One of the hardest parts of working with SME clients is this: by the time they call you in a panic about cash, the problem is usually 3 to 6 months old. The warning signs were there. They just were not visible to anyone who was actually looking.
This is not a failure of the business owner. Most SME owners are not watching their financials closely enough on a regular basis or weekly basis to catch subtle deterioration early.
Here are seven warning signs that a small business client is heading toward a cash crisis. These are the signals worth building into your regular client review process.
1. Accounts Receivable Days Are Increasing Month on Month
Debtors getting slower is one of the earliest and most reliable indicators that cash flow trouble is building. When a client’s average debtor days stretch from 35 to 45 to 55 over a few months, it means customers are paying later, the client is less confident chasing payment, or the customer base is under its own financial stress.
In isolation, a single month of longer debtor days is not a crisis. As a trend over three or four months, it is a serious warning. The longer invoices sit unpaid, the wider the gap between revenue on the profit and loss and cash actually available.
Watch the receivables ledger carefully. Any client with receivables ageing beyond 60 days on more than 20 percent of their book warrants a direct conversation before the situation deteriorates further.
2. The Gap Between Profit and Cash Is Widening
A profitable business running out of cash is not unusual. It is, in fact, one of the most common ways SMEs get into serious trouble. The profit and loss says the business is doing well. The bank account says something different.
This disconnect happens for several reasons: rapid growth consuming cash faster than it is generated, stock building up in inventory, extended debtor terms, or significant capital expenditure not reflected in the operating profit number. When you see this pattern, the business is consuming more cash than the profit number suggests, and the trend is unsustainable.
Tracking the reconciliation between net profit and net cash movement is a discipline that catches this early. A widening gap between these two numbers is a red flag that demands explanation.
3. The Business Is Using Its Overdraft as a Standard Operating Tool
Overdrafts are designed for short-term smoothing of cash flow, not as a permanent feature of the operating cash position. When a client starts treating the overdraft as routine and the balance is fully drawn at the end of most months, it means their normal operations are consistently consuming more cash than their collections generate.
If the overdraft is fully drawn every month and the business is not in an intentional growth or investment phase that explains this, the underlying cash model is broken. The overdraft is masking it temporarily. When the overdraft limit is reached and there is no further headroom, the business has nowhere left to go.
4. Payables Are Being Stretched Without a Clear Strategy
If you notice that a client is consistently taking longer to pay their suppliers, and there is no deliberate working capital strategy behind it, this is worth investigating. Stretching payables is often the last line of defence before a business runs out of cash options.
It is also a sign of a deteriorating supplier relationship. Suppliers who are paid consistently late will eventually stop extending credit, change their terms, demand prepayment, or deprioritise the client in ways that affect the business operationally. When this happens, the downstream cash impact compounds the original problem.
The distinction to make here is between deliberate payment timing as part of a working capital strategy, and stretching payables out of necessity. The first is a CFO-level decision. The second is a warning sign.
5. Revenue Is Lumpy but Expenses Are Fixed
Some business models have inherently uneven revenue: construction, agencies, project-based professional services, seasonal retail. When the revenue cycle is lumpy and the expense base is fixed, cash flow is structurally vulnerable around the gaps between payments.
A client who lands a large contract and spends up on staff and equipment before the payment schedule catches up is a classic version of this risk. They may be genuinely profitable and genuinely growing. But the timing mismatch between when they spend and when they collect can create a cash gap that catches them by surprise.
Monitoring the forward cash position for these clients requires more active forecasting, not just historical review. If you are not running 90-day rolling forecasts for project-based clients, this is the warning sign that tells you to start.
6. Inventory Is Growing Faster Than Sales
For product businesses, inventory is cash. Every dollar tied up in stock sitting on a shelf is a dollar not available to pay wages, rent, or creditors. When inventory starts growing faster than sales, the cash conversion cycle lengthens and cash availability shrinks, even if the profit and loss looks fine.
Look at the inventory turnover ratio and compare it to prior periods and to industry benchmarks where available. Slowing turnover in a business that is also showing stretched payables and slower debtor collections is a combination that signals serious stress ahead. These three signals together are rarely a coincidence.
7. The Owner Goes Quiet
This one is informal, but experienced accountants and advisors know it to be true. When an engaged client starts going quiet, delaying conversations, or becomes vague when you do talk about their financials, it almost always signals that they know something is wrong and are not ready to face it.
This avoidance behaviour is human and understandable. Running a business is emotionally as well as financially demanding, and when the numbers are bad, the instinct is sometimes to stop looking at them. But it is exactly when the most damage is done, because decisions get delayed and options close off.
A proactive advisor who reaches out first, with a clear picture of what the data is showing, gives the client a reason to engage rather than avoid. You are not the bad news. You are the person who helps them navigate through it before the situation becomes critical.
Building a Monitoring System That Catches These Signals Early
The challenge with these seven signals is that catching them consistently across a client portfolio requires a system. Manually reviewing every client’s financials deeply enough to spot trends across receivables, payables, inventory, and cash conversion is not realistic when you are managing 40 or 60 or 100s SME clients.
This is where platforms like Finoya add genuine value to an accounting or advisory practice. When a client’s accounting data is connected to the platform, it monitors these indicators automatically and surfaces clients whose metrics are moving in the wrong direction. You see the warning early, before the client feels it, and before the options narrow.
The conversation with a client you alert three months before a crisis is very different from the conversation you have when they call you in a panic. In the first, you are a trusted strategic advisor. In the second, you are managing damage.
Most of the clients who experience a serious cash crisis say the same thing afterward: the signs were there. Someone just needed to be watching. Building that monitoring into your practice is not complicated. It is a decision to be proactive rather than reactive, and to use the right tools to make that sustainable at scale.
