Payment Behaviour Analysis: testing and quality assurance Sector

This report presents a detailed analysis of payment behaviour within the testing and quality assurance sector, based on a sample of 20 companies situated across the United Kingdom. Upon reviewing the central tendency metrics, we observe a notable disparity between the mean and median figures. Whilst the median payment time stands at a respectable 35 days, the average extends to 43.5 days. This divergence suggests a positive skew, indicating that a minority of poor performers are disproportionately affecting the overall sector average. Consequently, the median figure of 35 days arguably represents a more accurate centre of gravity for typical company performance in this industry. The standard deviation of 26.5 days further highlights this volatility, signalling that payment terms are far from uniform across the sample group.

When we organise the data by payment speed, distinct clusters of behaviour emerge. A substantial proportion of the sector appears to favour prompt settlement, with 40.0% of analysed companies (8 firms) settling invoices within the 0-30 day window. The quartiles further illuminate this trend; the 25th percentile sits at 28 days, whilst the 75th percentile extends to 54 days. The interquartile range of 26 days suggests that whilst the "middle 50%" of companies are reasonably predictable, there is still a wide window of uncertainty for suppliers managing cash flow. It is crucial to realise that nearly half of the sector (45.0%) falls into the "Moderate" to "Slow" categories (31-60 days), implying that extended credit terms are becoming a normalised practice amongst many mid-tier performers.

A critical review of the performance breakdown exposes significant risks at the tail end of the distribution. Despite the fact that 46.2% of payments are made within 30 days, a worrying 23.2% stretch beyond 60 days, with 21.4% officially classified as late payments. The data reveals extreme outliers that characterise the sector's instability; whilst the fastest payer settled accounts in an impressive 17 days, the slowest payer took a staggering 132 days. This "Critical" segment—specifically the 5.0% of companies taking over 90 days—presents a severe liquidity risk. Suppliers specialising in this sector must be wary of these outliers, as the gap of over 100 days between the best and worst performers necessitates robust credit control procedures.

Geographically, the analysed companies are distributed across major UK economic hubs, with London serving as the primary centre (5 companies), followed by equal representation in the North West, South West, and Yorkshire and The Humber. Ultimately, the data paints a picture of a divided sector. On one hand, nearly half the market demonstrates healthy payment habits; on the other, a significant "long tail" of slow payers exists. Business analysts observing this sector must recognise that whilst the median performance is acceptable, the high standard deviation and the presence of extreme delays require suppliers to favour strict due diligence over assumption when extending credit terms.
