Please help. I have built a store that sells products nationally, but sources supply from different suppliers in different areas.
1) I need to be able to offer the customer essentially a different user experience, different pricing, different products based on there geographic location.
2) I am using a Courier company that has a API. How do I build in this API into my store so that the customer can track their order as if my store was handling the delivery itself.
3) How do I auto generate Invoice numbers when order is paid for, with invoice number that links directly yo waybill from courier, etc...
Thank you for all the help
