What to include on a construction invoice
On top of your company details, the owner's details, an invoice number and dates, a construction invoice needs to tie the payment to the contract and the job.
- Project, job address and contract
- Name the project, the job site address and the contract or job number as custom fields in the invoice header. On a job with several invoices, this is how everyone finds the right one.
- Which progress payment this is
- Say where the invoice sits in the schedule, for example “Progress bill 2 of 4” or “Billing period: October”, so the owner or lender can match it to the payment schedule in the contract.
- Work by phase or percent complete
- Bill each phase from your schedule of values. Put the share completed this period in the quantity column (0.6 for 60%) and the phase value as the rate, and the amount works itself out.
- Change orders, separately
- Approved change orders get their own lines with the change order number, never folded into the original phases. Owners check them against the signed change orders, not against the base contract.
- Permits, materials and equipment
- Permit fees, dumpsters, equipment rental and materials billed outside the phases go on their own lines. Stored materials that the contract lets you bill before installation should be described as stored.
- Retainage and lien waivers
- Show the retainage withheld as its own line so the net amount due is clear. If your contract or lender requires a lien waiver with each payment, mention it in the notes and attach it; the forms and rules differ by state.
