If your CFO hasn’t already put working capital optimization near the top of the priority list, chances are they’re about to.
This isn’t a new concept. Finance leaders have always cared about cash flow. But the conversation has shifted. It’s no longer just about collecting receivables faster or managing inventory tighter. Increasingly, the focus is on spend — specifically, how companies pay their suppliers and whether the payment terms they’re paying on are actually the best they can get.
The opportunity is real. And it’s often bigger than people expect.
1. Every Day Your Cash Leaves Early Costs More Than It Used To
When interest rates were low, paying a supplier a few days early was easy to overlook. With rates where they are today, math has changed. Every dollar sitting in a supplier’s account instead of yours carries a real and measurable cost of capital. Multiply across hundreds or thousands of suppliers, and the trapped cash in payment timing becomes one of the most expensive inefficiencies on the balance sheet. Finance leaders are recognizing that optimizing when they pay — not just what they pay — is one of the cleanest ways to put cash back on the books.
Add tariff volatility, inflationary pressure, and supply chain disruption, and the case gets sharper. Cash on hand isn’t just a preference — it’s a strategic buffer. Working Capital Acceleration through smarter payment terms frees up cash without cutting headcount, canceling projects, or squeezing supplier relationships. It’s additive, not reductive. And in an economy where the next disruption could come from anywhere, that flexibility matters.
2. The Biggest Line Item on the P&L Has the Biggest Optimization Gap
On average, 75% of Fortune 500 companies’ costs go toward external suppliers. It’s the single largest area of spend in most organizations — and even modest improvements have outsized impact on your bottom line. A 10% reduction in supplier costs can generate a 32% surge in EBITDA. Payment optimization is one of the most direct paths to get there.
Yet while procurement teams put enormous effort into negotiating pricing, the timing of supplier payments often gets far less attention. That’s a massive untapped lever. A few days’ difference with one major supplier can mean millions annually, but most companies don’t have the visibility to know it. Across a portfolio of suppliers, the numbers compound quickly.
3. Your Competitors Are Turning DPO Into a Strategic Advantage
This isn’t just about catching up. It’s about competitive separation.
The gap in payment performance between top-performing companies and everyone else is growing. The Hackett Group found a 9% DPO performance gap between top-quartile companies and the median and that gap is widening, not shrinking.
Organizations that have invested in visibility, benchmarking, and proactive management of their days payable outstanding (DPO) are operating with meaningfully more cash at their disposal than peers who haven’t.
That cash advantage compounds. It funds R&D. It supports operations. It reduces borrowing at today’s elevated rates. It creates room to invest in growth while competitors tighten belts. The longer a company waits to optimize, the wider that gap becomes.
4. It Delivers Measurable ROI in Weeks With No Disruption
This is the reason that surprises most people.
Working Capital Acceleration through payment term optimization doesn’t require a massive transformation, a new ERP, or a year-long implementation. It’s a data exercise — one that starts with information most companies already have at their fingertips and can pull together in under 20 minutes.
The cash impact is immediate and ongoing. Once better terms are in place, every single payment cycle reflects the improvement. Unlike cost-cutting measures that require sustained effort to maintain, optimized payment terms keep working automatically once they’re set, with the proper oversight.
For a CFO looking at a list of initiatives competing for attention and resources, a program that delivers measurable ROI in weeks with minimal operational disruption is hard to beat.
Why Most Companies Haven’t Fully Captured Working Capital Wins
If the opportunity is this clear, why hasn’t every company already acted on it? The answer isn’t a lack of awareness. It’s a combination of bandwidth, complexity, and a visibility gap that’s nearly impossible to close internally. In most organizations, three things are working against progress — not because teams aren’t capable, but because the problem cuts across functions and the data needed to solve it doesn’t live in any one place.
AP Teams Are Managing Enormous Volume
Many businesses juggle thousands of vendor relationships, with AP professionals handling thousands of invoices per FTE annually across multiple ERPs, payment systems, and P-cards. The focus is on paying accurately and on time. And most teams are doing exactly that. But “on time” and “optimized” are two different things. Paying a few days early doesn’t get flagged. Nobody raises it. It just quietly adds up. Organizations with AP Recovery programs are already looking at their payment data to reclaim overspend — Working Capital Acceleration is the natural next step.
Procurement Teams Need Data They Don’t Have
A typical large company maintains tens of thousands of active contracts. Renegotiations happen on set cycles, some contracts auto-renew, and procurement teams are often preparing for the next supplier negotiation before the last one is fully implemented. Research suggests that buyers aren’t always fully prepared going into negotiations — usually because they don’t have enough time to develop a strategy or enough data about the supplier’s position.
Payment Benchmarking Doesn’t Exist Inside Your Four Walls
You can measure your own payment performance. But the question that actually moves the needle in a negotiation is: what are other companies paying this same supplier? That external context is what turns “we’d like better terms” into a data-backed business case. And it’s not something any single company can generate on its own.

The Diamond on the Ground: Working Capital Acceleration
Here’s what’s worth remembering: this isn’t something your teams have overlooked. It’s an opportunity that’s been sitting there, waiting for the right combination of data and bandwidth to pick it up.
PRGX has built a Working Capital Acceleration program designed for exactly this moment. Custom Supplier Playbooks arm your procurement team with anonymized industry benchmarks, public data peer comparisons, and a specific recommended ask — with the working capital impact quantified. One specialty retailer used this approach to achieve a 7x ROI from a single supplier negotiation and over $10M in total working capital improvement.
To sustain the gains, they deployed PRGX Spend & Payment Insight™, a spend analytics platform that provides real-time visibility into payment performance across the supplier base, so new terms actually stick and new opportunities surface as spend shifts over time.
