The Working Capital Blindspot: How Mike Ehrle Sees Small Businesses Strangling Their Own Growth
Written by Matt Emma
Revenue growth feels like success. More customers. Larger orders. Expanding operations. Business owners celebrate these wins and push for more. But Mike Ehrle has witnessed a pattern that repeats across industries: businesses achieving strong revenue growth while simultaneously sliding toward cash crisis because they've ignored working capital management.
Through his work at both Lumity and finparency, Ehrle has evaluated hundreds of small businesses. The pattern is remarkably consistent. Owners focus intensely on revenue and gross margins while paying insufficient attention to the cash conversion cycle. The result is growth that consumes cash faster than operations generate it, eventually choking expansion and creating vulnerability that could have been avoided through disciplined working capital management.
The basic mechanics are simple but often misunderstood. When you make a sale, revenue appears immediately on your income statement. But cash doesn't arrive until the customer pays, which might be 30, 60, or 90 days later. Meanwhile, you must pay for inventory, labor, and overhead long before that customer payment arrives.
This timing gap requires working capital—cash tied up in accounts receivable and inventory that isn't available for other uses. As sales increase, working capital requirements increase proportionally. Grow revenue 50 percent and you need roughly 50 percent more working capital to support that growth.
Many business owners don't internalize this relationship. They see growing revenue and assume cash flow will follow naturally. They increase spending on people, equipment, and facilities to support growth. And they're shocked when cash becomes tight despite strong sales.
The problem compounds when growth accelerates. The faster you grow, the more working capital you need. A business growing 10 percent annually might manage working capital from operating cash flow. That same business growing 40 percent annually almost certainly needs external financing because working capital demands exceed what operations generate.
Businesses that ignore this reality hit cash walls. They can't make payroll despite having substantial accounts receivable. They can't buy inventory needed to fulfill orders. They can't invest in capabilities required to sustain growth. And they sometimes face insolvency despite being profitable on paper.
Most small business owners track revenue, expenses, and profit but pay inadequate attention to working capital metrics. They know their sales figures and gross margins. They monitor operating expenses carefully. But they don't track days sales outstanding, inventory turns, or cash conversion cycle with the same rigor.
This measurement gap creates blindness to building problems. Accounts receivable aging extends gradually. Inventory accumulates slowly. Payment terms with vendors tighten incrementally. None of these changes trigger alarm by themselves, but collectively they squeeze cash flow until crisis arrives.
Ehrle emphasizes specific metrics that every growing business should monitor monthly:
Days Sales Outstanding (DSO): How long does it take to collect payment after making a sale? If this number creeps from 35 to 45 to 60 days, you're financing your customers' operations with your cash.
Inventory Days: How long does inventory sit before being sold? Increasing inventory days means cash tied up in unsold goods rather than available for operations.
Days Payable Outstanding (DPO): How long do you take to pay suppliers? While extending payment terms preserves cash short-term, excessive delays damage vendor relationships and can trigger unfavorable credit terms.
Cash Conversion Cycle: The combination of these metrics shows how long your cash is tied up in operations. A 60-day cycle means you need two months of operating expenses in working capital. An 90-day cycle means three months.
These metrics don't just describe current state—they predict future cash needs. When DSO increases, you know working capital requirements are growing before cash becomes tight. When inventory days creep up, you can investigate why and take corrective action before cash gets consumed.
The relationship to systematic management, as explored in earlier discussions of predictable growth, is direct. You can't manage what you don't measure. Businesses that track working capital metrics systematically can optimize their cash conversion cycle. Those that don't stumble into cash crises despite profitable operations.
Once working capital metrics are visible, specific interventions can improve cash flow without requiring external financing.
Accelerating collections directly reduces DSO. This might mean offering modest discounts for early payment, requiring deposits for large orders, or using payment terms as a negotiating variable. Many businesses accept slow payment as inevitable when aggressive collection discipline could significantly reduce working capital needs.
Inventory optimization reduces cash tied up in unsold goods. This requires understanding which products move quickly and which sit. Better forecasting, more frequent ordering of fast-moving items, and elimination of slow-moving inventory all improve inventory turns and free cash.
Strategic vendor relationships enable favorable payment terms. Vendors willing to extend 60 or 90-day terms effectively finance your operations. This requires building relationships based on reliability rather than simply squeezing suppliers on price.
