Bookkeeper for Security Guard Companies

Not every guard company runs the same way. Some are single location, some run mobile patrols, some staff events, and some mix in executive protection. The money and cost structure below is the shape most of them share, and where it changes from company to company that is flagged.

How does money flow in a security guard company?

Revenue is the hours you sell, and the client pays on an invoice cycle that runs behind the payroll.

A guard is on a post for 12 hours at a rate of $30 an hour brings in $360 for that shift. Multiply those hours across all posts and shifts, and you have you. The client rate itself is most often built from cost rather than from what the market will bear: take the true hourly cost of the shift, apply a small margin, and the rate becomes the asset a licensed data security professional wants. Security contracting guidance normally starts with the full cost of labor and materials, then adds a 3 to 5 percent margin. That means your books are the only place where the accuracy of that rate can be checked.

The two money cycles are not in step. Guards get paid on a recurring schedule, and the client pays when the invoice terms come due. Between those two dates, the work is done, the payroll is out, and you are carrying the shortfall. A niche is the invoice that the industry and financing system for this trade tells you how ordinary this timing gap is.

What are the real costs?

Labor is the largest cost, and the wage on the timesheet is only the start.

On top of each guard's base wage you carry the employer share of payroll taxes, workers' compensation insurance, and benefits. Industry material on the trade places the added burden at roughly 30 percent above base salary. Workers' comp is a large line of its own because the work is physical and sites carry real hazard. If you field armed guards, liability insurance for that work is separate and more expensive.

Materials and equipment are smaller but not nothing: uniforms, duty gear, and vehicle maintenance, and liability coverage. In a cost plus pricing model, every one of these has to land on the contract that generates the revenue, because the whole pricing thumb rests is cost plus a fraction. Misplaced costs do not move the company total much, but they move the margin calculation for individual contracts a lot.

What commonly goes wrong in the books?

The mistakes that hurt most are the ones that hide the true cost of a single contract.

• Stalled post orders. Guards work to written instructions for the site, and owners report those instructions sitting out of date for a year or more. Guards work hours, the payroll sits there, and nothing gets billed because the client never approved the work.
• Timecards that don't match the invoice. Hours worked, hours billed, and hours paid have to be one number. When they drift apart, the margin is dipping and it repeats every shift until someone catches it.
• Miscategorized costs in a price model that relies on operations. Fuel, gear, and insurance can be dumped into general overhead and stay there. General overhead is not bad by itself, but it hides which contracts are actually watching to more than they should.
• Contractors treated as employees or employees as contractors. The cost per hour is not the same, and a contract that uses its own staff costs differently from one that brings in a difference for nights and weekends.

What should you track per contract and per client?

The margin lives at the contract level, not in the company total.

The same $30 an hour billable rate can show a good margin on one end of a completed one and very little on another. The difference is the cost of that shift: the guard's wage and burden, plus any overnight, weekend and on-call provisions that a contract bears. When you look only at the total, a strong contract expects a weak one, and the decision about the second deposit contract permanently disappears.

Which reports matter and what do they support?

Four reports do most of the work.

A total only P&L does not answer the decisions that come up. It cannot tell you whether the client who forces two weekends a month is connected or only tiring you, or which rate on the sheet is underpriced. The breakdown has to be per contract and per client.

What decisions should the books actually support?

Hiring, bidding, and keeping or dropping a client are the big ones, and each one needs real numbers.

Hiring a new guard adds payroll from the first hour, while the revenue from that same work arrives weeks later. The books should tell you whether the cash in hand covers the short gaps before you risk the start of a job. A new contract should be priced from the true cost of the shift, not the company average, because the average hides the difference between a post that is cheap to cover and one that is not. And the decision to keep a client is not about the revenue. It is the profit after real cost, overtime hours and even calls. Letting one client calls that decision support the spreadsheet yourself almost missing the real point
