What is Days Payable Outstanding (DPO)? What issues should be considered?


Days Payable Outstanding (DPO) is an indicator that measures the speed at which a business pays its suppliers' accounts payable.

What is Days Payable Outstanding (DPO)?

Days Payable Outstanding (DPO) is a metric used to measure the speed at which a company pays its suppliers. It reflects the average time from when a company receives an invoice from a supplier to when it pays off its accounts payable. The formula for calculating DPO is as follows:

Days Payable Outstanding = (Ending Accounts Payable / Cost of Purchases) × 365

Here, Ending Accounts Payable refers to the balance of accounts payable at a specific point in time, while Cost of Purchases represents the total purchasing expenditures over a period.

A lower DPO value indicates that a company pays off its accounts payable more quickly, which suggests a higher efficiency in capital use; a higher DPO value, however, indicates slower payment processes, possibly due to improper use of funds or poor supply chain management.

DPO is significant for a company's operational management and supply chain management. By monitoring and analyzing DPO, companies can assess the efficiency and payment capability in their cooperation with suppliers, optimize cash flow management, and improve the stability and efficiency of the supply chain.

It's important to note that the ideal range for DPO varies by industry and company characteristics. It should be evaluated and compared in context. Also, it should be analyzed in conjunction with other financial metrics and operational data for a comprehensive assessment of the company's financial health and supply chain operations.

What Issues Should We Pay Attention to Regarding DPO?

How to Improve DPO?

  • Negotiate payment terms with suppliers: Negotiate for more favorable payment terms with suppliers, such as extending the payment period. This can allow you to delay payments, extending the accounts payable turnover cycle.
  • Optimize supply chain processes: Review supply chain processes to identify optimization opportunities, reducing delays and bottlenecks. Ensure the efficiency of supply logistics and the purchasing process to promptly receive invoices and process payments.
  • Automate accounting processes: Consider implementing automated systems for managing accounting transactions, such as electronic procurement and payment systems. These systems can improve efficiency, reduce manual errors and delays, speeding up accounts payable processing.
  • Strengthen supplier relationship management: Build strong relationships with suppliers, establishing long-term partnerships. Through trust and effective communication, cooperation can be enhanced, increasing suppliers' flexibility and tolerance towards you.
  • Forecast and plan cash flow: Accurately forecast and plan cash flows to ensure sufficient funds for timely accounts payable payments. This can help avoid payment lags and overdue payments, thereby reducing DPO.
  • Optimize financial processes: Review financial processes for more efficient methods of handling accounting transactions. For instance, streamline approval and payment processes to reduce unnecessary checks and speed up transaction processing.
  • Coordinate internal departments: Strengthen cooperation and coordination among the purchasing department, finance department, and supply chain department. Ensure timely and accurate information acquisition for prompt accounts payable processing.

How Does a Change in DPO Affect Financial Health?

  • Cash flow: Extending DPO can delay payments to suppliers, thus freeing up more cash for day-to-day operations or other investments. This can be beneficial for companies with tight cash flow conditions, improving liquidity and reducing external financing needs.
  • Cost of capital: By extending DPO, companies can retain funds longer before paying suppliers, using this time to earn interest or other investment returns. This can lower the cost of capital, as funds remain within the company longer.
  • Supplier relationships: Excessively long DPO may negatively affect supplier relationships. Prolonged payment delays can disrupt suppliers' cash flow, decrease satisfaction, and potentially lead them to refuse favorable cooperation terms. Maintaining good supplier relationships is crucial for ensuring supply chain stability and effective cooperation.
  • Reputation and credibility: Long delays in paying suppliers can negatively impact a company's reputation and credibility. This may make future business partners hesitant to establish cooperative relations, thus limiting the company's growth and business opportunities.

It's worth noting that extending DPO is not always beneficial, and a comprehensive evaluation and cautious analysis should be conducted before doing so. When deciding whether to extend DPO, balance factors such as cash flow needs, supplier relationships, company image, and cost of capital. Each company should assess and manage changes in DPO in accordance with its own situation and strategic objectives.

What is the Relationship Between DPO and Days Sales Outstanding (DSO)?

Days Payable Outstanding (DPO) and Days Sales Outstanding (DSO) are two interrelated metrics used in financial management to measure a company's operational capacity and liquidity.

DPO indicates the average time a company takes to pay its suppliers, measuring the company's ability to delay payments. A longer DPO signifies the company delays payments to suppliers longer, thus extending the accounts payable turnover cycle.

DSO indicates the average time a company takes to collect payments from customers, measuring the company's ability to recover accounts receivable. A longer DSO signifies the company needs more time to collect sales proceeds, thus extending the accounts receivable turnover cycle.

The relationship between these two metrics can be understood through the Cash Conversion Cycle (CCC), a comprehensive metric calculated as:


Here, DIO stands for Days Inventory Outstanding, measuring the turnover speed of a company's inventory.

CCC reflects the time it takes for a company to convert raw material purchases into cash from sales. A longer CCC means that the company requires more time to convert costs into cash, implying higher liquidity needs.

It is evident that DPO and DSO directly impact CCC. Extending DPO increases CCC, as funds stay longer within the company; likewise, extending DSO also increases CCC, as it takes longer to convert sales into cash.

Therefore, when managing cash flow and liquidity, companies should consider optimizing both DPO and DSO to reduce CCC and improve capital turnover efficiency. This can be achieved by optimizing procurement, supply chain, and sales processes, as well as strengthening relationships with suppliers and customers.

What are the Reference Standards for DPO?

There is no fixed value for the reference standards of Days Payable Outstanding (DPO), as a reasonable DPO value varies by industry, company size, supply chain structure, and business model. Payment terms and business practices also differ across industries and companies.

Generally, a longer DPO value indicates that a company can delay payments to suppliers longer, thus extending the accounts payable turnover cycle. This may positively affect the company's cash flow, as it provides more time to use funds for operations or investments.

However, excessively long DPO can negatively impact supplier relationships. If a company overly delays payments, it may disrupt suppliers' cash flow, leading to dissatisfaction and a decreased willingness to cooperate.

Therefore, companies need to balance when determining an appropriate level of DPO. On one hand, ensure sufficient cash flow to pay suppliers on time; on the other hand, maintain good cooperative relationships with suppliers to ensure supply chain stability.

To determine an appropriate DPO target, the following methods can be considered:

  • Industry comparisons: Understand the average DPO level within the industry and compare it with competitors. This provides a reference point to understand industry practices and trends.
  • Company's actual situation: Assess the appropriate DPO target based on the company's financial condition, operational needs, and supply chain structure. Consider factors like cash flow needs, supplier relationships, and purchasing strategies, and discuss and analyze these with finance and purchasing teams.
  • Cost of capital and supplier relationships: Consider the cost of capital and the relationships with suppliers, balancing the cash flow advantages of extending DPO and supplier satisfaction. Ensure extending DPO does not adversely affect the supply chain.
