Deposit Invoice: How to Request an Upfront Payment

September 18, 2026

A deposit invoice requests an agreed upfront payment before a project starts or before a later booking or delivery step. It should clearly distinguish the total project price from the smaller amount the client is being asked to pay now.

The correct billing document and tax treatment depend on your location and the transaction. For example, the UK has specific VAT guidance for deposits and instalments; those rules are not a worldwide standard. This guide explains the communication and payment-tracking workflow; the examples are not tax-invoice templates for a specific country.

Agree the deposit before issuing the request

Put the deposit amount or percentage in the quotation or agreement. Explain when it is due, what it is applied against, and what happens next. If work starts only after payment is confirmed, say that before the customer accepts.

Refund, cancellation, and rescheduling terms should also be agreed in advance and comply with applicable rules. Calling a payment a “non-refundable deposit” on an invoice does not resolve every contractual or consumer-law issue.

Calculate the upfront amount

Suppose a design project costs $2,000 before tax and the parties agree a 30% deposit. The calculation is:

Deposit requested = $2,000 × 30% = $600.
Unbilled project value after that stage = $2,000 − $600 = $1,400.

The $1,400 is not automatically overdue or payable immediately. Its billing event and due date come from the agreed project schedule. Also distinguish “requested” from “received”: an unpaid $600 request does not prove that the client has paid a deposit.

Deposit request example

FieldExample wording
Document referenceDEP-2026-014
Project referenceBrand identity project / Quote Q-014
Description30% upfront payment against agreed project fee
Project price before tax$2,000
Amount requested now before tax$600
Request date / payment due1 October 2026 / 8 October 2026
Next billing eventRemaining project fee on agreed final approval

Add the parties' details, currency, appropriate tax and registration information, and payment instructions. Use the document type required by your billing and tax process, which may distinguish a payment request or proforma from an issued tax invoice.

Record the payment only after confirmation

When the deposit arrives, record the date, amount, currency, payment reference, and the document it settles. A transfer screenshot or customer email may help identify a payment, but check your receiving account or payment provider before marking it received.

Keep the customer-facing confirmation simple: “We have received $600 against DEP-2026-014 for project Q-014. The next billing stage is final approval, as agreed.” Keep the payment record separate from the decision about when income is recognized in your accounts.

Avoid charging the deposit twice

Use one consistent method supported by your billing system. If separate stage invoices bill $600 and then $1,400, the invoiced project total is $2,000. The second invoice should identify the remaining stage; it should not add the $600 deposit again.

Some systems instead use a full project invoice with an earlier advance payment applied against it. In that workflow, the $600 reduces the balance due on the $2,000 invoice. Ensure any earlier billing document is handled correctly so you do not leave both a full invoice and a duplicate deposit charge outstanding.

A payment is not a discount. A $600 deposit reduces what remains payable; it does not reduce a $2,000 agreed selling price to $1,400. Have the applicable tax treatment confirmed before issuing the documents.

Deposit request email wording

Hi Alex, attached is the agreed 30% deposit request for project Q-014. The amount requested is $600 before any applicable tax, due on 8 October. We will confirm the start schedule once payment is received. The remaining project fee will be billed at final approval under the agreed terms.

Frequently asked questions

Is 30% the standard deposit?

No. It is only the example used here. Choose and agree an amount appropriate to the project, costs, and customer relationship.

Is a deposit invoice proof of payment?

No. It requests payment. Keep a receipt or payment confirmation after the money has been received.

Can I just subtract the deposit as a discount?

No. Keep the original price and the payment allocation distinguishable. Otherwise, you can understate the sale or confuse the remaining balance.
