Reasons for business growth
Business growth involves a business increasing its size, scope or scale
Their leaders or owners may have ambitions for growth for a range of reasons
Reason | Explanation | Example |
|---|---|---|
Rising customer demand |
|
|
Economies of scale |
|
|
Entering new markets or products |
|
|
The challenges of growth
Growth brings clear benefits, but it can also create serious operational and financial problems if it is not carefully managed
As a business gets larger, it can benefit from lower costs through economies of scale
However, it also risks diseconomies of scale, synergy problems and overtrading
Diseconomies of scale
Diseconomies of scale occur when a company grows too large to manage and control effectively
This makes it harder to coordinate departments, manage the workforce or maintain quality, which raises the cost per unit
Further information on diseconomies of scale can be found here
Achieving synergy
Synergy is the extra value created when two businesses combine their resources so that the joint result is greater than the sum of what each could achieve alone
This comes either from lower costs (cost synergies) or higher sales (revenue synergies)
Synergies can be difficult to achieve in practice:
Cultural clashes
Synergy relies on people sharing ideas, data and resources
If two workforces have very different ways of working, projects may stall and expected savings may never materialise
Integration costs
Bringing systems, brands or supply chains together often costs more than expected
New IT links, staff training, redundancy payments and legal fees can spiral, reducing the savings or extra sales that were originally forecast
Overtrading
Overtrading happens when a business tries to grow faster than its working capital can support
For example by accepting more orders than it can manage, opening new sites through heavy borrowing, or acquiring other businesses without careful evaluation
Cash becomes tied up in inventory or unpaid invoices, while wages, suppliers and interest still have to be paid on time
This limits cash flow and can force a business to borrow at high cost, sell assets in a hurry or, in extreme cases, fail
Example
Carillion signed many large contracts with payment terms stretching beyond 120 days. The up-front costs on these projects drained cash faster than income arrived
The company went into liquidation in 2018 owing around £7 billion while holding only £29 million in cash
Examiner Tips and Tricks
When a case study business grows rapidly, always check whether its cash flow and working capital appear to be keeping pace. Recognising the early warning signs of overtrading rather than only identifying it once the business has already collapsed is a good analytical point
Methods of growth
Organic growth
Organic growth is growth driven by internal expansion using reinvested profits, owners' capital or loans
Organic growth is usually generated by
Gaining greater market share
Product diversification
Opening a new store
International expansion
Investing in new technology or production machinery

External growth
External (inorganic) growth is integration in the form of mergers, acquisitions or franchising
Methods of external growth
A merger occurs when two or more companies combine to form a new company
The original companies cease to exist and their assets and liabilities are transferred to the newly created entity
A takeover occurs when one company purchases another company, often against its will
The acquiring company buys a controlling stake (more than 50% of shares) in the target company's shares and gains control of its operations
Franchising is where a successful business lets other people open and run their own branches using its name, products and way of doing things
In return, franchisees pay an upfront fee and ongoing royalties, helping the original company grow quickly without having to invest all the money itself

Disadvantages of external growth
High cost
Acquisitions often need a large upfront payment, often funded through loans, increasing financial risk and straining cash flow
Integration difficulties
Combining different systems, brands and processes is often more complex and costly than expected, meaning synergies may not fully materialise
Cultural clashes
Differing management styles and cultures between the two businesses can cause conflict, lowering morale and productivity
Loss of control
Funding an acquisition through issuing new shares dilutes existing shareholders' ownership and control of the business
Risk of overpaying
Businesses often overestimate the value of, or likely benefits from, an acquisition target, leading to an inflated purchase price
Example
eBay paid $2.6 billion to acquire Skype in 2005, but failed to achieve the expected synergies with its online marketplace, and later sold Skype at a significant loss
Risk of losing key staff or customers
Uncertainty during a merger or acquisition can prompt skilled employees to leave or customers to switch to competitors before the change has settled
Sustainable growth
Sustainable growth means growing at a rate the business can support financially, operationally and culturally, while also considering its environmental and social impact
Choosing to grow sustainably often involves a trade-off between slower, steadier progress and the temptation to expand as quickly as possible
Advantages of growing sustainably
Reduces the risk of overtrading
Pacing a business's growth to match available finance and operational capacity helps avoid cash flow crises
Example
Riverford Organic Farmers has deliberately limited the pace of its expansion over the years, turning down opportunities for much faster growth in order to protect its quality standards and organic farming values
Protects long-term reputation
Growing in an environmentally and socially responsible way builds trust with sustainability-conscious consumers
This encourages customer loyalty and may mean a business can charge premium prices
Can improve access to finance
Investors increasingly favour businesses with strong environmental, social and governance credentials, which can lower the cost of borrowing
Supports employee retention
Steady, well-managed growth avoids the pressure that rapid, uncontrolled expansion can place on employees
This helps retain skilled staff and protect the company culture
Challenges of growing sustainably
Missed market opportunities
Growing more slowly and cautiously may allow less cautious competitors to capture market share first, particularly in fast-moving markets
Higher short-term costs
Sustainable materials, ethical supply chains and environmental technology often cost more than the cheapest available alternative
This can limit profit margins during a period of expansion
Difficulty in balancing competing goals
Environmental, social and financial objectives can conflict with one another
For example, maximising profit growth may not sit easily alongside meeting environmental targets, forcing a business to make difficult trade-offs
Requires strong leadership commitment
Shareholders sometimes push for faster short-term profits, which can push sustainable growth down the list of priorities
Risk of accusations of greenwashing
If a business claims to be growing sustainably without genuine evidence to support this, the resulting reputational damage can be worse than not making the claim at all
Example
H&M's Conscious Collection faced accusations of greenwashing, since the brand continued to grow the overall volume of fast fashion it produced while marketing a relatively small proportion of more sustainable products
The impact of growth on functional areas
Growth rarely affects only one part of a business
Decisions made to support expansion in one functional area often create knock-on requirements in the others
Functional area | Impact | Example |
|---|---|---|
Marketing |
|
|
Finance |
|
|
Human resources |
|
|
Operations |
