Working Capital Subsidy
How growth-stage companies become interest-free lenders to their enterprise customers.
Composite case. Details have been altered to preserve privacy while retaining the structural pattern.
His revenue grew 38 percent last year, and his cash conversion cycle stretched from 45 to 72 days. The growth made the company worse off, and the board deck did not show it.
The CFO handed me his March deck on a Tuesday. Revenue up 38. Gross margin holding at 74. EBITDA expanding. Every slide told the story of a company accelerating.
Then we turned to the balance sheet. Accounts receivable had grown from $3.2M to $5.8M in twelve months. The cash conversion cycle had stretched 27 days. At his revenue run-rate, 27 additional days of working-capital drag meant something close to $3.4M of cash trapped in receivables that had not been there twelve months earlier.
He did not know the number. His controller tracked receivables. His VP of Sales tracked bookings. Nobody tracked the gap between the two, and the gap was quietly consuming the runway his growth was supposed to be building.
The reason this matters now, in 2026, is that the cost of carrying that gap has risen and the timing of paying for it has tightened. The current rate environment makes working capital expensive in a way it was not in the 2010s. AI-extended enterprise sales cycles are pushing implementation timelines from 90 days toward 120 to 150. PE secondary diligence has learned to reverse-engineer CCC from public comp data, which means the buyer in 2026 already knows the number before the seller does. The 2025-vintage funds entering their exit windows are running into the same bid-ask gap on mid-market software that opened around obligation stacks last year, with cash conversion cycle as the new line item being adjusted.
I have run this audit on roughly forty portfolio companies in the last decade. The CCC trajectory has been stretching in thirty-six of them. The two companies where the metric improved over the hold period were the ones whose CFOs had the number on a single dashboard before I asked for it. The argument I make in this essay is not academic. It is the audit the operator should run before the secondary buyer does.
This happens when working capital gets treated as an accounting output instead of an operating decision.
Working capital subsidy
Every dollar sitting in receivables is a dollar the company has earned but cannot spend. Every dollar of payables is borrowed time from a future obligation. The spread between the two determines how much of your revenue actually converts to deployable cash, and in most growth-stage companies that conversion rate is deteriorating quarter over quarter while the P&L looks better and better.
The deterioration follows a predictable pattern as companies move upmarket. An SMB customer pays by credit card on a monthly subscription: cash on day one. An enterprise customer pays on net-60 terms after a 90-day implementation: cash on day 150. A company that shifts 30 percent of its revenue from SMB to enterprise without adjusting its cash model is not selling a product anymore. It is extending interest-free financing to its customers, secured by nothing but the assumption they will pay on time.
The inverse case is the cleanest illustration of how much the cycle matters. Through the 1990s, Dell Computer ran a negative cash conversion cycle. Customers paid by credit card on day zero. Suppliers were paid on net-30. The float between the two was the structural engine of Dell’s growth, and it was the variable that distinguished Dell from every other PC manufacturer in the same product category. The product was commodity. The cash cycle was the moat. Most of the growth-stage software companies operating in 2026 run the inverse of Dell, extending the float to customers rather than collecting it from them, and most of their CFOs cannot tell you which direction the company is moving on that variable quarter over quarter.
Vendr’s Q4 2024 SaaS Buyer’s Almanac reports that average enterprise SaaS payment terms have stretched 11 days since 2022 across the mid-market portfolio. The shift is industry-wide and accelerating.
Meanwhile the company’s own obligations are growing on the opposite clock. Each enterprise deal requires implementation staff, compliance upgrades, and dedicated support. Costs hit the bank account on day one. The customer’s payment arrives five months later. The difference is funded by the company’s cash balance, and nobody calls it what it is. Working capital subsidy.
The incentive structure guarantees deterioration
The operators who manage this well negotiate payment terms with the same intensity they negotiate contract value. A $500K deal with net-90 terms is not the same deal at $480K with net-30. At a 10 percent cost of capital, the faster-paying deal is more valuable. But most sales compensation plans reward contract value and ignore collection speed. The incentive structure guarantees that cash conversion will deteriorate as the sales team succeeds.
