Late payments: how can businesses protect their cash flow?

Late payments remain one of the most common cash-flow challenges facing UK businesses.

A profitable business can still experience financial pressure when customers fail to pay invoices on time. Wages, supplier costs, rent, tax and other commitments must still be met, regardless of whether expected payments have arrived.

With new measures proposed to address poor business payment practices, now is a sensible time for businesses to review how they issue invoices, agree payment terms and manage overdue accounts.

Why Late Payments Cause Problems

Cash flow is the movement of money into and out of a business.

When customers pay late, the business may not have sufficient available cash to meet its own commitments, even where its sales figures appear healthy.

Persistent late payments can:

  • Place pressure on working capital
  • Make financial planning more difficult
  • Delay investment and growth
  • Affect relationships with suppliers
  • Increase reliance on borrowing
  • Take management time away from running the business

For smaller businesses in particular, one substantial unpaid invoice can have a significant impact.

Set Clear Payment Terms

Payment expectations should be established before work begins.

Contracts, engagement letters, quotations and invoices should clearly explain:

  • When payment is due
  • How payment should be made
  • Whether deposits or staged payments are required
  • What happens if an invoice is disputed
  • Whether interest or recovery charges may apply
  • The process for dealing with overdue balances

Clear terms can reduce misunderstandings and provide a stronger position if recovery action becomes necessary.

Invoice Promptly and Accurately

Delays or mistakes when issuing invoices can give customers a reason to delay payment.

Businesses should ensure invoices are sent promptly and include all required information, such as:

  • The correct customer details
  • A clear description of the goods or services
  • The agreed price
  • Purchase-order information where applicable
  • The payment due date
  • Bank or payment details

It is also helpful to confirm who is responsible for approving and paying the invoice within the customer’s organisation.

Introduce a Consistent Credit-Control Process

Chasing payments can feel uncomfortable, particularly where a business has a long-standing relationship with the customer. However, consistent credit control is a normal part of running a business.

An effective process may include:

  • A reminder shortly before the due date
  • Contact as soon as an invoice becomes overdue
  • Regular follow-ups
  • Written records of conversations and promises to pay
  • Escalation where agreed dates are missed
  • A clear point at which further work or credit will be suspended

The process should be applied consistently rather than waiting until cash flow becomes urgent.

Consider the Customer Before Offering Credit

Before agreeing substantial credit terms, businesses should consider whether the customer is likely to be able to pay.

Credit checks, Companies House information, trade references and payment history can all help inform this decision.

Businesses should also consider setting appropriate credit limits and requesting deposits from new customers or for substantial pieces of work.

Could Invoice Finance Help?

Invoice finance may allow a business to access a proportion of the value of unpaid invoices without waiting for the customer’s normal payment date.

This can improve working capital and provide more certainty around cash flow.

However, invoice finance will not be appropriate for every business. The costs, terms, customer profile and existing finance arrangements should all be reviewed before proceeding.

Review Your Legal Options

Where an invoice remains unpaid, legal advice may be required.

The most appropriate action will depend on the contract, the amount involved, whether the invoice is disputed and the customer’s financial position.

Taking advice early may prevent the debt from becoming more difficult or costly to recover.

Take Control of Your Cash Flow

Businesses cannot always prevent customers from paying late, but they can reduce the risk through clear terms, accurate invoicing and consistent credit control.
