How to write a contractor invoice
- Quote the client's purchase order or contract number; many companies will not pay an invoice without it.
- Attach or reference the approved timesheet for the period you are billing.
- List expenses on their own lines and keep the receipts.
- Check whether your client must withhold tax from your payments in your country.

How do contractors invoice for a day rate?

Can I add expenses to a contractor invoice?
Yes, if your contract allows it. Put each expense on its own line, keep the receipts and do not add a markup unless it was agreed.
