A business doesn't always need to be as big as it sounds. Every firm is not multi-national, and every enterprise doesn't sign multi-million dollar deals.
What is needed to be understood here is that any transaction, big or small can be researched and developed into a potent business idea. For example, a small catering business is also a business, or a decoration idea may also grow to become a small business with its own base of clients.
A small turnover is not necessarily negative - and it can always be expanded by finding like minded people who want to expand their horizons.
