WORKING CAPITAL

CONSTRUCTION WORKING CAPITAL MANAGEMENT.

QUICK ANSWER

Working capital is what lets you mobilize a new job, absorb a slow GC, and grow without borrowing. Most subcontractors manage it by accident, building it in good years and spending it in tight ones. A common benchmark is 10 to 15 percent of annual revenue, so a $5M contractor should be holding $500K to $750K.

The number moves for reasons that have nothing to do with whether your jobs made money. A profitable year generates working capital and most of it goes back out as draws, bonuses and equipment before anybody works out what the business needed to keep. Then the next big job mobilizes and the money isn't there. That's not a profit problem, and cutting bids won't fix it.

THE DEFINITION

WHAT IT MEANS.

Working capital is current assets minus current liabilities: what you could turn into cash inside a year, less what you owe inside a year.

Working capital requirements grow with revenue, and not just in dollars. A $3M subcontractor needs less than an $8M subcontractor as a percentage of revenue as well as in absolute terms, because more revenue means more simultaneous mobilizations, more retention held at once, and a longer tail of receivables in play on any given Friday.

WHAT WE SEE IN THIS BUSINESS

WHERE THE MONEY GOES.

01

It gets distributed instead of retained

A profitable year generates working capital. Most of it gets distributed as owner draws, bonuses and equipment purchases before anyone calculates what the business needs to keep in reserve. The money was real and the year was good. There's just nothing left to fund the next mobilization with.

02

You don't know the number

Working capital is current assets minus current liabilities. Most subcontractors can't say what theirs is today, because nobody has calculated it and nobody watches it monthly. A number nobody reports is a number nobody manages.

03

The requirement grows as you grow

Getting bigger raises the requirement faster than it raises the profit that funds it. More jobs running at once means more mobilizations, more retention held, and more receivables outstanding on the same Friday. Growth is the most common reason a profitable contractor runs short.

THE ARITHMETIC

WHAT IT LOOKS LIKE IN DOLLARS.

The target

A common benchmark is 10 to 15 percent of annual revenue held in working capital. A $5M contractor should be targeting $500K to $750K. Below that, one slow GC and one mobilization hit in the same month and the line of credit becomes the plan.

HOW SPM FIXES IT

HOW IT GETS BUILT ON PURPOSE.

The working capital target, set from your revenue

The target is calculated from your trailing twelve months rather than borrowed from a rule of thumb, then held as a floor that distributions get measured against. Draws and bonuses come out of what's above the floor, not out of the floor.

Built through retained earnings, deliberately

Working capital grows by keeping profit in the business rather than distributing it. That's the only source. Faster collection improves the same number without needing retained earnings at all, which is why the collections work comes first: it costs nothing.

Reported monthly, in both tiers

The number is calculated and reported every month for every client, Core and Executive alike. It's not an Executive-tier extra, because a floor nobody sees isn't a floor.

Range reflects the three tiers below. Which one you're in depends on how much of the work you want off your desk. No payroll. No hidden line items.

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.

COMMON QUESTIONS

FREQUENTLY ASKED.

It depends how you buy it. Paying cash moves money out of current assets and into a fixed asset, which reduces working capital dollar for dollar. Financing it leaves the cash in place and adds only the next twelve months of payments to current liabilities, so the hit is much smaller. This is the single most common way a good year turns into a tight quarter.
AR is a current asset, so it counts toward working capital while it sits uncollected. Collecting faster doesn't change the total, it changes what the total is made of: cash you can spend instead of an invoice you're waiting on. That's why collections is the cheapest lever there is. It improves the position without requiring a single dollar of retained profit.
A common benchmark is 10 to 15 percent of annual revenue, so a $5M contractor should target $500K to $750K. The right number inside that range depends on how many jobs you run at once, how much retention is held, and how slowly your GCs pay. A contractor with four simultaneous jobs and 10 percent retention needs the top of the range, not the bottom.
