What is Days Payable Outstanding (DPO)?

Days Payable Outstanding (DPO) Definition

Days Payable Outstanding (DPO) is a financial metric measuring the average time (in days) a company takes to pay its bills and invoices to its suppliers, vendors, and other creditors. It is an important indicator for cash flow management.

Understanding Days Payable Outstanding in B2B Finance

Days Payable Outstanding is a critical financial metric in B2B finance because it helps businesses maintain supplier relationships, optimize cash flow, and ensure financial health. When a company has a high DPO, it means they are holding onto their cash longer, giving them more flexibility to use this cash for other essential activities like investing or paying off debt. It is a smart strategy to maximize the use of supplier credit, essentially borrowing for free.

High vs. Low Days Payable Outstanding

A high and low DPO affects a company's liquidity, supplier relationships, and overall financial strategy. A high DPO can enhance cash flow flexibility, but it's crucial not to stretch supplier patience too thin. A low DPO fosters good supplier relations and may unlock perks, but needs to be balanced against the opportunity cost of not utilizing cash elsewhere. Understanding the difference between these two concepts can offer deep insights into financial health and operational efficiency.

High DPO

  • A high DPO allows a company to use the cash for other critical operations, investments, or growth opportunities, effectively increasing its liquidity. For example, if a technology firm negotiates 90-day payment terms with its component suppliers, it can use the retained cash to fund research and development projects or expand its product line in the meantime.
  • However, a higher DPO might indicate that a company is delaying payments to manage cash shortages, which could strain supplier relationships. If suppliers start feeling that they're being paid too late, they might enforce stricter payment terms or increase prices to mitigate their risk.


  • A low DPO indicates quick invoice payments, often well within the payment terms. It's benefits include strong supplier relationships, potentially leading early payment discounts, priority delivery, or more favorable terms in future dealings. For example, a manufacturing company paying its raw material suppliers within 30 days might receive a 2% discount on all purchases, improving its cost of goods sold (COGS).
  • On the downside, paying too quickly could mean a company isn't using its available cash as efficiently as possible. Instead of taking advantage of the credit terms offered, which could allow for better cash flow management or investment in high-return opportunities, the company chooses to settle payables sooner, possibly missing out on earning potential interest on the cash or investing in growth opportunities.

Days Payable Outstanding vs. Days Sales Outstanding

Days Payable Outstanding (DPO) and Days Sales Outstanding (DSO) are key financial metrics that provide deep insights into a company's operational efficiency and financial health. While both measure the time a company takes to fulfill certain financial obligations, they focus on different aspects of the cash flow. Here's a breakdown of the differences:

DPO measures the average number of days a company takes to pay its suppliers and creditors. A higher DPO means the company holds onto its cash longer, potentially using it for other investments or operations. DPO is a key indicator of how well a company manages its outgoing cash flow and payables.

DSO, on the other hand, calculates the average number of days it takes for a company to collect payment after a sale. A lower DSO indicates that the company is more efficient at collecting customer payments, improving its incoming cash flow. DSO reflects how well a company manages its accounts receivable and the efficiency of its credit policies.

DPO and DSO are components of the Cash Conversion Cycle (CCC), which measures how quickly a company turns its inventory into cash. The formula for CCC involves both DPO and DSO, along with Days Inventory Outstanding (DIO). A company aiming to improve its cash flow would seek to increase DPO (pay slower) and decrease DSO (collect faster), thereby shortening its Cash Conversion Cycle and improving liquidity.

Key Differences between DPO vs. DSO

  • DPO focuses on payables (money going out), while DSO focuses on receivables (money coming in).
  • DPO shows how long a company can use its cash before settling its payables, potentially benefiting from the cash on hand. DSO demonstrates how quickly a company converts its sales into cash, affecting its liquidity.
  • Improving DPO might involve negotiating longer payment terms with suppliers while enhancing DSO could require tightening credit terms or improving billing procedures to ensure quicker customer payments.

