International expansion is an exciting time for any business in its growth lifecycle.
It is imperative, however, that businesses are aware of all the obligations and pitfalls that go alongside that expansion, with professional expertise and experience often being essential. Here, we will highlight the main benefits of expanding internationally whilst touching on some key considerations. Our team are a seasoned International Tax team, and are well placed to assist with each of these aspects.
Perhaps the most obvious aspect of international expansion is the opportunity to access entirely new markets and untapped client bases for immediate, significant growth.
Penetrating new markets can provide businesses with key competitive advantages, from being first to establish a foothold and build brand awareness to gaining greater autonomy and control over third-party supply chains.
That heightened sense of identity can instil familiarity and trust in your customer base, whilst also signalling positive growth prospects and intent from an investor perspective.
Like businesses, the world’s leading talent pool is spread internationally, and individual circumstances often lead talent to seek to travel and rehome elsewhere.
Expanding internationally can allow businesses to tap into that talent pool and offer solutions such as remote working that they otherwise would not have been able to. The most successful businesses often begin with the people driving them behind the scenes, with international expansion providing a route to an array of experiences, expertise, and cultures that would otherwise have been foregone.
Volume is often followed by more favourable terms, whilst many territories may have more affordable working alternatives than the one your business is currently in. Expansion allows businesses to tap into those territories and strategically plan how best to structure their operations, as well as providing much greater bargaining power when negotiating with suppliers and customers alike.
International expansion can build resilience against economic market uncertainty and change, thereby fostering a more stable outlook for the future.
By diversifying the markets they operate in, businesses can spread risk across multiple territories and markets, so if one suffers from a domestic economic downturn or political uncertainty, the slack created can be supplemented by better prospects in other markets, rendering the initial downturn less material. Like any portfolio, a diverse strategy
equates to the most robust and prosperous in the long term.
