It’s a frustrating position: sales are rising, the pipeline looks strong, and the business appears profitable – but you still feel like you’re constantly “chasing cash.”
This usually happens when money is trapped in working capital. That means cash is sitting in invoices, stock, project costs, or slow customer payments instead of sitting in your bank account.
And it is not rare. UK research shows late payments affect around 1.5 million businesses each year, with £26 billion owed in late payments at any given time. On average, affected businesses are owed around £17,000.
The good news is that working capital is one of the most fixable problems in corporate finance – once you can see what is actually happening.
The working capital trap
Working capital is the gap between:
- Money going out (wages, suppliers, rent, tax, delivery costs), and
- Money coming in (customer payments)
When that gap grows, the business starts funding customers, projects, or stock – and the pressure lands on you.
A common pattern looks like this:
- You win more work
- You deliver more work
- You invoice more
- You wait longer to get paid
- Your costs rise immediately, but your cash arrives later
Late payment is a major driver of this pressure. FSB reporting shows over half of small businesses experience late payments, and many report it is getting worse.
The warning signs you should not ignore
If you recognise two or more of these, working capital is likely the real issue:
- You are profitable, but the bank balance does not reflect it
- You are always “one big invoice away” from feeling comfortable
- You are stretching supplier payments to buy time
- You are using tax money or VAT money to cover operating costs
- You keep delaying hires, equipment, or marketing because cash feels too tight
- You have strong sales growth but growing stress behind the scenes
These signs matter because cashflow pressure is not just uncomfortable – it can become existential. UK research estimates 14,000 businesses close each year because of late payments, which is roughly 38 businesses every day.
Why this happens – the 6 most common causes
In most growing businesses, cash tightness comes from predictable drivers:
1) Your payment terms are longer than your supplier terms.
You might pay suppliers in 7-30 days but get paid by customers in 30-90 days. The gap is funded by you.
2) Your invoicing is not fast or tight enough.
If you invoice late, invoice inaccurately, or allow disputes to drag, cash slips quietly.
3) You are growing stock or project costs faster than cash.
More growth often means more inventory, more labour, and more delivery cost before invoices are paid.
4) Your customers pay slowly because there is no consequence.
Many businesses accept slow payment as “normal,” but it becomes the business model of your customer – funded by your balance sheet.
5) You are under-pricing the real cost to deliver.
Margins look fine until volume exposes the truth: delivery cost rises, and cash drains faster.
6) Your forecasting is not giving you early warning.
Without a rolling 13 week cash forecast, you only spot the problem when it is already painful.
The quick working capital diagnostic
Here are the questions that reveal what is really happening:
What is your average time to get paid (DSO)?
- What is your average time to pay suppliers (DPO)?
- How much cash is currently tied up in unpaid invoices?
- How much cash is currently tied up in stock or work-in-progress?
- Which 10 customers pay slowest, and what does that cost you monthly?
- How many invoices are disputed, and why?
- What happens to cash if sales grow 20% next quarter?
- What happens to cash if sales drop 10% next quarter?
If you cannot answer these clearly, the business is likely being run on profit numbers while cash runs on guesswork.
What to do next
Working capital improves when you act on three levers: receivables, payables, and stock/WIP.
1) Fix receivables
- You should invoice immediately when milestones are met
- You should use clear purchase orders and acceptance criteria to reduce disputes
- You should chase early, not late, with a structured follow-up rhythm
- You should tighten credit control on repeat slow payers
- You should renegotiate terms when you have leverage, not when you are desperate
2) Stabilise payables
- You should map supplier terms and prioritise strategic suppliers
- You should negotiate terms as part of a professional finance plan, not as a last minute request
- You should align supplier payment timing to customer payment timing where possible
3) Reduce stock and WIP drag
- You should identify slow-moving stock and convert it into cash where sensible
- You should tighten purchasing so stock growth matches real demand
- You should track work-in-progress and ensure you bill promptly for delivered value
4) Use the right funding tools
Sometimes the business is doing the right things operationally – but cash timing still causes strain. That is when finance structures can help.
Invoice finance and asset-based lending are commonly used to unlock working capital and support growth, especially where invoices are strong but payment timing is slow.
The key is choosing the right structure for your model, margins, and customer base – so finance supports growth instead of creating hidden friction.
The big mindset shift: stop managing “profit” and start managing cash intent
A growing business can fail while still “winning work” if cash is unmanaged.
The strongest operators run the business on:
- A clear cash conversion view
- A rolling short term cash forecast
- Tight invoicing and credit control
- Funding structures that match their real cash cycle
When you do that, growth becomes calmer. Decisions become easier. And the business starts to feel like it is working for you again.
A simple next step
If cash feels tight despite growth, the best first step is clarity.
A good first conversation usually answers:
- Where cash is trapped.
- What fixes are quickest.
- What funding routes (if any) are suitable.
- What the next 30-90 days should look like.
