How to use your finance partner to improve supplier relationships and cash flow

Improving cash flow starts long before money leaves the bank. For many UK businesses, the real strain comes from waiting too long for payments or navigating disputes with key suppliers. Recent research shows that 9 in 10 UK companies experienced delayed payments in 2025, placing real pressure on working capital and planning.

That is why working with a finance business partner to apply strong vendor relationship management best practices has become critical. It gives growing businesses real control over supplier payments, disputes and working capital.

Why finance-led vendor management now drives cash flow

Deloitte’s 2026 UK CFO Survey shows why this model is accelerating. It found that 96% of CFOs expect investment in digital finance systems to rise over the next five years, while 59% are now more optimistic about AI improving organisational performance.

This shift is turning finance teams and their partners into active managers of cash. When your finance partner controls vendor data and payment flows in real time, supplier relationships become predictable and cash flow positive.

That predictability is what improves supplier payments, fewer errors, faster approvals and fewer disputes delaying money from leaving the bank.

Standardise how to manage vendor relationships

Most late or incorrect supplier payments are caused by missing data, mismatched purchase orders or unclear terms, not lack of cash.

Clear, consistent processes are the foundation for healthy vendor relationships. Start with documented onboarding that captures banking details, contacts, purchase order rules and payment terms.

Standardising how to manage vendor relationships also reduces disputes before they reach your finance team, which directly protects cash flow and supplier trust.

Encourage proactive finance partner involvement

So what is a finance business partner in this context? It is the function, often outsourced, that owns supplier data, payment controls and cash flow forecasting across the business. Rather than reacting to invoices at month end, they monitor what is coming, what is due and where risk is building.

A senior finance business partner leads cross-functional reviews across procurement, operations and accounts payable to keep payments accurate and cash outflows aligned to forecasts.

Tracking metrics such as invoice approval time, dispute frequency and payment accuracy gives both your finance partner and suppliers a shared view of performance. Transparent reporting builds trust and highlights problems early, before they damage working capital.

Align payment terms and review regularly

If your finance team feels stretched or your cash flow is unpredictable, now is the time to refine how vendors are managed through your finance partner.
