Growth is seldom immediate in business, but you still need to invest in your business to attract customers or clients. Leverage is the practice of using money you get from another source, such as a line of credit from a bank, to buy the equipment – and merchandise, if you run a retail store – to operate your business. If you have cash on hand, leveraging your credit allows you to keep the cash in your bank account instead of spending it all. It also makes it possible to grow your business at a faster pace. For example, if you run a plumbing business, you can leverage your credit to buy two vehicles to reach more customers at a time instead of buying one vehicle and then saving up the cash to buy another one later.
