When you’re building a business, your reputation is all you have. While flashy marketing campaigns or persuasive sales materials can help you close a deal, they’re not going to be strong enough to keep your customers coming back to purchase again.

As an entrepreneur, it can be difficult to separate these two ideas. If you’re putting all your energy into attracting new customers, you might forget to give a customer who has purchased from you your best work.

Unfortunately, if the customer isn’t happy with what you’ve done for them, they’ll not only move on to a competitor, but they might tell their friends, family, co-workers and acquaintances about their bad experience. If that happens too often, you develop a bad reputation — the kiss of death in the business world.
