The app can do basic integration. Orders come in Lazada and show in Shopify. I have noticed though that the inventory is not always updating. But all-in-all it can do the work, However, the biggest issue is that customer support is very poor, done only via email (yes, like its 1999) and in a 2 days answer cycle (like stores can wait so long). For example, the synchronization of the orders suddenly stopped working, so after 2 days you get an answer which doesn't solves the issue, a follow up is not even been answered. There is the issue of products variation and the mis-matched with Lazada, I get it that its a problem, but the customer support doesn't offer any creative way to go around it, so these products can be synced. Though I would suggest at least to push one SKU, but their system seems to not allow it. Great potential, with decent customer support, it can probably work more efficiently.

Integration with Lazada is tedious. Shopify provides multiple variants but if those variants do not match Lazadas predetermined variants by product type then you spend hours trying to fit into Lazadas categorization . Uploading is inconsistent in terms of speed so actually you are not quite sure if the changes are done.
Customer service is only by email and they take up to 1.5 days to respond and getting exact resolution to a problem is tedious and overall the process is slow and excludes any weekend support.
Frustrating slow and to actually to pay USD 18/ mth is a bit rich considering the limited support turnaround time and many of the functions are not fully compatible

App is very good with Lazada and does all functions listed. It's not the same case with Shopee though, I am still waiting for them to fix it, Shopee is on "beta" according to their app maybe its still under development, you can't sync anything to Shopee so it's totally useless. If I were rating this with just lazada on mind I'd give it a 5.. Once shopee is fixed I'll update my review and give 5 stars
