Why the deposit matters more than you think
A deposit does three jobs at once. It funds the materials you have to order before you earn a dollar. It filters out the customer who was never going to move forward — a homeowner who won’t put money down is telling you something. And most importantly, a paid deposit is a decision: that customer stops shopping your competitors, because they’re now invested in you. On big-ticket work, the deposit isn’t just cash flow — it’s the moment the job becomes real.
First: check your state’s rules
Before you settle on a number, know that several states cap the deposit a home-improvement contractor can collect — some as a percentage of the contract, some as a flat maximum, and some trades carry their own rules. This guide can’t give legal advice; your state contractor board’s website can. Two universal rules that keep you safe everywhere: put the deposit in the written contract, and give a receipt.
How much to ask for
Where the law doesn’t set the number, common practice runs from around 10% on larger contracts to a third — or more — when the job front-loads custom materials that can’t be returned: windows cut to size, cabinets, a special-order unit. The honest logic to use (and to say out loud): the deposit should cover what the job costs you before your labor starts. Customers accept a number with a reason behind it far more easily than a number alone.
When to ask: the moment they say yes
The single biggest deposit mistake isn’t the amount — it’s the delay. The moment a customer accepts the quote is the moment their commitment is highest. Every day between “yes” and money changing hands is a day for second thoughts, competing bids, and a spouse’s cold feet. Ask at acceptance, as a natural part of the same conversation — not in an invoice three days later.
What to say: two scripts that work
The ask fails when it sounds apologetic. It lands when it sounds like procedure — because for a professional operation, it is. Two versions you can use as-is:
“Great — let’s get you on the schedule. We take a deposit of [amount] to lock in your dates and order materials, and the balance is due when the work’s done and you’re happy with it. I’ll text you a link — you can pay it right from your phone.”
“To get your materials ordered this week, we’ll need the deposit by Friday — after that I can’t hold the install dates. The link’s in your text thread whenever you’re ready.”
Notice what both do: they tie the deposit to something the customer wants (dates, materials), state it as standard procedure, and make the payment method effortless. No justifying, no discounting, no “if that’s okay.”
Make paying it frictionless — this is where deposits die
Most “deposit problems” are actually payment-friction problems. “Mail us a check” adds a week and a trip to the post office. “We’ll swing by to pick it up” costs you a drive. An emailed invoice lands in spam. Every hour of friction gives the yes time to soften. The fix: a payment link in the text thread the customer already has with you, payable in a couple of taps — card, Apple Pay, Google Pay, or bank transfer for the bigger numbers. When paying takes thirty seconds, deposits arrive the same day they’re asked for.
This is the part Plinth automates end to end: the quote goes out by text, the deposit link rides the same thread, the money lands in your own account, and the balance gets a polite automatic reminder when the work wraps. See how Plinth handles payments.
If the customer hesitates
A brief pause is normal; a hard refusal is information. For the hesitant-but-serious customer, offer structure instead of a discount: a milestone schedule (deposit, mid-job payment, balance at completion) keeps their exposure low and your cash flow moving. For the customer who won’t put anything down on a five-figure job — that’s usually not your customer, and the deposit just saved you from finding out the expensive way.
The checklist
- Check your state's deposit rules once — then set your standard.
- Size the deposit to your real pre-labor costs, and say the reason out loud.
- Ask at the yes, in the same conversation.
- State it as procedure, tied to dates and materials.
- Send a pay-by-text link — never wait on a check.
- Put it in the contract, give a receipt.
- Hesitation → offer milestones. Refusal → walk away grateful.
