Creditor days

Definition

Creditor days (or days payable outstanding) is the average time a company takes to settle supplier invoices, calculated as trade creditors divided by purchases, times 365. It's the payables counterpart to debtor days.

In plain terms

It shows how long you hold onto suppliers' money. Longer creditor days keep cash in your account — but stretch it too far and you damage relationships.

Why it matters for your company

Balancing creditor days against debtor days shapes your cash conversion cycle. Managed fairly, it eases working-capital pressure. See working capital management.

In practice

Picture a UK limited company buying stock or materials on standard supplier terms. From the invoice date, the finance team has an agreed window before payment is due. Creditor days simply reflect whether, on average, the company pays right on that line, settles early, or lets invoices run past the agreed date before releasing funds.

Where this becomes a live decision is in the ordering-to-payment rhythm: a director choosing when to release a payment run, whether to batch supplier payments monthly or weekly, and whether to take early-payment discounts a supplier offers versus holding the cash a little longer. None of these choices show up on the balance sheet directly — they surface later as a longer or shorter creditor-days figure at year end.

How lenders read it

A lender looking at creditor days alongside debtor days is really asking one question: is the business financing its operations on supplier terms because that's efficient treasury management, or because collections from customers have slowed and suppliers are the only flexible pressure valve left. The same headline number can mean either, so it is normally read next to the trend line and against the cash conversion cycle rather than in isolation.

A pattern of creditor days steadily lengthening, particularly if it coincides with debtor days also stretching, tends to draw more scrutiny than a stable figure — even a relatively long one — because stability suggests the terms are negotiated and controlled rather than a symptom of strain.
