What to check for this job

A freelance project combines tracked work, a fixed-fee deliverable and an agreed expense. Reference the contract or PO so the client's finance team can approve the invoice without asking what the work was for.

See the freelancers workflow in Experi →
  • Project and client PO reference
  • Billing period or milestone
  • Hours versus fixed-fee deliverables
  • Agreed expenses and payment terms

Watch out: Do not present illustrative rates as a recommended freelance rate or charge a fixed milestone and its included hours twice.

Frequently Asked Questions

How should I invoice as a freelancer?

Include a unique invoice number, issue and due dates, your details, the client's details, a precise description of the work, the price, any applicable tax, the total due and payment instructions. Add the project or purchase-order reference when the client supplied one.

Do I need to charge VAT as a freelancer?

Only add VAT when your business is VAT-registered. Show your VAT number and use the correct VAT treatment for the supply; not every supply necessarily uses the standard rate, so check your circumstances or ask an adviser.

Should a freelancer invoice by hour or by milestone?

Match the invoice to the commercial agreement. For hourly work, show the period, hours and rate. For a fixed-fee project, name the accepted milestone and the agreed amount. Do not mix models without explaining the line items.

Can I add expenses to a freelance invoice?

Yes, when the client agreed to reimburse them. Itemise each expense, keep the receipt and make the tax treatment clear rather than hiding it inside a vague project fee.
