Hey, @reeveswim
I’d be happy to help. With that said, can you provide some additional context in regards to the errors you are making and struggling with? Any particular screenshots or error messages would be useful.
With that said, DSers does have a comprehensive help center that covers all things order management here. This will teach you everything from placing an order from Shopify-Aliexpress to fulfilling orders from start to finish.
I hope this helps. If there is anything else I can help you with, please let me know.
