How much deposit should a trade contractor collect before starting a quoted job?

What a deposit is for, and what it is not

A deposit does two honest things. It covers materials you have to buy before the job starts so you are not floating the purchase on your own cash, and it confirms commitment so you can hold a schedule slot without wondering whether the customer will vanish. It is not a profit advance, and customers can usually tell when it is being used that way. Related: Following Up on a Quote Without Being Pushy

Start from the materials number on your quote. If the job requires a special-order unit, custom cabinetry, or a large lumber package, the deposit should at least cover that. If the job is mostly labor with parts from your truck stock, a smaller commitment deposit is enough. Tying the amount to something visible on the itemized quote makes it easy to explain.

Sizing it: common patterns and state limits

Many residential contractors work with a percentage of the total, and the fraction varies widely by trade and job size. Some states cap how much a home improvement contractor can collect up front, and some require specific contract language whenever a deposit is taken. Before you set a standard, check your state's contractor licensing board or attorney general guidance, since these rules change and penalties can be real.

For smaller service jobs, many contractors skip a deposit entirely and simply require payment on completion, which keeps friction low. For mid-size jobs, a deposit that covers materials plus a modest commitment amount is typical. For larger projects, a deposit followed by progress payments tied to milestones (rough-in complete, inspection passed, final walkthrough) spreads risk fairly for both sides.

Stating it so nobody is surprised

The deposit belongs on the quote, not in a conversation after acceptance. Show the total, the deposit amount, when it is due, and what triggers the balance. "Deposit due at signing, balance due on completion" is enough for a short job. For anything with milestones, list each payment and the event that triggers it. Vague terms like "half down" without a date invite different interpretations.

Say what the deposit does for the customer, too. It locks in the schedule slot and lets you order materials immediately. When a customer understands that the deposit is why the job starts next Tuesday instead of next month, resistance drops. Digital acceptance with a deposit request in the same step removes the awkward second conversation entirely.

Refunds, cancellations, and keeping records

Decide in advance what happens if the customer cancels. Materials already ordered and non-returnable are reasonably kept; unearned labor generally is not. Write this in a sentence or two on the quote. Some states have cooling-off periods for contracts signed in the home, and your language should respect them. Fair, clear terms rarely get tested because customers who see them tend to trust you more. Related: How Photos Make a Quote More Persuasive

Keep the deposit tied to the quote record with the date received and the method. When the final invoice goes out, the deposit should appear as a credit line so the customer sees the math. That single line, deposit received on such a date, prevents most "I thought I already paid for that" conversations.
