Days Payable Outstanding measures the average number of days a company takes to pay its suppliers after receiving an invoice. A higher DPO means the company holds cash longer before paying, which improves working capital. Supply chain finance programs allow buyers to extend DPO without creating financial stress for suppliers.
What It Is #
DPO is one of the three core metrics that make up the Cash Conversion Cycle. It represents how efficiently a company manages its accounts payable — specifically, how long it delays outgoing payments while still maintaining supplier relationships.
A high DPO is positive for the buyer: it means cash stays in the business longer, reducing the need for external financing. However, excessively long payment terms — imposed without offering suppliers an alternative — can damage relationships, destabilise the supply chain, and invite regulatory scrutiny.
The Formula #
DPO = (Accounts Payable / Cost of Goods Sold) × Number of Days
Interpreting DPO #
| DPO Range | What It Signals |
|---|---|
| Under 30 days | Paying very quickly — possibly leaving working capital on the table |
| 30–60 days | Industry standard for most sectors |
| 60–90 days | Extended terms — common in retail and manufacturing with SCF programs |
| 90–120+ days | Aggressive extension — requires SCF program to maintain supplier health |
DPO and Supply Chain Finance #
Extended payment terms improve DPO but create a cash flow gap for suppliers. This tension is resolved by reverse factoring: buyers extend DPO to 90 or 120 days, while suppliers access early payment through the programme within 5 days.
Example: Extending DPO from 30 to 90 days on €120 million in annual supplier spend frees up approximately €16.4 million in additional working capital (60 extra days × €120M ÷ 365).
