Start Collecting Deposits on Every Job — Not Just Big Ones

The Habit You Don't Have

Three no-shows in a week. Spring of 2009. I had three guys left, a service van with 140,000 miles on it, and enough cash to make payroll exactly twice before I'd have to call Diane and tell her I was laying somebody else off. Every booked job mattered. Not the way guys talk at a trade show about taking care of customers. In the way where a burned service window was four hours of labor I couldn't sell again.

Two of those three no-shows had something in common. Neither one had given me a dime.

That was the moment I stopped treating deposits like something you ask for when the number gets scary. Every job. New install, boiler service, a snake call on a backed-up kitchen drain. Every job gets a card. I ran it that way until I sold the book in 2018 and I'd do it the same way again tomorrow.

Most Shops Only Collect Deposits When the Number Scares Them

The pattern I see in small residential shops: deposits are for the $12,000 boiler replacement. Maybe the $8,500 tankless conversion. The job where the material cost alone makes you nervous. For everything else — the service call, the same-day repair, the leak diagnosis — you send someone out on good faith.

That ain't a policy. That's a habit you never looked at.

I watched this up close during the worst stretch at Smith Mechanical. By early 2009, my builder receivables had stretched from 45 days to over 110. I was staring at the AR side so hard I missed that the same problem was happening on the front end. No deposit on small work meant I was pre-financing every decision a homeowner made to let me come out. They hadn't committed a dollar. They could cancel at 7 a.m. and all they'd lost was a phone call. I'd lost a day.

You're absorbing all the risk of the booking and they're absorbing none of it. That's not goodwill. That's a subsidy.

Guys I know running the hardest cash-flow situations are almost always running zero deposit discipline on smaller work at the same time. Bleeding from both ends — long on the AR side, soft on the front end. Fixing one without the other keeps you underwater, just in a different spot.

The No-Show Problem Is a Deposit Problem

Simple test. If someone asked you right now how long you could cover payroll, truck notes, and overhead with zero new revenue — what's your answer? Not what you'd want it to be. What it actually is.

If the answer isn't 90 days, you've got a cash problem. I came to that number the hard way, sitting at a desk in late 2008 trying to figure out exactly how long I could keep three guys working if no new calls came in. Two payroll cycles was the answer. That is a hostage situation, not a business. The shops running thin like that are the same ones eating two or three blown service windows a week and never asking for a card to hold.

Those aren't separate problems.

The homeowner who books a call without paying anything behaves exactly like the GC who hasn't signed a lien waiver. Nothing is real to them yet. I watched this on the builder side for years — retainage held past substantial completion, pay-when-paid clauses, invoices sitting at 75 days while I got "next Friday" on the phone. I kept working. Which meant I kept letting them bet that I would. I finally fired Whitman Builders in 2011 over $61,000 in stretched receivables — took 38 cents on the dollar in the bankruptcy. Should have walked eighteen months earlier. I didn't because I'd never made the cost of walking away feel real.

Same dynamic on the service side. The customer who cancels at 6:45 a.m. — after you've loaded the van and rearranged the day — didn't wake up trying to hurt you. They just did the math. Rescheduling costs them a phone call. It costs you four hours you can't sell back. You built that imbalance. A deposit shifts it. Not punishingly. Just enough that canceling has an actual cost on their side.

Yes, Even Same-Day Calls

I know the objection. You'll tell me you'll lose the customer if you ask for a deposit on a $200 service call. That it feels aggressive. That the shop down the street doesn't do it.

The customer you lose over a $75 booking deposit was never going to pay you cleanly anyway.

I mean that. In my experience, the customers who push hardest against a deposit are the same ones who show up at the invoice wanting to negotiate, or who dispute the diagnostic fee because you didn't "fix anything," or who pay NET-30 at 60 days and act like that's normal. They're not bad people. They're people who figured out — from you and from every other shop that never asked — that the risk lives on your side.

"We don't take deposits on small stuff" is the same logic as "we don't do change orders on small stuff." Both sound reasonable. Both bleed you out slowly. The small stuff is where discipline either lives or dies.

I've heard the customer-experience argument. Usually from software sales reps who want you to believe that a polished booking flow — the automated confirmations, the two-way texting, the "your tech is on the way" photo notification — is the answer to no-shows. I've seen shops running Housecall Pro and ServiceTitan with clean booking flows still getting stood up regularly, because the flow never asked for money. It just asked for a time slot. A confirmation text confirms nothing except that the customer read the text.

I've written about both those platforms before. Neither one is bad. But a booking experience that costs the customer zero dollars is a zero-commitment booking. The point of asking for a card isn't bureaucracy. It's that the customer now has something on the line.

What Actually Happened When I Did It

After the second no-show in the same week in early 2009, I wrote one rule on a notepad: no booking confirmed without a card on file. Not always charged upfront — but a card on file, with a clear statement it applied to the job.

I expected the worst pushback from longtime residential customers. People who'd been calling since 2006, 2007. Felt like they'd earned something with the shop. The first time I held the line with one of them — a woman who'd had us out three times, always paid clean — she paused. You could feel it through the phone. She asked if it was new. I said yes. She said okay.

