The Credit Control Process Explained: Practical Tips to Get Invoices Paid on Time

Late payments cost UK small businesses an estimated £22,000 per year on average, according to research by Xero. For many businesses, it is not the quality of their work that threatens their financial health. It is simply not getting paid on time for it.

If you have ever found yourself chasing the same invoice for the third time, wondering whether to push harder or soften your tone, you are not alone. Managing debts professionally, while protecting the client relationships you have worked hard to build, is one of the most common challenges I hear from business owners across the UK.

In this guide, I want to walk you through the credit control process from start to finish. Whether you are handling this in-house or thinking about getting support, these credit control tips will help you build a more robust, consistent approach to getting paid.

What Is the Credit Control Process?

The credit control process is the series of steps a business takes to manage the money it is owed. It covers everything from the moment you agree payment terms with a client through to the point where the invoice is settled.

A well-run credit control process does not begin when an invoice becomes overdue. It starts before the invoice is even raised. Effective credit control is preventative as much as it is reactive. It means setting clear expectations upfront, staying organised, communicating professionally, and escalating in a structured way when payments are not received on time.

Done well, the credit control process protects your cash flow, reduces the risk of bad debt, and preserves the professional relationships that keep your business growing.

Why Credit Control Matters for Your Cash Flow

Cash flow is the lifeblood of any business. You can have a healthy order book and a growing client base, and still find yourself unable to pay suppliers or staff if too much of your revenue is tied up in unpaid invoices.

According to UK Finance, late payment is one of the leading causes of small business insolvency in the UK. Yet many businesses treat credit control as an afterthought, something to deal with when things go wrong rather than a structured process embedded into day-to-day operations.

Here is why a proactive approach matters:

Overdue invoices accumulate quickly. One client paying 30 days late can disrupt your entire cash position.
Recovery rates decline over time. The older a debt becomes, the harder it is to collect. Debts over 90 days old have significantly lower recovery rates than those chased promptly.
Time spent chasing is time not spent growing. Many business owners underestimate how many hours per week they lose to informal, unstructured debt chasing.
Damaged relationships cost more than one invoice. Aggressive or inconsistent communication can end a business relationship that was otherwise valuable.

A structured credit control process addresses all of these risks. It keeps cash flowing, protects relationships, and removes the emotional stress of not knowing when you will be paid.

How to Set Clear Payment Terms From the Start

One of the most impactful credit control best practices is also one of the simplest: agree your payment terms clearly before you begin any work.

This sounds obvious, but a surprising number of businesses issue invoices without ever having explicitly confirmed the terms with the client. The result is confusion, dispute, and delay.

Here is what to get in writing before you start:

Payment due date. State whether terms are 14 days, 30 days, or another agreed period from invoice date or receipt of goods or services.
Accepted payment methods. BACS, bank transfer, card, or another method. The easier you make it to pay, the faster you get paid.
Late payment charges. Under the Late Payment of Commercial Debts (Interest) Act 1998, UK businesses are entitled to charge statutory interest on overdue commercial debts. Make your clients aware of this upfront.
Who to contact with queries. A named contact and email address for invoice queries removes friction and prevents "we have not received it" as a delaying tactic.
Dispute resolution process. Confirm how disputes will be handled and within what timeframe.

Including this information in your contract or terms and conditions, and sending a brief confirmation email at the start of every engagement, removes ambiguity and sets a professional tone from the outset.

The Steps of an Effective Credit Control Process

An effective credit control process follows a consistent, documented sequence. Here are the core steps to build into your approach:

1. Pre-work credit check (where appropriate)

For higher-value work or new clients, a basic credit check can flag risk early. Services such as Companies House, Creditsafe, or Experian Business can give you a picture of a company's payment history and financial stability.

2. Issue invoices promptly and accurately

Send invoices as soon as the work is completed or the milestone is reached. Delays in invoicing are often a leading cause of delays in payment. Ensure every invoice includes your company name, address, company number, invoice number, payment due date, and clear payment instructions.

3. Confirm receipt

A brief email or call to confirm the invoice has been received and is approved for payment is a small step that can prevent "we never got it" at the due date.

4. Pre-due date reminder

A short, friendly reminder three to five working days before the due date is courteous and effective. It keeps you front of mind and gives the client time to arrange payment without embarrassment.

5. First overdue contact

If payment has not arrived by the due date, make contact within one to two working days. Keep the tone professional and assume a positive reason first. A brief email referencing the invoice number, amount, and due date is usually sufficient at this stage.

6. Second contact and escalation

If there is no response or payment after a further five to seven working days, follow up again. This time, it is appropriate to request a confirmed payment date and ask whether there is any query holding up payment.

7. Formal notice

If the debt remains outstanding beyond a reasonable period, issue a formal written notice confirming the outstanding amount, any interest accrued, and the consequences of continued non-payment.

8. Legal escalation (where necessary)

In cases where all other steps have failed, legal action may be appropriate. This might involve a letter before action or a claim through the courts. Always take specialist advice before pursuing legal routes. Learn more about our debt recovery service.

How to Chase Overdue Invoices Without Damaging Relationships

This is, in my experience, the part that most business owners find most difficult. Nobody enjoys asking for money, and the fear of damaging a valuable client relationship often causes people to delay or soften their approach to the point where it becomes ineffective.

The good news is that professional, relationship-preserving debt chasing is absolutely achievable. It just requires the right approach.

