It's not uncommon for entrepreneurs to use the terms “growth” and “scale” interchangeably when talking about adding revenue to their small business. The terms do have a similar meaning with a critical difference. 

Growing a business means that a business owner is adding revenue by adding more resources and higher costs to their operation. This could mean bringing on new clients and customers by adding a new location or building, purchasing new equipment or hiring more employees to meet the needs of those new clients.
