A profitable business can still run short of money. It happens when invoices are paid late, VAT falls due before customers settle their accounts, or a growing workload demands stock, staff or equipment before the income arrives. The best ways to improve cash flow are therefore not simply about spending less. They are about knowing what is due, when it is due and which decisions will protect your working capital.
For many owner-managed businesses, cash-flow pressure builds quietly. The bank balance may look healthy one week, then payroll, supplier payments and tax liabilities land together. With timely records and a practical plan, you can spot that pressure early and make choices from a position of control rather than urgency.
1. Build a rolling cash-flow forecast
A cash-flow forecast turns your expected sales, direct costs, overheads, loan repayments, payroll and tax liabilities into a forward-looking view of your bank position. It should show what is likely to happen weekly or monthly, not just what happened in the last set of accounts.
A 13-week forecast is often especially useful for businesses with regular trading cycles, while a 12-month view helps with wider plans such as recruitment, premises or investment. Neither needs to be complicated, but both must be based on realistic payment dates. An invoice issued in March is not March cash if the customer normally pays in May.
Update the forecast regularly and compare it with the actual bank balance. If there is a shortfall ahead, you have time to chase payments, defer a non-essential purchase, agree terms with a supplier or arrange suitable finance. A forecast is not a prediction carved in stone. It is a decision-making tool that improves as your information improves.
2. Invoice promptly and make payment easy
The longer it takes to raise an invoice, the longer it usually takes to be paid. Send invoices as soon as work is completed or as each agreed stage is reached. Include a clear description of the work, the due date, your bank details and the purchase order number where a customer requires one.
For larger jobs, consider requesting a deposit or billing in stages. Asking a business to fund several months of work before receiving any income can strain cash unnecessarily. Milestone billing shares that pressure more fairly, particularly in construction, consultancy, creative work and project-based services.
Make paying straightforward. Electronic payment details, card payment options where appropriate and clear invoice references reduce avoidable delays. It is also sensible to agree payment terms before work begins. A customer who expects 30 days should not discover a seven-day term only when the invoice arrives.
3. Follow up overdue debtors consistently
Chasing debts need not damage good client relationships. In many cases, an overdue invoice is the result of an internal approval delay, a missing purchase order or a simple oversight. A polite reminder before the due date, followed by a prompt call when payment becomes overdue, is usually more effective than leaving the matter until the balance has become significant.
Create a simple credit-control routine. Review aged debtors every week, allocate responsibility for follow-up and keep a record of conversations and promised payment dates. If a customer repeatedly pays late, reconsider the credit you extend to them. You may need payment upfront, a shorter billing cycle or a credit limit.
Be commercially sensible. A valuable customer experiencing a temporary difficulty may be worth accommodating through an agreed instalment plan. However, do not let goodwill turn into an open-ended source of finance for someone else’s business.
4. Review pricing, margins and customer profitability
More sales do not automatically mean more cash. If prices have not kept pace with wage increases, supplier costs, energy bills or additional delivery costs, every new sale may add pressure rather than relieve it.
Review your pricing at least annually, and more often if costs are moving quickly. Calculate the margin on your main products, services and contracts rather than relying on a broad average. Some customers may be profitable only because their true administration, delivery or rework costs have never been included.
A price increase can feel uncomfortable, but it may be the right step when it reflects the value you provide and protects service quality. Communicate it clearly, give appropriate notice and avoid apologising for running a sustainable business. It can also be more effective to stop offering an unprofitable service than to chase additional turnover to make up for it.
5. Manage stock and supplier terms carefully
Stock ties up cash until it is sold and paid for. Holding too little can lead to missed sales, but holding too much can leave money sitting on shelves and increase the risk of wastage or obsolescence. Review slow-moving lines, buying patterns and minimum order quantities. A modest reduction in surplus stock can release useful working capital.
Supplier terms deserve the same attention as customer terms. Pay suppliers on the agreed date, not automatically as soon as an invoice arrives, unless there is a worthwhile early-payment discount. Reliable communication matters here. If a payment will be late, speak to the supplier early rather than ignoring the invoice.
Try to match the timing of supplier payments to the cash you receive from customers. This will not always be possible, particularly for new businesses or specialist purchases, but even small improvements can smooth difficult periods.
6. Separate tax money from trading cash
VAT, PAYE, corporation tax and self-assessment liabilities can cause a sharp cash-flow shock when they have not been planned for. These amounts are not spare funds, even if they remain in the business bank account for several months.
Set aside a proportion of receipts into a separate savings account as you earn them. The appropriate amount depends on your structure, profitability, VAT position and payroll commitments, so it is worth calculating it rather than guessing. Keep tax dates in your forecast and allow for the fact that some liabilities may fall due during quieter trading periods.
Good bookkeeping makes this far easier. Up-to-date records show the VAT position, likely tax exposure and unpaid invoices before deadlines approach. They also give you better information when deciding whether a dividend, purchase or new hire is affordable.
7. Cut avoidable costs without cutting capability
Cost control is not about cancelling every subscription or choosing the cheapest supplier. The aim is to remove spending that no longer supports sales, service or efficient operations.
Review regular direct debits, software licences, insurance, phone contracts, vehicle costs and outsourced services. Ask whether each cost is used, whether it is still competitively priced and whether two systems are doing the same job. Small recurring amounts can become substantial over a year.
Take care not to cut costs that protect revenue or save staff time. Reducing bookkeeping support, for example, may appear to save money but can lead to late invoicing, poor debt collection and weaker decisions. Focus on value, not simply expenditure.
8. Use finance for the right purpose
Borrowing can be a sensible part of a cashflow plan, but it should fit the need. A short-term facility may help bridge a known gap between paying suppliers and collecting customer invoices. Asset finance may be more appropriate for equipment that will contribute to the business over several years.
Using long-term borrowing to cover repeated trading losses is different. It can postpone a difficult conversation about pricing, margins or overheads without fixing the cause. Before taking finance, model the repayments in your forecast and consider the impact if sales arrive later than expected.
Best ways to improve cash flow: make it a regular management habit
Cash flow improves when it is reviewed routinely, not only when the bank balance becomes uncomfortable. Set aside time each month to update your forecast, check overdue invoices, review upcoming tax payments and compare actual results with the plan. A short, disciplined review can prevent a much larger problem later.
For growing businesses, this is where an adviser can add real value. RK & Co helps business owners turn bookkeeping and accounts information into practical actions, from preparing cash-flow forecasts and budgets to identifying pressure on margins and planning tax liabilities. Clear figures give you the confidence to act sooner.
The next useful step is simple: look ahead at the next 90 days of money in and money out. Once you can see the pinch points, you can start making calm, informed choices that support the business you are working hard to build.
