Construction Intelligence Brief
Why Revenue Recognition and Cash Flow Must Be Examined Separately
A contractor can report healthy revenue and profit and still run short of cash. Revenue is recognized as work progresses. Cash arrives when owners pay.
1. The business problem
We are growing and profitable on paper. Why is cash tight?
Construction accounting recognizes revenue as work is done, usually by percentage of completion. Billing and payment follow a different schedule, often with retainage and approval delays. The gap between the two is where cash problems arise.
Looking at the income statement alone, a contractor can be overconfident. Looking at cash alone, it can miss profit problems. Both views are needed.
2. What the evidence can reveal
Examining the two side by side takes a few measures:
- Calculated Revenue recognized and gross profit, from the income statement.
- Calculated Amounts billed and collected, from receivables.
- Calculated Over- and under-billings on each project: billed more than earned, or less.
- Information gap Payment terms, retainage balances and the age of receivables.
Underbilling means cash has been spent for work not yet billed. Overbilling means cash was collected ahead of work, which can be a source of funds or a hidden liability.
3. Investigate the problem
In the synthetic contractor, Calculated revenue recognized grew 12.0% to $51.5M, but gross profit fell from $3.90M to $2.90M. Growth in recognized revenue came with falling margins.
Illustrative An illustration, with invented numbers, shows how the gap forms. On a $10 million project that is 50% complete, revenue recognized is $5 million. If the contractor has billed only $4 million, there is $1 million of underbilling: costs were paid, revenue was recognized, and the cash has not come in. Add retainage withheld by the owner and the gap widens.
Calculated The portfolio is also mid-stream: Maple Street Apartments is 71.0% complete after growing recognized revenue 43.0%, and Harbor Logistics Warehouse is 64.0% complete. Information gap The demo has no billing or collection data. Comparing recognized revenue with billings and collections on each project is the check to add.
4. Explore the interactive experience
Investigate it yourself.
Project Performance Dashboard: a project portfolio dashboard with estimated final margins, a scenario simulator for change orders and costs, evidence-linked answers from APIS, and a sample brief, all on synthetic data.
The experience below is built on a synthetic contractor, “Demo Builders Inc.” Nothing in it is real, so you can explore freely.
- Select Maple Street Apartments. Its recognized revenue grew a great deal and its margin fell. What could that mean for cash?
- In the Scenario tab, raise activity by 10%. More work means more cost paid before it is collected.
- Ask APIS what additional information would help validate these conclusions.
5. Evaluate possible solutions
Managing the gap means watching billing, collections and terms, not only profit.
6. What leadership should do next
Questions to answer
- How much is under- or over-billed on each project?
- How long do owners take to pay?
- How much retainage is held?
- What does the cash forecast show?
Data to gather
- Billings and collections by project
- Aging of receivables
- Retainage balances
- Cost-to-complete estimates
Steps to take
- Compare earned revenue with billings monthly.
- Chase the largest gaps.
- Forecast cash by project.
- Review with the lender if needed.
7. Engage Two Pillars
Improve Project Visibility and Financial Control
Two Pillars can help contractors investigate project portfolio, margin, estimating, cash-flow and operational performance using your own project data. A good first step is a cash-versus-profit review of the project portfolio that surfaces billing gaps.
