Deposit Invoice: How to Bill 50% Upfront Without Losing the Job

A deposit invoice — also called a down payment invoice — is an invoice you send before starting the work, for a portion of the total project fee. Common amounts are 25%, 33%, or 50%. The balance gets invoiced when the project is delivered, with the deposit applied as a credit on the final invoice.

The purpose is simple: you don't want to start a 6-week project, deliver it, and then discover the client never had any intention of paying. The deposit filters out clients who can't or won't pay, smooths your cash flow, and aligns commitment on both sides. For freelancers without recurring retainer revenue, deposit invoices are the single biggest tool for not getting burned.

This guide covers the right percentages, when to ask, exactly what to put on the invoice, and the contract language that makes the deposit non-refundable in the cases where you need it to be.

When to require a deposit

Three triggers, in increasing order of strictness:

1. First-time clients (always). No payment history with you = require a deposit. This is non-negotiable for new clients above ~$500 of work.
2. Projects above a threshold (e.g., $2,000). Even for repeat clients, larger projects justify a deposit because the cash-flow risk to you scales with the project size.
3. Long-duration projects (>2 weeks). Anything that ties up your calendar should have a deposit. The opportunity cost of saying no to other work is real, and a deposit prices that in.

Categories where you should not skip the deposit, regardless of client size:

• Custom work with no resale value (one-off branding, custom code) — if the client backs out, you can't sell the work elsewhere
• Work that requires upfront expenses on your side (printing, third-party software, subcontractors)
• Tight deadlines (rush work) — the deposit prices in the disruption to your schedule

What percentage to ask for

The defaults that hold across most industries:

| Project type | Typical deposit | Why | |---|---|---| | Small project (under ~$2k) | 50% | Simple split; covers risk for both sides | | Mid-size project ($2k–$10k) | 33% (1/3) | Lower friction; balance still meaningful | | Large project ($10k+) | 25% or milestone-based | Lump-sum 50% is a hard sell; consider milestone billing instead | | Rush work | 50% minimum, often 100% | Disruption to your schedule justifies higher | | Subcontractor or third-party expenses included | Deposit covers expenses + first work period | You can't be net-negative on this client |

The 50% default is the safest for new clients on small projects because it's psychologically easier than asking for 100% upfront and still gives you meaningful protection.

For larger projects, asking for 50% upfront often loses the deal. The 33% (or one-third) deposit is a much easier sell — clients perceive it as reasonable, but it still covers most of your risk if the project gets canceled early.

For projects above $10k, consider milestone billing instead of a single deposit. Three or four mid-sized invoices throughout the project are easier on the client's AP team than one large deposit.

When to invoice the deposit

The deposit invoice should be issued after the contract is signed but before you do any billable work. Specifically:

1. Send the contract or SOW for signature.
2. Once signed, send the deposit invoice with payment terms of Net 7 or Net 14 (not Net 30 — the deposit is supposed to be paid quickly).
3. Begin work only once payment clears. "Clears" means money in your account, not "I received notice of payment."

If you skip step 3 and start work on signature alone, you've gained nothing from requiring a deposit. The most common way deposit invoices fail is the freelancer starting early to be helpful and then having to chase a late deposit while burning hours.

What to put on a deposit invoice

A deposit invoice has the same structure as a regular invoice (see how to write an invoice) with three additions:

1. Clear "deposit" framing in the line item

The line item should explicitly say it's a deposit and reference the total project:

Deposit (50%) — Website redesign project              $5,000.00
  50% of total project fee ($10,000), per SOW dated May 1, 2026.
  Balance of $5,000 due on project completion.

This prevents two confusions: (1) the client thinking the invoice is the entire fee, (2) the client thinking the deposit is a separate one-time fee that doesn't apply to the total.

2. Statement of what the deposit secures

Below the line item or in the description, state what the client is paying for:

This deposit secures the project start date of May 15, 2026 and reserves
[Your Name] for the agreed scope. Work begins upon receipt of payment.

This converts "you owe me $5,000" into "your $5,000 buys you a specific outcome and timing." Easier for the client's AP team to approve and harder for them to renegotiate later.

3. Refundability statement (carefully)

Whether the deposit is refundable matters more than people realize, and the answer should be in the contract — but it should also appear on the invoice for clarity:

Deposit is non-refundable once work has begun. If the project is canceled
by the client before work begins, the deposit is refunded less a $250
administrative fee.

