Cash flow is the lifeblood of any small business. It’s the money moving in and out of your business, and managing it well can mean the difference between success and failure. In the UK, cash flow challenges are common—over 57% of small business owners have faced problems, often due to late payments or poor cash management [1]. But with the right strategies, you can keep your finances healthy and your business thriving.

Tip 1: Be Clear on Payment Terms
Clear payment terms are essential for avoiding misunderstandings and ensuring timely payments. Always include your terms and conditions on invoices and contracts. For example, state that payment is due within 30 days and include a penalty, like a 2% interest charge per day overdue. This protects your business and sets clear expectations.
- Action Step: Review your current terms and update them if needed. Consider using a template for consistency.
- Why It Works: Clear terms reduce disputes and encourage customers to pay on time.

Tip 2: Invoice Promptly
Don’t delay sending invoices. The sooner you invoice, the sooner you can expect payment. Ask for a deposit before starting work and send the final invoice as soon as the job is done. Using accounting software can automate this process, saving you time and ensuring nothing slips through the cracks.
- Action Step: Set up automatic invoicing in your accounting system.
- Why It Works: Faster invoicing starts the payment clock sooner, improving cash flow.
Tip 3: Understand Your Customers’ Payment Processes
Knowing how your customers handle payments can speed up the process. Find out who approves payments, what documentation is needed, and any specific procedures they follow. This helps you avoid delays and ensures you’re prepared.
- Action Step: During onboarding, ask about their payment process and keep the details handy.
- Why It Works: Being proactive reduces friction and keeps cash flowing smoothly.
Tip 4: Protect Against Bad Debt
Bad debt can cripple your cash flow. Regularly credit-check your clients, especially new ones, to assess their ability to pay. Consider credit insurance to protect against non-payment, especially for larger contracts.
- Action Step: Use a credit-checking service for new clients and review existing ones annually.
- Why It Works: Early detection of risky clients helps you avoid cash flow headaches.
Tip 5: Chase Debtors Promptly
Don’t let invoices sit unpaid. Set up a system to follow up on overdue payments quickly. A polite phone call or email reminder can often prompt payment. If needed, consider using a debt collection service, but always aim to maintain good relationships with your clients.
- Action Step: Create a schedule for chasing overdue invoices, starting with a reminder at 7 days overdue.
- Why It Works: Timely follow-ups reduce the risk of payments becoming long-term issues.
Tip 6: Be Cautious with Extended Terms
Offering extended payment terms can help win business, but it ties up your cash. Only offer such terms if you’re confident in the client’s ability to pay and if it fits your cash flow needs. For repeat offenders, consider putting them on “stop” until they clear their dues.
- Action Step: Evaluate each request for extended terms carefully and set clear limits.
- Why It Works: Protecting your cash flow ensures you can cover expenses and invest in growth.
Tip 7: Plan for Tax Liabilities
Taxes can be a significant outflow, so plan ahead. Keep accurate records and set aside money regularly for VAT, corporation tax, or income tax. Consider opening a separate bank account for tax reserves to keep these funds secure.
- Action Step: Calculate your quarterly tax obligations and automate transfers to your tax account.
- Why It Works: Avoiding tax surprises keeps your cash flow steady.
Tip 8: Pay Suppliers on Time
Paying your suppliers on time builds trust and can lead to better terms or discounts. It also strengthens your reputation, which is crucial for small businesses. If you’re struggling, communicate openly with suppliers—they may be willing to work with you.
- Action Step: Prioritize supplier payments and negotiate longer terms if needed.
- Why It Works: Good supplier relationships ensure smooth operations and potential cost savings.
Tip 9: Build a Relationship with Your Bank
Your bank can be a valuable partner, especially during tough times. Keep them informed about your business’s financial health and discuss any seasonal or quiet periods. A strong relationship can make it easier to secure loans or overdrafts when needed.
- Action Step: Schedule regular check-ins with your bank manager.
- Why It Works: Banks are more likely to support businesses they understand and trust.
Tip 10: Consider Leasing Instead of Buying
Buying equipment ties up cash that could be used elsewhere. Leasing or renting can free up capital for other investments. Evaluate the total cost of ownership versus leasing to make the best decision for your business.
- Action Step: Compare leasing and buying options for your next equipment purchase.
- Why It Works: Leasing preserves cash for growth and reduces upfront costs.
