Building maintenance companies earn money in three distinct ways and your bookkeeping needs to reflect that. You have monthly service contracts with recurring revenue, on-call or emergency work billed per visit, and project-based jobs like lobby renovations or system upgrades. If all of that revenue lands in one bucket, you have no idea which part of the business is actually profitable.

Set up separate income accounts or classes for each contract type. Monthly contracts go under recurring services. Emergency and on-call work goes under service calls. Larger one-time jobs go under project revenue. This separation is what lets you see your monthly recurring revenue as its own line on management reports. MRR is the foundation of a facility services business because it tells you what baseline revenue you can count on before any additional work comes in.

Every contract or job should carry its own cost tracking. When a crew goes to a building, the labor hours and materials used on that visit need to be coded to that specific contract or work order. If you send two workers to replace lighting fixtures at a property on Tremont Ave, those hours and the cost of the fixtures get assigned to that building’s account. Without this, you might think a contract is profitable when the labor and materials are actually eating the margin.

Work orders are the connection between what happens in the field and what shows up in your books. Each service visit or project task should start as a work order that captures the building, the scope, the crew hours, and the materials used. That work order then flows into your accounting system as a cost entry tied to the right job. In QuickBooks, this means using the job costing features so every expense hits the correct customer and contract.

On the expense side, your chart of accounts should break out direct costs from overhead. Direct labor, materials, and subcontractor costs are tied to specific jobs. Overhead like your office rent, vehicle insurance, equipment leases, and administrative salaries are not. Keeping these separate lets you calculate gross margin per contract and gross margin per contract type. That is the number that tells you whether your monthly contracts are priced correctly or whether your on-call rates need to go up.

For a building maintenance operation managing multiple properties across the Bronx or other boroughs, you also want your reports to show revenue and costs by location or property. This is easy to set up with classes or locations in QuickBooks. A building that generates $3,000 a month but costs $3,200 in labor and materials needs to be renegotiated or dropped. You only see that when the books are structured to show it.

Reconcile weekly if possible. Building maintenance involves a lot of small purchases at hardware stores and supply houses and those transactions pile up fast. Weekly reconciliation catches duplicate charges and miscoded expenses while they are still fresh. If you are running crews across multiple buildings every day, waiting until month-end to sort through everything is a recipe for errors.

If setting up this structure feels like a lot, that is because it is more involved than basic bookkeeping. But the payoff is clear visibility into which contracts make money and which ones don’t. Bronx bookkeeping services built around your contract types and job costing needs will give you the financial picture you need to price work correctly and grow the business on solid ground.
