Improving working capital involves optimizing cash flow by accelerating receivables, tightening payables, and managing inventory more efficiently. Key strategies include digitizing invoicing, offering early payment discounts, negotiating longer supplier terms, and using forecasting tools to reduce excess stock. These actions can increase cash on hand, lower interest costs, and improve liquidity.

Cash is the lifeblood of any business. Without it, companies can’t grow, invest, or weather economic shifts. That’s why working capital optimization is now a top priority. 

For procurement leaders, working capital improvement is not a one-time project. It is a continuous discipline that touches every supplier relationship, every invoice, and every payment cycle. Organizations that treat it strategically, using platforms like Suplari's Payments Management solution, consistently outperform those relying on spreadsheets and manual processes.

This guide shows you how procurement can close the working capital gap with clear steps. You will also see where AI can automate the grind and keep savings from leaking.

Why this matters?

  • PwC counts €1.56 trillion of excess working capital worldwide—cash that could fund growth instead of gathering dust.
  • According to McKinsey businesses can cut the balance locked in payables and receivables by 30 percent or more when they launch a focused working-capital program.

Procurement’s role in working capital optimization

Procurement controls billions in supplier spending at most enterprises. Every payment term negotiated, every discount captured, and every invoice processed on time (or late) directly impacts working capital. Yet too many procurement teams still manage payments reactively.

Suplari changes this dynamic. By connecting spend data, contract terms, and payment behavior in a single platform, Suplari gives procurement leaders real-time visibility into where cash is trapped and how to free it. The Payments Management solution is purpose-built for this challenge, automating payment term optimization, discount capture, and cash flow forecasting so procurement can move from reactive to strategic.

The working capital optimization loop looks like this:

  1. Analyze current payment terms, discount utilization, and cash conversion cycle using Suplari Spend Analytics.
  2. Identify opportunities: term extensions, early payment discounts, duplicate payments, and rogue spending.
  3. Act with automated workflows through Suplari Payments Management.
  4. Monitor results in real time and adjust strategies continuously.

Working capital optimization in practice

Working capital optimization means using the timing and terms of supplier payments as a strategic lever. By stretching cash outflows wisely you lift liquidity while still nurturing supplier trust.

Think of it as a continuous improvement loop:

• Extend payment terms during contract talks—without bruising relationships.
• Capture early-payment discounts only when the return beats your cost of capital.
• Offer supplier-financing options that help partners and protect your cash.
• Tighten internal processes so invoices never leave early.

Working Capital Optimization In Procurement

1. Extend and optimize payment terms

Payment terms define when you pay your suppliers—net-30, net-45, or even net-90. While a few days might seem small, extending terms across millions in spend creates major liquidity gains. For example, shifting a $10 million supplier base from 30 to 60 days frees up the equivalent of one month’s spend—about $833,000 in working capital.

But smart extension doesn’t mean pushing every supplier to the limit. It’s about segmentation. High-risk or small suppliers may need faster payments to stay afloat. Meanwhile, large, well-capitalized vendors can often accept longer terms without issue—especially when the total value of your business with them is high.

A balanced strategy might look like this:

  • Tier 1 strategic suppliers: Net-45 to Net-60, with clear communication and optional financing.
  • Mid-tier operational suppliers: Net-60 as standard, aligned with industry benchmarks.
  • Tail spend suppliers: Net-90 if risk is low and volume is minimal.

AI-powered spend analytics can help. By pulling in supplier size, financial health, contract history, and payment behavior, smart systems can suggest which suppliers can safely be moved to longer terms - without damaging the relationship.

The key is transparency. Explain your payment policy, offer support, and ensure terms are realistic for each partner. That way, you protect your cash flow and keep your supplier base strong.

2. Capture high-return early payment discounts

Sometimes, paying early makes more financial sense than holding onto cash. Suppliers may offer discounts like “2/10 net-30,” meaning you get 2% off if you pay within 10 days. If your company’s cost of capital is lower than the discount’s implied return, it’s a smart trade.

Here’s the math: a 2% discount for paying 20 days early equals a 36% annualized return. That’s far better than what you’d earn holding the cash in a bank account - or even investing in many projects.

But here’s the catch: most companies don’t take full advantage. Why? Because applying discounts manually is slow, inconsistent, and error-prone. That’s where dynamic discounting tools come in. These systems:

  • Analyze every invoice in real time.
  • Compare the discount offer to your cost of capital.
  • Flag which payments to accelerate for maximum return.

With AI, this becomes even smarter. Machine learning models can learn from past transactions and predict which discounts are most likely to be accepted—and which suppliers might offer new ones if prompted.

Some suppliers may even prefer a discount over waiting 30 or 60 days. By automating the offer and acceptance process, you unlock more value without slowing down the AP team.

3. Improve payment process accuracy and timing

Even if you negotiate perfect terms, cash can leak due to poor execution. Many companies still overpay, pay too early, or miss discounts because their internal workflows are manual or disjointed.

To fix this, start by automating your invoice-to-pay process:

  • Use e-invoicing to capture data with fewer errors.
  • Set up approval workflows that route invoices by value, risk, or urgency.
  • Schedule batch payments to ensure money goes out exactly when it’s due—never early.

These steps prevent accidental prepayments, eliminate human error, and reduce friction between procurement, finance, and suppliers.

Advanced AI procurement tools can even monitor exceptions—like duplicate invoices or unusual payment patterns—and alert you before money leaves the system. Over time, this builds trust with suppliers and helps you meet terms consistently, which can unlock better deals.

The result? Your working capital program doesn’t just look good on paper—it delivers measurable results in the real world.

4. Use supplier financing to create win-win solutions

What if you could keep your payment terms long—but still help your suppliers get paid faster? That’s exactly what supplier financing, also known as reverse factoring, makes possible.

