Bookkeeper for Building Maintenance Companies

How does the money come in?

Building maintenance revenue comes in three forms, and each form has its own bookkeeping trap.

Some owners also take on property management work on top of the repair side. A property manager gets a percentage of the rent collected, which is a different business from a contractor that gets paid for the work itself. Keep those two separate so the money that comes from rent is the property management income, not more repair revenue.

On any of the three billing structures, if the invoice for the work lands one month and the cost of the work landed the month before, you are sitting on your own money. Your books need the job cost and the job value to converge, or the profit is never real.

Why do all costs have to land on a job?

The profit on a job appears only when the cost is recorded in the same bucket as the revenue for that job.

If labor, materials and equipment all pile into one general expense account, the monthly profit and loss will tell you the business came out ahead, but it will not tell you which job paid for the month. That is the question most owners are really asking at the end of the month: did that big flat rate make money or only look like it did?

The fix is simple to describe and it is the whole game of the trade: every job gets a number, costs get recorded against that job number when they happen, and at the end each job shows its own profit or loss.

Cash flow matters here as much as income. You pay costs before the jobs pay you, so a contract that looks good on paper can starve your bank account. The books give you the real picture of the whole year.

How do materials stay straight on a job?

The most common material mistake is counting the same set of parts in two different places.

Here is what happens. You buy the parts, the bill lands in the cost. Later you invoice the job at a flat rate, and that flat rate already has the material cost built in. If you then subtract the material amount from the invoice, the same parts appear twice: once in the price list and once inside the quote. We take the vendor bill as the real job cost when it comes in, and the quote becomes the income that the customer owes. The parts appear only once in the profit and loss report.

The same $40 fitting or hose is where it starts. If a small part goes into a miscellaneous category and never attaches to a job, the job quietly loses money and the books do not show it. Everything on a job has a job number, or it is overhead. There is no middle place.

What is a repair, and what is an improvement?

A repair and an improvement go into different columns in the books, and the IRS draws the line.

A repair that keeps the property in working order is a current living expense, so it lands on this year. An improvement that upgrades a system adds value it is a capital expense: it goes on the asset list and gets spread across future years instead. The IRS rule runs on a test it calls the unit of property: for a building, that is the whole structure plus each major system taken on its own, the plumbing, electrical, HVAC, an elevator or escalator if one is present, the fire protection, the gas distribution, and the security system.

Where it really matters is a job that starts out as a small leak and ends up bigger than the leak. If a job starts as repairs and ends up replacing part of a system, everything changes. A cost of $1,000 either goes against this year or gets spread across the life of the work. Your books do not draw that line, but they can present the job costs so that the question shows up when it needs to be answered.

What usually goes wrong with the books?

The most common failure is plain disorganization, and it drives every other error.

Receipts and invoices sit in a pile or in a phone until tax time, and then everything is sorted into whatever category seems easiest. When we take over the regular work, the materials are most often miscategorized: the receipt is not there, the invoice has no job number, and the job of materials never comes to be whole. The fix is a habit of the owner: put a receipt with a job, or at least write which job the work is for.

The second common pain is on the client list. Owners write about a customer who pays long after the terms, 90 days on a 15-day invoice, with the late fee ignored. That is a cash problem and the books are the loneliest place that shows it. A simple aging report, a list of each unpaid invoice and how many days it has been unpaid, makes the slow payer visible long before it breaks the month.

The third is the small material that never gets its job number, the same $40 trap as above. All three end at the same place: the books are only as good as the owners habits of feeding the jobs.

What should the numbers help you decide?

Pricing your next job is the single most valuable decision the books can support.

Owners in this trade regularly know they are underpricing but cannot say by how much. Advice from small business advisors keeps showing up: do not bid every job down out of fear, and price each quote for what the job requires rather than hoping the size of the price alone wins. That is impossible to do well if the old job costs are unknown. With a job cost and cost per billable hour in view, every bid starts from a real cost floor.

The next question is the busy one versus the profitable one. A full week of jobs with no profit is far worse than a short week with the right price. The books make that visible, and it is the only reason the monthly numbers exist.

The same job cost figures help the bigger no ones: should you add a second van or increase the workload with many smaller crews? Is the old truck costing more in repairs than a rental or a new one would? Income is the volume of a thin line, but the books tell you what the real bottom line is.

The trade runs on a margin that is thinner than people guess. That is exactly why the job has to be accurate in the books: the difference between a few extra tenths of margin is the difference between the month being real or not.
