A FORECAST IS ONLY AS GOOD AS THE JOB DATA UNDER IT.
A cash forecast isn't a spreadsheet skill. It's five inputs, dated honestly, resting on job data that holds up.
A construction cash forecast estimates the future cash inflows and outflows, and it does that with five inputs: project billings, expected collections, payroll cycles, material purchases, and subcontractor payments. Put together, those tell an owner how cash will move through the business over time rather than how it moved last month. Forecasting earns its place in construction because projects involve large spending up front followed by delayed payments, so without one a contractor can commit to a project that creates real financial strain without knowing it until the strain hits. The forecast is only as reliable as the project information underneath it, which is why job costing and WIP reporting are the prerequisites rather than the optional extras. Companies that build the forecasting discipline early tend to grow more smoothly and get fewer financial surprises.
The point worth holding onto is that forecasting is a discipline you run every week. A forecast produced once, admired, and left alone is worth nothing. One produced on a schedule, corrected against what happened, and used to make a decision is what changes the business.
This post covers what belongs in a cash forecast and what has to be true underneath it. Read The Construction Financial Forecasting System for the complete treatment, worked figures included.
WHAT A CASH FORECAST SHOWS YOU.
A construction cash forecast estimates the future cash inflows and outflows. It's a forward-looking document, which already makes it different from most of what a contractor receives at month end. It typically includes projections for:
This information helps owners understand how cash will move through the business over time.
WHAT FORECASTING CHANGES IN CONSTRUCTION.
Construction projects often involve large expenses up front followed by delayed payments. Without forecasting, contractors may unknowingly commit to projects that create temporary financial strain, and by the time the strain is obvious the commitment is already signed.
Forecasting provides early visibility into those situations. Early is the whole value of it, because a problem you can see six weeks out has several answers and the same problem on the Thursday before payroll has one.
CONNECTING FORECASTING WITH PROJECT DATA.
Accurate forecasts depend on reliable project information. Job costing and WIP reporting provide the data needed to estimate the future billing and spending, which means a forecast is downstream of both of them rather than independent.
When those systems work together, cash forecasting becomes far more reliable. When they don't, the forecast inherits every problem in the cost data and presents it in a tidier format, which is worse than having no forecast because it looks authoritative.
PLANNING FOR GROWTH.
As subcontractors grow, financial forecasting becomes more important rather than less. Companies that develop the forecasting discipline early often experience smoother growth and fewer financial surprises, and the ones that wait usually build it during a crisis, which is the most expensive time to learn anything.
