How Iop Publishing Limited compares
Iop Publishing Limited takes an average of 32 days to pay its suppliers, which is the same as the UK median of 32 days across 9,336 reporting companies. 40% of their invoices fall outside the agreed payment terms, compared to a national average of 24%. Their payment speed has been getting worse over time based on historical filings.
The “outside agreed terms” percentage measures how often the company pays after its own agreed payment terms, not against a fixed 30-day standard. A company with long payment terms can still be rated “Good payer” if it consistently meets those terms.
