Never second-guess tax rates again. Cadig automatically calculates GST, HST, PST, and QST based on your client's province—including Quebec's special QST rules.
Simply select your client from your saved contacts, and Cadig instantly applies the correct tax rate based on their province. The app handles complex scenarios like Quebec's dual GST/QST system automatically.
For a $1,000 invoice to an Ontario client, Cadig automatically applies 13% HST ($130), totalling $1,130. For Quebec? It calculates 5% GST ($50) and 9.975% QST ($99.75) on the subtotal—exactly as CRA requires.
