Connect TikTok Shop and Shopee in under 10 minutes with OneCart's guided setup.
TikTok Shop turns short-form content into checkout, and Shopee gives you a settled marketplace crowd across Southeast Asia. More sellers now run both, and kept apart they mean listing the same products twice and chasing stock between two seller centres. OneCart links a TikTok Shop and a Shopee shop in one account so a single stock pool drives both and orders from each land in one dashboard, with your other channels manageable from the same place.
OneCart holds the source-of-truth quantity and pushes stock to your linked TikTok Shop listings whenever a quantity changes, including a sale on Shopee, while Shopee shares the same pool. If stock would go negative it sends zero, which helps prevent overselling.
Orders from TikTok Shop and Shopee are brought into OneCart automatically and land in one queue. TikTok orders are collected by polling roughly every ten minutes, and you can force an immediate refresh in the app when you need it.
Cross-post to TikTok Shop from OneCart, where a category is required, so you choose one before submitting and set the main image, with any extra images added a few moments later. For Shopee, OneCart converts the description to plain text, replaces the '&' character, and keeps titles within Shopee's 10 to 120 character limit.
Connect TikTok Shop: in My Platforms, click the TikTok Shop Connect button. You are taken to TikTok Shop's authorisation page, where you log in to your TikTok Shop seller account and approve OneCart's access. TikTok returns you to OneCart and the store connects. OneCart automatically brings in your recent TikTok orders, the last six months by default, so past sales appear, and those backfilled orders do not change your stock.
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. A confirmation banner appears once Shopee is linked.
List on both from one product list. TikTok Shop requires a category for every product, so choose one before you submit, set the main image, and OneCart sends each variant with its price and quantity. For Shopee, OneCart converts the description to plain text and replaces the '&' character, and Shopee's own rule keeps titles within 10 to 120 characters. Map each Variant SKU in OneCart to the SKU in Shopee.
Build a product once in OneCart and create it on Shopee from the same screen, so a line that takes off on TikTok Shop can reach Shopee's marketplace audience without re-entering catalogue data in Seller Centre.
OneCart holds the source-of-truth quantity, so a sale on TikTok Shop reduces the matching SKU on Shopee and the reverse holds too, which keeps a single unit from being sold twice across the two marketplaces.
