Working Capital Optimization — CFO Techniques Revealed

Cash feels tighter than the forecast says, boards are pushing for growth while operations push back, and one surprise receivable or elongated supplier term can blow a quarter. Working capital optimization is the lever most finance teams underuse — but it directly buys time, optionality, and credibility. If this sounds familiar, you’re not alone — and it’s fixable with the right structure.

Summary: A disciplined working capital optimization program—built from tighter AR, smarter payables, disciplined forecasting, and simple operational controls—turns trapped balance-sheet value into predictable runway. Apply the framework below and you can materially improve cash conversion, shorten FP&A cycles, and make better trade-off decisions between growth and liquidity.

What’s really going on? — Working capital optimization

On the surface, working capital problems look like “we don’t have enough cash.” Under the surface they’re process, commercial, and forecasting failures that compound: billing friction, inconsistent collections, unmanaged payment terms, and models that don’t drive action. Most mid-market companies treat working capital as an accounting outcome, not a repeatable operating discipline.

• Symptoms: recurring last-minute cash calls or bridge loans before payroll or vendor payments.
• Symptoms: growing DSO or aging receivables without a clear action plan.
• Symptoms: unpredictable monthly close and reconciliations that eat FP&A time.
• Symptoms: inconsistent supplier terms and missed opportunities for discounts or supply financing.
• Symptoms: forecasting that treats cash as a residual, not a KPI.

Where leaders go wrong

Common mistakes are understandable: finance teams are stretched, commercial teams own relationships, and operations treat cash as a byproduct. That combination creates blind spots.

• Relying on historical averages rather than rolling, cash-based forecasts — which hides turning points.
• Letting sales discount without finance approval or a measurable ROI for faster payment.
• Treating AR collections as a low-priority admin task rather than a revenue-protecting activity.
• Waiting for a “perfect” ERP cleanup before making process changes — paralysis by perfection.

Cost of waiting: every quarter you delay, you tighten runway and reduce strategic optionality—what could be a strategic hire or product investment becomes a short-term financing decision.

A better FP&A approach — Working capital optimization

Shift from reactive to structured: treat working capital as a controllable KPI, owned jointly by finance and commercial leaders, and managed through clear cadence and incentives. Below is a concise framework Finstory uses with clients.

1. Measure the right things (what): Move beyond net working capital to daily cash flow metrics—DSO (days sales outstanding), DPO (days payable outstanding), and a cash conversion cycle measured weekly. Why it matters: you can only manage what you measure. How to start: run a 13-week cash summary and weekly AR aging dashboard for the next 90 days.
2. Fix the near-term leaks (why): Tackle billing cadence, invoice accuracy, and collections scripts. Why it matters: small fixes compound. How to start: prioritize the top 20% of invoices by value or days late; assign owners and a 14-day contact cadence.
3. Negotiate smarter supplier and customer terms (what & how): Create a simple governance: finance approves exceptions, and fast-pay discounts get resale tracking. Why it matters: terms are negotiable levers for cash. How to start: profile top suppliers and customers by spend and cash impact and run targeted renegotiations for the top quintile.
4. Embed cash into commercial behavior (how): Introduce payment-linked incentives or milestone billing for services and SaaS usage thresholds. Why it matters: aligns sales with liquidity. How to start: pilot milestone billing on one product line or major customer segment.
5. Operationalize through cadence and tech (how): Weekly cash reviews, AR dispute dashboards, and one source of truth for receivables. Why it matters: cadence converts analysis into action. How to start: set a 30/60/90-day playbook for collections, assign SLAs, and stand up a single AR aging report shared with commercial leads.

Proof point: a mid-market B2B services client reduced DSO by double-digit days within two quarters after implementing this framework, releasing working capital equal to multiple percentage points of revenue and reducing reliance on short-term debt.

Quick implementation checklist

• Run a 13-week cash forecast and weekly AR aging this week.
• Identify top 20% of outstanding invoices (by cash value) and assign collection owners.
• Audit billing cadence and correct 3 recurring invoice errors that delay payment.
• Set standard payment terms and an exception governance for discounts.
• Pilot milestone or usage billing on a single product or customer cohort.
• Establish a weekly cash review: CFO, head of sales, controller, and head of ops.
• Map 3 supplier contracts to negotiate extended DPO or early-pay discounts.
• Create one AR aging dashboard and a one-page cash KPI scorecard for the board pack.
• Design a collections script and train the team; run two-week sprints to eliminate disputes.

What success looks like

• Improved forecast accuracy: rolling cash forecasts within a 5–10% variance vs. prior 20–30% swings.
• Shorter cycle times: cut month-end close and cash recon work by 20–40%, freeing FP&A for analysis.
• Faster AR: DSO shortened by double-digit days for many clients, converting receivables into actionable runway.
• Stronger board conversations: a single cash scorecard replaces ad hoc updates and builds credibility.
• Operational leverage: fewer fire drills and a predictable cadence for investment decisions.

Risks & how to manage them

• Data quality: Risk — poor ERP/ledger data undermines forecasts. Mitigation — run a focused month of reconciliations and a lightweight data-clean sprint limited to the top 10 account buckets before remodeling.
• Adoption: Risk — sales or operations resist stricter terms. Mitigation — tie pilots to clear incentives, use a one-quarter pilot, and report impact in commercial KPIs (conversion, churn, cash collected).
• Bandwidth: Risk — finance is already overloaded. Mitigation — prioritize high-impact, low-effort changes first (top invoices, billing fixes, weekly cadence) and consider external help for the initial uplift.

Tools, data, and operating rhythm

Tools matter, but only as enablers. The practical stack is simple: a reliable ledger/ERP, an AR aging and dispute log, a 13-week cash model (even in a spreadsheet), and a BI dashboard for weekly cash KPIs. The operating rhythm is more important: short weekly cash reviews, a monthly working capital deep-dive, and a quarterly strategic review with commercial leaders.

We’ve seen teams cut fire-drill reporting by half once the right cadence is in place.

FAQs

• How long before we see results? Quick wins (billing fixes, collections scripts) can move cash in 30–60 days; structural improvements (terms renegotiation, billing model changes) typically take 2–3 quarters.
• Do we need external help? Many teams implement quick wins internally, but an experienced FP&A partner accelerates prioritization, runs the initial cadence, and transfers operational practices to your team.
• How much effort is required? Initial lift is front-loaded: a focused 30–60 day sprint followed by lighter weekly maintenance—think concentrated effort for 4–6 weeks, then cadence ownership shifts to process owners.
• What’s the first place to start? Run a 13-week cash view and fix the top billing/AR issues identified by the aging report.

Next steps

If you’re a CFO or head of finance ready to make working capital a predictable lever rather than a surprise, start with a 30–60 day diagnostic: we map cash leaks, prioritize fixes, and quantify runway improvement. Working capital optimization is a high-return operational program—get a plan, run a focused sprint, and embed the cadence so improvements compound. The sooner you act, the sooner you convert balance-sheet friction into growth optionality.
