A deposit is a payment the customer makes before work starts, credited toward the final price. Contractors use it to cover materials bought for the job and to hold a place on the schedule. Some states limit how much a contractor can collect up front on home improvement work.
Also called: Down payment, Upfront payment
A deposit does two jobs. It covers money you'll spend before the work starts, like special-order equipment or materials, so you aren't financing the customer's project. And it turns a yes into a commitment: a customer who has paid has a stake in keeping the date.
It's credited toward the price, not charged on top, and it's different from the other payments on a job:
Base the deposit on what you'll spend, or stand to lose, before the job starts, not on a round percentage someone quoted you. Then check it against any limit in your state.
Example: An HVAC contractor sells a $10,000 furnace and air conditioner replacement. The special-order equipment costs the contractor $4,000, so a deposit that covers it is $4,000, or 40% of the price. If the job's state caps deposits below that, the contractor can take the smaller deposit allowed and, where the rules permit, bill a progress payment when the equipment arrives. The numbers are made up for illustration.
When there's little to buy in advance, the deposit's main job is holding the date.
Example: A detailer books a $1,200 ceramic coating that takes a full day, two weeks out. The deposit is $200, credited to the price, with a written policy agreed at booking that says what happens to it if the customer cancels late or doesn't show. The numbers are made up for illustration.
On the estimate or contract, spell out:
A clear scope of work makes it obvious what the deposit and the balance pay for. If the job changes, adjust the total with a change order and show the deposit as already paid against the new total.
How much deposit to ask for goes deeper on limits and contract wording.
