Invoices: Auto Tax works on pickup orders with no Ship To
When an invoice has no Ship To address because the customer is picking the order up, Auto Tax now calculates against the Bill To address instead of being skipped. Clearing Ship To on an existing invoice recalculates the same way, and the invoice records the address the tax was actually calculated from.
Auto Tax also recalculates when the billing address, the shipping address, or the customer changes, including on bulk invoice address changes. Invoices for customers who are not tax exempt, and invoices with no taxable line items, now explain the result inline.
