Hi there,
We sell products all across Canada.
As suggested in one of the forum questions, we decided to set up a separate tax group for each province that we sell to.

I set up a test customer and tried each tax table on it. Each time I changed the tax group on the customer and processed a test order, everything worked. The tax group on the header screen changed, etc.

Then we tried it on a few existing customers. The tax group was accepted when we edited the customer profile.
When I did a new order for the customer, the header screen showed the OLD tax group and not the new one.
The tax status is also wrong.
Is the a problem with changing tax groups on existing customers that you know of?

Look at the ship-to address used on the OE order. It contains a tax group and status that will over-ride whatever is set on the customer. You need to update your ship-to address codes to use HST tax groups as well as customers.

Thank you very much. When tested the tables we used 2 customers who had ship to addresses. Luck of the draw.

I changed them in the ship to address and everything works fine now.
Also tested on those who had no ship to's and they are fine as well.

Many thanks,
Sandy
