Automatic adding of TAX (VAT) when creating quotes

Don’t forget your Canadian customers Mostly Quebec ones) who are forgetten in the taxes, we have two taxes here. We try everything to have it works. We finally using a dummy client to calculate our taxes and doing a manual additions. Results of our missing taxes, the quotes integration with Quickbooks is not working with the Canadian versions. When we bought HS, all these appears as working is your publicities.
Results now, we spend 10k to be able to have it working and we are spending extra money to keep 2 others softwares we used to automate ours processes.
