Salesforce is the world's leading customer relationship management system (CRM), supporting thousands of businesses across the world, including a large chunk of the Fortune 500. Salesforce makes it significantly easier for businesses to connect with their customers, manage their operations, customize their sales workflows, and much more. However, because Salesforce is so customizable, it can also come with a bit of a learning curve. As such, many companies need Salesforce experts on staff to help them get the most out of the platform.
