How to invoice as a contractor
Construction and trade invoices separate labour from materials, and large jobs are billed in progress draws rather than one lump sum. An invoice that shows the schedule of values — what each stage cost and what is left — keeps a project paid on time.
This template opens with labour, materials and a progress line. Add the job address and any change orders, apply tax where it applies, and export a PDF a general contractor or homeowner can sign off without a phone call.
What to include
- Job site address and project reference
- Labour — hours or a fixed stage fee
- Materials, itemised or as a lump sum
- Progress draw / percentage of contract complete
- Approved change orders, listed separately
Typical terms: Due on receipt · progress billing per schedule of values
Frequently asked questions
How do I invoice for a progress payment?
Bill the percentage of the contract completed for the period as its own line — for example "30% of contract — foundation complete." Listing draws against a schedule of values keeps long jobs cash-flow positive and easy for the client to verify.
Should labour and materials be separate?
Yes. Clients, general contractors and insurers expect labour and materials on separate lines (and tax often applies differently to each). This template lets you itemise both clearly.
How do I handle change orders on an invoice?
Add each approved change order as its own line item referencing its number, so the extra scope is documented and separate from the original contract amount.
