Job Costing – 5 Reasons Construction Businesses Need to Use It

5 Reasons Construction Companies Need to Use Job Costing –

Even When They Think It’s a PITA

Yes, we all know that PITA means “Pain in the (backside).” But here’s why every construction company should be using job costing – it is crucial to achieving the profits that you deserve.

1. Use Job Costing to Work “Backwards” (From Anticipated Price Into Your Detailed Cost Estimate)

Job-Costing Can Help You with your estimatesAs a construction company owner, you may start out with an idea of what you’ll be able to reasonably charge for a home or job.

Why? Maybe you’re familiar with the neighborhood – and know you shouldn’t exceed a given price range. Or perhaps your customer has told you what they’re willing to spend…

Regardless of the “price cap”, if you want to hit your gross profit target for that home or job, you’ll need to work backward from your anticipated price. You can use the price to develop very specific cost targets for each element of the project.

Of course, as an experienced builder or remodeler, you’ll:

  • Include employee labor and burden costs.
  • Get quotes for materials and contractor costs.
  • Estimate equipment costs (yours or rentals).
  • Anticipate a “layer” of cost and related income for a typical set of customer-generated change orders.
  • Create a guesstimate to cover unforeseen contingencies.
  • Add your expected profit on the job.

You may also need to:

  • Factor in land and development costs (if applicable).
  • Compute selling costs (commissions, closing fees, etc.).
  • Consider background interest on land and construction loans (balances and time-frames will have an impact).

After your first rough estimate of cost and price, you’ll move on to a detailed review and ask yourself, “Is the estimate complete?” and “Is it realistic?”

If the estimate is missing any elements – or it’s not realistic for the current circumstance – sharpen your pencil and go through the process again. Yes, it takes extra time, but every mistake will come straight out of your pocket.

After your final review, ask yourself, “Will I still be able to hit my desired gross profit margin?”

Estimating is your first pit-stop – and where profits are frequently won or lost… So, if your estimate shows that you won’t hit your gross profit margin, STOP!

Don’t lose the race at the starting gate!

2. Job Costing Enables You to See Costs and Income for Each Job (Estimated, Actual, and Remaining on Purchase Orders)

When you’ve decided to move ahead on your project, it’s time to enter your estimated costs and income into your job costing tracking system.

If you’re using QuickBooks desktop as your accounting software, you’ll use the “Item List” to do this. A well-designed Item List acts as an estimating “reminder” list and provides the structure you (or your bookkeeper) use to enter actual costs and income.

Your Item List provides the framing for job costing reports that reveal:

  • Detailed cost code estimates by job “stage” (e.g., Site prep, Foundation, Framing, etc.) AND by type of cost within each job stage (e.g., Employee Labor, Contracted Costs, Materials, Other Construction Costs, Equipment [if desired], Variances from PO [if desired]).
  • Income estimates for various pricing arrangements, including fixed price, time & materials, and “cost-plus” jobs.
  • Purchase Orders that are still “open” for each Job.
  • Actual costs and income (organized in the same way).
  • Estimated vs. actual costs and income reports (typically called “Variance” reports).

3. Job Costing Enables You to Control Profitability on Jobs – Before it’s Too Late!

No one wants to find out that they lost money on the job (or only made a gross profit of 1.5%!) – two or three months after a job is completed… 

Control Job Profitability – Before It’s Too Late

While enthusiasm runs high and a job is underway, it’s VERY easy to absorb (what seems like) small cost changes here and there. Those minor changes and random over-runs (plus unforeseen gremlins) can mount up to large behind-the-scenes losses!

When you aren’t actively using job costing, you can’t see exactly what’s going on with the cost elements of a job WHILE IT’S HAPPENING. And that means you’ve lost your window of opportunity to influence the final outcome.

If you’re not reviewing “Actual” and “Estimated vs. Actual” detailed job cost reports, you’re working in the dark.

And when you’re working in the dark – it’s easy to experience the business equivalent of a painful stub of the toe or even a major fall down the stairs!

If you wait until the job has ended to run your job costing reports to see your final results tallied, it’s too late to recover.

Instead, your mantra throughout every job should be:

“Measure & Monitor (and fix), Measure & Monitor (and fix), Measure & Monitor (and fix!)”

When you do this, you’ll be amazed at what you’ll see and find and can influence as a job is underway. YOU will be in a position to make practical, cost-effective decisions. As a result, you’ll be able to stay focused on the target of bringing your project in on time – and on (or under) budget.

How many tens or hundreds of thousands of dollars could that be worth to your company? To your profitability? For your “take-home pay”? To your family?

4. AFTER Jobs Are Done: Job Costing Makes it Easy to Evaluate Results to Improve Future Operations

Here’s how my clients use their job cost reports after projects are completed.

They review and talk through what went right on the job, e.g.,

  • What processes worked well (and should be repeated in future jobs)?
  • Which costs came in under budget (they explore how and why)?
  • Who should be congratulated (or rewarded)?

Owners and project managers use job costing reports to start to dig into what did NOT go well, e.g.:

  • What processes did NOT go as anticipated? What do we need to change in the future?
  • Which costs came in over budget? Why did it happen, and how can we correct this in the future?
  • If we have any “people” or vendor issues, how should we handle those issues? Do we need to provide additional training and coaching? Or take more drastic measures?
  • Who’s in charge of making various changes? And what’s our timing for implementation?
  • When estimated and actual costs vary, estimators use actual financial results and details as a resource for future estimates.

5. Use Job Costing to Shape Company Direction and Design Your Bigger Future

With job costing, you will be able to SEE your exact gross profit dollars and percentages on each job. As you identify profit patterns for various types of work, you extract valuable, useful insights from your data.

Identifying these patterns makes a huge difference in how and where you direct your company resources!

Here are some examples of profitability analytics our clients have asked us to help them measure.

For instance:

  • Contrasting gross profits based on the type of jobs performed (e.g., kitchen, bath, deck, addition, etc.)
  • How profitability varies based on the size of jobs (for example, $1,000 to $5,000, $5001 to $25,000, $25,001-$50,000, etc., based on job sizes handled by the company)
  • Reviewing profitability split out by department, division, project manager, estimator, etc.
  • Comparing profitability by elevation or “model” (e.g., the Bluestone, the Brookview, the Woodland, etc.)
  • Looking at the profitability based on a community or subdivision

Job-Costing Data Can Shape Company Direction

Job costing helps company owners and financial managers see detailed AND summarized gross profit amounts and percentages.

When this information is visible and clear, you can focus your efforts on the most profitable types of work.

You can begin to steer clear of, and ultimately remove, low-margin jobs that aren’t worth the time and energy (often pain and suffering!) that you’ve invested in the past.

An analytics report is also of value when it’s time to make other big-dollar decisions.

For instance, you’ll want your job costing data at hand whenever it’s time to:

  • Expand (or contract) the size of your business.
  • Hire (or lay off) workers.
  • Focus on a niche.
  • Shift locations.
  • Expand divisions.
  • Broaden operations, or
  • Change your advertising or marketing messaging.