These interventions sound simple but require discipline to implement consistently. Accelerating collections means having uncomfortable conversations with customers. Inventory optimization requires analytical rigor many small businesses lack. And strategic vendor relationships take time to develop.
But the payoff is substantial. A business that reduces its cash conversion cycle from 90 days to 60 days frees up a full month of operating expenses for other uses. That freed capital can fund growth, reduce borrowing, or provide cushion against unexpected challenges.
One specific working capital drain that business owners often underestimate is benefits costs. Healthcare expenses are typically paid monthly but employee headcount changes can lag revenue, meaning benefits costs often increase in step with growth.
Moreover, poorly managed benefits create hidden working capital drains. When employees use expensive emergency care because preventive care isn't adequately covered, claims spike unpredictably. When benefits don't meet employee needs, turnover increases, driving recruiting and training costs that consume cash.
Lumity's approach to benefits optimization directly impacts working capital management. By reducing benefits costs 20 to 30 percent while maintaining or improving coverage, businesses free up cash that would otherwise be trapped in inefficient spending. This isn't just expense reduction—it's working capital optimization.
The platform's predictive capabilities also help businesses forecast benefits costs more accurately, reducing cash flow surprises. When you know with confidence what healthcare spending will look like over the next 12 months, you can plan working capital requirements accordingly rather than getting surprised by unexpected claims.
This connects to the broader theme of data-driven transparency that Ehrle champions. Working capital optimization requires visibility into cash flows across all major expense categories. Benefits represents one of the largest, so optimizing this area has outsized impact on overall working capital efficiency.
When Mike Ehrle evaluates businesses through finparency, working capital efficiency significantly impacts valuation. Investors pay attention to cash conversion cycles because they indicate operational discipline and determine how much capital is required to operate the business.
A business with a 45-day cash conversion cycle requires substantially less working capital than an equivalent business with a 90-day cycle. This difference means the efficient business can grow faster with less capital, generates more free cash flow, and presents lower risk to acquirers.
Moreover, improving working capital efficiency creates value that shows up directly in valuation. If you're generating $2 million in annual revenue with $500,000 in working capital and you reduce your cash conversion cycle to need only $350,000, you've freed $150,000 of capital. For a business valued at 4x EBITDA, that's $600,000 of incremental value.
This connection to the four pillars of value creation is often overlooked. Business owners focus on revenue growth, cost containment, and operational improvements while ignoring working capital optimization. Yet improving cash efficiency can create as much value as any of the more visible value drivers.
Implementing rigorous working capital management requires discipline that conflicts with entrepreneurial instincts. Entrepreneurs want to say yes to growth opportunities. They want to support customers with favorable terms. They want to build inventory to ensure they never miss a sale.
These instincts aren't wrong, but they need to be balanced against cash realities. Saying yes to every growth opportunity when you lack working capital to support it leads to crisis. Offering generous payment terms to win business is fine if you have the cash to finance those receivables. Building inventory makes sense only if the inventory turns quickly enough to justify the cash investment.
Working capital discipline means making trade-offs: slower growth that you can finance versus faster growth that requires external capital; selective customer acceptance rather than pursuing every opportunity; and inventory strategies that balance availability against cash efficiency.
These trade-offs feel like constraints. And they are. But constraints enable sustainable growth while their absence leads to chaos. What Mike Ehrle has observed repeatedly is that businesses that accept working capital discipline grow more sustainably and ultimately reach greater scale than those that ignore cash realities until crisis forces correction.
For business owners who've been ignoring working capital, the first step is establishing visibility. Calculate your current cash conversion cycle. Measure DSO, inventory days, and DPO monthly. And track trends over time to spot deterioration before it becomes crisis.
Then implement systematic improvements. Accelerate collections through process discipline. Optimize inventory through better analytics. Develop strategic vendor relationships that enable favorable terms. Each intervention compounds, gradually reducing working capital requirements and freeing cash for growth.
The businesses that master working capital management grow faster, require less financing, command higher valuations, and sleep better at night knowing they aren't one bad month away from a cash crisis. For the millions of small business owners focused on growth, working capital discipline represents one of the highest-leverage improvements they can make.