If you make the deposit fully non-refundable from the moment of payment, a client who pays then cancels the same day will feel scammed and may dispute the charge through their bank. The "non-refundable once work begins" framing is more defensible.

Sample deposit invoice

Deposit non-refundable once work has begun.
ACH: routing 000000000 / account 0000000000

How to apply the deposit on the final invoice

The final (balance) invoice should reference the original deposit explicitly:

Description                                              Amount
----------------------------------------------------------------
Website redesign project — full fee                  $10,000.00
  Per SOW dated May 1, 2026.

Less: deposit paid (Invoice #2026-0501, May 1)        ($5,000.00)

                                       Balance due:    $5,000.00

Two things matter here:

1. The full project fee appears on the final invoice. Not just the balance.
2. The deposit is shown as a credit, with a reference to the deposit invoice number and date.

This ordering makes the final invoice look like a complete record of the engagement — what was agreed, what was already paid, what's still owed. The client's AP team can match it against their records without you having to send a separate explanation.

If the client wants the deposit invoice to be the only invoice (and the balance invoice to only show the balance), that's also fine — but the balance invoice should still reference the deposit invoice number so the audit trail holds.

Deposit vs retainer vs proforma — they're all different

Three documents people confuse:

• Deposit invoice — one-time partial payment for one specific project. Applied as credit on the final invoice. Covered in this guide.
• Retainer invoice — recurring monthly fee for ongoing availability or hours. Not project-specific; doesn't get "applied" to anything.
• Proforma invoice — preliminary invoice for quoting purposes. Looks like an invoice but is not a request for payment.

The key difference is the relationship to the underlying work:

• A deposit is partial payment for a specific deliverable.
• A retainer is payment for time and availability, no specific deliverable.
• A proforma is a quote in invoice form, not a payment request at all.

Common mistakes to avoid

1. Starting work before the deposit clears. As above — this is the most common failure mode. Don't open the design file until the bank confirms.

2. Not having a written contract or SOW. A deposit invoice without a contract is half a transaction. The contract defines what the deposit secures, the refund policy, the scope, and the deadline. The invoice references the contract.

3. Making the deposit too small to actually matter. A 10% deposit on a $20,000 project is $2,000 — not enough to cover the lost opportunity if the client cancels in week 2. 25–50% is the floor for actual protection.

4. Treating the deposit as separate from project totals. The client should always see the total project fee on both invoices, with the deposit shown as a credit. Splitting it into two unrelated invoices ($5,000 deposit, then $10,000 final) creates billing confusion and the appearance of being overcharged.

5. Forgetting to apply the deposit on the final invoice. Easy to do if you have multiple projects active. Always cross-reference the deposit invoice number on the final invoice.

FAQ

How much deposit should I ask for as a freelancer?

50% for first-time clients on projects under $2k. 33% for projects between $2k and $10k. 25% or milestone billing for projects above $10k. These are the defaults; adjust higher for rush work, lower for trusted repeat clients on small projects.

Is a deposit invoice the same as a proforma invoice?

No. A deposit invoice is a real invoice — it's a request for payment that creates an account receivable. A proforma invoice is a preliminary document that looks like an invoice but doesn't request payment; it's used for quotes or customs declarations.

Should a deposit be refundable?

Usually: refundable up until you start work, non-refundable after. Fully non-refundable from moment of payment invites dispute. Fully refundable until project completion defeats the point. The middle is most defensible.

Do I need to charge sales tax on a deposit?

Depends on your state and what the deposit covers. In most US states, sales tax on services follows the work, not the payment timing — so the tax is recognized when the work is delivered, not when the deposit is paid. Consult your CPA; the rules vary.

What if the client refuses to pay a deposit?

Three options, in order: (1) hold firm and decline the project — clients who refuse deposits are the ones who don't pay final invoices either; (2) reduce the deposit ask (50% → 33%) if the client is otherwise solid; (3) require a smaller deposit and milestone billing thereafter. Walking away is often the right call.

How is a deposit different from earnest money or a retainer fee?

"Deposit" in the freelance context = partial payment toward a specific project. "Earnest money" is a real-estate term — money showing good faith in a property purchase. "Retainer fee" usually means ongoing monthly payment for availability (see retainer invoice). These have different legal and accounting treatment; don't use them interchangeably.

Can I require a deposit and charge interest on the balance?

Yes. A deposit and late fees on the balance are independent mechanisms. The deposit covers the cash-flow risk of the first phase; late fees cover the risk that the balance gets delayed. See how to charge late fees for the late fee mechanics.
