I use the latest 1.5.9 version.
I live in Quebec Canada and in most province in Canada there is 2 mandatory taxes:
GST (5%) + PST (9.975%)
I’m a new user and I was adjusting the settings and in the taxes tab I found no way to have 2 taxes by default and I don’t want to ad a second taxe manually for each invoice it would defeat the purpose of automating my invoicing process.
Also I need 3 decimals we can’t round it to 2 decimals for the 9.975% of the provincial taxes
I’m pretty sure there is some way to automate it and to use 2 taxes by default but I did not found anything about it in the documentation so I need help.

@Severenth Could you help me on this one ?
