With Avalara integration enabled, if you do a bill run and a customer's address is unable to be validated by Avalara, an error for tax is returned to Zuora and Zuora cancels the invoice/bill run. When you have tens of thousands of customers this results in a few customers not getting invoices in certain scenarios because their address is malformed. We can do a lot of work in various places to fix address formatting, but it would be better if Zuora had an option on how to treat Avalara errors. Processing the invoice with simply 0 tax would be better than not processing it at all.
