How IT contractors usually bill
Usually a day rate against approved timesheets, sometimes a fixed-price deliverable. Invoice to the agency or the end client, whoever holds your contract.

- Your client's name and address, and their PO or project reference
- A unique invoice number, for example INV-OCT-001
- Issue date, due date and payment terms
- A clear description, quantity and price for each line
- Tax, only if you are registered, with the rate and amount
- How to pay: a card payment link and your bank details
Tips to get paid faster