She showed up. Paid the invoice. Never mentioned it again.

The ones who walked — and a few did — I recognized later. Not right away, but later. They were the same type of guy: the one who'd asked for a discount on a water heater the year before because he "paid cash." The woman who'd left a one-star review over a diagnostic charge she thought should've been waived when we fixed it same-day. People who'd already told me, in other ways, how they saw our arrangement.

I didn't know that then. I just needed every booked job to show up. That necessity pushed me into a policy that turned out to be right. I only understood why later.

How to Structure It So It Doesn't Feel Like a Shakedown

The language matters. Not because you're working anyone — because vague language creates resistance and clear language doesn't.

"We require 50% upfront before we dispatch" sounds like a ransom note.

"We hold your appointment with a card on file — the deposit goes straight toward your balance when we're done" sounds like a scheduling system. Which it is. Same outcome. Very different phone call.

It's a scheduling confirmation, not a credit check. The customer isn't being vetted. Their slot is being held. That's honest and it's also what gets the least pushback.

On amounts: for service calls and small repairs, use a flat number. Somewhere between $75 and $150 depending on your market and your call-out cost. Don't do percentages on small jobs. A percentage opens a conversation about what the job might cost before you've seen it, and now you're estimating over the phone on an undiagnosed problem while the customer anchors to the first number that floats by. Flat deposit, no negotiation surface. "We take $100 to hold the appointment" and then you wait.

For bigger jobs — installs, replacements, anything over $3,000 — percentages make sense. Thirty to fifty percent is standard. In writing, signed, before anything gets ordered.

When someone objects on the phone, don't apologize. Don't explain at length. One sentence: "That's how we confirm all our appointments now — it goes toward your bill either way." Then stop talking. The pause is theirs. Most of them fill it with a card number.

What to Do Monday Morning

Start with new bookings only. Don't call your regulars and announce a policy change — that creates friction where you don't need it. New customer calls in, new system applies. Your existing customers hit it naturally the next time they call. By then it's just how you do things.

Write one sentence for whoever takes your calls. Tape it to the monitor: "We hold appointments with a card on file — it goes toward your invoice when we're done. Can I grab that now?" Practice it until it sounds like something a person says, not something a policy document says. The hesitation around asking for deposits is almost entirely social. Same feeling as asking for payment at the door — awkward the first few times, then it's just how you do business.

One thing to do before you set amounts: find out what your state says about deposit handling for home improvement contracts. I know Massachusetts has specific language on this. I'm not going to guess at what other states require because I'd be guessing. Call your attorney, ask one question, spend twenty bucks. Do that before you start, not six months in when you find out the $100 booking deposit technically needed to be disclosed differently.

Start Monday. New bookings only. One sentence on a notepad. Check the rules first.

FAQ

What percentage should I charge as a deposit on a service call?

Skip the percentage on service and repair calls. Use a flat number — somewhere between $75 and $150 depending on your market and your minimum call-out cost. Percentages on undiagnosed work force a price conversation before you've seen anything. Flat deposit is a clean transaction. It holds the appointment, it applies to the invoice, and it doesn't open any door you don't want opened. Save percentages for installs and replacements where you have a real number.

What if a customer refuses — do I turn them away?

Yes. Politely, but yes. A customer who won't hand over $100 to hold a service appointment is showing you something about how the rest of the relationship will go. Hold the line once, don't apologize, explain it's how you confirm all your appointments now, and let them decide. The customers worth keeping generally come around. The ones who walk are usually the ones who would have made your invoice process painful anyway.

Can I charge a deposit on emergency calls when the customer is already stressed?

Yes, and you should. A burst pipe at 11 p.m. is the highest-leverage moment you have to ask for a card — the customer has maximum urgency and you have maximum justification. Frame it the same way: "I'm getting someone out to you tonight. I'll hold the call with a card on file and it goes toward the bill." Stressed customers in emergencies aren't more fragile about this than you think. They want someone coming. The card is incidental to that.

What if the job comes in smaller than expected?

Apply the deposit to the invoice and refund the difference if you took more than the job cost. This is rare with flat-rate deposits on service calls because the deposit usually sits well below the final invoice. If somehow you come in under — you found a simple fix — refund the balance promptly and without drama. That customer now knows you're straight with them.

Do I need to update my contracts?

Probably yes, at least a little. Your written authorization should state the deposit amount, what it applies toward, and your refund policy if you can't do the work. For bigger jobs, add language covering cancellation after materials are ordered. A clean paragraph in your standard work order covers most of it. Get your attorney to look at it once, especially if your state has specific home improvement contract requirements. Before you start, not after.

Won't this hurt me competitively if other shops don't charge deposits?

Maybe with customers who shop on friction alone. In practice, the customers who pick you over a competitor because you don't require a deposit are the customers most likely to cancel, dispute the invoice, or pay slow. Customers with a real problem and a burst pipe don't care about $100 against the bill — they care that someone's coming. The shops in my area didn't require deposits when I started doing it. I didn't lose the work I wanted to keep.
