Here's a truth most mid-market companies ignore: you're sitting on a pile of cash you don't know you have.

Working capital optimisation isn't glamorous. It doesn't make headlines like fundraising or acquisitions. But for companies generating €250k-€25M in revenue, it's often the single highest-return opportunity available.

The Hidden Cash Opportunity

The Numbers Don't Lie

Most mid-market companies can release 10-25% of revenue through working capital optimisation. For a €5M revenue company, that's €500k-€1.25M in freed cash - without taking on debt or diluting equity.

In an environment where interest rates have risen from near-zero to 5%+, the cost of working capital has roughly tripled. Every euro tied up in operations now costs significantly more.

The Cash Conversion Cycle

Your cash conversion cycle measures how long money is trapped in your operations:

Days Inventory Outstanding (DIO) + Days Sales Outstanding (DSO) - Days Payable Outstanding (DPO) = Cash Conversion Cycle

Each component represents an optimisation opportunity:

DIO (Inventory): How long products sit before sale
DSO (Receivables): How long customers take to pay
DPO (Payables): How long you take to pay suppliers

Attacking Each Component

Inventory: Stop Hoarding Stock

Inventory often represents the largest working capital investment. Key levers:

ABC analysis - Classify inventory by value and movement. Focus management attention on high-value items consuming most capital.

Safety stock review - Most companies carry more safety stock than necessary. Review actual demand variability and lead time variability to right-size buffers.

Slow-moving stock discipline - Implement clear policies for ageing inventory. The stock that's been sitting for 12 months isn't going to magically sell.

Forecasting improvement - Better demand forecasting reduces both stockouts and overstock. Even modest accuracy improvements deliver significant working capital benefits.

Supplier lead time reduction - Shorter lead times enable lower safety stock. Work with suppliers on lead time compression or consider alternative suppliers.

Receivables: Get Paid Faster

Every day of DSO improvement releases cash. Practical approaches:

Invoice promptly and accurately - Delayed or disputed invoices extend payment. Automate invoicing and ensure accuracy.

Payment terms alignment - Review customer payment terms against actual payment patterns. Tighten terms where relationship and competitive position allow.

Collection process excellence - Systematic collection processes outperform ad-hoc chasing. Define clear escalation paths and follow them consistently.

Early payment incentives - Offer discounts for early payment where the cost is lower than your financing cost. In high-rate environments, early payment discounts become more attractive to customers.

Customer credit assessment - Prevent problems by assessing credit risk before extending terms. The cheapest working capital improvement is avoiding bad debt.

Payables: Optimise (Don't Abuse) Payment Timing

Payables extension can improve working capital but requires balance:

Negotiate terms strategically - Request extended terms during supplier negotiations. Larger suppliers often have lower financing costs and may accommodate reasonable requests.

Take early payment discounts - When suppliers offer 2%/10 net 30, the implied annual return for paying early is approximately 36%. If your cost of capital is lower, take the discount.

Avoid relationship damage - Stretching payments beyond agreed terms damages supplier relationships and may affect service levels. Optimise within terms, don't abuse them.

Consider supply chain finance - Programmes enabling supplier early payment at your financing rates can benefit both parties.

Technology That Makes It Work

ERP Systems

Modern ERP systems provide real-time working capital visibility and automated workflows for purchases and payments. If you're not using your ERP's cash management capabilities, you're leaving money on the table.

Specialised Tools

Cash flow forecasting software - Sophisticated projection capabilities beyond basic ERP functionality
Supply chain finance platforms - Dynamic discounting and supply chain finance programmes
Receivables management - A/R automation improving collection effectiveness

Building Organisational Capability

Cross-Functional Collaboration

Sales-finance alignment - Ensure sales teams understand working capital impact of payment terms
Operations-finance partnership - Collaborate on inventory optimisation balancing operational needs with efficiency
Procurement discipline - Clear processes preventing uncontrolled working capital growth

Performance Metrics

Working capital dashboards - Executive visibility into key metrics with trend analysis
Team accountability - Clear ownership for DIO, DSO, and DPO targets
Incentive alignment - Consider incorporating working capital metrics into management incentives

Your Implementation Roadmap

Phase 1: Assessment (4-6 weeks)

Analyse current working capital position and cash conversion cycle
Benchmark against industry standards
Identify quick wins and strategic opportunities

Phase 2: Quick Wins (2-3 months)

Implement collections improvements
Rationalise slow-moving inventory
Optimise payment timing within existing terms

Phase 3: Strategic Initiatives (6-12 months)

Implement technology solutions
Establish supply chain finance programmes
Restructure payment terms with key partners

Phase 4: Continuous Improvement (Ongoing)

Regular working capital reviews
Ongoing process refinement
Capability building and team development

Measuring Success

Cash flow impact - Track actual cash released. Target €50k-€1M+ for most mid-market companies.

Cycle time reduction - Measure cash conversion cycle improvement. Target 10-20% reduction over 12 months.

Cost savings - Calculate avoided interest expense and improved discount capture. Typically 1-3% of revenue annually.

Growth enablement - Assess how improved working capital supports growth investments.

The International Dimension

Working capital optimisation becomes more complex - and more valuable - for international operations:

Currency management - Holding receivables in depreciating currencies or payables in appreciating currencies destroys value. Align currency strategy with working capital goals.

Cross-border payment efficiency - International payments often suffer from delays and fees. Optimise banking and payment routes.

Letter of credit management - Trade finance instruments affect working capital timing. Optimise LC terms and documentation.

Supplier relationship building - Particularly in Asian markets, payment reliability strongly influences supplier relationship quality and pricing.

The Bottom Line

Working capital optimisation represents one of the highest-return opportunities for mid-market companies. Unlike external financing, it requires no dilution or debt increase - just better management of existing resources.

Companies that systematically optimise working capital typically free up capital equal to 15-30% of revenue, creating flexibility for growth investment, debt reduction, or shareholder returns.

The cash is already there. You just need to unlock it.
