Growing operating companies almost always feel constrained by cash. The instinct is to look outside — a bigger line, a raise, a bridge loan. The finance function’s first move is to look inside. In most mid-market operating businesses, the cash to fund the next stage of growth is already sitting in the working capital cycle — trapped, not missing. Finding it doesn’t require a bank. It requires the visibility and discipline the founder-CFO seat generally can’t produce.
Where cash actually hides inside an operating business
Working capital is the difference between what the business owns in short-term assets (cash, receivables, inventory) and what it owes in short-term liabilities (payables, accruals, current debt). In a healthy operating company, the working capital cycle turns fast enough that cash is generally available to fund operations and modest growth. In an owner-run business that has outgrown its finance function, that cycle is almost always longer than it should be — and every day of extra cycle time is cash that could be doing something else.
The specific places to look are consistent across industries:
Receivables that could be collected faster
Days sales outstanding — the average number of days between invoicing a customer and collecting the cash — is the single most actionable working capital lever. In most owner-run businesses, DSO is 10 to 30 days longer than it needs to be. The reasons are recognizable: invoicing that lags the delivery date, terms that were set once and never enforced, no cadence for following up on aging balances, no policy for slow-paying accounts, and no visibility into which customers are quietly extending themselves at the business’s expense. Every ten days of DSO reduction on a mid-market P&L releases meaningful cash — permanently.
Inventory that turns too slowly
For businesses that carry inventory, turns are where cash accumulates without anyone noticing. Slow-moving SKUs, safety stock built for a demand pattern that changed years ago, work-in-process that hasn’t been reconciled to a real completion timeline, finished goods that quietly age past sellability. Owner-run finance functions typically track turns as a blended number. Real cost accounting turns each SKU into a decision — hold, discount, discontinue — and each decision releases cash.
Vendor terms that nobody has renegotiated
Payment terms with vendors get set when the relationship starts and generally never move without someone raising them. A supplier who currently gives you Net 30 will often extend to Net 45 or Net 60 for a business that has grown into meaningful spend with them. Early-pay discounts that were fine at initial volume become suboptimal at scale. Nobody renegotiates because nobody has the standing or the numbers ready to make the case.
Deposits, retention, and prepayments
In industries where deposits, retention, or prepayments are normal — construction, custom manufacturing, professional services — the structure of those flows is where cash quietly stalls. Retention balances that have aged past release dates and nobody billed. Deposits that could be structured higher without breaking the customer relationship. Prepayment discipline that would smooth the cycle if it existed.
What the finance function actually does with this
Visibility alone doesn’t release cash. The finance function’s job is to build the visibility and then run the process to convert it into cash on the balance sheet. In practice, that means:
- An AR aging cadence with owner-level accountability on the accounts that matter, not just a report that lands in an inbox.
- SKU-level inventory analysis with clear disposition on slow movers and a maintained cycle count program.
- A vendor terms review annually, not opportunistically — with the data ready to support the ask.
- A rolling 13-week cash forecast that turns working capital movement into a decision surface rather than a monthly surprise. (See the 13-week cash forecast piece.)
- Deposit and retention structures reviewed for whether they match the current risk profile of the business.
Why growth without this discipline stalls
Every hire, every new location, every additional SKU, every larger customer, adds working capital demand. Businesses that grow without releasing working capital along the way end up in the same place regardless of top-line: cash-constrained, dependent on credit lines that never quite keep pace, unable to say yes to opportunities that would compound. The finance function that manages working capital deliberately is the finance function that lets growth actually feel like growth — instead of like running harder in place.
How this fits with the rest
Working capital is one of the first categories the Financial Discovery Assessment™ surfaces — usually alongside pricing, forecasting, and credit capacity. The Assessment produces the Financial Heat Map System™: a dollarized, prioritized view of exactly where cash is trapped and what it will take to release it. See the pillar piece for how working capital fits into the broader arc of what a real finance function surfaces that the founder-CFO can’t see from the inside.
