I use Avalara's Avatax sales tax engine to calculate sales tax on orders. The amount of sales tax is calculated based on where the goods are shipped to. When an order was shipped to an address that is not the customer's billing address, and then the items are returned for a credit, there is no way to create a credit memo with the original delivery address on it, so there is no way for Avatax to calculate the correct sales tax on the returned items. Please help!
