Contractor invoicing: how to bill labor and materials correctly
Contractors, handymen, plumbers, electricians and remodelers face invoicing challenges that office-based businesses don't: mixed labor and materials, deposits collected before work starts, change orders and clients who want to understand every line. A clear contractor invoice prevents disputes and protects your right to be paid — in many regions, your paperwork matters if you ever need to file a lien.
Separate labor from materials. List labor by task with the hours worked and your hourly rate, and list materials either individually or grouped by category with their cost. Some jurisdictions tax materials and labor differently, so keeping them on separate lines makes it easy to apply per-line tax percentages where needed.
Record deposits in the Amount Paid field. If you collected a deposit before starting, the invoice will show the full job total, the deposit already received and the remaining balance due — exactly what homeowners and general contractors expect to see. For change orders, add them as distinct line items with a clear description and date.
Include your license number and insurance details in the business section or notes if your trade requires it, along with job site address and a short description of the work completed. State your payment terms clearly — Net 15 is common in the trades — and any late fee policy permitted in your area.
Because the tool runs in your browser and remembers your business details, you can create and send an invoice from your phone before you leave the job site. Getting the invoice in front of the client while the work is fresh is one of the most effective ways to get paid faster.
