
Fine overall, but I'd rather control delisting per sale myself, and some settings are hard to find.
Love it. I use it to cross-post my Poshmark and eBay items straight to Whatnot. 🙌
Sale detection on Vinted missed a few items and I had listing errors after disconnects.
