Free Contractor Invoice Template

A solid contractor invoice covers both the money and the paperwork a client — and later the tax office — may need: your business name and contact details, your contractor license number where required, the client and the job/site address, an itemized breakdown of labor and materials, applicable tax, the total, and clear payment terms.

Itemizing matters. Clients are far more likely to pay promptly when they can see exactly what each charge is for, rather than a single 'services rendered' figure.

Always list labor (hours × rate) separately from materials and equipment. There are two good reasons. First, transparency: clients want to see what they're paying skilled hands for versus what went into supplies. Second, tax: in many US states labor isn't taxable but materials are, so combining them makes correct tax impossible.

If you mark up materials — most contractors do, to cover sourcing and handling — bill the marked-up price as your line item rather than showing your cost. Your margin on materials is a normal, expected part of the job.

On anything bigger than a small job, don't wait until the end to invoice. Bill in progress payments tied to milestones — for example a deposit to start, a payment when the work is halfway or 'dried in', and the balance on completion. This protects your cash flow and limits your exposure if a client stops paying.

When the scope changes, raise a change order and add it as its own clearly-labeled line item that references the original estimate or contract number. Never absorb extra work silently — a documented change order is how you get paid for it and how you avoid disputes.

Ask for a deposit before you start, set short payment terms (Net 15 is common in the trades), and state the payment methods you accept on the invoice. Add a late-fee clause and, where your jurisdiction allows, note your lien rights — both encourage prompt payment.

Include your license number and, if you offer one, your workmanship warranty. These small details make the invoice look professional and reassure the client they're dealing with a legitimate, insured tradesperson.
