Why Take a Deposit and How Much
Why this matters
A deposit is the difference between funding a customer's project out of your own pocket and having them put skin in the game before you order parts. On a big job, the materials alone can tie up a large slice of your working capital for weeks. A deposit covers that exposure, filters out tire-kickers, and locks the customer to the date. Charging too little leaves you exposed; charging too much scares off honest buyers. Getting the percentage right is a real skill.
What a deposit actually protects
A deposit does three jobs at once, and it helps to know which one you are solving for:
- It covers your hard costs. If you have to buy materials or special-order equipment before you can start, the deposit should at least cover what you are out of pocket the moment you commit.
- It commits the customer. A buyer who has paid nothing can cancel on a whim and cost you a held slot and a restocking headache. A buyer who has money down shows up.
- It signals seriousness both ways. Asking for a deposit tells the customer this is a real contract, not a maybe. It also tells you, by their reaction, whether you have a buyer or a browser.
How much to ask for
There is no single right number; the percentage should track the risk of the specific job. A useful way to think about it:
| Job profile | Typical deposit posture | Reasoning |
|---|---|---|
| Small same-day service, no special parts | None, or pay-in-full at completion | Little capital at risk; collecting at the door is enough |
| Mid-size job with stock materials | A modest share of the total | Covers materials and commitment without a big ask |
| Large project, special-order or custom equipment | Larger share, up to roughly the cost of materials | You are out real money before work starts |
| Long multi-week build | Deposit plus progress billing | No single payment should leave you deeply underwater at any stage |
The principle: never let your unpaid exposure on a job exceed what you can comfortably carry. The deposit is the first lever; progress billing on bigger jobs is the second.
Tie the deposit to your costs, not a flat habit
A flat percentage applied to every job is easy but blunt. A job that is mostly your labor needs a smaller deposit than a job that is mostly expensive equipment you have to buy first. Look at where the money goes. If a third of the ticket is special-order material, your deposit should comfortably clear that material cost so you are never financing the customer's parts. If the job is almost all labor you control day by day, you can ask for less and collect the rest as you go.
What the law and good practice expect
Deposit rules vary by location and trade. Some jurisdictions cap deposits on certain home-improvement work or require that deposit money be handled a specific way. Two safe habits regardless of where you operate: put the deposit terms in writing on the estimate (amount, what it covers, and your cancellation and refund policy), and be clear about whether the deposit is refundable and under what conditions. A deposit term that lives only in your head is a dispute waiting to happen.
Make the ask cleanly
Customers accept deposits far more easily than owners expect, as long as the ask is framed as routine. Present it as a normal step: "To get on the schedule and order your materials, we collect a deposit, and the balance is due at completion." State the amount, state what it covers, and offer an easy way to pay it (a card or a payment link beats waiting on a mailed check). A deposit that is fast and painless to pay gets paid; one that requires a trip to the bank stalls the whole job.
When to skip the deposit
Not every job needs one. Small jobs with no upfront cost, repeat customers with a clean payment history, and accounts on established terms can often skip it. The deposit is a risk tool, not a tax on every customer. Reserve it for jobs where you have real money or a real schedule slot at risk, and let your good customers feel the trust you have earned with them.
