Whatnot shows move fast. Your numbers should too.
Auctions close every ninety seconds and nobody can type accurately at that pace. The Streamalytix Chrome extension logs each sale as it closes, applies your real cost basis — including pallet and mystery-box inventory — and keeps net profit on screen the whole show.
- Auction-aware: logged at final bid
- Giveaway toggle so free items don't skew margin
- Whatnot fees and shipping applied to net profit
- Bundled orders grouped with proportional allocation

The auction format is exactly what breaks spreadsheets
Variable closing prices, mixed sourcing, giveaways, bundled shipping and multiple hosts — all in a two-hour window where nobody has a free hand.
- 01Prices aren't fixed
Every lot closes at a different number, so cost-to-price margin has to be calculated per sale rather than assumed from a price list.
- 02Sourcing is mixed
A single show can include single-unit SKUs, pallet items and mystery boxes. Each needs a different cost model to produce comparable margins.
- 03The pace is unforgiving
By the time you'd finish typing item 40, item 45 has already closed. Automation isn't a convenience here — it's the only accurate option.
The extension keeps up with your auction pace
It watches your own seller dashboard and writes a costed sale the moment a lot closes — item, final bid, quantity and buyer — with the cost basis attached.
- Installs in about 30 seconds, no Whatnot API access needed
- Auto-connects to the active show and shows credits left
- Giveaway toggle zeroes winning bids on free items
- Missed something? Add it manually from the live page
Bulk sourcing, real margins
Most Whatnot sellers buy at least some inventory by the case or pallet. Bulk lots divide landed cost — including freight — across units and draw down as items sell.
- Blended per-unit cost including freight and fees
- Remaining-unit tracking with over-sell protection
- Upload the supplier invoice and let AI build the lot
- Cost snapshotted per sale so restocks don't rewrite history
A per-show P&L and a map of your best Whatnot hours
Whatnot rewards consistency at the right times. The 168-hour heatmap shows when your audience actually buys, and category analytics show what to keep sourcing.
- Per-stream P&L after fees, shipping, COGS and host pay
- Item-level margin with visible cost source
- Peak hour heatmap across the full week
- Branded PDF exports for partners or bookkeepers
