Protect Your Inventory

Prevent
Double Selling During Live Shows

Real-time inventory sync across eBay, Whatnot, and more. Never sell the same item twice. Protect your reputation and your revenue.

Double Selling Prevention

Sell once, never twice.

Double selling is the #1 fear of live sellers. One item sold on two platforms at the same time means angry customers, refunds, and a damaged reputation. BizInv's real-time sync eliminates the risk — completely.

Core Feature Real-Time Sync

Instant Inventory Updates

When an item sells on any platform, BizInv updates inventory everywhere else within seconds. The item is gone before anyone else can buy it.

Multichannel Sync

eBay ↔ Whatnot ↔ More

Sync inventory across eBay Live, Whatnot, Shopify, Amazon, and Poshmark. Run shows on multiple platforms without the risk of overselling.

Safety Net

Near-Simultaneous Protection

Even if two orders happen at nearly the same time, BizInv catches them. The second order is flagged so you can handle it before it becomes a problem.

Double selling kills trust. BizInv protects it.

Your customers trust that what they bought is available. When you double sell, you break that trust. BizInv's real-time sync ensures your inventory is always accurate — so you never have to make that awkward apology call.

How It Works

One sale, one inventory update.

When a sale happens, BizInv instantly deducts the item from your master inventory and syncs that change across every connected platform.

  • Sale happens on eBay Live
  • Inventory updates in milliseconds
  • Whatnot and other platforms sync instantly
  • Item is removed everywhere — no double selling

[ THE LIVE SELLER PROBLEM ]

Going live is exciting.
Double-selling isn't.

You list on eBay, go live on Whatnot, and hope nobody buys the same item twice. That's a gamble.

ERR · DOUBLE_SALE

“Sold on Whatnot — but still on eBay.”

You scramble to cancel. Angry buyer. Lost fee. Happens every show.

ERR · SHOW_PREP

“Where did I put that item?”

Pull 50 items for a show. Half unsold. Now you've lost track of what went where.

ERR · RECONCILE

“What actually sold tonight?”

After the show, a pile of unsold items and jumbled notes. No clean reconciliation.
