Bookkeeping for Security Installers: Equipment Sales and Monitoring Contracts

What security installer books need to track

A security installer is two businesses in one. One side sells and installs the gear. Panels, cameras, sensors, locks, wiring and the labor to put it all in. The other side bills a monthly fee to watch the system and respond when it calls.

When both sides land in one income line, the story gets muddy. You can not tell what the installs earned. You can not tell what the monitoring earns. You can not tell whether a busy month of installs covered the cost of the trucks and the crew. You can read more about how we keep these streams apart on our bookkeeping service page.

Here is what a clean month looks like.

How equipment sales show up in your books

An equipment sale is not one number. It is the gear, the labor and the markup. You buy the panel and the cameras. You pay the crew to install them. You bill the customer for the whole job. The difference is what the install earned.

The clean way is to book the sale to an equipment income line and the gear to a cost of goods line. When you do, your profit and loss shows what the installs earned on their own. You can see whether the markup is holding up as material prices move.

The messy way is to book the gear, the labor and the sale all in one overhead pile. Now the install looks free and the overhead looks huge. When the owner asks why the month felt busy but the bank did not grow, no one can point to the number.

Here is what to keep straight.

• **Book the equipment sale to an income line: ** not to one mixed sales line.
• - **Book the gear to a cost of goods line: ** so the install profit shows on its own.
• - **Book the install labor to labor cost: ** crew pay for installs sits apart from monitoring costs.
• - **Tag each job: ** so you can see what one install earned from start to finish.

How monitoring contracts show up in your books

A monitoring contract is the monthly fee a customer pays you to watch their system. It comes in every month for as long as the contract runs. Some contracts renew on their own. Some renew once a year. Some run month to month.

Monitoring revenue is steady. It does not jump around the way install sales do. That is the whole value of it. A month with no installs can still pay the shop, because the monitoring checks keep coming.

The clean way is to book each monitoring payment to a monitoring income line, away from equipment sales. When you do, you can see how much the recurring side earns on its own. You can see whether it grows as you add accounts and shrinks as accounts cancel.

Here is what to track.

• **Book monitoring fees to a monitoring income line: ** not to the equipment line.
• - **Match the bank deposit to the contract: ** so the deposit ties to the account that paid.
• - **Watch the renewal date: ** so you know when a contract is up for review.
• - **Count active accounts each month: ** so the steady revenue is easy to see.

How to handle recurring monitoring revenue

Recurring revenue is the part that makes a security installer worth more than a one time installer. The same customer pays you every month, often for years. The books should show that growth, month over month.

When each monitoring payment lands on its own line, the number goes up as you add accounts. It goes down when an account cancels or a contract ends and is not renewed. A simple list of active accounts shows the trend.

The messy way is to book the monitoring fee into the same line as the install sales. Now the steady income hides inside the noisy install income. You can not tell whether the recurring side is growing or shrinking, because it sits with the swings.

Here is what a clean recurring view looks like.

How deposits and progress billing work

Most security installs start with a deposit. The customer pays a part of the price up front. You order the gear. You schedule the crew. You finish the install. Then the rest of the price comes in.

A deposit is not income the day it lands. It is money you owe until the work is done. When the deposit clears the bank, hold it as a liability, not sales. When the install is complete, move it to equipment sales. That way the sale lands on the day the work went out the door.

Some jobs bill in stages. A deposit, a payment when the gear lands, and a final payment at sign off. Each one needs to land on the job. When they do, the job shows what it earned from start to finish, and the deposit never sits as income before it is earned.

Here is what to keep straight.

• **Hold the deposit as a liability: ** do not book it as sales the day it clears.
• - **Move it to sales when the install is done: ** the sale lands on the day the work is complete.
• - **Tag each payment to the job: ** deposits, progress and final all sit on one install.
• - **Match the bank to the job: ** so no payment floats in general income.

How to separate equipment sales from monitoring revenue

The whole reason to keep the two streams apart is to see what each side earns. Equipment sales swing with the install calendar. Monitoring revenue is steady. When they sit apart, you can see both stories at once.

A month with a big install and no new monitoring accounts looks busy on the equipment line and flat on the monitoring line. A month with no installs but a few new monitoring accounts looks slow on the equipment line and up on the monitoring line. Both months are fine, but only the split books show you why.

When the streams sit together, the story is lost. You can not price the installs. You can not value the recurring book. You can not tell whether to hire another crew or to push harder on monitoring sales. The split books answer that.

When a monitoring contract ends

A monitoring contract does not run forever. Some end when the customer moves. Some end when the system is old and the customer upgrades or quits. Some end because the customer found a lower fee. Each one needs to come off the books when it ends.

The clean way is to mark the account inactive when the contract ends and stop the monthly billing. The monitoring income line drops by that fee, and the active account count goes down by one. The books show the loss right away, so the steady revenue number stays true.

The messy way is to keep the account on the list and the billing running after the customer left. Now the books show income that is not coming in, and the active account count is wrong. You can read more about how we keep these lists clean in the next section.

A situation we clean up

The canceled accounts still on the books

A security installer runs about two hundred monitoring accounts. Over a year, some customers move out or cancel. No one marks the accounts inactive, but the billing keeps running on paper. At month end, the monitoring income line looks higher than the bank deposits. The active account count says one number and the bank says another. The owner can not tell which accounts are real and which ones are gone.

Here is how we handle it. We pull the monitoring list and the bank deposits for the year. We match each monthly fee to the deposits that cleared. We mark the accounts that stopped paying as inactive. We stop the billing on the ones that left. We bring the active account count down to the real number. When we are done, the monitoring income line matches the bank, and the owner can see the true recurring revenue. We set up a rule so the next cancellation comes off the list the month it happens.

Mistakes we fix

• Equipment sales and monitoring fees in one income line
• Deposits booked as sales the day they clear, before the work is done
• Monitoring accounts that canceled but still show on the active list
• Install gear and labor buried in one overhead pile with no job tag
• Monitoring deposits not matched to the contract that paid them
• Progress payments not tagged to the job they belong to

Common questions

Do I book a deposit as sales the day it clears? No. Hold it as a liability until the install is done. Move it to equipment sales when the work is complete. The sale lands on the day the gear goes out the door.

Should equipment sales and monitoring fees sit in the same line? No. Book equipment sales to an equipment line and monitoring fees to a monitoring line. When they sit apart, you can see what each side earns on its own.

How do I track a monitoring contract that ends? Mark the account inactive and stop the monthly billing. The monitoring income line drops by that fee, and the active account count goes down by one. The books show the loss right away.

How do progress payments work on an install? Tag each payment to the job. The deposit, the payment when the gear lands and the final payment all sit on one install. The job shows what it earned from start to finish.
