There’s a version of this question every founder eventually asks. Usually after a big order lands, or just before a seasonal push, or when the bank balance looks thinner than it should. Should I finance this – or just use what we have? It sounds like a simple decision. It rarely is. The answer depends on what the cash is actually for, what it costs to have it sitting idle, and what you’re giving up by not deploying it elsewhere. This guide gives you a clear framework for thinking it through.
💡Key takeaways
Using your own cash isn’t free – it has an opportunity cost that rarely shows up as a line item
Financing makes most sense when the return on the capital exceeds the cost of borrowing it
Cash reserves are best kept for genuine uncertainty – not to fund predictable, recurring costs
The right question isn’t “can I afford to finance this?” – it’s “can I afford not to?”
Most growing product businesses reach a point where self-funding becomes the more expensive option
What’s the hidden cost of using your own cash?
Self-funding feels safe. No debt, no interest, no external parties. But it carries a cost that most founders underestimate – because it never appears on a P&L.
When you tie £100,000 of your own cash up in a production run for 90 days, that money isn’t available for anything else during that window. A marketing push you could have run. A bulk production opportunity that would have dropped your unit cost by 15%. A second product line you’ve been holding off on. An unexpected opportunity that needed a fast response.
That’s not a theoretical cost. That’s a real constraint on what your business can do – and it compounds as order sizes grow.
The question to ask isn’t “what does financing cost?” It’s “what does tying up my cash cost?” Once you frame it that way, the calculation often looks different.
When financing makes sense
Financing earns its place when the return on the capital clearly exceeds the cost of accessing it. For product businesses, that calculation usually tilts toward financing in these situations:
The order is larger than your cash cycle can comfortably support. If fulfilling this order means your reserves drop to a level that makes you uncomfortable – or means you can’t fund the next cycle – that’s a signal. You’re not being prudent by self-funding. You’re creating a fragility you don’t need to.
The opportunity is time-sensitive. A bulk production run at a price that won’t last. A new retail listing that needs stock in six weeks. A seasonal window that opens once a year. When timing matters, the cost of waiting for cash to cycle back is often higher than the cost of a financing facility.
The cash cycle is long and predictable. If you reliably know that cash goes out in January and comes back in May, that’s not uncertainty – that’s a structural gap. Structural gaps have structural solutions. Financing that gap costs a fraction of what it costs to constrain your business around it every cycle.
You’re growing fast enough that each cycle requires more capital than the last. Growth consumes cash. The faster you grow, the more capital is sitting in your operating cycle at any given time. Brands that try to self-fund aggressive growth often find themselves choosing between the next order and keeping the lights on. That’s not a cash flow problem – it’s a working capital problem, and it has a better solution than slowing down.
The return on the capital is clear. You know what this order is worth. You know your margin. If the gross profit on the order significantly exceeds the financing cost – which, for most product businesses at scale, it does – the math is straightforward.
When using your own cash makes sense
Financing isn’t always the right answer. There are situations where deploying your own capital is the smarter move.
The cash cycle is short and the amount is small. If the order pays back in 30 days and the sum is comfortably within your reserves, the friction of a financing facility may not be worth it. Not every order needs external capital.
You have a financing facility in place but the cost doesn’t justify this specific use. Good financing is a tool, not a default. If the margin on a particular order is thin and the cycle is short, it might not clear the bar.
You’re in a genuine period of uncertainty. Cash reserves exist to absorb shocks – a delayed shipment, a customer paying late, an unexpected cost. If your reserves are already stretched and the environment feels unpredictable, preserving liquidity can be the right call even if the numbers on the order look good.
The growth is genuinely discretionary. Not all growth is urgent. If you’re considering a new product line or market entry that could wait six months, the case for using your own cash – or saving up for it – is stronger than for a time-sensitive production run.
A simple framework
Before deciding, run through these four questions:
What does this capital enable – and what’s the return? If the margin on the order or initiative significantly exceeds the financing cost, the math usually favors financing.
What’s the opportunity cost of tying up my own cash? What could that capital do elsewhere in the business during the same window? If the answer is “nothing urgent,” self-funding looks more sensible. If the answer is “quite a lot,” that changes the calculation.
Is this a predictable, recurring need – or a one-off? Predictable gaps deserve structured solutions. Financing a gap you’ll hit every cycle is more efficient than manually managing it each time.
What’s my buffer? If financing this means your reserves drop to a level that would make a sudden disruption genuinely damaging, that’s a flag. Financing should expand your options – not remove your safety net.
The stage at which this usually shifts
For most product businesses, the inflection point comes somewhere around the £1M revenue mark. Below that, the cash gaps are usually small enough to manage on reserves. Above it, the cycle starts to consume more capital than most businesses have sitting idle – and the opportunity cost of self-funding starts to show up in decisions you’re not making. That’s the moment when financing stops being a sign of financial weakness and starts being a sign of financial maturity. The brands that make the switch early tend to grow faster – not because they’re taking more risk, but because they’ve stopped letting their working capital structure cap their ambition.
Summary
Using your own cash isn’t free, and financing isn’t inherently risky. The right answer depends on what the capital is for, what it costs to tie it up, and what you’d do with it otherwise. For predictable, recurring gaps – the kind that come with every production cycle – financing is almost always the more efficient tool. For short cycles with thin margins and no competing use for the cash, self-funding makes more sense. The goal isn’t to avoid debt. It’s to deploy capital – yours and others’ – in the way that best supports the business at the pace you actually want to grow.
