    Unpaid invoices are one of the biggest challenges for businesses

    Late payments are a major problem for businesses across the UK. According to the Federation of Small Businesses, over 50,000 businesses close each year because of cashflow problems — and unpaid invoices are a leading cause.

    Many companies struggle with:

    • Customers ignoring invoices or delaying payment without explanation
    • Late payments damaging cashflow and making it hard to cover costs
    • Awkward conversations about money that strain client relationships
    • No clear process for escalating overdue accounts

    Recovering unpaid invoices requires a structured, consistent process. The businesses that get paid fastest are the ones with a clear credit control workflow — whether manual or automated. This guide walks you through a proven 7-step approach.

    7 steps to recover unpaid invoices

    A practical, step-by-step credit control process used by thousands of UK businesses.

    Step 01

    Confirm the invoice is actually overdue

    Before taking any action, verify the basic facts. Many payment delays are caused by simple administrative issues rather than deliberate non-payment.

    Check the following before escalating:

    • What are the agreed payment terms? (e.g. 30 days, 14 days, on receipt)
    • Has the due date actually passed?
    • Was the invoice delivered correctly — right email, right contact?
    • Has the customer already arranged payment that hasn't cleared yet?

    Sometimes a payment delay is simply an oversight. Confirming the details first prevents unnecessary awkwardness and protects your client relationship.

    Step 02

    Send a polite payment reminder

    The first reminder should always be professional, friendly, and non-confrontational. Most overdue invoices are paid after a simple nudge.

    Example reminder

    "Just a quick reminder that invoice #1023 for £2,100 was due on 14 March. Please let us know if payment has already been arranged. Happy to help if there are any questions."

    Keep the tone warm and collaborative. Reference the specific invoice number, amount, and due date so the customer can act immediately without searching for details.

    Step 03

    Follow up consistently

    Consistent follow-up is the single most important factor in recovering unpaid invoices. Most businesses fail to collect not because they can't — but because they stop chasing too early.

    Common reasons businesses fail to recover overdue invoices:

    • They send only one reminder and then wait
    • They forget to follow up after the initial message
    • They feel awkward about asking for money
    • They delay escalation hoping the customer will pay eventually

    A structured credit control process removes emotion from the equation. When follow-ups happen automatically on a set schedule, recovery rates increase dramatically.

    Step 04

    Escalate communication if necessary

    If polite reminders don't produce a response, your communication should gradually become firmer. This doesn't mean aggressive — it means clearer about consequences.

    Friendly reminder

    Polite nudge referencing the invoice

    Second reminder

    Professional follow-up noting the overdue status

    Firm reminder

    Clear request for immediate payment

    Final notice

    Formal notification of consequences if unpaid

    Payment plan discussion

    Offer structured repayment if unable to pay in full

    Each stage should be separated by a defined waiting period. The key is persistence — not aggression. Professional escalation protects your relationship while making clear that non-payment is not acceptable.

    Step 05

    Offer payment plans if customers cannot pay

    Sometimes customers genuinely cannot pay the full amount at once. Rather than writing off the debt or entering a dispute, offering a structured payment plan is often the most effective recovery strategy.

    Payment plans help you recover money that would otherwise become bad debt. They also maintain the client relationship and demonstrate flexibility — which can lead to future business.

    Example plan

    Invoice total: £4,200
    Payment plan: 3 monthly instalments of £1,400
    First payment due: 1 April

    Step 06

    Apply late payment interest (UK law)

    Under the Late Payment of Commercial Debts (Interest) Act 1998, UK businesses have the legal right to charge interest and compensation on overdue commercial invoices.

    Statutory interest

    8% plus the Bank of England base rate, calculated on the overdue amount from the due date.

    Fixed compensation

    £40 for debts up to £999.99, £70 for £1,000–£9,999.99, and £100 for debts of £10,000 or more.

    While many businesses choose not to enforce these charges on every invoice, making customers aware of the right to charge interest can encourage faster payment and demonstrate that your credit control process is serious.

    Step 07

    Use automation to manage credit control

    Manually chasing invoices works when you have a handful of customers. But as your business grows, it becomes impossible to maintain consistent follow-up across dozens or hundreds of invoices.

    Common problems with manual credit control:

    • Invoices fall through the cracks when staff are busy
    • Follow-up timing is inconsistent
    • There's no visibility into which invoices are at risk
    • Staff waste hours on repetitive admin instead of higher-value work

    Modern credit control software automates the entire process — sending reminders, escalating when needed, and giving you real-time visibility into your overdue invoices. This is where tools like AutoSettle make a transformative difference.
