306 invoices to reconcile, and counting. Every finance leader at month-end wonders ‘How can we increase productivity?’ and ‘When will this reconciliation finally be over? Meanwhile, the bank balance looks healthy but a major supplier payment is due tomorrow and two key customers haven't paid invoices which are now 60 days overdue.
Cash flow isn't just an accounting exercise. It's often the difference between seizing an opportunity and watching it pass. Between paying your team on time and scrambling for a short-term loan. According to UK Government figures, late payments cost the UK economy an estimated £11 billion annually, and government data indicates that approximately 38 businesses close every day as a result. Yet many finance teams still manage cash flow by checking the bank balance each morning.
Here is where Cash flow optimisation becomes a key part in treasury - also known as cash optimisation — it’s the process of accelerating cash inflows, controlling outflows strategically, and forecasting accurately enough to make confident decisions. It's not just about maximising profit on paper; it’s about having the liquid cash to cover obligations on time. A better cash position management enables your business to maintain operational stability while pursuing growth opportunities.
Why does this matter now? Survey data suggests that a significant proportion of finance professionals worry about the reliability of their cash flow data, and according to FreeAgent research, approximately 62% of invoices sent by SMEs are paid late. In an environment where collections are slowing and operational timing shifts faster than processes can keep up, even profitable businesses can hit a liquidity wall.
Against this backdrop, better cash flow management helps to identify the most viable investment opportunities for your business, weather downturns, negotiate better supplier terms, or simply sleep at night knowing payroll is covered. Companies that excel at optimising cash flow gain competitive advantages in banking, managing cash flow relationships, and strategic flexibility.
Cash flow is a key concern to any business, no matter the size, and difficulties in managing cash flow typically originate from two key issues:
Late payment is widely considered the single biggest cash flow killer for European SMEs. The Small Business Commissioner notes over 1.5 million companies face late payments annually, with roughly £26 billion tied up in overdue invoices at any given time. This research reveals nearly 14,000 small UK businesses close their doors annually due to delayed customer payments, equalling approximately 38 firms daily.
When clients delay paying, you might struggle settling your own supplier invoices punctually, possibly sparking a cascade crisis. Studies indicate that over a third of small businesses struggle to pay suppliers on time due to late receipts, with many admitting it even impacts payroll. The outcome? Strained business partnerships, costly panic borrowing, and endless hours wasted chasing down late payments. Without automated accounts receivable processes, these cash position management challenges compound over time.
According to a BlackLine survey, 98% of C-suite and finance professionals confirmed they do not have complete confidence in their organisation's view of cash flow. Evidence also suggests that many organisations still rely primarily on spreadsheets for cash flow forecasting, despite more sophisticated tools being available. The problem? Spreadsheets tend to be backward-looking, highly manual, and often out of date by the time decisions need to be made.
Without a rolling, regularly updated forecast, finance teams operate blind. They might not see pinch points coming, struggle to model the impact of new contracts, and ultimately resort to managing by intuition. Many finance teams reportedly spend a significant proportion of their time consolidating data from disparate sources instead of focusing on optimising cash flow. That's time that could be spent on strategic analysis, not data wrangling. Implementing dynamic forecasting is therefore a good practice for proactive cash position management.
While cash flow management is best done using professional software tools, there are a number of easy-to-implement operational measures that may help speed up your cash collection and reduce outlays:
A straightforward method to boost cash flow is getting paid faster. Issue invoices immediately upon completing the work, and ensure they are accurate and easy to pay. Provide multiple payment methods and create automatic reminders for late bills. Think about requesting deposits or milestone payments on bigger projects, and where profits allow, give small discounts for swift payment.
Evidence suggests this manual strategy or full AR automation works and firms can strengthen credit procedures with instant invoicing, transparent terms, and polite chasing. This typically leads to extra liquidity, helping eliminate their overdraft and resume owner compensation.
Central visibility across all payables allows treasury teams to prioritise payments strategically. Important: don't settle bills before required deadlines, and investigate extend payment periods where feasible without impacting supplier relationships.
Rank which invoices get priority using a centralised system that considers deadlines and consequences (wages, lease, vital vendors etc.). During temporary squeezes, your centralised accounts payable function can help adjust timelines with suppliers instead of skipping payments.
