CASH FORECASTING

CONSTRUCTION FINANCIAL FORECASTING SYSTEM, FORWARD-LOOKING VISIBILITY THAT ACTUALLY WORKS.

QUICK ANSWER

A cash flow forecast built once and never updated isn't a forecast. It's a historical record of what the business looked like on the day it was built. The forecast that works as a management instrument is updated weekly from actual transactions, tied to the current project schedule so a start date slip moves the revenue projection with it, and kept at two time horizons: 13 weeks for cash management and 24 months for strategic planning. The difference between those two things is the difference between checking a weather forecast from last Tuesday and checking today's.

Nobody abandons a forecast on purpose. The spreadsheet gets built during a tight month, it works, and then updating it turns out to mean rebuilding it. Two schedule changes and one new contract later, the model describes a business that no longer exists, and the owner is still making calls off it. That's worse than having nothing, because nothing at least feels like nothing. The answer is an owner: somebody whose job is to update it every Monday from what really moved through the bank.

THE DEFINITION

WHAT IT MEANS.

A financial forecasting system is a forecast that gets updated weekly from actual transactions, stays tied to the current project schedule, and is kept at two horizons: 13 weeks for cash management and 24 months for strategic planning.

WHAT WE SEE IN THIS BUSINESS

WHY THE SPREADSHEET STOPPED BEING TRUE.

01

Built once, never updated, produces false confidence

Most subcontractors who have attempted cash flow forecasting built a spreadsheet once. It was accurate for about 30 days, until the first project schedule changed, the first GC paid late, and the first new contract was signed that wasn't in the model. The spreadsheet never got updated because updating it means rebuilding it, and after 60 days it's a historical document dressed up as a forecast. An owner relying on it's making decisions from a model of a business that no longer exists, which is more dangerous than having no forecast at all.

02

It's not tied to the project schedule

When a project start date slips, the revenue projection has to slip with it or the forecast is wrong from that morning forward. In a standalone spreadsheet nothing moves on its own, so every schedule change has to be re-entered manually and most of them never are. That's why a forecast in a schedule-driven business goes stale faster than the owner expects it to.

03

The owner is the one producing it

A forecast the owner builds competes with everything else the owner does, so it gets updated when there's time and there's never time. The forecast has to be owned by the CFO function, with the owner reviewing it rather than producing it. That one change is usually what turns a forecast from a side project into an instrument the business runs on.

THE ARITHMETIC

WHAT IT LOOKS LIKE IN DOLLARS.

How accurate each horizon has to be

At 13 weeks, the forecast should be accurate within 10 to 15% on any given week. At 24 months, it should be directionally accurate within 20 to 25% on any given month. The precision requirement decreases as the time horizon extends, and the decision-making value doesn't.

What compounds

A financial forecasting system that has been running for 24 months contains two years of actual transaction data, 24 months of billing event history by GC, and a validated working capital model for the business at its current revenue. That data produces progressively better strategic decisions, because it's built from what really happened rather than from what was assumed at the start.

HOW SPM FIXES IT

THE FOUR COMPONENTS THAT MAKE FORECASTING RELIABLE.

Weekly transaction entry as the data foundation

Actual receipts and disbursements get entered weekly, so the forecast rolls forward from actual and not from estimate. Last week's real numbers replace last week's projections every Monday. That single habit is what keeps the model alive.

Project billing schedule from the current SOV and schedule

Each active project is mapped to its next 13 billing events with expected payment dates, and the map gets updated when project schedules change. A pay app that moves two weeks moves the cash with it. Nothing depends on somebody remembering to adjust the model later.

Overhead and fixed costs mapped by week

Payroll, rent, insurance, and the other fixed costs are mapped to the specific week they hit rather than averaged monthly. Averaging is what hides the week where two payrolls and an insurance renewal all come due together. The forecast has to know which Friday is the hard one.

LOC utilization tracked week by week

Available against drawn LOC sits inside the forecast rather than in a separate note nobody opens. Any week where the projected cash balance drops below the minimum floor triggers a draw planning conversation in the Monday review. The draw becomes a decision made in advance instead of a phone call made under pressure.

Two horizons, used for two different kinds of decision

The 13-week cash forecast drives the operational calls: which weeks need a LOC draw, which collections calls have to happen before a payroll week, and whether a vendor payment can be deferred. The 24-month forecast drives the strategic ones: whether the business has the working capital to support projected revenue growth, when to increase the LOC, and whether a new hire is financially sustainable. Both get reviewed in the monthly strategic meeting.

Core

You stop guessing.

You get the CFO work. Job costing built against the way you estimate, a 13 week cash forecast, monthly WIP, and a meeting every month that ends in decisions rather than a report.

Your bookkeeper keeps doing the books.

Executive

You stop touching the books.

Everything in Core, and we run the bookkeeping and the controllership as well. Nobody in your office is answering coding questions or chasing a reconciliation at month end.

We do the books. No payroll.

Strategic

Every job shows its margin while it's still running.

Everything in Executive, plus the job costing and WIP platform set up, loaded with your cost codes, and managed for you every month. You never have to learn it.

We do the job costing.

COMMON QUESTIONS

FREQUENTLY ASKED.

Within 10 to 15% on any given week. At that level the forecast tells you this week has adequate coverage, next week needs a LOC draw, and the week after that collections have to accelerate. Those are actions you can take. A forecast that's directionally correct but 25% off on any given week still prevents the Thursday night payroll surprise. Perfect accuracy isn't the goal, early warning is.
Start with the 13-week forecast. Map every known cash inflow for the next 13 weeks, which is expected pay app collections by project from your current AR aging. Map every known outflow: weekly payroll, the vendor payment schedule, loan payments, and lease. The balance by week is your first forecast and it will be rough. Update it next Monday from actual transactions, and it improves every week. By week 8 it's a reliable management instrument.
Yes. The 13-week cash forecast is produced weekly from actual transaction data and updated billing projections. The 24-month forecast is produced monthly from the backlog revenue schedule and the overhead cost model. Both are reviewed in the monthly strategic meeting, where the 13-week drives tactical cash decisions and the 24-month drives LOC sizing, hiring decisions, and bid strategy.