Days Payable Outstanding Calculation

Calculating Days Payable Outstanding is a straightforward process that tells us how long a company typically takes to pay its suppliers. By calculating DPO, a company can evaluate its payment policies and how they affect its cash flow. It is a crucial measurement for understanding a company's cash flow and how efficiently it manages its short-term finances. Here's a step-by-step guide for DPO calculation:

Gather Necessary Financial Information

  • First, find the total accounts payable and the cost of goods sold (COGS) from the financial statements. You also need the number of days in the period you're examining (usually 365 days for a full year).

Daily COGS Calculation

  • Find the daily cost of goods sold to understand how much the company spends on goods sold each day, on average.
Formula: Daily COGS = COGS / Number of Days


DPO Calculation

  • Finally, calculate DPO to understand the average days the company takes to pay its suppliers.
Formula: DPO=(Accounts Payable / Daily COGS)

Benefits of Days Payable Outstanding

By carefully managing DPO, companies not only ensure they have the cash needed to operate effectively but also position themselves for strategic growth and stability. Understanding the nuances of DPO offers a clear advantage in financial management, providing a foundation for solid business decisions and long-term planning. Here are the benefits of understanding and managing DPO effectively. 

Improves Cash Flow Management

Understanding DPO helps companies to manage their cash flow better. By extending payment periods without incurring penalties, a company can retain more cash on hand. This liquidity can be used for various operational needs, investments, or emergency funds, providing flexibility in financial planning.

Leverages Credit Terms

Knowledge of DPO allows businesses to make the most of their suppliers' credit terms. If a company knows it consistently maintains a high DPO within acceptable limits, it can negotiate longer payment terms with confidence, effectively using suppliers' credit as an interest-free loan.

Enhances Supplier Relationships

While managing DPO, companies also focus on maintaining healthy relationships with their suppliers. By understanding their payment capabilities, they can negotiate favorable terms for both parties, ensuring reliability and stability in their supply chain.

Strategic Investment and Growth

With a higher DPO, companies have more cash available for strategic investments. Instead of tying up funds in early payments, they can invest in growth opportunities, research and development, or even acquisitions, contributing to the company’s long-term success.

Optimizes Working Capital

Effective DPO management contributes to optimizing working capital by balancing the use of cash for payments with the need for liquidity in operations. This balance is crucial for the smooth functioning and financial health of a company, allowing for better handling of operational expenses and investment activities.

Scenario Analysis

Including DPO in financial modeling enables scenario analysis, where analysts can assess how changes in payment policies might affect the company's financial health. This can be crucial for strategic planning, risk management, and operational efficiency.

Guidelines to Improve Days Payable Outstanding

By optimizing the time your business takes to pay its suppliers, you can better manage cash on hand, allowing for strategic investments and operations improvements. Here are some best practices for improving DPO in a manner that maintains healthy supplier relationships and supports your business goals:

Understand Supplier Payment Terms

Start by thoroughly reviewing the payment terms of all your suppliers. Understand the maximum time you can take to pay without incurring penalties or damaging the relationship. This knowledge allows you to strategize payments to optimize cash flow.

Negotiate Longer Payment Terms

Whenever possible, negotiate longer payment terms with suppliers. This doesn’t mean taking advantage of your suppliers but rather seeking a mutual agreement that benefits both parties, potentially offering something in return like larger orders or a long-term commitment.

Leverage Technology for Payment Scheduling

Use a accounting software to schedule payments as close to the due date as possible without being late. This ensures you retain cash longer, improving your cash flow while still honoring agreed payment terms.

Maintain Good Supplier Relationships

Communicate openly with suppliers about your payment policies and any potential delays. Maintaining a positive relationship can lead to better terms and understanding, even when payments are strategically delayed.

Analyze Purchase Orders and Inventory

Manage your inventory and purchase orders efficiently. Overstocking or premature ordering ties up cash unnecessarily and can adversely affect your DPO. Aim for just-in-time inventory to optimize cash flow.

Use Early Payment Discount Wisely

If suppliers offer early payment discounts, calculate whether the cost savings improve your overall cash flow more than the benefits of a higher DPO. Taking a discount is more advantageous than extending payables.

