Frequently asked questions
How do I bill 45 minutes?
Enter 0.75 hours. Minutes ÷ 60 gives the decimal: 30 minutes is 0.5, 20 minutes is 0.333.
Do I charge GST on consulting?
Yes, once you’re registered for GST/HST — most services are taxable. PST usually doesn’t apply to consulting, but check the province’s rules.
What if I’m a small supplier?
Choose “None”: until you register, your invoices show no GST/HST at all.
