Free Quantity Surveyor Invoice Template & Generator

Your invoice needs the specific project address and any reference numbers from the initial appointment or contract. Include which RIBA stage or work phase you're billing for because clients track costs against their development budgets this way. Break down your fee by the actual service provided, whether that's cost planning, measurement, tender analysis, or contract administration. If you've incurred expenses like site visits or specialist software costs for the project, show these separately. Clients will query lumped figures every time.

Most quantity surveyors work on stage payments tied to project milestones. You might invoice a third upfront, a third at tender stage, and the final third at project completion. Some prefer monthly billing on larger jobs. Standard payment terms are 30 days, though main contractors often push for 60. Get the payment schedule written into your appointment document before you start.

Send your invoice the day you complete each stage, not weeks later when you get around to admin. Late invoices get pushed to the next payment run. Also, never bill for work on a project that hasn't had a written appointment letter signed by both parties. Handshake agreements fall apart when payment is due.
