Why HAMMR

Generic tools don’t know what a live show is. HAMMR is built around it.

E-commerce inventory apps see orders. Live auction selling is shows — hundreds of units moving in an evening, sold by voice, reconciled by hand. That is the exact workflow HAMMR was built for, because it was built inside a live auction business that runs on it every day.

The 2 a.m. spreadsheet

The stream ends and the real work starts: screenshots, chat replays, and a spreadsheet that says the night went great. Probably.

Average-cost fiction

Averaged COGS drifts a little with every restock at a new price, until the margin on your dashboard is a number nobody can defend.

A duct-taped stack

One app for inventory, another for orders, a notebook for host commissions — and no two of them agree on what actually sold.

Features

Everything you need to run the show

From the pallet hitting your dock to the payout hitting your bank — one system that keeps the story straight.

The live show workflow

Stage pallets to the set, sell in real time, reconcile what came back, finalize the show. The whole run-of-show is first-class — not a hack bolted onto a product catalog.

True cost, not averages

A FIFO cost ledger sits under every bin, so each sale carries the exact cost of the unit that left the building. Profit per show is real, down to the penny.

TikTok Shop, built in

Connect your shop and orders pull in automatically during the live, matching themselves to sales by auction number. CSV and XLSX upload cover every other platform.

Shopify, kept in sync

Inventory pushes on every stage, sale, and unwind. Orders pull on a 10-minute loop. Sync errors surface as alerts instead of drifting silently.

Forecasting & reorder alerts

Days-of-stock left on every product, reorder points that respect supplier lead times, and on-order tracking that quiets the alert once the truck is already coming.

Built for your whole crew

Admin, manager, host, and staff roles. Hosts see their own shows and commissions, staff scan and stage — and only the people you choose ever see costs.

How it works

Show night, start to finish

1

Stage

Wheel pallet bins to the set or scan manifested items in with the barcode scanner. HAMMR knows exactly what is on the floor before you go live.

2

Go live & sell

Log sales as fast as the auctioneer talks. TikTok Shop orders attach themselves to your sales while the stream is still running.

3

Reconcile

Count what physically came back. HAMMR works out what sold, depletes inventory oldest-cost-first, and pins the exact cost to every sale.

4

Finalize

Drop in your payout file and the show lands in your ledger: revenue, platform fees, true COGS, and net profit for the stream.

True profit

Profit you can defend

Every bin in HAMMR sits on a cost ledger. Restock at a new price and it becomes a new layer — it never smears into an average. When a unit sells, it sells at the actual cost of the oldest stock on hand, and that cost is stamped on the sale forever.

  • Restocks at new prices never distort the cost of what you already own
  • Refunds and un-sold items go back at their true cost, so valuation never drifts
  • Every profit number traces back to the exact units behind it
  • Manifested items? Each piece carries its own cost and barcode instead

AI built in

Your business, on speaking terms with AI

HAMMR is a native Claude connector. Link it once and ask questions in plain English — no exports, no copy-pasting numbers into a chat window.

And it is read-mostly by design: AI can analyze your inventory, shows, and profit, but it cannot sell, delete, or touch your cost basis. Your books stay yours.

Run your next show on HAMMR

Set up your business, load your first pallet, and know your real profit by the time the stream ends.