Keep the tone neutral and factual. Avoid language that sounds accusatory or assumes bad faith. Most overdue invoices are the result of oversight, cash flow challenges on the client side, or internal approval delays, not deliberate avoidance.
Be consistent without being aggressive. A predictable, regular contact schedule is far more effective than sporadic, escalating pressure. When clients know you will follow up at consistent intervals, they are more likely to prioritise your invoice.
Separate the relationship from the invoice. You can acknowledge a strong working relationship and still expect to be paid on time. These two things are not in conflict. In fact, treating payment terms seriously is a sign of mutual professional respect.
Listen as well as communicate. If a client is in genuine difficulty, an early, open conversation about a payment plan is usually better for both parties than allowing the debt to age.
Document everything. Keep a record of every call, email, and agreement. If escalation becomes necessary, a clear paper trail protects you.

What to Include in a Credit Control Policy

A credit control policy is the internal document that sets out how your business manages debts. Having one, and making sure all relevant team members understand it, is one of the most effective ways to improve credit control across your organisation.

A good credit control policy should cover:

Credit limits and terms by client type. For example, new clients may be offered 14-day terms initially, with 30 days available once a payment history is established.
The contact schedule for overdue accounts. How many days post-due before first contact? What happens at 15 days? 30 days? 60 days?
Approved communication methods and tone. Email, phone, and letter templates that reflect your brand voice.
Escalation thresholds. At what point does an account move from standard chasing to formal notice, or from internal handling to external support?
Responsibility. Who in your business is responsible for each stage of the process?
Exceptions and disputes process. How are disputed invoices handled? Who has authority to agree a payment plan?

Reviewing your credit control policy at least annually, and updating it when your business model or client mix changes, keeps it relevant and effective.

Common Credit Control Mistakes to Avoid

Even businesses with good intentions can undermine their own credit control efforts. Here are some of the most common mistakes I see, and how to address them:

Waiting too long to follow up. Leaving overdue invoices for two or three weeks before making contact significantly reduces recovery rates. Act within one to two working days of a missed due date.
Inconsistent follow-up. Chasing once and then going quiet sends the wrong signal. Stick to your contact schedule regardless of how awkward it feels.
Mixing the relationship with the invoice. A strong working relationship does not mean accepting late payment. Separating these two things professionally is a skill worth developing.
Not having clear terms in place. If your payment terms are buried in an email footer or never explicitly confirmed, you have less ground to stand on if a client disputes them.
Treating all debtors the same. A long-standing client who has never missed a payment before deserves a different initial approach to a newer client with a history of delays. Context matters.
Failing to document communications. Without a clear record of what was said and agreed, you have no evidence base if a dispute arises or escalation becomes necessary.
Writing off bad debt too quickly. Bad debt prevention starts early. Many debts that feel unrecoverable can still be collected with the right approach, particularly those under 90 days old.

When to Consider Outsourcing Credit Control

There comes a point for many businesses where managing credit control in-house is no longer sustainable. This might be because the team is growing and the admin burden is increasing, because outstanding invoices are beginning to affect cash flow in a meaningful way, or simply because chasing money is taking time and energy away from the work you are actually good at.

Outsourcing credit control does not mean handing over control of your client relationships. At KS Credit Control, our service is entirely white-label: we work under your brand name, using your tone of voice, as a seamless extension of your team. Your clients never know they are speaking to anyone other than your own business.

Our clients come to us at different stages. Some engage us before they have a backlog, to put a proactive structure in place. Others come to us with an aged ledger they want to recover from. Either way, our approach is the same: professional, relationship-focused, and results-led.

We work on a flat monthly fee for ongoing outsourced credit control, or on a no collect, no fee basis for debt recovery. There are no upfront costs on the collect-out service. If we do not recover anything, you do not pay anything. Learn more about our collect-out service.

Frequently Asked Questions

What is the credit control process?

The credit control process is the structured approach a business uses to manage the money it is owed. It begins with setting clear payment terms and issuing accurate invoices, and follows a defined sequence of communication steps to ensure invoices are paid on time. It covers both preventative measures, such as credit checks and clear terms, and reactive steps, such as chasing overdue accounts and escalating to formal action where necessary.

How do I improve my credit control?

Start with the basics: ensure your payment terms are agreed in writing before work begins, issue invoices promptly, and confirm receipt. Then build a consistent follow-up schedule so overdue invoices are chased quickly and regularly. Introducing a written credit control policy, and ensuring everyone in your team understands it, makes a significant difference. If in-house capacity is a barrier, outsourcing to a specialist can help you implement a professional process without adding headcount.

What are credit control best practices?

Credit control best practices include: agreeing payment terms upfront and in writing, issuing accurate invoices without delay, following a consistent and documented contact schedule for overdue accounts, keeping communication professional and factual at all times, recording all contact and agreements, and reviewing your approach regularly. Prevention is more effective than cure. The earlier you act on an overdue invoice, the higher the likelihood of recovery.

When should I outsource credit control?

Consider outsourcing when the time spent chasing invoices is taking you away from running your business, when your aged debt is growing and internal efforts are not keeping pace, or when you want to bring professional structure to your credit control without hiring additional staff. Outsourcing is also worth considering if you are concerned about the impact that chasing has on your client relationships. A specialist can handle the process professionally and under your brand name, protecting both your cash flow and your reputation.

What is the difference between credit control and debt recovery?

Credit control is the proactive and ongoing management of outstanding invoices, typically covering the period from invoice issue through to payment. It is designed to prevent debt from occurring or escalating. Debt recovery refers to the process of collecting money that is already significantly overdue, often where standard credit control steps have not resulted in payment. The two services are complementary. At KS Credit Control, we offer both under one roof, so clients can manage their ledger proactively and escalate individual debts when needed.
