Multichannel
Inventory Management

Sync inventory across eBay, Whatnot, Shopify, Amazon, and more. Prevent overselling, manage all channels from one dashboard, and streamline your multichannel selling workflow.

Multichannel Inventory

One inventory. All your channels.

Selling on multiple platforms shouldn't mean managing multiple spreadsheets. BizInv connects your channels and syncs inventory in real-time — so you always know what's available, everywhere.

Platform Support

eBay ↔ Whatnot ↔ Shopify ↔ Amazon

Connect all your channels — eBay Live, Whatnot, Shopify, Amazon, Poshmark, and more. We're constantly adding new integrations.

Unified Dashboard

Manage Everything in One Place

See inventory across all channels from a single dashboard. Filter, sort, and take action without switching between platforms.

Multichannel selling is powerful — but only if your inventory stays in sync.

The biggest risk of selling on multiple platforms is overselling. BizInv's real-time sync eliminates that risk, so you can expand your reach without expanding your headaches.
