How to Ask for a Deposit as a Contractor (And Actually Get It)

How to ask for a deposit as a contractor: say it at quote time, make it structural, and collect it before you spend a cent on materials. That is the whole answer. Everything else is the detail.

Most contractors struggle with this because they frame it as asking for a favour. It is not. The deposit is how the business works. When I was running maintenance contracts across London housing associations, every job had a payment schedule before a single operative dropped their tools on site. That is not greed. That is cash flow - and cash flow is the difference between a business and a job.

This is really a conversation about construction arbitrage - the model where you hold the contract, your subbies do the work, and you keep the margin in the middle. If you are running that model at any scale, you cannot fund jobs personally. The deposit is not a nice-to-have. It is how the float stays healthy while three jobs run at once.

Why you must take a deposit on every job

Materials hit your account before the first day on site. Labour on account means wages go out before invoices come in. If you are coordinating subbies, you may be paying their retainer before the client has handed over a penny. Every job you start without a deposit is a personal loan from you to the client.

The second reason is harder to say out loud: a deposit filters clients. A client who refuses to pay anything upfront on a $15,000 job is telling you something. Not necessarily that they are dishonest - but that they either do not understand how construction businesses work, or they are testing whether you need the work badly enough to start without security. Neither is a situation you want to be in on day one.

The deposit does not guarantee payment. It guarantees that the client has skin in the game before you do.

How much deposit to ask for as a contractor

(Figures in USD - the model and the math are identical in any currency.) For most residential work in markets without a statutory cap, 10% to 25% is the accepted range. Smaller jobs at the higher end, larger jobs at the lower end, because the total amount still protects you without front-loading the client unfairly.

Where special-order or custom materials are involved - bespoke joinery, imported tile, custom steel fabrication - you can legitimately push the deposit closer to the actual material cost. Some contractors take a separate materials deposit and a separate mobilisation deposit. That is clean and defensible.

Legal deposit limits by country

Some markets set hard legal limits on what a contractor can take upfront. Exceed them and you risk losing your licence, facing fines, or having the contract voided. Check the rules for your specific state, province, or country - the table below covers the rules I have been able to verify against authoritative sources. Always confirm with your local contractor licensing board, because rules change and local exceptions apply.

This table is a starting point, not legal advice. Rules change, local exceptions exist, and commercial work often operates under different rules than residential. If you are in doubt, check with your licensing board or a construction lawyer in your market.

How to word the deposit request

The mistake most contractors make is asking for the deposit after the client says yes. By then it feels like an extra demand. Present it as part of the terms when you hand over the quote.

Something like this works: 'We require a 20% deposit to confirm your start date and order your materials - that amount is deducted from your final invoice. The balance is due on practical completion.'

That is it. No apology. No 'if that is okay with you'. You are telling them how it works, not requesting permission. If you say it like it is your first time saying it, the client hears doubt. If you say it the way you tell someone the job will take three weeks, they hear confidence.

• Put the deposit amount in the contract. Not just the percentage - the actual figure. '$3,200 deposit due before work commences.'
• Link it to a start date. 'Your confirmed start date is [date] once the deposit is received.' That makes it operational, not just financial.
• Send the invoice with the contract. Make paying easy. A client who receives a contract with no clear payment instructions adds friction to themselves.
• Never start without it. This is the one that costs people. One exception, and the rule is gone.

What to do when a client refuses

Some clients genuinely push back on deposits because they have had a bad experience with a cowboy who disappeared with their money. That is a fair concern. The way you handle it separates you from the problem.

Acknowledge it: 'I understand that. A lot of people have had bad experiences. That is why we always confirm the start date and materials order in writing when the deposit comes in, and we send photos when deliveries arrive on site.' You are not giving in - you are showing them that your deposit means something real gets done with it.

If a client flatly refuses any deposit on a significant job and you cannot resolve it, that is a choice. You can reduce the deposit to a token mobilisation amount, you can ask for materials to be paid direct to the supplier, or you can walk. On a $50,000 job, walking is sometimes the right call. The clients who cost you the most money are always the ones who started by telling you they did not trust you.

For the bigger picture - how to price jobs so the margin is there whether you collect on day one or day thirty - read the guide on how to stop losing money on construction jobs. And if you are dealing with a client who paid the deposit and then went quiet, the client doesn't pay guide covers your options.

Progress payments on larger jobs

A single deposit is not enough on any job that runs for more than a couple of weeks. You need a payment schedule, and the schedule needs to be tied to milestones the client can see, not to dates you pick.

The logic is simple: you should never be more than one stage ahead of the money. If you are three stages in and they are still on stage one payment, you are funding their renovation and they are losing nothing by dragging it out.

This is the same principle behind construction arbitrage itself: the middleman keeps the cash moving in one direction. You win the client, your subbies do the work, and the payment schedule makes sure you never put more in than you have taken out. That is how the model actually works at scale.
