Days Payable Outstanding (DPO) is a financial metric that measures the average number of days a company takes to pay its suppliers. It reflects the efficiency of a business’s accounts payable process and is a key component in assessing working capital management and cash flow strategies.
A company with a high DPO holds on to cash longer before paying invoices, while a low DPO indicates faster payments to suppliers. For finance leaders, procurement managers, and accounts payable (AP) teams, DPO offers insight into how well the business manages its outgoing payments relative to vendor terms and industry expectations.
Why does DPO matter?
DPO provides a window into the financial strategy and operational discipline of an organization. The timing of supplier payments impacts:
- Cash flow available for daily operations
- Working capital efficiency
- Supplier relationships and negotiation power
- Eligibility for early payment discounts
- Financial health and credit standing
Companies with mature AP processes manage DPO as part of a broader strategy to balance liquidity, cost control, and supplier trust. Many of these organizations rely on AP automation to ensure payment timing aligns with cash flow goals and supplier agreements. For this reason, DPO is a key metric for CFOs and finance leaders.

High vs. low DPO: what does it mean?
High DPO
A high DPO can support cash preservation. It allows the business to retain funds longer, which may improve internal liquidity. However, a high DPO can also lead to friction with suppliers, particularly if payments are late or terms are not honored.
Low DPO
A low DPO shows that the business is paying suppliers quickly. This may improve vendor satisfaction and unlock early payment discounts. However, it can also reduce cash available for other priorities if not carefully managed.
The “right” DPO depends on your industry, supplier base, and cost structure. What matters most is consistency, alignment with financial goals, and adopting smart DPO strategies that support both cash flow and supplier relationships.

How is DPO calculated?
The standard formula for DPO is:
DPO = (Accounts Payable ÷ Cost of Goods Sold) × Number of Days
This calculation reveals the average number of days a company takes to pay its bills. Finance teams typically track DPO monthly or quarterly to understand trends and compare performance over time.
What role does accounts payable play?
The AP team is central to managing DPO. They control how quickly invoices are received, reviewed, and paid. Key responsibilities that influence DPO include:
- Ensuring timely invoice capture
- Matching invoices with purchase orders and receipts
- Managing approval workflows
- Scheduling payments in line with supplier terms
A streamlined AP process allows finance teams to make informed decisions about when and how to pay suppliers. It also reduces the risk of late payments and strengthens financial control.

How automation helps optimize DPO
Manual processes make it difficult to manage DPO consistently. With AP automation in place, businesses gain visibility into invoice timelines, payment status, and supplier terms. This allows finance teams to:
Capture and validate invoices automatically
Route approvals efficiently
Track due dates and payment obligations in real time
Schedule payments to optimize and enhance cash flow
Generate reports that monitor DPO performance
Medius Payments complements AP automation by ensuring payments are scheduled accurately, executed securely, and aligned with supplier terms. Together, these systems help standardize disbursements and reduce the risk of late fees or manual errors.
Spreadsheets giving you a headache?
Manual reporting, particularly calculating DPO, is a real pain. All that endless data entry, the mind-numbing reconciliation, the clicking around in circles... it's a grind that keeps you from the insights that actually matter.

DPO as a tool for financial planning
DPO is more than a historical metric. When integrated with forecasting and analytics tools, it becomes a proactive tool for planning. Finance leaders use DPO insights to:
- Predict future cash flow needs
- Analyze supplier terms across business units
- Identify opportunities for working capital improvement
- Model the impact of payment timing on liquidity
Tracking DPO regularly supports better budgeting, financial agility, and risk management.

Benchmarks vary by industry. Manufacturing companies often have DPO cycles of 60 to 90 days, while service-oriented businesses may operate on 30-day terms. Use internal historical data and industry comparisons to guide targets.
DPO should be tracked monthly or quarterly. With automation, teams can monitor it continuously and act quickly when performance shifts.
Yes. Automation helps control invoice approval and payment timing, reduces errors, and ensures alignment with supplier terms.