Live forecasting shifts cash management from passively reacting to actively leading. Compared to traditional spreadsheet methods, live forecasting merges real-time data from banks, accounting systems, and other systems to deliver constantly up-to-date liquidity views.
With this in place, you can generate a rolling 13-week forecast that updates automatically as transactions settle. Set alerts to signal when real cash flows differ from forecasts, enabling adjustments for emerging discrepancies. Live forecasting also typically includes scenario testing features, allowing treasury teams to stress test liquidity under different circumstances.
Inventory is one of the largest pools of trapped working capital for many businesses. Therefore, it’s critical to avoid tying up cash in excess stock. Approaches like ’just-in-time’ ordering or smaller, more frequent purchases are highly effective where supply risk is manageable. Repair rather than replace equipment where possible, and delay non-essential capital expenditures until cash flow is robust.

Managing cash across multiple bank accounts, entities, and currencies can create friction and poor visibility. Modern treasury platforms connect all your banks in real time through APIs and open banking, aiming to give you a single dashboard showing your true cash position. Organisations that implement unified treasury systems have reported faster decision-making and reductions in idle cash balances, though results may vary.
Centralisation may also simplify payment execution, reduce bank fees, and make cash pooling more efficient. Instead of logging into six bank portals each morning, you could potentially see everything in one place.
Tightened spend control is a key tool to improve cash flow. Review each expense and eliminate or reduce items that are not profitable, such as unused memberships, excessive utilities and unnecessary travel. Examine major fixed costs such as premises and staff, seeking better deals or flexible arrangements instead of fixed increases.
71% of organisations now employ AI in finance tasks, citing efficiency boosts and fewer mistakes in cash tracking and statements, according to KPMG's global AI in finance study. Current tools seek to combine data automatically, refresh predictions instantly as bank movements arrive, and spotlight lurking problems before disasters strike. In addition to this, findings from J.P. Morgan suggest machine learning can reduce error rates by up to 50%, as it analyses patterns, detects anomalies and accounts for business cycles. Treasury teams automating forecasts may spend less time on manual data entry and more on strategic decisions.
A single unified treasury system provides the technological foundation for effective cash management. Rather than juggling cash through scattered spreadsheets and manual work, one platform brings together all treasury tasks in one place as a ‘single source of truth’.
For seasonal companies, such a system enables you to plan around busy and quiet periods with clarity backed by numbers. Use past records in the unified system to chart busy versus quiet times, and then generate automatic monthly cash flow forecasts.
Here are two illustrative scenarios that demonstrate how this may work:
How a services firm unlocked cash flow by restructuring margins
Hypothetical situation: Imagine a small UK service company with strong sales who is under pressure because 58% of receivables are overdue by at least 45 days.
Potential approach: The business may choose to introduce weekly ageing reviews, same-day invoicing, daily reminders, appoint one dedicated owner for accounts receivable, and implement a delivery-proof checklist.
Likely outcome: Results may include improved collection from overdue customers, reduced Days Sales Outstanding and fewer disputes.
Hypothetical situation: In another example, a fashion boutique saw daily cash coming in but still hit a crunch because of over purchasing stock and heavy discounting.
Potential approach: They analyse product profitability, cut low margin lines, tighten buying to match realistic demand, reduce over-staffing, and scale back discounts.
Key insight: Cash flow problems in retail may sometimes be fixed by better margin management and leaner stock, not only more sales.
BlackLine research found that only 2% of C-suite and finance leaders reported full confidence in their cash flow visibility, and poor forecasting is often cited as the root cause. Other mistakes can include:
Modern treasury management systems aim to do more than replace spreadsheets; they automate bank connectivity, reconcile transactions in real time, and use AI to help predict and optimise cash flows with greater accuracy.

Cash flow optimisation is the practice of accelerating cash inflows, controlling outflows strategically, and forecasting accurately enough to make confident decisions without surprises.
Profit and cash aren't the same. You can be profitable on paper but cash-poor if customers pay late, you carry too much inventory, or you've invested heavily in fixed assets.
Approaches that may help include:
One widely recommended approach is to build a rolling 13-week forecast showing expected cash in and out week by week. Update regularly and use accounting software or a treasury system to automate data feeds.
A common guideline suggests two to three months' worth of operating expenses. Consider building it gradually during strong periods.
