Without proper job costing and overhead allocation, you are bidding blind. Five questions every contractor should be able to answer in under thirty seconds, and the report structure that delivers them.

Most growing contractors hit the same wall around three to five million in revenue. The team has scaled. The number of active jobs has scaled. The volume of decisions has scaled. The accounting system, however, has not. Quickbooks still spits out a single P&L for the whole business and a balance sheet that aggregates everything. The owner is being asked to make bidding and resource decisions with information that simply does not exist at the right level of detail.

The fix is job costing. Not the marketing-brochure version of job costing, but the actual practice of attributing every dollar of revenue and cost to a specific job, then producing reports that let you compare jobs apples to apples. Done well, it changes how you bid, how you negotiate, and how confident you feel making capital decisions.

The five questions your books should answer.

If your accounting setup cannot give you fast answers to the five questions below, you are operating with less information than your competitors who can. Each one is a window into a specific kind of business decision.

1. What is the gross margin on each active job, in real time?

For every open job, you should be able to see contract amount, costs incurred to date, billings to date, and percentage complete. From those four numbers, your accounting system should give you projected gross margin at completion. If a job's projected margin starts dropping mid-project, you want to know in week six, not at year-end.

2. Which jobs make money, and which jobs cost you money?

Every closed job should produce a final P&L showing actual revenue, actual costs (labor, materials, subs, equipment, overhead), and final profit. Aggregated over a year, that data tells you which types of jobs to chase more of and which to stop bidding. Most contractors are surprised by which jobs are actually their best (and worst) performers.

3. Are you over- or under-billed on each job?

Overbillings (you have invoiced more than you have earned) are normal and healthy. Underbillings (you have earned more than you have invoiced) are a sign of poor billing discipline and a red flag to surety underwriters. The job-cost system should surface this every month, by job, so it can be addressed before it becomes a pattern.

4. What does true overhead per labor hour cost you?

If you are bidding jobs by adding 10 percent for overhead because that is what you have always done, you are guessing. A real job-cost system tracks total overhead and divides it across direct labor hours, giving you a defensible burden rate. That number then lets you bid more accurately and price-compete confidently.

5. Which crews and project managers are most profitable?

This one is the hardest culturally and the most valuable strategically. Tracking profitability by crew or PM tells you who runs your most profitable jobs. That informs hiring decisions, bonus structures, and how you assign your best people to your most demanding work.

The reports that actually deliver these answers.

You do not need fancy software to get there, but you do need the right report structure. The four core reports we set up for every construction client:

QuickBooks, properly configured, can produce all of these. So can Sage 100 Contractor, Foundation, Procore, and several others. The choice of software matters less than the discipline of categorizing every transaction to a job at the time it happens, not at year-end.

The setup decision

Most contractors who ask us for help with job costing actually need help with the setup of their chart of accounts and items list. The software is fine. The problem is the configuration. Once that is right, the reports practically generate themselves.

What to do this quarter.

If your accounting setup is not giving you these answers today, the quickest path forward is:

Each one of these is a meaningful improvement. Together, they transform how you run the business. Most contractors who go through this process tell us they feel like they were running half-blind before, and they wonder why they waited so long to do it.
