From Cash Drain to Cash Engine: SME Working Capital Tactics
A historic building framed by a modern tower, with US and California flags on the roof, symbolises financial foundation and strategic transition. The image highlights how disciplined working capital preserves core strengths while enabling modern growth, and how strong liquidity builds credibility with suppliers, lenders, and customers.
Cash flow and liquidity are the lifeblood of SME success. In this third instalment of our series on cash and liquidity management, we show how SME owners and entrepreneurs can treat cash and liquidity as strategic levers to build competitive advantage and scale their businesses. We also share practical, actionable practices to help SMEs avoid running out of cash — a leading cause of business failure Read last week’s SME Cash Flow Excellence.
This week we focus on working capital, citing McKinsey — Make Working Capital Work Harder for You and Accounting tools.com How to Manage Working Capital
3 Working capital consists of three accounts: accounts payable, accounts receivable, and inventory. Left unmanaged, these accounts can tie up significant cash. Receivables can generate cash; inventory and payables typically consume it.
When a business requires excessive working capital, it risks exhausting available cash and failing to meet obligations to suppliers, staff, or lenders. Managed correctly, working capital releases cash to fund investment and growth and increases enterprise value.
Cash Flow and Working Capital Blueprint for SME Owners
Working Capital Mastery for SMEs: Policies, KPIs, Blueprint
This blueprint explores best practices for optimising working capital to harvest a source of low hanging fruit, create competitive advantage and build a more resilient, successful business.
1. Implement a working capital policy
Create and enforce a working capital policy with daily and weekly checks. Train and educate the staff who manage these accounts so they understand the importance of cash not tied up in working capital and the risks if it is. The goal is a mindset shift supported by performance targets and KPIs — for example, cash conversion cycle days linked to overall cash flow improvements. Communicate the policy and the reasons behind it across the business.
SME Takeaway:
Make the policy operational: tie it to incentives, celebrate KPI wins, and communicate the business results. Hold everyone accountable — from management to staff — so the organisation values cash and recognises that future growth depends on it.
2. Adopt best practices for managing working capital accounts
Ensure customers and suppliers are billed and paid optimally. Manage payables to maximise credit terms — an interest‑free loan to the business 3— and use this free working capital wisely to fund growth. Receivables require proactive collections and credit checks: extend credit only to customers who can pay.
Also manage gross margin in connection with receivables. If margins are low, avoid offering long credit terms because that increases the need for working capital while waiting for customer payments.
SME Takeaway:
Treat payables as a funding asset and negotiate better credit terms. Prioritise timely collections and creditworthiness. Align margin strategy with credit policy to avoid creating unnecessary working capital strain.
3. Implement working capital planning systems and tools
Use inventory systems, digital analytics, and AI to optimise inventory and cash positions. Inventory often kills cash faster than receivables because it can pile up when demand drops or products become obsolete, forcing discounting to generate cash3.
SME Takeaway:
Connect inventory systems with suppliers to enable just‑in‑time processes. Use AI to design invoice collection strategies. Track inventory strictly and convert it to cash promptly. Implement planning systems to control purchasing and usage. For example, the founder featured in our FLIGHT 78910 SME Spotlight tracked every item in Excel early on because the business was inventory‑heavy and needed tight control to gain traction.
4. Business planning alignment with working capital
Every decision to increase sales, scale, or enter new markets affects working capital and can threaten the business if not understood.
SME Takeaway:
Business plans must consider gross margins, market expansion, credit‑term changes, and declining sales — all of which affect working capital. Ensure the right amount of working capital is available for each decision. High gross margins can support rapid growth; low margins can bankrupt a business. Avoid masking working capital needs with excessive debt, since interest costs will erode residual cash3.

Julie Wainwright The RealReal
WATCH Video Feature: She Built a $1 Billion Brand Selling Other People’s Clothes
Industry focus Introduction
Julie Wainwright built The RealReal, a luxury resale fashion brand, scaling it to $1 billion in sales and taking it public on Nasdaq by applying strategic, operational, and financial discipline. She combined deep customer insight with rigorous business management: matching demand and supply, balancing fixed and variable costs, and continuously reconciling the income statement, balance sheet, and cash flow — with special attention to cash and working capital.
Her success came from understanding the what, why, when, who, and how of cash and working capital needs, and from managing both with excellence.
Highlights for SME Business Owners
1. Business Plan Aligned with Working Capital
The RealReal is capital intensive. From launch, Julie scaled operations — warehouses, people, and product flow — in line with the capital required at each stage. She implemented an optimal pricing and sell‑through strategy so that roughly 90% of products sold within 90 days, keeping inventory moving and avoiding the need for larger warehouses and the extra working capital they would require.
She kept capital expenditure tightly controlled and used business planning to manage the supply chain proactively. When California became detrimental to her supply chain goals, she relocated operations to Arizona to protect performance.
SME Takeaway:
Plan capacity and capital together. Use sell‑through targets and pricing to avoid tying up cash in excess inventory. Pre‑plan supply chain and location decisions to reduce working capital strain.
2. Working Capital and Inventory Management
Early on, Julie tracked inventory in Excel before moving to more sophisticated systems. That discipline enabled the 90‑day sell‑through and demonstrated that scaling requires clear, principle‑based stock level targets and strict inventory processes..
SME Takeaway:
Establish basic stock level targets and inventory controls before scaling. Simple systems, used consistently, can prevent cash drain and keep the business solvent while it grows.
3. Operational and Financial Discipline
Julie used staged financing: seed capital to reach initial milestones, then venture capital to scale further, and ultimately an IPO. Each growth step was aligned with working capital needs and timing.
SME Takeaway:
Align funding strategy with working capital requirements. Marketing or sales campaigns that drive volume will increase warehouse throughput, staffing needs, and potentially new facilities — all of which require working capital. Plan for these cash needs in advance.

Strategic Takeaway
To avoid running out of money and to build a competitive moat, every SME owner must adopt a financial management policy that explicitly includes a working capital policy. This policy should force day‑to‑day operational decisions to align with long‑term growth objectives.
Embed the policy in onboarding for finance, sales, procurement, and warehouse teams (where relevant) so everyone understands that cash and liquidity come before EBITDA. Reinforce the message through regular training and internal communications, and share concrete wins from applying the policy to build momentum and accountability. Over time this creates a culture of cash excellence that protects the business today and enables future growth.
Define clear metrics and KPIs for cash performance and tie them to incentives to change behaviour. For example, structure sales incentives around timely cash outcomes rather than just revenue: discourage indiscriminate credit extension and reward deals that deliver prompt payments or include appropriate early/late payment terms. That alignment ensures the sales team brings in profitable, cash‑positive business.
Conclusion
To avoid running out of money and to build a competitive moat, every SME owner must establish a financial management policy that includes a working capital policy. This policy should be part of onboarding for finance, sales, procurement, and warehouse staff so everyone understands that cash and liquidity are priorities — not just EBITDA.
Introduce a culture of cash excellence with regular communication, incentives, data, and targets so working capital performance is tracked and celebrated. Set metrics and KPIs to measure cash performance and integrate incentives to align behaviour. For example, tie sales incentives not only to revenue but to timely payments so the sales team brings in business that generates timely cash flow.
Working capital is essential for any small and medium‑sized business. Improving its performance can generate cash to fund value‑creating opportunities and reveal insights that improve other aspects of business performance [1]. Working capital can be a source of low hanging fruit. This employed wisely, working capital becomes a strategic competitive asset.
