Frequently asked questions
Is tax charged on the discounted amount?
Yes. Discount first, then apply tax to the net figure — that's standard practice and what tax authorities expect.
What payment terms should I use?
Net 14 or Net 30 are common. Shorter terms with a late fee clause noticeably improve payment times for freelancers.
