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.
Should my hourly rate include VAT?
For business clients, rates are usually quoted excluding VAT, with the VAT added on the tax invoice. Prices to consumers must include VAT.
What if I’m not a VAT vendor?
Choose “No VAT”: your invoice is titled “Invoice” and shows no VAT at all.
