Connect Lazada and Shopee in under 10 minutes with OneCart's guided setup.
Lazada and Shopee anchor most Southeast Asian sellers’ marketplace mix, and running both by hand means double the listing work and constant stock juggling between two seller centres. OneCart links a Lazada store and a Shopee shop so a single inventory pool drives both and orders from each marketplace flow into one dashboard. The two authorise in very different ways, and OneCart handles the differences for you.
OneCart drives both marketplaces from one inventory pool, so a sale on Lazada reduces the matching SKU on Shopee and the reverse holds too. Neither marketplace oversells stock the other has already moved.
Orders from both Lazada and Shopee are brought into OneCart automatically and flow into one dashboard, so you fulfil from a single queue instead of logging into two seller centres.
Create listings for both from Listings > New. Lazada accepts HTML in the description, while for Shopee OneCart converts the description to plain text, replaces the '&' character, and keeps titles within Shopee's 10 to 120 character limit. Map the Variant SKU in OneCart to the Seller SKU in Lazada and the SKU in Shopee.
Connect Lazada first using its 2024 method, which has the longer flow. Open the Lazada Marketplace page for OneCart in your store's country, select 'Authorization Only' and 'Half a year', agree to the terms, then log in to Lazada Seller Centre. Repeat for every Lazada store you run.
Connect Shopee: go to Settings > My Platforms > Manage Connections, open the Inactive Shops tab, click Refresh Shopee, log in to Shopee Seller Centre, and click Confirm Authorization.
Create listings for both from Listings > New. Lazada accepts HTML in the description, so you can format text and add images and links. For Shopee, OneCart automatically converts the description to plain text and replaces the '&' character, and Shopee's own rule limits titles to 10 to 120 characters. Map the Variant SKU in OneCart to the Seller SKU in Lazada and to the SKU in Shopee.
A sale on Lazada reduces the matching SKU on Shopee, and the reverse holds too, so neither marketplace oversells stock the other has already moved.
Lazada authorisations run out after their set window. When the expiry date in Lazada Seller Centre no longer matches OneCart, click the yellow Update Lazada Expiry Date button on the shop's Settings page in OneCart to realign them before sync is interrupted.
Everything you need to know about connecting Lazada and Shopee with OneCart.
Lazada's 2024 method requires several steps: open the Lazada Marketplace page for OneCart, choose Authorization Only and Half a year, accept the terms, then log in to Seller Centre, once per store. Shopee is a single authorisation inside Seller Centre from the Inactive Shops tab. OneCart supports both, just expect Lazada to take a few more clicks.
Not as-is. Lazada supports HTML, so rich descriptions carry over there. Shopee does not, so OneCart automatically converts the description to plain text and replaces the '&' character, and keeps titles within Shopee's 10 to 120 character limit.
Both are connected per store: Lazada through its 2024 method using the Lazada Marketplace page for OneCart in your store's country, and Shopee by authorising inside Shopee Seller Centre. You authorise each shop you run, so the regions you sell in are the ones you connect.
OneCart has plans for sellers at different order and SKU volumes, so the right plan depends on how much you sell. You can compare plans and what each includes at /pricing/.
