Demystifying construction accounting: Revenue recognition and job costing explained

Introduction: Why does construction accounting feel so hard?

Let’s be honest, accounting for construction is complex. You’re juggling long projects, unpredictable costs, and more paperwork than most industries. It’s no wonder many contractors feel overwhelmed or frustrated.

The good news: You’re not alone. And you don’t have to stay stuck.

At Knowify, we’ve seen trade contractors—electrical, plumbing, HVAC, painting, remodeling, and more—transform their businesses by getting a handle on two essential pillars: revenue recognition and job costing.

We’re here to make these topics approachable, actionable, and most importantly, useful for you. As Steve Coughran, construction profitability expert and founder of Coltivar, shared on The Cost Codes Show:

“Construction accounting can be so complicated… every single project is almost like a business in itself. And the CEO of that business is almost like the construction manager or whoever’s running the job, right? So it gets very complicated early on.”

—Steve Coughran, Coltivar

But with the right approach and the right tools, you can master these fundamentals and set your business up for long-term success.

The fundamentals of construction revenue recognition

Why construction Is different from other industries

In most businesses, accounting is straightforward: sell a product, collect payment, record the revenue. Construction? Not so much.

  • Projects span weeks, months, or even years
  • Change orders and scope shifts are the norm
  • Progress payments and retainage complicate cash flow

As Steve put it:

“In construction, we accept money upfront for mobilization… then you go and do the job the next month, and you’re billing against that money you already collected last month. Now there’s a timing difference between your revenue and your cost.”

—Steve Coughran

This is what makes construction accounting unique, and why a solid grasp of revenue recognition is essential.

The two main methods: Completed contract vs. percentage of completion

Let’s break down the two most common methods for recognizing revenue in construction:

1. Completed contract method

  • What it is: Revenue and expenses are only recognized when the project is 100% complete.
  • When it’s used: Typically for short-term projects (under two years), or when there’s significant uncertainty in estimating costs.
  • Pros: Simple, defers taxes until job completion.
  • Cons: Can distort financials for long-term projects, making it harder to spot issues early.

2. Percentage of completion method

  • What it is: Revenue and expenses are recognized based on the project’s progress, usually measured as costs incurred to date divided by estimated total costs.
  • When it’s used: Required by the IRS for most long-term contracts (IRC Section 460).
  • Pros: Matches revenue with expenses, gives a clearer picture of financial health.
  • Cons: Requires accurate job costing and regular updates.

“If you’re not doing percentage of complete billing or the correct revenue recognition, then your financials are a mess and it’s so hard to run a business that way.”

—Steve Coughran

Key takeaway: Percentage of completion is the industry standard for larger or longer projects. It provides a more accurate, up-to-date view of your business.

Common pitfalls and how to avoid them

Even experienced contractors can fall into these traps:

  • Early recognition: Recording revenue before work is performed.
  • Delayed billing: Letting change orders or progress payments pile up, hurting cash flow.
  • Underbilling: Not billing for all work performed, which can lead to profit fade.

How to avoid them:

Job costing: The heart of construction profitability

What is job costing and why does it matter?

Job costing is the process of tracking every dollar and hour that goes into each project. Contractors commonly track labor, materials, subcontractors, equipment, and sometimes, overhead.

Why does it matter? Because you can’t improve what you don’t measure.

“If you’re not maintaining a WIP and if you’re not doing job costing, you’re going to be dead. Like your business, maybe you’ll survive… but eventually you’re going to die. You have to have this iterative process: bid, build, measure, and adjust.”

—Steve Coughran

With accurate job costing, you can:

  • See which jobs are truly profitable
  • Spot overruns before they sink your bottom line
  • Improve your bids with real data, not guesswork

Scenario:

Suppose you bid 1,000 labor hours for a commercial remodel, but your field team logs 1,200 hours. Without job costing, you might not catch this until the project’s over, and the profit’s gone.

Setting up for success: Data collection and accuracy

Accurate job costing starts with disciplined data collection:

  • Log every hour worked to the correct job and phase
  • Record material and equipment costs as soon as they’re incurred
  • Track change orders and extras in real time

Common challenges:

  • Lost receipts
  • Missed timecards
  • Untracked extras

Practical tip:

Knowify’s mobile app makes it easy for field crews to clock in, submit receipts, and record jobsite activity on the spot, no more paperwork lost in the truck.

Turning data into insights: Reporting and analysis

Collecting data is just the beginning. The real value comes from using it to drive better decisions.

  • Regular job cost reports help you spot issues early, not after it’s too late.
  • Analyze variances between estimated and actual costs to improve future bids.
  • Visual dashboards (available in Knowify) make trends and red flags obvious at a glance.

“You have to have bid, build, measure and adjust as a circular process… If you’re not doing job costing and you’re not reviewing that and you’re making adjustments and you’re constantly tweaking, you’re literally just guessing.”

—Steve Coughran

Bringing it all together: Technology’s role in simplifying accounting

How modern tools remove the guesswork

Manual spreadsheets and paper timecards belong in the past. Today’s construction businesses need automation, integration, and real-time information.

Knowify was built for this:

  • Streamlined revenue recognition: never worry about mistimed income again
  • Integrated job costing: track labor, materials, subs, and overhead in one place
  • QuickBooks sync: eliminate double entry and reduce errors

And we don’t just leave you to figure it out alone. Every Knowify subscription includes award-winning onboarding and U.S.-based support.

“…without a WIP you’re totally guessing on your numbers. The WIP’s gonna tell you what have you actually earned, what are your costs to complete, which is super critical, and it’ll show you your overbilled and underbilled position and ultimately your cash flow on jobs.”

—Steve Coughran

No more flying blind. No more sleepless nights.

Conclusion: Confidence through clarity

Construction accounting is never “easy,” but it’s absolutely manageable. By understanding revenue recognition and job costing, you take control of your business’s story.

You don’t have to be a finance expert to know your numbers. But you do need to know the story behind them.

“For a business owner, you don’t have to be a nerd… it’s understanding the story behind the numbers, that’s the difference.”

—Steve Coughran

Every step you take toward clarity and control is progress, celebrate that. With the right mindset and the right tools, you’re building a business that lasts.
