Separate Labor & Materials
Clearly divide physical supply costs from hourly or flat-rate skilled labor to maintain client transparency and prevent markup disputes.
Milestone Progress Billing
Invoice for completed project phases (e.g. 30% Foundation, 40% Rough-In, 30% Final Walkthrough) with sequential invoice numbering.
100% Private Client Storage
Your job site addresses, subcontractor rates, and client contact information never leave your local device. Zero cloud databases.
What Every Independent Contractor Invoice Must Include
Whether you work in construction, electrical, carpentry, HVAC, or general subcontracting, your invoice is a legal record of finished work. Leaving off key details can delay client checks for weeks.
1. Job Site Location & Project Reference
Always specify the exact physical job site address and project name (e.g., "Job Site: 742 Evergreen Terrace — Kitchen Remodel Phase 2") so the property owner or general contractor can cross-reference with their site superintendent’s logs.
2. Contractor License & Insurance Numbers
Commercial clients and general contractors require license numbers for compliance before cutting checks. Add your state license or trade certification number directly under your business header notes.
3. Itemized Supply & Material Receipts
List major materials (e.g., drywall sheets, copper piping, lumber) on separate lines from your labor charges. If you charge a standard contractor markup (typically 10–20%), clarify whether prices are inclusive of supplies.
4. Retainage & Holdback Terms
In large commercial contracting, clients often withhold a 5% to 10% retainage fee until final project inspection. Clearly state the subtotal, the retainage withheld, and the net balance currently payable.
