How do I show a deposit on a final invoice?

List all line items at full value, show the complete job total including tax, then add a clearly labelled line such as "Less deposit paid: –$X," and show the remaining balance due. This proves you are charging exactly what was agreed and prevents the client from thinking they are being billed twice.

Is a deposit invoice the same as a final invoice?

No. A deposit invoice bills an upfront portion before work begins to fund materials and secure commitment. A final invoice is sent after the job is complete, showing the full total with the deposit deducted so only the remaining balance is due. Together they bill one job in two parts.

Do you charge tax on a deposit invoice?

Generally you apply tax to the full job total and make sure the deposit and final invoice reconcile to that total, rather than taxing the two parts in ways that do not add up. Keep the math clean so the final invoice totals match the original quote. Confirm the correct treatment for your jurisdiction with your accountant.

Deposit Invoice vs Final Invoice

What each invoice does

On any job large enough to bill in two parts, you're really sending two invoices that work together.

A deposit invoice goes out before the work starts. It bills the client for an agreed upfront portion — often 25–50% — that funds your initial materials and secures their commitment to the job. It's a request for the first slice of the total, not an extra charge on top of it.

A final invoice goes out when the work is complete. It shows the full value of the job, then subtracts the deposit the client already paid, leaving only the balance due. The final invoice is where the two parts reconcile into one clear, total picture of the job.

How to show the deposit on the final invoice

This is the part contractors get wrong, and it's the part that confuses or annoys clients. The final invoice must make the math obvious. The clean structure is:

List all the line items at full value.
Show the job total (with tax).
Add a clearly labelled line: "Less deposit paid: –$X".
Show the balance due — the only number the client now needs to pay.

Never just send a final invoice for the remaining balance with no reference to the deposit. The client sees a number, can't reconcile it against the quote they agreed to, and you get a "wait, why is this amount different?" email. Showing the full total and the deduction proves you're charging exactly what was agreed — no more.

The mistakes that cause disputes

Three errors cause almost all deposit-related disputes:

Double-charging by accident. Billing the full total on the final invoice and forgetting to deduct the deposit — the client pays the deposit twice in effect, notices, and trust takes a hit. Always deduct.

Unclear records. If you can't quickly show what the total was, what the deposit covered, and what's outstanding, a client who queries the bill has nothing to anchor to. Keep the quote, deposit invoice, and final invoice linked to the same job.

No tax clarity. Apply tax to the full job total, then deduct the deposit from the tax-inclusive total — don't tax the deposit and the balance in ways that don't add up. Keep the final invoice's totals reconciling cleanly to the original quote.

Keeping both invoices tied to one job

The whole system depends on the deposit and final invoices being two views of a single job, not two unrelated bills. When they're linked, the final invoice can automatically carry the full total and deduct what's already been paid — and you always know exactly what's outstanding on the job.

Fieldpaid handles this by keeping the quote, deposit, and final invoice connected to the same job, so the deposit is deducted correctly on the final bill, the balance due is calculated for you, and the payment link and automatic reminders apply to whatever is still owed. No manual subtraction, no double-charging, no confused client.
