Manufacturing has always been the quiet backbone of the UK economy. Firms build the parts, materials and products that keep construction moving, supply retail, support infrastructure and feed export markets. Yet behind the machinery and the precision engineering lies a growing problem. Many manufacturers are struggling with long payment cycles and rising overdue invoices. These delays are starting to affect cash flow and investment decisions, and in some cases even survival.
It is not a new issue, but the scale has intensified. Several data sets now show that manufacturing is one of the hardest hit sectors when it comes to late payment and aged debt. For SMEs in particular, the pressure is becoming too strong to ignore.
This piece brings together the latest research, what it means for the industry and some practical steps that manufacturers can take to protect themselves.
Payment terms that stretch far beyond reason
According to Novuna’s 2025 analysis of the UK’s slowest paying industries, manufacturing now averages more than 80 days to be paid. That puts it firmly at the top of the late payment league table. It is not an occasional delay either. Long terms and slow settlements have become a structural feature of the sector.
Heavy goods suppliers, component makers and engineering firms know this pattern well. Many of their customers are larger organisations who use extended credit terms almost as standard operating practice. It may help the customer’s working capital, but it passes the burden on to the supplier. When a thirty day invoice becomes ninety, the manufacturer is effectively providing interest free credit.
The same Novuna research highlights that transport, administrative support services and wholesale trade are not far behind. These industries are often tightly linked to manufacturing supply chains, which increases the spread of slow payment behaviour across connected sectors.

The value of outstanding invoices is rising sharply
The size of the unpaid amounts is just as troubling as the delays. Bibby Financial Services recently reported that UK manufacturing SMEs are owed on average around £76,000 in unpaid invoices. More than six in ten manufacturers also said that customer payment times are getting worse, not better. A third of them have already experienced bad debt in the past year.
These numbers point to a growing imbalance. Materials, labour, energy and shipping costs have risen across the sector, yet the cash coming in is taking longer to arrive. That gap is exactly where financial stress builds.

National picture: late payment is widespread
Across the whole SME landscape, late payment continues to be one of the most disruptive forces. Studies from the Federation of Small Businesses and the Centre for Policy Studies suggest that roughly 77 percent of smaller firms are owed money at any given time. The average overdue balance sits around £20,000 to £30,000, but manufacturers report much higher figures.
Government research has also acknowledged the harm caused. Its recent Payment and Cash Flow Review points out that late payment is a factor in up to 50,000 business closures each year. That figure should give anyone pause. It is a reminder that late payment is not a minor irritation but a genuine contributor to business failure.

Regional hotspots are emerging
Data from FreeAgent, taken from thousands of SME invoices, shows that late payment is clustered in particular regions. In places like Southall, Blackburn and Nottingham, more than 70 percent of invoices are paid after the due date. Belfast and several towns across the Midlands and the North show similar figures.
For manufacturers operating in these areas, the impact is multiplied. Local supply chains mean that slow payment often cascades from one business to another, making recovery even harder.

Why manufacturers feel this pain more than others
It is worth asking why manufacturing appears to suffer more than many other sectors. The answer is a combination of factors.
Manufacturers typically deal in higher value invoices and rely heavily on predictable cash flow to pay for materials, machinery, labour and stock. Their customers often have stronger negotiating power and are able to dictate payment terms. Many operate on thin margins and cannot easily bridge a three month delay in settlement.
There is also the simple reality of operational focus. Most manufacturing SMEs do not have large credit control teams. Chasing debts takes time away from production and sales. Problems build gradually and silently, and by the time a business realises the scale of aged debt, it can be very difficult to unwind.
What manufacturers are doing in response
Some firms turn to invoice finance or factoring. These tools can help in certain cases but they come with a cost, and they do not always sit well with customer relationships. Others rely on internal chasing, which is often slow and takes staff away from the work that creates value.
A growing number of suppliers are starting to explore flexible repayment plans. Instead of discounting or escalating overdue invoices, they let customers choose a structured plan within rules set by the supplier. It is a way to recover older debt more smoothly without damaging the relationship or extending credit indefinitely.
This approach is rooted in fairness. It accepts that some customers genuinely struggle with cash flow and gives them a clear, manageable route to repay what they owe. It also gives the supplier visibility and automation, which reduces the administrative burden.
Where this leaves the sector
Manufacturing will continue to play a crucial role in the UK economy, but the late payment culture surrounding it is becoming unsustainable. It limits growth, undermines investment and forces good businesses into difficult financial positions. The data shows that the problem is not isolated and will probably intensify unless new methods are adopted.
There is an opportunity now for manufacturers to rethink how they handle overdue invoices. Whether through better processes, clearer terms or the adoption of repayment plan technology, even small changes can improve cash flow. In a sector where margins are under pressure, the ability to access owed money faster can make a surprising difference.
Late payment is not going away any time soon. But businesses do have choices. There are kinder, more efficient and more practical ways to manage the issue. The sooner the sector embraces them, the stronger and more resilient it will be.
