How to Write an Invoice for a Deposit and Remaining Balance
For staged billing, issue two documents: a deposit invoice for the agreed upfront amount, then a final invoice that shows the full job price, subtracts the deposit already paid as its own visible line, and totals only the balance. The customer can follow the whole job across the two pages, and nothing is ever charged twice.
The deposit invoice
Keep it unmistakably a deposit. Title the single line with the job and the stage: “Deposit — kitchen remodel, 418 Alder St (40% of agreed price $4,800)” with an amount of $1,920. The notes carry the agreement in one sentence: “Deposit toward the agreed fixed price of $4,800 for the kitchen remodel at 418 Alder St. Balance of $2,880 invoiced on completion.” Give it its own invoice number — it is a real invoice, and your records treat it as one (numbering rules).
The final invoice
- Line 1: the full job at the full agreed price — “Kitchen remodel, 418 Alder St — agreed fixed price” $4,800.
- Line 2: the deposit as a negative line — “Less deposit already paid (invoice 1031)” with quantity 1 and rate −$1,920, so the maker shows −$1,920.
- Total due is the balance: $2,880. If tax applies to the job, apply it the way your jurisdiction expects for staged payments — commonly on the full price across the stages, not invented fresh at the end; when unsure, your accountant's answer for your situation outranks this paragraph.
The mistakes this pattern prevents
- Billing the balance as if it were the whole job (“Remodel — $2,880” with no reference to the price): the customer cannot reconcile it against the agreement and asks questions.
- Putting the deposit in the notes only: notes get skimmed; a customer who pays the full $4,800 twice has a legitimate complaint and you have a refund to process.
- Editing the deposit invoice into the final one: two stages, two documents, two numbers. An edited file erases the trail your records exist to keep (how that archive works).
Stage one or stage two, the mechanics are the same: open the maker, describe the stage on the line itself, and download. For hourly work billed in stages, the same structure applies — see how to invoice for hourly consulting work.
Progress amounts on longer engagements
For work spanning weeks, replace the single deposit with stage amounts: a deposit to begin, a progress amount at a named milestone, and the balance at delivery. Each stage gets its own invoice describing what that stage completed, and the final document recaps the chain — deposit amount and date, progress amount and date, balance now due — so the client's complete set of paperwork sums to the engagement without any document needing to tell the whole story alone. Two disciplines make staging work: milestones defined by *deliverables* (“homepage design approved”, “foundations complete”), never by calendar dates alone, because dates slip and deliverables either exist or do not; and each stage invoice created when the milestone lands, not batched at the end — a stage billed late teaches the client that stages are negotiable.
If a project pauses mid-way, the stage structure is also your protection: completed stages are documented and billable as they stand, and the remaining stages were never invoiced, so there is nothing to unwind — only a clean place to resume from.
