Connect Shopee and Lazada in under 10 minutes with OneCart's guided setup.
Shopee and Lazada are the two largest marketplaces in Southeast Asia, and most sellers run both at once. Kept separate, they mean duplicate listing work and constant stock juggling between two seller centres. OneCart links a Shopee shop and a Lazada store so one inventory pool feeds both and every order from each marketplace lands in a single dashboard.
Shopee and Lazada draw from one stock pool in OneCart. When a unit sells on Shopee, OneCart reduces the matching SKU on Lazada, and the same applies in reverse, so the item is not sold twice across the two marketplaces.
Orders from both Shopee and Lazada are brought into OneCart automatically and land in a single dashboard, so you work one order queue instead of checking two seller centres.
Create listings for both from Listings > New. Shopee's own rule limits titles to 10 to 120 characters and OneCart converts the Shopee description to plain text and replaces the '&' character, while Lazada accepts HTML in the description. Map the Variant SKU in OneCart to the SKU in Shopee and the Seller SKU in Lazada.
Connect Shopee first: 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.
Connect Lazada using its 2024 method, which has more steps. Open the Lazada Marketplace page for OneCart in your store's country, select 'Authorization Only' and 'Half a year', agree to the terms, then enter your Lazada Seller Centre login. If you run multiple Lazada stores, repeat this for each one.
Create listings on both from Listings > New. Shopee's own rule limits titles to 10 to 120 characters, and OneCart automatically converts the Shopee description to plain text and replaces the '&' character so it is accepted. Lazada accepts HTML in the description. Map the Variant SKU in OneCart to the SKU in Shopee and to the Seller SKU in Lazada.
When a unit sells on Shopee, OneCart reduces the matching SKU on Lazada in real time, so the same item is never sold twice across the two stores.
Lazada authorisations expire. If Lazada Seller Centre shows an expiry date that differs from OneCart, the yellow Update Lazada Expiry Date button on the shop's Settings page in OneCart brings them back into line.
Everything you need to know about connecting Shopee and Lazada with OneCart.
No. Shopee authorises in one pass inside Seller Centre. Lazada's 2024 method is longer: you open the Lazada Marketplace page for OneCart, choose Authorization Only and Half a year, accept the terms, then log in. Each Lazada store has to be authorised one by one.
Lazada supports HTML in descriptions. For Shopee, OneCart automatically converts the description to plain text and replaces the '&' character, and Shopee's own rule limits titles to between 10 and 120 characters.
Lazada is connected per store using its 2024 method, where you open the Lazada Marketplace page for OneCart in your store's country, so you authorise each regional store on its own. Shopee is authorised inside Shopee Seller Centre. You can run multiple stores of each and manage them together.
Yes. Because both marketplaces share one stock pool in OneCart, a sale on one reduces the matching SKU on the other, and if stock would go negative OneCart sends zero. This helps stop you promising units you have already sold.
