Not all late payment problems are the same. A staffing agency chasing a 45-day invoice is dealing with a different problem than a construction firm waiting 83 days for a retention release, or a law firm trying to collect a six-figure fee without damaging a client relationship. We pulled together UK sector benchmarks on invoice payment times to show where your industry actually sits — and which sectors are the worst payers.
Ranked from longest average payment cycle to shortest, based on typical UK sector data:
Construction sits at the top of the list for a reason. Payment applications, retention withholding, and multi-tier subcontractor chains all stack delay on top of delay. An 83-day average isn't one slow client — it's a structural problem: cash sits locked in retention accounts long after the work is done, and chasing it means tracking applications for payment separately from chasing the actual invoice.
Solicitors, law firms, and legal services generally see 60-90 day cycles — and the fee sizes involved make manual chasing riskier. A £50,000 fee sitting unpaid for three months is a very different cash flow problem than a £500 invoice, but the awkwardness of chasing a corporate client for payment stops a lot of firms from following up as firmly as they should. Professional services more broadly (consultancies, agencies) see a wide 45-75 day range depending on client type.
Media, advertising, and adtech businesses often sit inside multi-party payment chains — advertiser to agency to platform — where a delay anywhere upstream cascades downstream. 60-90 day cycles are common. FinTech companies selling into enterprise clients see similar ~60-day terms, with the added risk that late payments there directly erode MRR, not just cash flow.
Engineering consultancies and services (50-70 days) and architecture and design firms (45-60 days) share a common thread with construction: milestone billing. Payment is tied to project stages, retention is withheld until final sign-off, and client revision requests routinely push milestones back — and payment with them.
Wherever your industry sits on this list, the fix is the same.
Equisettle automates invoice chasing and predicts which clients will pay late — before they do — so you're not finding out about a payment problem 60 days in.
Book NowLogistics and haulage operators run on some of the thinnest margins on this list — 30-60 day cycles are standard, but fuel costs and driver wages don't wait 60 days. Supply chain and logistics businesses more broadly face the same 45-60 day pattern, with the added complexity of managing collections across many smaller trade accounts rather than a handful of large clients.
E-commerce and wholesale businesses typically operate on 30-60 day trade terms — shorter than construction or legal, but with far higher transaction volume, meaning the operational burden of chasing is different: many small overdue accounts instead of a few large ones. SaaS and software companies face a subtler version of the same problem — late enterprise payments don't just delay cash, they distort MRR and runway forecasting. Security services sit closer to the middle of the pack at 45-60 days, often complicated by aligning corporate client billing with fixed payroll obligations.
Some sectors are already seeing what automated AR looks like in practice. Staffing and recruitment agencies using Equisettle have cut DSO by 15-20 days. Marketing and advertising agencies have reduced DSO by 30%. Engineering consultancy firms have cut 20-30 days off their cycle. None of these industries became easier to collect from — the process just stopped depending on someone remembering to chase, and started predicting which accounts needed attention before they went overdue.
Three factors explain most of the spread across industries: billing structure (milestone and retention-based billing runs slower than flat invoicing), chain length (the more parties between the work and the payment, the longer the delay), and relationship sensitivity (the more a business fears damaging a client relationship by chasing firmly, the longer it waits to escalate).
Which UK industry has the worst payment record?
Construction, with an average payment cycle of around 83 days, driven largely by retention withholding and multi-tier subcontractor chains.
Why do professional services firms wait so long to get paid?
A combination of milestone billing, complex fee structures, and reluctance to chase corporate clients firmly for fear of damaging the relationship.
Can automation actually reduce these payment cycles?
Yes — sectors already using automated AR tools have seen measurable reductions, from 15-20 days for staffing agencies to 30% DSO reductions for marketing agencies.
