Free Contractor Invoice Template — Excel & Google Sheets
Send contractor invoices with labor, materials, project references, progress billing, and total due in one spreadsheet. Free Excel and Sheets template.
What should a contractor invoice include?
Contractor invoices usually need more job context than a generic invoice. Clients often need a job name, site address, work period, purchase order or project reference, and a clear split between labor, materials, and other billable items. In many cases the invoice also needs to support staged or progress billing rather than a single final payment. This template is built for those realities so the billing record is understandable to the client, their operations team, and their accounting team at the same time.
What is included in this template
The layout includes contractor and client details, invoice number, issue and due dates, job reference fields, and an itemized table you can use for labor hours, materials, equipment, or change-order work. Totals are calculated automatically, and the notes section gives you a place to record milestone billing terms, retainage context, site instructions, or payment requirements. That makes it practical for both one-off jobs and longer engagements with multiple billing events.
Who should use this contractor invoice template?
It works well for general contractors, subcontractors, tradespeople, renovation crews, field-service operators, and service businesses that need a spreadsheet invoice with more project detail than a basic consulting invoice. It is especially useful if your clients want billing tied to a specific site, work order, or progress milestone rather than a generic monthly invoice.
How to use it
Replace the sample business and client details, then add the job name, work period, and any PO or reference number the client expects. Enter labor, materials, and other billable line items separately so the invoice reads cleanly. If the job uses progress billing, make the milestone clear in the notes and double-check that any retainage or prior billing is reflected before you send it. Griddy can then help you add new phases, recalculate tax, or turn field notes into a cleaner invoice narrative.
