Help with overdue invoices: practical business advice to get paid faster in 2026

4 February 2026

In a 2025 report, global Days Sales Outstanding (DSO) rose by two days, reflecting longer payment terms and slower average invoice collection worldwide. In Western Europe, businesses experienced a notable increase in working capital requirements, driven in part by higher levels of outstanding receivables, meaning many companies were effectively acting as informal lenders by waiting longer to receive payment.

This shows just how widespread overdue invoices have become nowadays. Unpaid invoices can disrupt cash flow, tie up working capital, and create extra pressure on finance and credit control teams. As chasing late payments is time-consuming and often unproductive, more businesses are looking for ways to protect themselves from the impact of overdue invoices.

One of these ways is by taking a more systematic approach to reducing late payments. By implementing monitoring systems, internal policies, and financial tools, companies can minimise the impact of overdue invoices and improve overall cash flow management.

Summary

  • Overdue invoices or unpaid payments can create cash flow problems, strain supplier and customer relationships, and even damage your company’s reputation.
  • Implementing clear credit policies, tracking and monitoring invoices, and using escalation processes helps reduce overdue invoices and protects your business from financial strain.
  •  
  • Leveraging financial safeguards such as trade credit insurance, customer credit insights, and flexible payment options ensures you maintain control over receivables and can make informed, strategic decisions.
     

Proactive tracking is crucial for preventing overdue invoices from escalating into serious financial issues. Businesses often rely on spreadsheets or manual systems, which can make it difficult to see overdue payments in real time. By using automated dashboards and reporting tools, you get a clear, up-to-date overview of outstanding invoices and can also identify trends.

  • Real-time visibility: Monitor outstanding invoices, payment due dates, and overdue amounts at a glance.
  • Early detection of high-risk accounts: Identify clients who regularly pay late or have large outstanding balances, allowing your team to take timely action.
  • Segmentation by risk factors: Categorise invoices by industry, client history, and payment amounts to prioritise follow-ups efficiently.

A well-defined escalation policy ensures overdue invoices are managed consistently and systematically across your business. Without a clear policy, invoices can fall through the cracks, resulting in delayed revenue and additional workload.

  • Assign responsibility: Allocate specific team members to handle overdue invoices, to ensure accountability and continuity.
  • Maintain records: Keep detailed documentation of all communication and actions taken, which can be crucial if further debt recovery steps are required.

If your business has a structured approach to overpaid invoices, this helps to reduce confusion, speed up collections, and demonstrate professionalism to clients, which all means you are more likely to be paid on time.

Even with strong monitoring and internal processes, some overdue invoices are unavoidable. In these circumstances, financial tools, such as bad debt protection and trade credit insurance, provide an extra layer of security for your business.

  • Bad debt protection covers losses from customer insolvency, guaranteeing that unpaid invoices don’t significantly impact your finances.
  • Client-specific credit limits based on risk factors such as past payment behaviour or sector-specific vulnerabilities.
  • Prepayment or guarantees. For large orders or high-risk clients, ask for deposits, letters of credit, or full prepayment to mitigate exposure.

Overdue invoices should feed directly into your cash flow management strategy, and understanding the patterns of late payments allows you to make informed financial decisions. Consider these tips:

  • Integrate overdue invoices into forecasts to ensure monthly cash flow projections account for outstanding payments.
  • Identify trends by monitoring which clients, industries, or invoice sizes are most prone to late payment.
  • Proactive planning such as adjusting credit policies, negotiating payment plans, and making informed decisions about new client onboarding can all help to avoid overdue invoices.

Combining proactive monitoring, internal escalation policies, and financial tools can bring many benefits to businesses. Take a look at the advantages in our table for quick reference.

After implementing a more effective invoicing process, you might continue to see more overdue invoices than expected. If this is the case, speaking to your customers is the most important thing you can do.

With such clear consequences of not paying an overdue invoice, you may think a customer wouldn’t pay on time because they’re in dispute with your business or under financial pressure. A customer without the money to pay your invoice will have no other choice than to pay late (or not at all), while a customer unhappy with your service may not wish to pay until their issue is solved. However, another common reason is simple forgetfulness.

Overdue invoices can create cash flow pressure and slow down growth, but taking a proactive approach helps you stay in control. Clear payment terms, streamlined processes, and flexible options make it easier to reduce delays and encourage payments that are on-time, every time.

Why not consider trade credit insurance (TCI) to secure your cash flow? TCI is an insurance policy your business takes out, where a third-party insurer guarantees payment of your invoices, even if a customer can’t or won’t pay.

An overdue invoice is a bill that a customer has not paid by the agreed-upon due date. It represents outstanding payment that your business is owed and can impact cash flow if not managed immediately.

To politely chase an overdue invoice, start with a friendly reminder email or call, clearly referencing the invoice number, amount, and original due date. Keep the tone professional and courteous at all times. Request quick payment and offer help if there are any issues delaying it.

In the UK, there is no strict legal deadline for issuing invoices, but businesses are expected to send them promptly after supplying goods or services. However, payment terms agreed in contracts or under the Late Payment of Commercial Debts (Interest) Act 1998 must be honoured, which means you can charge an interest or a standard UK late payment fee on overdue invoices.

If an invoice is not paid within the agreed payment terms, the creditor can start enforcing their payment rights, which may include sending reminders, charging late payment interest, or taking legal action. In the UK, under the Late Payment of Commercial Debts (Interest) Act 1998, businesses can also claim statutory interest and debt recovery costs.
