Improving Working Capital Requirement (WCR) is one of the most effective ways to release cash without borrowing more money or increasing sales. But reducing WCR is not simply a financial exercise: it means improving the processes that generate customer receivables, inventories and supplier payables.
Only a minority of businesses collect from customers before paying suppliers and other operating expenses. Most must finance the gap. The objective is therefore to reduce cash tied up in the operating cycle without weakening customer relationships, supply reliability or profitability.
The three levers for improving working capital
1. Reduce receivables
Shorten the time between delivery and payment, prevent disputes and collect invoices more effectively.
2. Optimise inventories
Reduce unnecessary stock and production cycle time without compromising service levels.
3. Manage supplier payables
Negotiate sustainable terms and improve purchasing processes while respecting contractual and legal obligations.
These levers must be managed together. For example, extending supplier terms while creating supply disruptions may ultimately increase inventories, delay sales and worsen WCR.
Prerequisites for a successful WCR action plan
Working capital improvement is a cross-functional project. It challenges established practices and can generate resistance, especially when commercial, operational and financial objectives are not aligned.
- Secure senior management commitment. Explain how reducing WCR improves liquidity, financing costs and the capacity to invest.
- Diagnose the operating cycle. Analyse customer segments, inventory categories, supplier terms and the processes responsible for delays.
- Prioritise by cash impact and feasibility. Estimate potential gains, implementation costs and risks before launching initiatives.
- Assign owners and deadlines. Finance coordinates the programme, but sales, operations, purchasing and customer service implement most actions.
- Train and engage teams. Employees need to understand why their decisions affect cash flow.
- Measure realised results. Monitor cash released, DSO, inventory days, DPO, overdue balances and service quality.
First lever: reduce accounts receivable
Accounts receivable can be improved long before an invoice becomes overdue. The most effective actions often address contractual, administrative and commercial causes of late payment.
| Action | Why it works | Who is involved? |
|---|---|---|
| Negotiate appropriate payment terms | Reduce contractual payment periods where commercially and legally appropriate; assess their impact before agreeing to exceptions. | Sales, credit management |
| Request down payments | Finance part of the order or project before incurring the full operating costs. | Sales, project management, finance |
| Invoice promptly and accurately | Avoid delays between delivery and invoicing, and prevent disputes caused by missing references or incorrect documents. | Billing, operations, customer service |
| Define clear contractual terms | Clarify due dates, acceptance conditions, payment methods and dispute procedures. | Sales, legal, credit management |
| Resolve disputes quickly | Remove genuine obstacles to payment through coordinated action across departments. | Sales, customer service, operations |
| Prioritise cash collection | Focus on the most relevant customers, invoices and causes of non-payment instead of sending indiscriminate reminders. | Credit management |
| Align commercial incentives | Include payment quality, overdue exposure or cash collected in performance discussions where appropriate. | Management, sales, finance |
Receivables financing, such as factoring or invoice discounting, can accelerate access to cash. However, it does not automatically improve the underlying customer payment process. Its fees, recourse provisions and accounting treatment must be considered separately from operational WCR improvements.
The objective is not to increase the number of collection reminders. It is to eliminate avoidable delays and take the actions most likely to result in payment, while preserving a constructive customer relationship.
Second lever: reduce inventories without undermining operations
Inventory reduction is closely linked to supply-chain performance. Raw materials, work in progress and finished goods must be analysed separately because their drivers differ.
- Improve demand forecasting: align purchasing and production with realistic sales forecasts.
- Monitor inventory in real time: maintain reliable physical and system records, with regular counts and clear ownership.
- Identify slow-moving and obsolete stock: establish plans to sell, reuse or responsibly dispose of items that immobilise cash.
- Shorten lead times: work with suppliers and production teams to reduce unnecessary waiting periods.
- Improve inventory rotation: review reorder points, batch sizes, safety stock and product segmentation.
- Reduce work in progress: address production bottlenecks and long internal processing cycles.
Lean and just-in-time approaches can reduce WCR, but excessively low stocks can create stockouts, emergency purchasing and dissatisfied customers. The right inventory level depends on demand variability, supplier reliability and the cost of service failures.
Third lever: manage supplier payables responsibly
Trade payables finance part of the operating cycle. Negotiated supplier terms can help align cash outflows with customer collections, but the objective should never be to make suppliers finance the business through systematic late payment.
- Negotiate payment terms as part of the overall purchasing agreement, within applicable legal limits.
- Consolidate purchases where appropriate to improve negotiating power and process efficiency.
- Improve invoice approval and payment scheduling to avoid both premature and overdue payments.
- Consider whether outsourcing non-core activities changes the timing of cash flows, while assessing total costs and operational dependence.
- Evaluate supply-chain finance or reverse factoring where commercially justified, including its costs and potential implications for suppliers.
Paying suppliers after the agreed due date is not a sound WCR strategy. It can trigger penalties, supply restrictions, loss of trust and legal consequences. Payment-term rules differ by jurisdiction; for example, France imposes statutory limits and exceptions under its commercial-law framework.
How much cash can these improvements release?
The cash effect of reducing receivables, inventories or extending agreed supplier terms depends on the relevant daily flow. The following scenarios are independent and illustrative.
| Action | Assumption | Illustrative cash effect |
|---|---|---|
| Reduce DSO by 5 days | Daily credit sales of €100,000 on a consistent receivables basis | €500,000 released |
| Reduce inventory holding by 5 days | Daily relevant inventory cost flow of €60,000 | €300,000 released |
| Increase negotiated DPO by 5 days | Daily relevant purchases of €50,000 | €250,000 of additional supplier financing |
These are simplified calculations, not guaranteed outcomes. A detailed forecast must consider VAT, changes in sales and purchase mix, seasonality, accounting conventions, payment schedules and any additional costs. Supplier payment terms must remain contractually and legally compliant.
Prioritise initiatives with a practical action matrix
| Initiative | Cash potential | Implementation effort | Priority |
|---|---|---|---|
| Eliminate delays between delivery and invoicing | Often high | Low to medium | Early action |
| Resolve recurring customer disputes | High where disputes are material | Medium | Early action |
| Review slow-moving inventories | Depends on stock profile | Medium | Targeted programme |
| Renegotiate supplier terms | Depends on purchasing base | Medium to high | Selective negotiation |
| Redesign production or procurement cycles | Potentially substantial | High | Structural programme |
Each initiative should have an accountable owner, a baseline, a target, a deadline and a method for verifying the actual cash released. The qualitative effects on service, customer satisfaction and supplier relationships also matter.
Digital credit management and AI: improve processes, not just activity volumes
Connected ERP, CRM, invoicing and credit management systems can identify unpaid invoices, disputes, customer risk and collection actions in one place. They make it easier to prevent avoidable delays and coordinate finance, sales and customer service.
AI can assist with interpreting customer messages, identifying payment patterns, prioritising actions and supporting cash forecasts. Its contribution depends on business expertise, interconnection of data, functional software quality and appropriate AI capabilities. Automation without relevant context may simply generate more activity without improving cash flow.

Beyond cash: better processes and customer satisfaction
A well-executed WCR programme can produce benefits beyond the immediate release of cash. Accurate invoices reduce disputes. Better coordination shortens resolution times. More reliable inventory management improves delivery performance. Clear supplier agreements reduce operational friction.
That is why improving WCR is not only a financial objective: it is also an opportunity to make the business more efficient and improve customer satisfaction.
