TL;DR
On this page
You delivered the work. The client went quiet. And because you never took a deposit, you are holding finished files, an unpaid invoice, and no leverage. A deposit invoice is how you stop that from happening again. It gets you paid, partly, before you start, so the worst case is a client who walks away early, not one who walks away with everything. The norm for service work is 25 to 50 percent of the total. Below is the full mechanic, from the clause in your proposal to the final invoice that deducts the deposit, plus the scripts to ask a new client without sounding distrustful.
This pairs with how to write a freelance invoice that gets you paid faster, and sits inside the wider freelance invoice templates by profession guide. This post is specifically about the deposit half of the job.
What a deposit invoice actually is
A deposit invoice is a request for part of the payment before any work happens. That timing is the whole point, and it is what separates it from a normal invoice.
A deposit invoice is how you get paid, at least partly, before you start work.

A standard invoice goes out after you deliver, when your leverage is gone and all you can do is ask. A deposit invoice goes out before you deliver, when the client still wants the work and is motivated to pay. You are not inventing a fee. You are moving part of the existing fee to the only moment when you have any negotiating position at all.
The reason this matters is simple, and a client who has never stiffed a freelancer rarely thinks about it. HoneyBook frames the risk plainly:
Let's say you've been working for weeks or months on a project. If the client decides to pull the plug without paying you halfway through, there are no guarantees you'll see a dime.

The deposit caps that downside. It also filters out the clients least likely to pay, because the people who balk hardest at a reasonable deposit are often the same people who would have balked at the final invoice too.
How much to ask for
For service work the accepted range is 25 to 50 percent of the project total. Billed's freelance invoicing guide puts the reasoning in one line: a deposit of 25 to 50 percent upfront covers your initial time investment and confirms the client's commitment.
Within that range, project size is the usual deciding factor. HoneyBook's rule of thumb is to require 33 percent of the project total for larger projects and 50 percent for smaller projects. The logic: on a small, fast job, half upfront is easy for the client to swallow and covers most of your exposure. On a large job, a single 50 percent payment is a big ask, so a smaller deposit plus milestone payments spreads the commitment without scaring anyone.
Push toward the top of the range, or add milestones, when:
- The client is brand new and you have no payment history with them.
- They are based overseas and recovering an unpaid invoice would be impractical.
- The project front-loads your effort, so most of your work happens before the final invoice.
That calculation has its own post; the point here is that the number lives in your proposal, before any invoice goes out.
The deposit term goes in the proposal first
The single most common mistake is inventing the deposit at invoice time. By then it reads as a surprise, and surprises about money make clients nervous. The deposit should already be agreed before you send anything to pay.
Put one line in the proposal or contract: the deposit amount, what it represents, and that work begins once it clears. Something like "A 50 percent deposit ($1,500) is due on signing. The remaining balance is invoiced on delivery." When the deposit invoice arrives the same day, it is not a request, it is the thing you already agreed to. FreelanceDesk's proposal builder keeps that clause in your standard template so it is never the part you forget. For the wider structure, see how to write a freelance proposal that wins.
The deposit invoice sequence, step by step
Once the deposit is agreed, the rest is a fixed sequence. Follow it the same way every time and the paperwork reconciles itself.
1. Send the deposit invoice the day the contract is signed. Not before, because there is nothing agreed to bill against yet, and not days later, because the gap is where momentum dies. The signing and the deposit invoice are one moment. Number it as the first invoice in the job, for example INV-2026-018, so the sequence is unambiguous.
2. Wait for it to clear before you start. This is the discipline that gives the deposit its meaning. If you begin work and chase the deposit afterward, you have recreated the exact situation the deposit was meant to prevent. The cleared deposit is your green light.
3. Invoice any milestones along the way. On larger projects, each milestone gets its own numbered invoice. Every one of them is part of the same sequence, and every one references the deposit so the running total stays clear.
4. Reconcile on the final invoice. This is the step the template-download pages skip. The final invoice shows the full project total, deducts the deposit already paid as its own line, and lands on the balance due:
| Line item | Amount |
|---|---|
| Project total | $3,000 |
| Less deposit paid (INV-2026-018) | -$1,500 |
| Balance due | $1,500 |
The final invoice shows the full total, minus the deposit already paid, with the remaining balance due. The detail that keeps it clean: reference the deposit invoice number on the final invoice, so the client can reconcile both documents at a glance. You can send both the deposit invoice and the reconciled final invoice from FreelanceDesk's invoice generator, which carries the deposit line and numbering through for you.
pro tip
Keep one numbering sequence per client or per year, never a fresh number per document type. A deposit invoice of INV-2026-018 and a final invoice of INV-2026-022 read as one continuous story. Two separate sequences (DEP-01 and INV-01) invite the client to lose track of what they already paid.
The script: asking a new client without sounding distrustful
The fear with a first-time client is that asking for money upfront signals you do not trust them. The fix is to frame the deposit as standard process, not personal suspicion, because that is what it is. Keep it short and matter-of-fact:
Thanks for confirming. To get you booked in, I send a deposit invoice for 50 percent ($1,500), and I start as soon as that clears. The remaining balance is invoiced on delivery. The deposit invoice is on its way now.
Notice what it does not do. It does not apologize, it does not over-explain, and it does not ask permission for something already agreed in the proposal. The deposit is presented the way a hotel presents a card-on-file: a normal step in starting work, not a negotiation.
If the project is large and 50 percent feels heavy, offer the milestone version in the same breath: "For a project this size I usually split it, 25 percent to start, 25 percent at the halfway mark, and the balance on delivery." You are not lowering your protection, you are pacing it.
When the client says "I don't pay deposits"
Some clients, especially larger companies with procurement rules, genuinely cannot pay a deposit. That is a real constraint, not always a red flag, and you have two clean responses.
The first is to substitute structure for the deposit: shorter payment terms (net 7 instead of net 30), milestone invoicing so you are never more than one milestone out of pocket, or a signed contract with a kill fee that compensates you if they cancel. The second is to weigh the risk honestly. A slow, manual invoicing process compounds this exact exposure. FreshBooks found that businesses slower at invoicing were more than twice as likely to lose revenue from unpaid invoices, 22 percent versus 9 percent. A no-deposit client on long terms with a sluggish invoice is the worst-case stack. If you take that work, tighten everything else.
When a deposit truly is not possible and the balance still goes unpaid, the playbook shifts to collections. See how to deal with late-paying clients and the freelance payment collection mistakes that quietly stall invoices.
Two siblings round out the deposit decision: how much deposit to ask for sets the number before you send the invoice, and if scope grows mid-project, a change order bills the extra rather than absorbing it.
The deposit invoice is the cheapest insurance you have
It costs you one line in a proposal and one invoice sent on signing day. In return, it turns the catastrophic outcome (weeks of work, nothing paid) into a survivable one (a client who walks before you have done much). Agree the number in the proposal, send the deposit invoice the moment the contract is signed, start when it clears, and reconcile it on the final invoice with the deposit deducted and its number referenced. Do that every time, and getting paid stops being a gamble you take after the work. It becomes a step you complete before it.
