Dispute resolution
The accounts payable team will receive an email with a complaint or concern from the supplier. The details will be fact checked and the information reviewed to see why the supplier has not been paid. This is often due to suppliers not having a valid invoice due to lack of PO etc. The accounts payable team will work to rectify the issue as quickly as possible and pay the supplier as soon as possible.

How UK payment reporting works
What is a Payment Practices Report?
What does "paid outside agreed terms" mean?
How often is this data updated?
Is this official government data?
How this is compiled. Built from official records only: Companies House and the gov.uk payment-practices service. The payment figures are self-reported — companies over the size threshold must file them by law and the board signs them off. No credit-agency data. The numbers are theirs; the plain-English read is ours. This is information compiled from public records under the Open Government Licence v3.0 — not a credit rating and not advice.
The 31-day comparison figure is the median across 6,104 companies with a current statutory report — every sector pooled, not an average of sector medians (how the figure is built).
