I've just setup an account with Avalara, I'm going to talk with a go live rep in a few days but want to get this done as quickly as possible, and there seems to be no documentation on how to do this. 

Within Odoo after installing the avatax module, there are additional fields for the contact "Avalara Code" which is not editable and has something like "Contact 99" as the value. It also has  "Avalara Partner Code" and "Avalara Exemption" both of which are blank. 

My understanding is there should be some way have Avalara recognize the customer the shipping address and compute tax based on whether or not they have an exemption certificate on file in avalara for that destination so that taxes can be computed correctly, it seems like the above fields allow mapping customers in avalara to odoo and vice versa. I think the tax exemption field is only intended as a work around if the cert isn't in avalara yet.

I'm confused about the workflow though, and what to put in the "Avalara Partner Code", do I need to create all my exempt customers in Avalara first or will the connector manage this? Is there an easy way to import my customers into Avalara? What is actually syncrhonized in terms of contacts/customers between Avalara and Avatax?
