Days Payable Outstanding (DPO)
In briefDays Payable Outstanding indicates how many days on average a company takes to pay its suppliers. A longer DPO conserves liquidity and improves working capital, but a sharp increase can point to forced payment stretching and liquidity problems.
Definition
Days Payable Outstanding measures the average time in days a company takes to settle its trade payables. A higher value means invoices are paid later and suppliers effectively finance the company. Alongside receivables days and inventory days, DPO is a component of the cash conversion cycle.
How it is calculated
Formula. DPO = (trade payables ÷ cost of materials) × 365 days
Why it matters for small caps
For small companies, a sharply rising DPO can point to liquidity bottlenecks when payments are deliberately stretched. At the same time, a longer DPO improves working capital but can strain supplier relationships.
Common misreadings
- A rising DPO is broadly interpreted as good working capital management, even though it can also be forced payment stretching under liquidity distress.
In the process
Frequently asked
How does a higher DPO affect liquidity?
It ties up less capital because invoices are paid later, thereby improving the cash conversion cycle.
When is a rising DPO a warning sign?
When it is not based on negotiated terms but on forced payment stretching due to liquidity bottlenecks.
How does DPO relate to the cash conversion cycle?
The cash conversion cycle results from inventory and receivables days less the payables period, i.e. the DPO.
