Once your business reaches a certain size, you may have to explore new options to continue growing, like franchising or international export. Growth can have many benefits, like economies of scale, more control over your market, and more long-term stability.
Growth means changing how you do business: new technology, more employees, less centralized control, and likely the need for more money. Make sure you have a solid plan and be ready to adapt to constant change.
