--> Configuration for delivery country or for each shopinstance
--> Settings: Active and US or CA or US and CA.
Could Avalara always be requested? Or is caching of Avalara responses required (e.g. address-check?)
Info: The experience shows in average up to 10 getTax calls before order confirmation. In a straight-forward order entry process, the number of calls should be about three to five.
--> No caching necessary.
Which address is relevant for addressCheck ?
--> delivery address
How does Avalara calculate the tax rate with TaxIncluded "true" (Do we need transmit netprices?)
--> Tax included just tells Avalara, if the Avalara tax is included in the price (frozen price)
--> So net prices has to be transmitted. No "German" taxes included.
Which optional parameters can change the tax rates?
What could be a scenario to send original invoice date as tax calculation date for return orders/credit memos?
Should it be configurable?
Has the sender address influence on the calculated tax value?
--> no.
Which would be the relevant delivery address for virtual goods?
What should happen if address validations failed?
--> The transaction should be allowed to proceed even if they accept the invalid address as being correct.
How will the tax be calculated if the address is invalid?
--> not our business ;)
