When an electrician should skip the deposit entirely
Start with the jobs that need no deposit at all, because that is most of a service electrician's week. A deposit exists to cover money you have already committed. If you have not committed any, there is nothing for it to do.
A diagnostic call, a fixture swap, adding an outlet on a circuit that already runs to the room, anything you can quote, do, and finish in one visit with parts off the truck, gets no deposit. You buy nothing ahead of time, you carry no cancellation risk, and you are getting paid on completion before you leave the driveway. Asking for a deposit on a $250 job adds a payment step and a small awkward conversation, and it protects you from nothing. Take the whole amount when the work is done.
The deposit question only becomes real when there is a gap between the day you spend money and the day the customer pays you. That gap is where electricians get hurt, and closing it is what the rest of this guide is about.
Size the deposit to your exposure, not to a percentage
On a job big enough to need a deposit, you are paying for two things before the customer pays you anything. The first is materials: the panel, the breakers, the meter base, the wire and conduit, the EV charger, the fixtures. You buy those on your account at the supply house or on a card, and that money is gone the day you order. The second is the permit. On work that needs one, the licensed contractor pulls the permit and pays the fee, and that happens up front, before the inspection that lets you collect.
Add those two numbers. That sum is the floor for your deposit. Not a percentage you picked because it sounded normal, but the actual dollars you will be out before the job earns you anything.
Example: a 100-to-200-amp residential panel upgrade. Say the panel, breakers, meter base, and wire run $1,100 at the supply house, and the permit is around $180. You are roughly $1,280 in the hole before you have turned a screw. Quote the whole job at $3,200 and a deposit that just clears that exposure is already 40 percent. Quote the same job at $4,500 and the identical $1,280 is 28 percent. The percentage moved twelve points and your real risk did not move at all. That is why the percentage is the wrong unit. Ask for the dollar figure that covers the gear and the permit, and talk about the percentage only if the customer brings it up first.
Permit fees are set locally and vary more than electricians expect. They commonly land anywhere from the low tens of dollars to a few hundred, and higher in some metros, but you never have to guess, because most jurisdictions publish the schedule. The City of San Diego's development services department and the City of Everett, Washington both post their permit fee schedules online, electrical work included, and your own building department almost certainly does too.1 Look the number up before you quote and the permit stops being a figure you round.
One more piece of the same idea: special-order materials. A specific panel a customer asked for, a long-lead meter base, anything the supply house will not take back, is exposure that does not disappear if the job does. When the materials for a job are special-order, the deposit should clear them in full, with no exception, because a cancellation otherwise leaves you holding parts you can neither use nor return.
Big jobs: let the inspections set your payment schedule
On a multi-day job, a rewire, a service change with a panel, anything that runs past a single visit, do not take one deposit and then wait for the rest at the end. Stage the payments. Electrical work gives you something most trades have to invent for themselves: built-in milestones that someone other than you signs off on.
A rough-in inspection and a final inspection are externally verified checkpoints. When the rough-in passes, a city inspector has confirmed that real work is done and done correctly. That is the easiest progress payment you will ever collect, because you are not asking the customer to take your word for how far along the job is. The inspection is the proof.
A clean schedule for a larger residential job looks like this. A deposit before you start, sized to the materials and the permit. A progress payment when the rough-in passes inspection. The balance when the final inspection clears and you energize the work. Each payment is tied to a stage anyone can verify, and none of them rests on a conversation about whether enough has been done to justify the money.
There is a legal reason to tie payments to completed stages rather than to dates on a calendar. California restricts a contractor from collecting progress payments that run ahead of the value of the work actually performed, and the Contractors State License Board has issued reminders to that effect.2 Other states have their own versions of the rule. Billing against an inspection you have already passed keeps you on the right side of all of them, because by definition the work is finished before the money is due.
The state laws that cap your deposit
Sizing the deposit to your exposure tells you what you need. State law sometimes tells you what you are allowed to ask for, and the two numbers do not always agree.
California is the clearest example. On a home improvement contract, the down payment is capped at $1,000 or 10 percent of the contract price, whichever is less. That cap is triggered by the kind of work, not by your license class, so it covers electrical work that counts as a home improvement, the alterations, upgrades, and additions to an existing home, not just general remodeling. New residential construction is governed by separate rules. The cap is written into the state's Business and Professions Code, and collecting more than the limit is a misdemeanor, not a gray area.2
Put that against the panel upgrade from earlier. Your exposure was $1,280. On a $4,500 contract, California law caps the down payment at $1,000. The deposit you are legally allowed to take does not even cover the parts. That is not a loophole to work around, it is the law, and the way you stay whole is the staged schedule from the section above. A lawful down payment, followed by an early progress payment the moment the materials are delivered to the site or the rough-in passes, gets your money back into your hands without breaking the cap.
California is not the only state that caps residential deposits, and the states that do cap them do it in different ways, by percentage, by a flat dollar ceiling, or by tying the deposit to delivery of materials. Before you put a deposit figure on a quote, look up how your state's contractor or electrical licensing board handles it. You only have to do that lookup once for your state, and skipping it is how a deposit that felt reasonable turns into a complaint to the board that licenses you.
Put the deposit on the quote, not in a second phone call
A deposit becomes an argument when it arrives as a separate conversation. The customer hears a price, says yes to that price, and then gets a follow-up call asking for money before anything happens. That sequence makes the deposit feel like a surprise, and surprises about money make customers nervous.
The deposit should be a line on the written quote from the start. The job total, the deposit amount and what it covers, when each later payment is due and what triggers it. The customer reads the whole structure at once and agrees to all of it with a single signature. Nothing after that is a surprise, because all of it was on the page they signed.
The quote is also where a quote fee gets settled, if you charged one. Our guide on whether electricians should charge for quotes covers the credit-on-hire fee, the fee you charge for a serious project quote and credit back when the customer books. Show the fee, show it deducted, show the deposit, show the balance. A customer who can see the math laid out does not argue with it.
If you are still writing quotes by hand, this is the change worth making first. A quote that lays out the deposit and the payment stages in clean line items reads as the work of an electrician who has done this before, which is exactly the electrician a customer wants on a multi-week panel job.
Handling the customer who pushes back on the deposit
Some customers will push back on any deposit at all. Most of that stops with one calm explanation.
"The deposit covers the panel and the permit. I order the panel the day you approve the quote, and I pay the permit fee before the city will let me start, so I'm paying for both of those before I've earned anything on the job. Once the rough-in passes inspection there's a progress payment, and the balance is due when the final inspection clears." You are not apologizing and you are not negotiating. You are describing how the money moves, and for a deposit that plainly just covers your cost, the description is the whole argument.
Most people hear that and agree, because it is obviously fair. The customer who keeps fighting a deposit that is visibly nothing more than the parts and the permit is asking you to buy their electrical work with your money and trust them to pay you back. Going on what the trade sees again and again, that is the same customer who later disputes the final invoice and pays slow. The deposit did not cost you that job. It told you early what collecting the last payment was going to be like. When a final payment does drag, our guide on when to send invoice reminders covers the follow-up cadence that gets it in.
A deposit is not about pulling money out of every customer early. It is about not financing other people's electrical work out of your own checking account. Size it to what you are spending, stage it to the inspections on the big jobs, keep it inside your state's cap, and put the whole structure on the quote where the customer signs it. Do that and the deposit stops being a conversation you dread and turns into one line nobody questions.
