A construction or trades invoice has to hold up to more scrutiny than most — clients want to see exactly what they paid for labor versus materials, and any work added after the original quote needs to be clearly separated from what was agreed at the start. Materials often carry a markup and should be backed by receipts you can produce if asked; labor is usually billed by the day or hour and should reflect the crew and time actually on site; and site preparation, permits, or disposal fees deserve their own line rather than getting folded into "labor." Change orders — extra work requested mid-project, like additional electrical runs that weren't in the original scope — are one of the most common sources of payment disputes in this industry, and the fix is simple: list them as their own clearly labeled line item, ideally referencing the change order number from your paperwork. The template below is pre-filled with a typical job: labor days, materials, site prep, and a change order for extra electrical work. Adjust it to match your own job and export a PDF ready for the client's records.

How should I bill for materials versus labor?
Keep them as separate line items. Materials are often marked up and should be backed by receipts you can produce if asked; labor is usually billed by the day or hour and should reflect the crew and time actually on site. Mixing the two into one number makes both harder to justify.
What's a change order and how do I invoice for one?
A change order is work added after the original scope was agreed — for example, extra electrical work discovered mid-project. List it as its own clearly labeled line item, ideally referencing the change order number from your paperwork, rather than folding it into the original quoted price.
Should I ask for payment upfront on a construction job?
A deposit before work begins is standard practice, especially for jobs requiring you to purchase materials in advance. Larger jobs typically add progress payments tied to milestones, with a final payment due on completion — spreading the risk instead of carrying the whole project cost yourself.
