You can have the sharpest product in your sector and still run out of road within eighteen months. It happens more often than founders like to admit, and it rarely comes down to the idea itself.
It comes down to what’s happening in the bank account while everyone’s attention is on growth.
1. Cash flow decides who’s still trading in five years
Profit and cash are not the same thing, and mixing them up is one of the fastest ways to kill a business that’s actually doing fine on paper.
Of the UK businesses that opened in 2019, only 38.4% were still trading five years later, according to ONS figures published last November. That’s not because the founders lacked ambition. Plenty of them were selling well and still ran short of the cash needed to pay suppliers, staff or HMRC on time.
2. Know your numbers before an investor does
If someone asks about your gross margin, your customer acquisition cost, or your monthly burn rate and you have to go and check, you’ve already lost some credibility in that room. You don’t need to be a qualified accountant.
You do need to know, without looking it up, roughly how many months of runway you have left and what’s driving your biggest costs. Investors ask these questions early precisely because founders who can’t answer them tend to be the ones surprised by their own numbers a few months later.
3. Late payments will eat your runway quietly
This one catches out even well-run start-ups. Research commissioned by the Department for Business and Trade found that late payments cost the UK economy around £11 billion a year and are a factor in roughly 14,000 business closures annually.
If a client pays you 45 days late, that’s 45 days you’re financing their business instead of building yours. Chase invoices the week they fall overdue. Don’t wait a month out of politeness.
That gov.uk press release is a live, permanent GOV.UK page (not a query-string CMS link), so it should resolve properly. Swap that paragraph in for the old point 3 and the rest of the article stays as is.
4. Get the boring stuff off your plate early
Bookkeeping, payroll, VAT returns, year-end accounts. None of it is exciting, and all of it eats the hours you should be spending on customers and products.
This is where a lot of early-stage founders bring in specialist support rather than muddling through with a spreadsheet and good intentions. Startup Accountancy, for instance, works specifically with early-stage and growing businesses on fixed-fee monthly packages, which makes budgeting for it far simpler than an unpredictable hourly bill.
5. Forecast forward, don’t just report backward
A set of accounts tells you what already happened. A forecast tells you what’s coming, and gives you time to react.
Rebuild your cash flow forecast monthly, even roughly, and stress-test it against a slower sales month or a late-paying client. Founders who do this tend to spot trouble six or eight weeks before it becomes a genuine problem, which is usually enough time to fix it.