Here’s how it works:

  • You approve an invoice for payment.
  • A third-party finance provider pays the supplier early—often within days.
  • You then pay the finance provider later, on your original payment schedule.

This setup gives suppliers fast access to cash at a lower cost than they’d get on their own. Meanwhile, your company preserves liquidity and strengthens supplier relationships.

It’s a smart tool for managing risk too. Suppliers with tight cash flows are less likely to delay orders, cut quality, or break contracts if they have reliable access to working capital. With financing in place, your supply chain becomes more resilient.

To launch a program, focus on your most critical or cash-constrained partners. Make it optional, easy to join, and backed by clear communication.

5. Reduce cash traps in inventory and rogue spending

Working capital isn’t just in accounts payable—it’s also tied up in inventory and uncontrolled spend.

Excess inventory means cash sitting on shelves. To reduce that, consider:

  • Just-in-time (JIT) inventory practices that align ordering with actual demand.
  • Demand forecasting tools that predict needs using real-time data.
  • Economic order quantity (EOQ) models that calculate optimal batch sizes.

On the other hand, maverick spending—when employees buy off-contract—creates chaos. It leads to higher prices, inconsistent terms, and poor spend visibility. By tightening controls and consolidating suppliers, you reduce waste and negotiate better deals. That, in turn, improves both working capital and procurement efficiency.

6. How AI boosts results across the board

Modern procurement analytics software accelerate every part of this process with AI.

Solutions like Suplari can analyze supplier risk to guide payment term extensions. They identify when early payments deliver the best returns. They scan payment behavior to flag leaks. And they automate workflows so fewer decisions rely on manual effort.

AI also helps with real-time “what-if” scenarios. You can model how a 10-day term shift would affect liquidity. Or see the working capital impact of onboarding a new supplier financing program.

In short, AI takes the guesswork out—and puts data and speed in.

Commonly used metrics for working capital management

Tracking the right metrics is essential for measuring progress and identifying opportunities. Three metrics form the foundation of working capital management:

Current ratio

Formula: Current Assets / Current Liabilities

The current ratio measures your ability to pay short-term obligations. A healthy current ratio falls between 1.2 and 2.0. Below 1.2 signals potential liquidity risk. Above 2.0 may indicate excess idle assets that could be deployed more productively.

Cash conversion cycle (CCC)

Formula: Days Inventory Outstanding + Days Sales Outstanding - Days Payable Outstanding

The CCC measures the number of days it takes to convert inventory and receivables into cash, net of the time you take to pay suppliers. A shorter CCC means faster cash generation. World-class companies target negative CCCs, meaning they collect from customers before they pay suppliers.

Quick ratio (acid-test Ratio)

Formula: (Current Assets - Inventory) / Current Liabilities

The quick ratio is a more conservative measure of liquidity because it excludes inventory, which cannot always be converted to cash quickly. A quick ratio above 1.0 indicates the company can meet short-term obligations without relying on inventory liquidation.

Potential Benefits of Working Capital Improvement

The impact of systematic working capital optimization is substantial and well-documented:

  • Deloitte reports that organizations implementing comprehensive working capital programs achieve 10-30% improvement in working capital performance.
  • Cash liberation. Companies with EUR 500 million in annual spend can typically free EUR 25-75 million in cash through payment term optimization alone.
  • Cost reduction. Capturing early payment discounts at scale can generate 1-3% savings on addressable spend.
  • Improved credit metrics. Better working capital ratios lead to improved credit ratings and lower borrowing costs.
  • Supplier relationship strength. Counter-intuitively, structured programs like reverse factoring can improve supplier satisfaction by giving smaller suppliers faster access to cash.

Suplari customers consistently report measurable improvements across these dimensions. The combination of Spend Analytics, Payments Management, and Contract Intelligence provides the end-to-end visibility and automation needed to sustain gains over time, not just achieve them once.

How AI Boosts Working Capital Results Across the Board

The Hackett Group's 2026 data makes the case clearly: with technology spending up 6.1% but productivity lagging by 8.9%, the problem is not a lack of tools. It is a lack of intelligent tools. AI transforms working capital management from a periodic, labor-intensive exercise into a continuous, automated capability.

Suplari's AI engine delivers working capital improvement through:

  • Risk-adjusted term optimization. The platform evaluates supplier financial health, delivery performance, and market conditions to recommend payment term strategies that maximize cash benefit without creating supply chain risk.
  • Predictive discount optimization. Rather than applying a blanket discount policy, Suplari's AI calculates the optimal discount strategy for each supplier based on cost of capital, cash position, and supplier willingness.
  • Payment behavior scanning. The platform continuously monitors actual payment performance against terms, identifying drift and recommending corrections. If your team is consistently paying Supplier X 12 days early, Suplari surfaces that finding and quantifies the cash impact.
  • What-if scenario modeling. Procurement leaders can model complex scenarios: What is the working capital impact of extending all Tier 2 supplier terms by 15 days while increasing early payment discount capture by 20%? Suplari calculates the net effect across CCC, current ratio, and free cash flow in real time.
  • Anomaly detection. AI identifies duplicate payments, unusual payment patterns, and policy violations that drain working capital silently.

These capabilities are integrated into Suplari's Payments Management platform, making AI-driven working capital optimization accessible to procurement teams without requiring data science expertise.

Cash is king. Procurement can be the hero.

Working capital optimization is a strategic lever that supports growth, improves resilience, and delivers measurable ROI.

Procurement is the knight in shining armor. By managing payment terms, enabling discounts, improving processes, and applying the right technology, you can unlock trapped capital—without cutting budgets or damaging supplier trust.

Whether your goal is to fund new initiatives, boost your balance sheet, or simply weather uncertainty, working capital is where you start.

Start smart. Start with procurement.
