Your stock just went negative on Shopee MY. A Lazada MY buyer checked out ten minutes earlier, and neither platform knew about the other. Inventory stock software fixes that by keeping one live count for every channel. Here is what it tracks, how it works, and what to look for before you pick one.
What Is Inventory Stock Software?
Inventory stock software is a system that records how many units of each product you hold, where they sit, and how many are already promised to buyers. It keeps one shared count for every sales channel, so a sale on Shopee MY reduces what Lazada MY and TikTok Shop MY are allowed to sell.
Inventory stock software is a system that updates your stock count every time stock moves. A sale, a return, a supplier delivery, and a damaged-goods write-off each change the number. The software keeps that number in one place, instead of in a notebook, a spreadsheet, and three marketplace dashboards that disagree with each other.
You will also see it called stock control software or inventory keeping software. Same job: knowing what you have, and telling every channel the truth about it. Our guide to inventory keeping software covers the record-keeping side.
Three tools solve different problems, and sellers often mix them up:
| Tool | What it does | Fits when |
|---|---|---|
| Spreadsheet | Records stock changes you type in by hand | One channel, a short product list, low order volume |
| Inventory stock software | Tracks stock and syncs counts across channels automatically | Two or more marketplaces, or stock you cannot afford to oversell |
| Warehouse management system (WMS) | Runs the physical warehouse: bin locations, picking, receiving, staff tasks | You run a warehouse with staff and a set pick process |
A spreadsheet is a fine start, until you must update it by hand after every order on every channel. Our guide to inventory management in Excel shows how to set one up properly, and our warehouse management system guide covers the step beyond stock software.
What Stock Numbers Does the Software Track?
Good stock software tracks four counts for every SKU, not one: on hand, reserved, available, and incoming. Available stock is on-hand stock minus reserved stock, and it is the only number your marketplace listings should show to buyers.
A listing that shows “on hand” instead of “available” advertises units you have already sold.
| Count | What it means | It changes when |
|---|---|---|
| On hand | Units physically in your storeroom or warehouse | A delivery arrives, an order ships, or a stock count corrects it |
| Reserved | Units in orders that are paid or pending but not yet shipped | An order is placed, cancelled, or shipped |
| Available | On hand minus reserved. The number you sell against | Either count above changes |
| Incoming | Units on a purchase order that have not arrived yet | You raise a purchase order, or the delivery lands |
For illustration: 40 units on hand and 12 units in unshipped orders leaves 28 available. Every marketplace listing should show 28, not 40.
The software tracks each count per SKU, the unique code for each product variant. A black T-shirt in size M is a different SKU from the same shirt in size L. If your codes are a mess, the free SKU generator gives you one consistent format before you load anything in.
Better tools also value your stock. Multiply units by unit cost and you see the cash sitting on your shelves, in MYR (RM). The cost method matters: FIFO treats the oldest units as sold first, while average cost blends every purchase price. Ask your accountant which one your books use.
Software only knows what it is told. Damaged units, theft, and unrecorded returns pull the record away from the shelf, so keep counting on a rolling schedule, as our guide to the inventory perpetual system explains.
How Does Inventory Stock Software Sync Stock Across Shopee MY, Lazada MY, and TikTok Shop MY?
The software connects to each marketplace through its official developer platform, receives every new order, deducts the units from your shared stock, and pushes the new available count to every other listing. Sync speed varies by vendor, so ask for a published sync interval instead of trusting the word “real-time”.
Here is what happens behind the scenes:
- You connect each store. Shopee and Lazada both run official developer platforms, Shopee Open Platform and Lazada Open Platform, where approved apps ask permission to read your orders and update your stock.
- You map SKUs. Every marketplace listing gets linked to one master SKU in the software. Unmapped or wrongly mapped listings are a common cause of counts that will not match.
- An order arrives. The software reserves the units and lowers the available count.
- The new count goes out. Every other connected listing updates to the same available number.
- The order ships or comes back. On-hand stock drops when the parcel ships. If the buyer cancels, or a parcel returns through Ninja Van MY or Pos Laju, the units go back into stock only after you receive them in the software.
Step 5 is where counts drift. A returned parcel sitting in your storeroom but not received in the software shows as zero stock and sells nothing. Receive returns the day they arrive.
Three situations need a check before you trust any tool:
- Bundles. Selling two SKUs as one bundle should deduct one unit from each component, not from a separate bundle count.
- Campaign peaks. Sale days such as 11.11 and 12.12 send orders in bursts. Ask how the tool handles marketplace rate limits.
- Marketplace-held stock. Units in a marketplace’s own fulfilment warehouse are counted by the marketplace. Check whether the software reads them or ignores them.
How Do Reorder Points and Low-Stock Alerts Work?
A low-stock alert fires when a SKU’s available count falls to its reorder point. The reorder point is average daily sales multiplied by supplier lead time in days, plus a safety stock buffer. Set it per SKU, because a fast seller and a slow seller need very different triggers.
