I think we need Shipstation to really address 2 major fallbacks. First one is that Shipstation for tax reasons for the US version cannot support ABN which is the tax code for Australia. Seems strange that Europe, US, and pretty much all elsewhere is supported but Australia which is a big issue for us handling international shipments.
The second issue is the API needs to be updated to handle populating the TAX ID and TAX Number. I assume these fields were all added later but no effort was made to update the API to handle the new fields that were created and we have to manually enter these values in.
