Who it's for
Builders, tradespeople, and construction contractors who need to separate labor, materials, and fees on a single clear invoice, and who often work from a deposit followed by a final balance.
Frequently asked questions
What should a contractor invoice include?
A contractor invoice should separate labor (hours × rate) from materials and any permit, equipment, or disposal fees, so the client sees exactly what they're paying for. Include the job address, a description of work, your license number if required, and payment terms. This tool pre-splits those lines for you.
Should contractors ask for a deposit?
Yes. For larger jobs, a 30–50% deposit on acceptance protects you against material costs and no-shows. The default terms here include a 50% deposit line you can edit.
How do I bill for materials vs labor?
Keep them on separate lines. Labor is usually hours times your rate; materials are billed at cost (or cost plus a markup you disclose). Separating them builds trust and makes disputes rare.
Do I need to show my license number on a contractor invoice?
In many regions, yes. Licensed trades are frequently required to display a license or registration number on invoices and quotes, and an invoice missing a legally required field can be rejected by a client or cause problems in a dispute. Requirements vary considerably by country and by trade, so confirm the rule where you operate once rather than guessing. Even where it is not mandatory, showing your license number is worth doing. It signals to a homeowner comparing quotes that you are properly registered, which is often the difference between winning the job and losing it to a cheaper unlicensed bid.
How should I handle change orders?
Confirm every change in writing before you carry it out, stating the additional cost and the revised total. Most contractor payment disputes are not about the original quote, they are about work added along the way that was agreed verbally on site and then questioned when the final bill arrived. A brief message is sufficient: confirm the extra work, the added cost, the new total, and ask the client to reply confirming. Keep the reply. On larger additions, take a further deposit for materials. This single habit prevents the overwhelming majority of end-of-job disagreements in the trades.
Should I bill materials at cost or with a markup?
Both are normal, but disclose which you are doing. Billing at cost plus a stated markup is standard and covers sourcing, collection, and the cash you fronted. Problems arise only when a client discovers an undisclosed margin they were not expecting. Keep materials on a separate line from labor either way, since customers accept a large total far more readily when they can see that most of it was materials rather than your time. Separating the two also makes warranty conversations easier, because parts and workmanship are usually guaranteed for different periods.
When should I invoice on a long job?
Stage it. On anything running more than a couple of weeks, a single deposit and a final bill leaves too much money sitting at the end, exposed to whatever goes wrong. Tie payments to observable milestones, for example a deposit on acceptance, a payment when the main installation is complete, and the balance on sign-off. Milestones tied to visible progress cause far fewer arguments than milestones tied to dates, because nobody has to agree on the cause of a delay in order to agree that the work in question is finished.