The formula is short:
Reorder point = (average daily sales × supplier lead time in days) + safety stock
For illustration: a SKU sells about 6 units a day, your supplier takes 10 days to deliver, and you hold a 20-unit buffer. The reorder point is (6 × 10) + 20 = 80 units. When available stock reaches 80, the software alerts you to order.
The buffer covers days when sales run above average or the supplier runs late. Our reorder point calculator and safety stock calculator apply the standard reorder point logic to your own sales and lead-time data.
Questions to ask about any tool’s alerts:
- Can you set a reorder point for each SKU, or only one level for everything?
- Does it use your real sales history, or do you type the numbers in?
- Where does the alert go: email, phone, or a dashboard you must remember to open?

Which Features Matter at Your Size?
Match features to your stage. One channel needs accurate counts and low-stock alerts. Several channels add SKU mapping and automatic sync. Stock held in a warehouse adds purchase orders, batch tracking, and valuation. Pay only for the stage you are in.
| Your stage | Must-have features | Can wait |
|---|---|---|
| Starting out, one marketplace | Accurate on-hand count, SKU list, low-stock alerts, CSV import and export | Barcode scanning |
| Selling on two or more marketplaces | Order import, SKU mapping, automatic sync, variant and bundle handling, a log of every stock adjustment | Per-channel stock buffers |
| Holding stock in a storeroom or warehouse | Purchase orders, supplier records, stock count tools, batch or expiry dates, a cost method (FIFO or average cost) | Multi-location transfers, a full WMS |
Ginee, Sellercraft, and Anchanto are the three tools Malaysian sellers most often compare, based on vendor documentation and seller community feedback. Ginee is a common first step off spreadsheets, Sellercraft adds stronger supplier and purchase order workflows, and Anchanto suits multi-warehouse operations. Our Malaysia inventory management software comparison sets them side by side.
Before you commit to any of them, run this check:
- Channels. Does your plan support every marketplace you sell on: Shopee MY, Lazada MY, TikTok Shop MY?
- Money and support. Is pricing shown in MYR, and does support answer during Malaysian working hours?
- Exit. Can you export all your stock and movement data if you leave?
- Edge cases. How does it treat returns, cancellations, and bundle SKUs?
- Trial. Is there a free tier or trial, so you can test a handful of SKUs first?
How Do You Set Up Stock Software Without Breaking Your Counts?
Count your stock once, clean your SKU list, load opening quantities, and connect one marketplace at a time. Check counts against the shelf before adding the next channel. Connecting everything on day one leaves you with a wrong count everywhere at once.
Follow these steps in order:
- Do one full physical count. Count every SKU on the shelf, and note damaged units separately. This is your opening balance.
- Clean your SKU list. Use one code per variant. Retire duplicates, and align codes across your Shopee MY and Lazada MY listings.
- Load the opening quantities. Import your counts by CSV or type them in. Do this before connecting any store, or the first sync pushes wrong numbers to your listings.
- Connect one marketplace first. Run it for a week and compare the software’s counts with the shelf. Fix every mismatch before you add another channel.
- Add the remaining channels. Map SKUs for Lazada MY and TikTok Shop MY, then confirm that one test order lowers the count on every listing.
- Set reorder points for your best sellers. Start with the SKUs that bring in the most orders, then extend to the rest.
- Schedule cycle counts. Count a small slice of SKUs each week, and log every correction with a reason.

Frequently Asked Questions
What is inventory stock software?
Inventory stock software is a system that records every stock movement (sales, returns, deliveries, and write-offs) and keeps one shared available count for all your sales channels. For Malaysian sellers it connects to Shopee MY, Lazada MY, and TikTok Shop MY, so a sale on one platform lowers the stock the others can sell.
What is the difference between inventory stock software and a spreadsheet?
A spreadsheet only records what you type, so every order on every channel needs a manual update. Inventory stock software receives orders from the marketplaces directly and updates the counts itself. A spreadsheet works for one channel and a short product list. Once you sell on two marketplaces, the delay between manual updates is where overselling starts.
Can inventory stock software stop overselling on Shopee MY and Lazada MY?
It shrinks the window for overselling but cannot remove it. Orders placed inside the vendor’s sync interval can still oversell, so sellers keep a small buffer on fast-moving SKUs during campaigns such as 11.11 and 12.12.
Do I need a barcode scanner to use inventory stock software?
No. Barcode scanning is optional, and a small catalogue can run on order imports and manual entry. It pays off once you receive supplier deliveries or pick orders at volume, because scanning removes typing errors at receiving and packing.
How much does inventory stock software cost in Malaysia?
Pricing varies by vendor and plan. Some publish monthly MYR plans, some offer a free tier or trial, and enterprise tools quote per operation. Price follows order volume, channel count, and features such as purchase orders. Confirm current MYR pricing with each vendor.
