How to sync stock between Shopee and Lazada
To automate your stock syncing between Shopee and Lazada, connect both stores on Indexync and import the listings via Indexync's smart matching, which auto maps your existing listings and pushes the source store's stock to all your connected stores. Inventory is adjusted whenever a sale happens on either marketplace and syncs to all connected stores in real time on Pro and Scale, and every five minutes on Free and Lite.
What are the four ways to keep Shopee and Lazada stock in step?
There are four ways to keep Shopee and Lazada stock in step: update both Seller Centres by hand after every sale, split your stock so each marketplace gets its own share, hold back a safety stock buffer, or connect both shops to one stock count with a tool. The first three are free and cost you either time or sales.
| Update by hand | Split your stock | Safety stock buffer | One stock count | |
|---|---|---|---|---|
| What it costs | Free | Free | Free | A monthly fee, from S$19 |
| Daily work for you | You retype the stock number in both Seller Centres after every sale | You move units between the two shares as demand shifts | None | None |
| Does it stop overselling? | No, especially for fast moving items e.g. multiple units sold within minutes | Yes, because neither marketplace can sell more than the share you gave it | Mostly, the units you held back cover the gap until they run out | Yes, once the tool has updated your other shops, so it depends how fast that tool is |
| How much of your stock can you sell? | All of it | Less, because each marketplace only ever sees its own share | Less, because the units you held back sit unsold | All of it |
| Covers you overnight? | No | Yes | Yes | Yes |
All three free options work while you are selling a few orders a day. They stop working when Shopee and Lazada sell the same unit before you have noticed the first sale, and that is most likely on a campaign day like 11.11 or during a flash sale. The guide on how to stop overselling across marketplaces sets out each option and what it costs you.
How do you set up stock sync between Shopee and Lazada?
Set up in 15 minutes: connect both Seller Centre accounts to Indexync, review the matches Indexync suggests between your Shopee and Lazada listings, and import the matched products. Those same three steps are all it takes to sell on Shopee and Lazada at the same time from one place, because the two catalogues become one catalogue after the import.
- Connect each shop in Settings, under Connections. You approve the connection on Shopee’s and Lazada’s own Seller Centre login, so Indexync never asks for a shop password.
- Review the matches. Indexync suggests which Shopee and Lazada listings are the same product, so most products are matched for you before you look at them.
- Import the matched products. Nothing on your shops changes until you approve the matches, and you can also match any product yourself.
Indexync is plug and play: there is no setup project, no training and no tutorials to watch. If you can use a Seller Centre, you can use Indexync.
How does Shopee and Lazada stock sync work after a sale?
A Shopee sale reduces your Lazada listing as the sale happens, in real time on Pro and Scale, because Indexync acts on the order push that Shopee and Lazada send rather than waiting for a scheduled check. On Free and Lite the update runs every five minutes.
How quickly a tool hears about the sale is what decides the speed, not how fast it writes the new number. A tool that waits for a scheduled order pull can only update your Lazada stock after the next pull runs, and that is why those tools describe their sync as a cycle of minutes or hours.
The gap between a sale and the next scheduled pull matters most when both marketplaces are busy at the same time. On a campaign day like 11.11, five minutes is long enough for Shopee and Lazada to sell the same unit.
What if the same product has different names or SKUs on Shopee and Lazada?
Indexync matches your Shopee and Lazada listings via its smart matching logic, so most products are paired for you before you review. If a product has a completely different name and SKU on Shopee and Lazada, Indexync does not guess: you match those yourself, once, during the import.
Nothing is changed until you approve the matches. Indexync suggests which listings are the same product, and you review and approve.
What about pack sizes, bundles and safety stock?
A safety stock buffer, units you hold back so the marketplaces see fewer units than you own, is available on every Indexync plan: keep 10 of 100 back and Shopee and Lazada each list 90. Custom sync rules and bundles are on Pro and Scale.
- Custom sync rules link stock across different listings. Sell one 100g pack and the 50g listing drops by two, because the 100g order is fulfilled as two 50g units.
- A bundle is built from several products, and it sells only as many as its scarcest component allows, so the bundle listing cannot oversell a part you have run out of.
- Stock allocation splits your stock per store, where you want your Shopee store and your Lazada store to hold different amounts.

What else changes once Shopee and Lazada are connected?
Stock is one of the four jobs Indexync does in one workspace: listings, automatic inventory sync, one order queue and cross-channel analytics. Connecting both marketplaces means you stop opening two Seller Centres to do the same task twice.
- Listing Management. Edit a product once and both marketplaces get the change, one product or the whole catalogue in bulk, with Lazada free to keep its own title, price or photos.
- Order Management. Every Shopee and Lazada order lands in one queue with one status set, with combined pick lists across both. You batch ship on Shopee and Lazada, and you print shipping labels in bulk on both marketplaces merged into one PDF, on Lite, Pro and Scale.
- Cross-Channel Analytics. Cost prices, margin and profit per store and per SKU, with seller payouts and fee breakdowns beside them, on Pro and Scale.
- Sellers on Indexync get back 10+ hours a week.
When you are ready to sell on a new channel, Indexync builds the new listings automatically, so expanding does not mean retyping your entire catalogue. The guide on how to copy listings between Shopee, Lazada and TikTok Shop covers that step, and the Shopee and Lazada integration page shows the pair in the product.
