What a construction invoice has to show
A construction invoice is a running account of a contract, not a receipt for a day's work. It should name the contract or job it belongs to and the phase being billed, show the deposit already collected and where it was applied, and carry the allowances with enough detail for the owner to see what was budgeted and what has so far been spent against each one.
Permits belong on the invoice as well, shown as a pass-through line, with the number on it and the owner's name on the paperwork when that is how it was pulled. Keep a running contract total visible at the bottom of every invoice, even as a small summary line. An owner comparing the third invoice against the signed bid is really asking one question: does the bid still hold?
Bid it fixed, bill it by phase
Residential construction runs most smoothly on a fixed-scope bid with a deposit at signing followed by invoices as phases complete: site prep, foundation, framing, rough-ins, finishes, close-out. Each phase invoice should land when the phase is genuinely finished, not when materials arrived at the property. An owner who has walked their own finished frame is a far easier collection conversation than an owner staring at a garage stacked with lumber.
Deposit sizing is a local question: ten percent is the common opening at signing, several states cap what a residential builder may collect before work begins, and an honest opening number buys the long-lead orders (trusses, windows, the excavator week) without financing a job that has not started. Check your state's cap before asking for a third up front, and let the contract's milestone schedule remain the source of truth for every amount rather than re-deriving figures by feel.
Materials markup and allowances, in the open
Materials markup is how a builder eats between bids, and the invoice is where it usually goes wrong, not because the markup was hidden but because it appeared without explanation. If the contract says cost plus 15% on supplied materials, the invoice line should say the same words: lumber package, cost plus 15%. The supplier receipts stay in the job file; the invoice states the treatment, not a mystery number.
Allowances run the same mechanism in the other direction: a tile allowance is a placeholder line in the bid, and whichever way the owner's selection lands (over or under the allowance) it is reconciled on the next invoice. State the reconciliation method once on the contract and repeat it on the invoice line whenever a selection lands outside its number. An owner who learns of an overrun from a line item has nothing to be defensive about; an owner who learns from a phone call reads the next invoice twice as skeptically.
Lien waivers from first payment to close-out
A lien waiver is the document that says you were paid for work you will not file against. The normal rhythm runs like this: send a conditional waiver with each invoice, which becomes effective once the payment clears, and hold the final unconditional waiver until the close-out payment, the permit sign-offs and the punch walk are actually finished. Owners and, more often, their lenders will ask for the waivers by name.
Keep every waiver in the job file beside the permit card and the supplier receipts. A builder who can hand a closing attorney one folder (contract, a waiver per payment, closed permits, the final invoice) gets referred to the next job. A folder missing the waiver for milestone three gets a week of phone calls that produce nothing but paperwork archaeology.
Taxes on construction invoices
Construction sales tax is the most state-specific of any trade here. Some states tax materials only, some tax lump-sum residential contracts in their entirety, and several treat new construction differently from remodeling. How your contract is written (lump sum versus time and materials) can also change what is taxable. Keep materials and labor separated on every invoice, and ask your state's department of revenue or an accountant which treatment applies before you bid.
