Why Cashflow Is Everything
Cashflow is the lifeblood of every business. It does not matter how strong your order book is, how impressive your client list looks, or how profitable your contracts are on paper, if money is not flowing into your account when you need it, your business is in trouble.
The scale of the problem across the UK economy is stark. According to the Federation of Small Businesses, outstanding late and unpaid invoices owed to small businesses total approximately £23.4 billion at any given time. More critically, around 50,000 UK businesses close every year as a direct result of cashflow problems caused by late or non-payment.
These are not marginal businesses on the brink of failure for other reasons. Many are viable, growing companies that simply run out of cash because their customers do not pay on time.
The good news is that most cashflow problems are preventable. With the right systems, skills, and discipline, you can dramatically reduce the risk of late payment and keep cash moving through your business.
The Four Pillars of Cashflow Protection
Protecting your cashflow is not about any single action; it requires a structured approach across four key areas. Each reinforces the others, and together they form a robust defence against the cash drain of late and unpaid invoices.
1. Know Your Customer
The foundation of good credit control starts before you ever issue an invoice. Understanding who you are doing business with, their financial health, and their payment habits allows you to make informed decisions about the credit you extend.
Establish Legal Status
Before entering into any credit arrangement, confirm the legal status of your customer. Are they a limited company, a partnership, a sole trader, or an individual? This determines who is legally liable for payment and what recourse you have if they do not pay.
For limited companies, a quick check at Companies House reveals basic financial information, including filed accounts, directors, registered charges, and any insolvency events. For sole traders and partnerships, establishing personal liability is essential.
Use Credit Application Forms
A well-designed credit application form captures the information you need before extending credit. At a minimum, it should include:
- Full legal name and trading name of the customer.
- Registered address and principal trading address.
- Contact details for the person responsible for authorising and processing invoices.
- The customer’s invoice authorisation process: who approves invoices, what purchase order numbers are required, and what documentation they need to process payment.
- Trade references and bank details (where appropriate).
- Agreed payment terms, signed by an authorised representative.
This form is not just an administrative exercise. It establishes the commercial relationship on a clear footing and gives you the information you need to chase payment effectively if problems arise.
Conduct Risk Assessments
Not every customer presents the same level of risk. Some will pay promptly every time; others will need constant chasing. A simple risk assessment framework, based on the customer’s size, financial history, payment track record, and the value of the credit you are extending, helps you set appropriate credit limits and payment terms.
High-risk customers might warrant shorter payment terms, smaller credit limits, or even pro-forma payment until they have established a track record with you.
2. Credit Control Collection Training
Having the right systems in place is only half the equation. The people who actually make the calls, send the reminders, and negotiate with late-paying customers need the skills and confidence to do it effectively.
Collection Techniques
Effective credit control is a skill that can be taught and refined. It involves understanding the psychology of debt collection, knowing when to be firm and when to be flexible, and having a structured process for escalating overdue accounts.
Telephone Skills
Most debt collection happens over the phone, and the quality of those conversations determines whether you get paid. Effective telephone collection involves:
- Clear, confident communication of the amount owed and the payment deadline.
- Active listening to understand the debtor’s situation and identify genuine obstacles to payment.
- Structured call scripts that ensure consistency without sounding robotic.
- Knowing how to handle common stalling tactics and excuses.
Negotiation and Assertiveness
Collecting debts requires a balance of professionalism and assertiveness. You need to maintain the commercial relationship while making it absolutely clear that payment is expected and non-negotiable. This is a skill that improves with practice and training.
Ongoing Support
RCU offers post-training support through retainer arrangements, providing ongoing access to expert guidance as your team encounters real-world collection challenges. This means your credit control function continues to improve over time, rather than relying on a single training session.
3. Managing Cashflow Proactively
Beyond chasing individual invoices, managing cashflow effectively requires a broader view of your business finances and the systems that underpin them.
Cashflow Forecasting
A cashflow forecast is a forward-looking document that maps your expected income against your expected outgoings over a defined period, typically 13 weeks for operational planning, or 12 months for strategic planning. It highlights potential shortfalls before they become crises, giving you time to take action.
Good forecasting requires honest, realistic assumptions about when customers will actually pay, not when they are supposed to pay. If your average debtor days are 45, do not forecast income at 30 days.
Pricing for Cashflow
Your pricing strategy has a direct impact on cashflow. Consider whether your pricing structure includes sufficient margin to absorb the cost of late payment, and whether you can build in incentives for early payment or penalties for late payment (the Late Payment of Commercial Debts Act gives you statutory rights to charge interest on overdue invoices).
Supplier Negotiations
Managing cash out is just as important as managing cash in. Negotiate the longest reasonable payment terms with your suppliers, and take advantage of any early payment discounts they offer. The gap between when you receive payment and when you need to make payment is your cashflow buffer, and a wider buffer gives you more resilience.
The Killer Invoice
Your invoice itself plays a critical role in getting paid on time. A well-designed invoice is clear, professional, and contains everything the customer needs to process payment without delay. That means:
- A unique invoice number and clear date.
- The customer’s purchase order number (if required).
- A precise description of the goods or services supplied.
- The total amount due, broken down clearly.
- Your payment terms, prominently displayed.
- Your bank details for payment.
- The name and contact details of the person to call with any queries.
Invoices that are unclear, incomplete, or missing key information give customers an easy reason to delay payment. Do not give them that excuse.
4. Outsourcing Your Credit Control
For some businesses, particularly those without a dedicated accounts team, managing credit control in-house is simply not practical. The time and expertise required to chase invoices, manage disputes, and maintain a clean sales ledger can overwhelm small teams that already have too much on their plates.
Outsourcing your credit control function to specialist providers can be a cost-effective solution. A professional credit control service brings:
- Dedicated resources focused solely on collecting your money.
- Expertise in collection techniques and legal escalation.
- Consistent follow-up that prevents invoices from falling through the cracks.
- Professional detachment, as it is often easier for an external party to have firm conversations about payment.
RCU offers outsourced credit control support tailored to the needs of SMEs, from one-off ledger clean-ups to ongoing managed collection services.
Training Options
RCU provides credit control and cashflow protection training in several formats to suit different business needs:
- In-person training: Face-to-face sessions at your premises, tailored to your team and your business.
- Onsite workshops: Practical, hands-on workshops that include working with your actual ledger data and customer accounts.
- Online sessions: Remote training delivered via video conference, ideal for distributed teams or businesses with limited availability for in-person sessions.
- Retainer support: Ongoing access to RCU’s credit control experts for guidance, troubleshooting, and continuous improvement.
Taking Action
Cashflow problems rarely resolve themselves. The businesses that maintain healthy cashflow are the ones that invest in systems, skills, and discipline before problems arise, not after.
Whether you need to strengthen your credit application process, train your team in collection techniques, redesign your invoices, or outsource your entire credit control function, the goal is the same: get paid, on time, every time.