This is the same shape as the obligation stack problem. The cost gets distributed across cost centers and nobody owns the aggregate. The CFO sees receivables grow. The CRO sees deal sizes grow. The CEO sees revenue grow. None of them sees the gap between the bookings curve and the cash curve until the gap is wide enough to require a working capital line of credit, at which point the discussion is no longer strategic. It is defensive.
The objection that deserves a fair hearing
The strongest counter-argument is real. Net-60 enterprise payment terms are the price of admission to enterprise revenue. You cannot demand net-30 from a Fortune 500 procurement organization. The CCC deterioration is the rational cost of moving upmarket, and it is worth paying because enterprise customers retain at 95-plus percent and produce two-to-three times the LTV of SMB. Refusing the subsidy is refusing the segment.
The objection is partly right and underweights the inflection point. Some working capital subsidy is the rational cost of moving upmarket. The right size is the size that grows in proportion to revenue, not faster. The subsidy stops being rational when CCC growth outpaces revenue growth, when the working capital line of credit becomes structural rather than seasonal, or when the gap between booking and cash conversion exceeds the duration of the next equity round. At those inflection points the subsidy is no longer financing growth. It is being financed by future dilution that the cap table will pay for at exit.
The discipline that distinguishes durable scaling from drift is asymmetric. You absorb working capital subsidy aggressively when the customer cohort genuinely justifies it. You insist on payment-term discipline everywhere else. The companies that compound through cycle measure the subsidy as a discrete line item and require an explicit case for each enterprise customer cohort that produces it. Most growth-stage companies do not measure it at all.
Three questions, asked monthly
The fix is to treat working capital as a strategic variable discussed at the same altitude as revenue growth and margin expansion. Three principles, applied in order, surface the trapped cash before it accumulates.
Measure the cycle, not just the components. Your CFO should be able to tell you CCC this quarter versus last in a single number. If it is moving in the wrong direction, the explanation lives in one of three places: customer mix, payment terms, or collections discipline. Pick one and own it. If the number takes more than an hour to produce, you do not have a cash conversion metric. You have receivables and payables in two separate dashboards.
Price the growth. If revenue doubles, how much additional working capital does the growth consume? The answer is rarely zero. It is usually 20 to 40 percent of incremental revenue in companies moving upmarket. That figure is the working capital subsidy rate, and it should appear in every revenue plan presented to the board.
Locate the accountability. Where in the org chart does collection speed get measured? If the answer is finance, then sales is not accountable for the cash they generate. The fix is to put a CCC metric in the sales comp plan, even at 5 percent weight. The behavior changes inside one quarter, and the change shows up in the cash flow statement before it shows up in the P&L.
The predictive claim
By mid-2027, the spread between PE-backed software companies that have actively reduced CCC over the prior eight quarters and those that have let it expand will be the single largest determinant of exit-multiple compression, exceeding ARR growth rate for the first time in this cycle. The shift will be visible in diligence question patterns this year. The question that takes the place of “what is your net retention?” in 2027 will be “what is your CCC trajectory over the last eight quarters?”
This is testable. By Q4 2027, the operating-multiple dispersion across mid-market PE software exits will sort more cleanly by CCC trajectory than by either revenue growth or gross margin. The companies that exit at premium multiples will be the ones whose CFOs can produce a CCC-trajectory chart by quarter without a research project. The companies that exit at discounts will be the ones whose CCC expanded over the hold and whose CFOs did not know it was happening until diligence flagged it.
The closing
The P&L is where growth is recorded. The cash conversion cycle is where it is paid for. Most boards see the first and not the second. Most CFOs report the first and not the second. Most CEOs are measured on the first and not the second.
Dell ran the inverse and made the cash cycle the engine of its growth. Most growth-stage companies run the inverse of Dell and do not know they are doing it. The gap between those two postures is the variable that determines whether the company is generating cash at exit or borrowing from a future round to fund the appearance of generating it.
Run the math from this essay against your last twelve months. Revenue times CCC delta divided by 365. The number will surprise you. The Structural Audit produces it in eight minutes against your actual revenue base.
The board deck does not show it. The cash flow statement will.