Monitor DPO Regularly

Regular monitoring of your DPO can provide insights into how changes in your payment practices affect cash flow and operational efficiency. Adjust your strategies to maintain an optimal balance between cash on hand and supplier relationships.

Educate Your Procurement and Accounts Payable Teams

Ensure your procurement and accounts payable teams understand the importance of DPO and how it impacts the business. Following the best practices in vendor negotiations and payment processes can significantly improve your DPO.


1. What is a DPO Ratio?

The DPO ratio, short for the Days Payable Outstanding ratio, measures the average number of days a company takes to pay its suppliers and creditors. It indicates how well a company manages its cash outflow by utilizing supplier credit. By calculating this ratio, businesses can evaluate their efficiency in managing payables. A higher DPO ratio suggests that a company retains cash longer, which can be beneficial for liquidity and operational flexibility. Conversely, a lower DPO ratio means the company pays its debts quicker, which might indicate efficient payment practices but also suggests less cash on hand for other uses. Understanding the DPO ratio helps companies balance between maintaining healthy supplier relationships and optimizing their cash flow management.

2. What is the difference between DPO and Accounts Payable Turnover?

Days Payable Outstanding (DPO) and Accounts Payable Turnover both analyze a company's payment habits but from different perspectives. DPO measures the average number of days a company takes to pay its suppliers, highlighting how long it holds onto its cash. A higher DPO suggests more extended payment terms, beneficial for cash flow. In contrast, Accounts Payable Turnover shows how frequently a company pays off its suppliers over a period, calculated by dividing total purchases by average accounts payable. A higher turnover rate indicates more frequent payments, suggesting quicker payment practices. While DPO focuses on timing, Accounts Payable Turnover focuses on payment frequency, offering insights into the company's cash management and supplier relationship strategy.

3. How is DPO related to Ending Accounts Payable?

Days Payable Outstanding (DPO) and ending accounts payable are closely related concepts in accounting that help assess a company's financial health and cash flow management. DPO measures the average number of days a company takes to pay its suppliers, indicating how efficiently it manages its cash outflows. Ending accounts payable, on the other hand, refers to the total amount owed to suppliers at the end of a financial period, captured on the balance sheet. Together, these metrics provide insights into a company's payment practices and liquidity. A higher DPO can suggest better cash on hand, as the company takes longer to pay off its debts, while the ending accounts payable amount gives a snapshot of the company's short-term liabilities. Understanding both helps businesses make informed decisions about managing their supplier payments and cash flow.

4. What is a DPO Value?

A DPO value, or Days Payable Outstanding value, quantifies the average number of days a company takes to pay its suppliers after receiving goods or services. This financial metric is a key indicator of how a company manages its cash outflows and payables. A higher DPO value suggests that a company holds onto its cash longer, potentially using it for other operational needs or investments, which can be beneficial for cash flow management. Conversely, a lower DPO value indicates quicker payments to suppliers, which may reflect a company's strategy to take advantage of early payment discount or maintain strong supplier relationships. Understanding the DPO value is essential for businesses to balance between utilizing their cash efficiently and sustaining good terms with their vendors.

5. What is a Payable Outstanding?

A payable outstanding refers to the amount of money a company owes to its suppliers or creditors for goods and services received but not yet paid for. This figure represents short-term liabilities recorded on the company's balance sheet as accounts payable. It indicates how much the company needs to set aside or pay out shortly to settle its debts. Here's a Payable outstanding example, if a company makes $200,000 in purchases over a year and has $25,000 in accounts payable at year-end, with daily purchases of $548.95, its Days Payable Outstanding (DPO) would be approximately 45 days. This shows the company takes about 45 days on average to pay its suppliers.

6. What is the Accounts Payable Balance?

The accounts payable balance represents the total amount of money a company owes to its suppliers or creditors for goods and services received but not yet paid for. It appears on the company's balance sheet under current liabilities, as these obligations are typically due within one year. The accounts payable balance is crucial for understanding a company's short-term financial commitments. By managing this balance efficiently, a company ensures it maintains good relationships with its suppliers while optimizing its cash flow. Tracking the accounts payable balance helps businesses to budget for upcoming expenses and negotiate payment terms that align with their cash management strategies.
