Welcome to LASI

LASI (Live Auction Seller Intelligence) is the back office for sellers who run live auctions on TikTok Shop. It keeps track of your stock, runs the work around every show, pulls your TikTok orders in, helps you pack and ship them, handles what comes back, and tells you what each stream really made after fees, shipping and the cost of what you sold.

Most live sellers start with a spreadsheet, the TikTok Seller Center and a lot of memory. LASI replaces the spreadsheet and fills in what Seller Center does not tell you: which bin a sale came out of, what that unit cost you, how much of the payout is still on its way, and which host sold what.

You may still see the name HAMMR in older messages or links. That was LASI’s earlier name; it is the same product.

LASI is built for a live-auction business with a team: an owner who needs the real numbers, a manager who runs the day, hosts who stream, warehouse staff who stage, pack and ship, and customer service agents who answer buyers.

• Owners (admins) see everything — inventory, sales, costs, profit, payroll and every setting.
• Managers run operations and see sales revenue, but not costs or profit.
• Hosts run their shows, close out their own, and see their own commission.
• Staff stage, scan, sell, count back, pack and receive stock — with no money shown.
• Customer service works TikTok returns and replacement requests, and nothing else.

Every login sees only what its role allows, so you can hand the warehouse a login without handing it your margins. The full breakdown is in Your team and roles.

Everything in LASI hangs off one loop. Each stage has its own part of this guide.

1. 1Stock in. You add what you bought — a pallet of one kind of thing, or barcoded items one by one — with what it cost. A supplier invoice can arrive as an incoming order and become stock when the truck does. See Inventory, The catalog and Incoming orders.
2. 2The show. You create a show, sell live on TikTok, and record what sold — before, during or after the stream, depending on how you work. See Shows.
3. 3Finalize. Closing a show turns it into sales: revenue, fees, cost of goods and host commission land in your reports. See Finalizing.
4. 4Pack. At the packing bench you scan a sold item’s sticker and its shipping label prints. See The packing station.
5. 5Ship. Labels come from your shipping software, TikTok, or LASI itself. See Shipping.
6. 6Returns. Buyer returns, cancellations and replacements are answered and received back into stock. See Returns and Replacements.
7. 7Money. Sales, the P&L, TikTok’s real fees and the cash on its way to your bank. See Finance and TikTok fees.

LASI tracks stock in two shapes, and you can use both at once.

On the Inventory page these are the Pallets and Items tabs. Most TikTok auction sellers sell mostly from bins; barcoded items are for stock you count one piece at a time.

You rarely buy a bin’s contents at one price. You buy 100 blankets at $3.80 this month and another 100 at $4.25 next month, and they go in the same bin. LASI keeps each purchase as its own cost layer and, when a unit sells, takes it from the oldest layer first. Accountants call this FIFO: first in, first out.

That is why a bin’s cost per unit on screen means the cost of the next unit to sell, not an average. When the oldest layer runs out, the figure moves to the next layer’s price. Each sale keeps the exact cost of the units it took, so your profit is right even when the bin mixes several buys.

A show that starts at 9 PM and runs past midnight is still one night’s show. LASI groups everything by your business day — the calendar day in your business’s own timezone, set in Settings → Business → Timezone. Show dates, daily sales, the P&L and every “today” in the app use it.

It does not follow the clock on the computer you are using. A manager travelling in another timezone still sees the same days as the warehouse.

Every show starts from Auctions → New Show. The form asks one question — When are you recording sales? — and the answer picks how the show runs.

Whichever you pick, a show ends the same way: it is finalized.

Counting a show back moves the stock. Finalizing it is what turns it into sales in your reports: the gross from TikTok, the fees, the shipping buyers paid, the cost of what sold, giveaways, and the host’s commission. Until a show is finalized, the Sales and Finance pages show no revenue for it.

When you finalize, LASI usually already knows the gross, because the show’s TikTok stream is linked to it. The fee is an estimate at your shop’s rate at that moment; LASI replaces it with TikTok’s own figures as they arrive over the following days (see TikTok fees).

More in Finalizing, show reports and fixing a show.

• Revenue comes from finalized shows, TikTok orders and Shopify orders, all in one sales record.
• Cost of goods comes from the exact cost of the units each sale used (the cost layers above, or a barcoded item’s own cost).
• TikTok fees start as an estimate and are corrected to TikTok’s figures as orders settle.
• Shipping is what buyers paid for shipping against what your labels cost.
• Losses — damaged, missing, replacements sent — are their own line, never hidden inside a sale.

A figure LASI cannot know yet shows as a dash, never as $0. A $0 would read as “free”; a dash reads as “not known yet”.

There are five roles: Admin, Manager, Host, Staff and Customer service. Money is the dividing line. Admins see profit and costs; managers and hosts see revenue (a host only for their own shows); staff see no money at all; customer service sees only the refund amounts on the returns it answers. Each role’s sidebar only lists the pages it can open. The full table is in Your team and roles.

LASI comes in three pieces that share one account and one set of data.

• Search — the search box finds a word wherever it appears in the guide, including button names. Type the label you see on screen.
• Chapters — the guide is in parts that follow the order you meet things: start here, inventory, shows, packing and shipping, streams, after the sale, money, apps, and your account.
• Paths are written click by click, like Settings → Business → Timezone.
• “Who” under a section title means only those roles can do it. If a button described here is missing for you, your role probably does not include it.
