It may says the item is delivered on tracking. But how can i sure that it was received by the buyer on our webstore.
What if i click Confirm Goods Received on AliExpress when the tracking says it is delivered, then a few days after my customer complaining that no order was delivered?
You don't have to confirm the order at Aliexpres at 1st place, that's not a wise move since you're selling, it will be automatically confirmed after the timeout.
Also, Aliexpress give you a period of 15 days after confirmation to open dispute in case your customer want to return the product.
Something else, when you send products with tracking, you don't have to stress yourself if it's delivered or not, shipping companies wont deliver unless the package is signed by the exact buyer, however it doesn't mean mistakes happens.
Good luck.
