Cash flow problems don't arrive without warning, and is just one of the growth problems scaling product businesses have to handle. In a scaling product business, they follow a pattern – and once you know the pattern, you can manage around it rather than react to it after the fact.
This isn't about cutting costs or slowing growth. It's about understanding where cash goes, when it comes back, and what to do in the gap.
💡 Key takeaways
Cash flow problems in product businesses are structural, not a sign of mismanagement – they're built into the model
The four main causes are inventory timing, payment terms, channel expansion, and poor financial visibility – and each one has a practical response
Managing cash flow well means making inventory and channel decisions as cash decisions first, not as growth decisions
The gap between paying out and getting paid doesn't shrink as you scale – it widens in absolute terms
Visibility is the foundation. You can't manage a cash position you can't see clearly.
Why cash flow gets harder as you scale, not easier
The assumption most founders make at some point: once we get big enough, the cash flow problem will sort itself out. More revenue, more cash coming in, more buffer.
It doesn't work like that. As orders grow, the cash tied up in inventory grows with them. As the customer base grows, the total value of outstanding receivables grows too. More retail accounts means more payment cycles running in parallel. The gap doesn't compress with scale – it widens in absolute terms, even if the proportion stays roughly constant.
Net working capital days in the UK have risen 48% since 2015, according to PwC's Working Capital Study 25/26 – and the picture is worse for smaller and mid-size firms, where NWC days have deteriorated by nearly 20% over the same period. Growth is consuming more working capital per pound of revenue than it did a decade ago.
This is the context. It's not just your business. It's the structure of the market.
The four main causes – and what to do about each one
1. Inventory timing
Every inventory order requires cash upfront – typically 50% before the goods leave the factory, with the balance on delivery. That cash is gone for weeks or months before it comes back as revenue. The larger the order, the longer the gap, and the more cash is sitting in a warehouse or in transit rather than in your account.
What to do: Treat every inventory decision as a cash flow decision before it's a buying decision. Before placing an order, model the cash position through to when that stock is expected to sell and payment is expected to clear. If the math doesn't work without external financing, that's useful to know before the invoice lands rather than after.
Seasonal pre-buys and bulk orders that unlock better unit economics are often the right call – but only if you've accounted for the cash commitment they represent. The decision isn't whether to buy in volume. It's whether you've planned for what that volume costs in cash terms.
2. Payment terms
Early in a brand's life, supplier terms are largely non-negotiable. Pay upfront or pay on delivery. On the customer side, wholesale buyers set their own terms – net 60 and net 90 are standard, and some retailers run longer. The result is a structural gap: cash goes out early, cash comes back late.
According to the FSB, late payments cost the UK economy £11 billion a year, with 38 businesses closing every day as a result. For product brands, even on-time payments at net 90 create a months-long gap that needs to be actively managed.
What to do: Work the gap from both ends. On the supplier side, push for better terms as your order volumes grow – net 30 instead of upfront, or extended terms on larger orders. It's slow progress, but each improvement compounds. On the customer side, model payment timing into every wholesale account before signing rather than discovering the cash impact after the first invoice goes out. And where the gap is unavoidable, finance it deliberately rather than reactively.
3. Channel expansion
Every new channel brings its own cash dynamics. Wholesale means net 60 or net 90 on top of inventory already committed. Amazon means stock sitting in fulfillment centers before it sells, with settlement cycles that don't align with supplier payment schedules. A new market means new logistics costs, import duties, and potentially new currency exposure.
The SKU problem compounds this. Each new product line requires its own minimum order quantity, its own reorder cycle, its own warehouse slot. Brands that grow their range faster than their sell-through data can justify end up with cash locked in slow-moving stock for months before it's written down or cleared through a promotion.
What to do: Evaluate new channels and new SKUs on cash terms, not just revenue terms. The question isn't just "does this channel work economically?" It's "what does this channel cost in working capital, and do we have it?" Brands that scale without repeatedly hitting cash walls tend to make this evaluation before committing, not after.
4. Financial visibility
This one is less obvious but compounds everything else. In a fast-growing product business, the financials are often out of date. Nobody had time to close the books. The last cash flow forecast was three months ago. The bank balance is what gets checked – and the bank balance, at any given moment, tells you almost nothing useful about actual financial health.
Cash might be stuck in transit stock that hasn't cleared customs. In invoices 45 days outstanding. In a new colorway that isn't moving as fast as projected. In supplier prepayments for an order eight weeks out. None of that is visible in the bank balance.
What to do: Monthly financials and a live cash flow forecast aren't good financial housekeeping – they're the minimum viable tool for making growth decisions that don't blow up later. If your books are consistently six weeks out of date, that's a structural problem worth fixing before the next inventory season, not after.
The visibility problem compounds everything
Inventory timing, payment terms, and channel expansion are all manageable if you can see them clearly. The difficulty is that growth makes visibility harder at exactly the moment you need it most.
The businesses that manage cash flow well through a scaling phase aren't necessarily better funded. They're better informed. They know where cash is sitting in the cycle at any given time. They model the gap before committing to new accounts or new channels. They treat financing as a planned tool rather than a last resort.
That's the practical difference between a business that scales cleanly and one that hits the same cash wall every six months – not luck, not more capital, but earlier visibility and deliberate planning around the gap.
Dan Major, a fractional CFO and recent guest on Treyd Secrets talks more about the visibility problem in this article on cash.
