Scaling a business is harder than growing one

How to scale a business without breaking it: sort your systems, line up funding before you need it, and plan for the barriers that slow growing firms.

Winning more customers is rarely what stops a growing firm. What stops it is the spreadsheet that can no longer cope, the manager who becomes a bottleneck, or the cash gap that opens when you hire ahead of revenue. If you are working out how to scale a business, the order in which you fix things matters more than the speed at which you grow.

Sustaining growth is harder than starting it

A good year is not the same as a growth business. Between 2020 and 2023, 87,200 UK firms with 10 or more employees grew by more than 10% annually in either staff or turnover, but only around half of them (44,600) consistently met high-growth criteria. A large share of the firms that sped up could not hold the pace.

Picture a joinery firm that doubles its orders after landing a big contractor. Deliveries slip, the owner spends her days chasing snags, and two regular customers quietly go elsewhere. The sales result was real. The operating result was not.

The government’s own list of growth routes is a useful menu: sell more to existing and new customers, improve your products or services, hire or train staff, seek extra funding, sell online, and work with a business mentor. The mistake is trying all of them at once. Pick one or two, and make sure the business can carry the extra load before you add the next.

Get your house in order before you add volume

The British Business Bank’s how-to-scale checklist sets out five stages: understand your offering, get your house in order, refine your strategy, understand the aspects of growth, and seek help and advice. The second stage covers operations, financial systems and KPIs. It is the stage most owners want to skip, because it produces no new revenue.

In practice, it means three jobs. First, write down how your core work gets done, from enquiry to invoice, in plain steps that someone else could follow. If the process lives only in your head, every new hire will need you to explain it. Second, pick a handful of KPIs you can read weekly, such as sales, margin, cash in the bank and late deliveries. Third, make sure your bookkeeping gives you current figures, not last quarter’s.

That last point has a legal edge. GOV.UK states that once your VAT-taxable turnover exceeds £90,000, you must register for VAT. A fast-growing firm can cross that line sooner than the owner expects. If you only see your turnover at year end, you will find out late.

The trade-off is time. Tidying systems takes weeks of an owner’s attention that could go on selling. But the cost of doing it later is higher, because every customer and employee you add makes the mess harder to untangle.

Line up the money before you need it

Growth usually costs money before it makes money. The British Business Bank says scaling firms often need extra funding for expansion such as opening new locations, as well as for hiring, production, R&D, entering new markets and investing in technology. You pay for people and stock first, and the customers pay you later.

The same source lists the routes available: funding rounds known as Series A, B and C, grants, debt finance such as loans and overdrafts, and listing on AIM, the London market for smaller growing businesses. Most owners reading this will be choosing between debt, grants and perhaps outside investors, and each has a different price.

• Debt keeps you in control, but repayments are due whether or not the new sales arrive. An overdraft suits a short gap in cash, not a permanent new salary bill.
• Outside investment shares the risk, but you give up part of the business and some say in how it is run.
• Grants do not need repaying, but they take time and effort to apply for, so they rarely help with next month’s payroll.

The sensible habit is to talk to lenders or investors while the business is healthy, not when a growth plan has already stretched the bank balance. Work out what you would need if sales came in two months later than planned, and ask for enough to cover that.

The barriers that catch growing firms

Scale-ups report the same obstacles again and again. According to ScaleUp Institute data in the Department for Business and Trade’s evidence annex, the top barriers are access to UK and international markets (62%), talent and leadership development (54%), access to finance (47%), infrastructure and R&D (28%) and access to tax breaks (28%).

Markets come first. Reaching new customers is the barrier most firms cite, so treat it as a project with a budget, not a hope. Choose one new channel, region or customer type, set a small spend and a deadline, and judge it on the numbers.

Talent and leadership is a close second, and it is the one founders tend to underrate. As you grow, your job changes. You stop doing the work and start making sure others can do it well. That means training the people you have, and GOV.UK points to apprentices and mentors as routes. It also means deciding early which decisions you will hand over, and then actually handing them over. A founder who approves every quote becomes the ceiling on the firm’s output.

Finance appears in both this list and the previous section for a reason. Money problems rarely arrive alone. A hiring plan that outruns cash forces rushed borrowing, which narrows your options on everything else.

Use the ten dimensions as a quick audit

The British Business Bank’s ELITE Growth Compass framework breaks growth into ten dimensions: people, operations and processes, innovation, financial management and access to finance, digitalisation, growth strategy, risk management, market orientation, corporate governance and internationalisation. You do not need to be strong in all ten. The value is in seeing which one is weakest before growth exposes it.

Give yourself an hour with your senior team. Score each dimension honestly from one to five, then look at the lowest two. If the weak spots are people and operations, hiring more staff will make things worse. If the weak spot is financial management, a new site or product line is a risk you should not take yet. If you are weak on risk management, ask what happens if your biggest customer leaves or your best manager resigns.

Then ask for outside help. The checklist’s final stage is seeking advice, including mentorship and peer networks, and it is the cheapest of the five. Another owner who has grown a business through the same stage will spot problems that a spreadsheet will not.

Watch for the warning signs that growth is outrunning the business: late deliveries, rising complaints, cash that tightens as sales rise, and a diary that has no room for anything but firefighting. When two or more show up together, pause new sales, fix the cause and resume. A short pause costs far less than losing the customers you worked hardest to win.
