I have one customer who is set up that clearly has the Tax Code and HST setup properly in their customer file, but consistently it does not use those code when creating invoices. Every time I create an invoice and it misses the HST, I check the customer record and it is correct and the same as all the others. Any ideas why this is happening?

Hello Sue,

Edit the Customer record and check for Ship to Addresses on the Contacts/Shipto tab.

You may have a Ship to address with a Blank as the Ship to code.

If a Ship to address is being used, the Tax group and Tax type from the Ship to address will override the ones on the Customer's Invoicing tab.

Do you create an invoice by copying an older invoice?

Thank you for telling me to check the Ship/To info. That was exactly where the problem was.
