The basics
- your business name, address, phone and license number
- the customer’s name, and the job address if it is different
- an invoice number, the date and a due date
- the contract or estimate it bills against, and which payment this is
- labor, materials and equipment rental on separate lines
- any retainage held back, on its own line
- sales tax only where your state taxes it, then the total due
Progress billing that gets paid
On a staged job, show where the work stands on every invoice: the schedule of values line, the percent complete this period, what was billed before, this invoice and the balance to finish.
If the customer holds back retainage, show it as its own line with the condition for its release, so claiming it at the end is simple. Bill each change order on its own line with its reference number.
Sales tax on labor and materials
There is no federal rule, and states treat labor and materials differently. Two examples:
- Texas: labor to repair, remodel or restore residential property is not taxable, but the whole charge for remodeling, repairing or restoring nonresidential property is.
- Texas contracts: on a lump-sum contract (one price for the whole job) you pay tax on materials when you buy them and charge the customer none. On a separated contract you bill materials and labor separately, buy materials on a resale certificate and collect tax on the materials.
- California: contractors are generally the consumers of the materials they use, so they pay the tax when they buy them, but they are the retailers of fixtures they supply and install. On time-and-material jobs, list materials and fixtures separately from installation.
Elsewhere, check your state’s rules, enter your rate, and untick any line that is not taxable.

License numbers and Florida notices
California and Florida want your license number on bids, proposals and contracts, and Arizona on written bids and estimates, preceded by “ROC”.
In Florida, a residential contract over $2,500 also needs the Homeowners' Construction Recovery Fund notice, and any direct contract over $2,500 needs the Construction Lien Law disclosure in capitalized bold type of at least 12 points, signed and dated by the owner. Those notices go in the contract; the invoice names the contract it bills.

Subcontractors billing a general contractor
A general contractor that pays you $2,000 or more in a year, for payments made after December 31, 2025, files a Form 1099-NEC and will ask for your Form W-9 first. Payments to corporations are generally not reported. Send the W-9 with your first invoice so payment is not held up.

Construction invoices in the UK
Billing a contractor for construction work? The Construction Industry Scheme probably applies. The contractor deducts 20% if you are registered for CIS and they can verify you, 30% if not, and nothing if you have gross payment status. No deduction is taken from VAT, materials you paid for, plant hired for the job or consumable stores, so put those on their own lines. Use the CIS invoice template, or check the sums with the CIS calculator.
If you and the contractor are both VAT registered and the work is reported under CIS, the domestic reverse charge usually applies: VAT is shown on the invoice but not charged. It does not apply to work for a homeowner, or for a customer who tells you in writing that they are an end user. For householders, use a normal UK invoice.
