When you eliminate any one from your business, the others begin to fall apart.

Before you invest in marketing strategies to promote your business, you must first make sure that you have a proven sales system in place to support leads and convert them into paying customers. 

On the flip side, before your salespeople are ready to meet with prospects, you should make sure your branding, website, and marketing materials are consistent, well-designed, and get your message across in a way that speaks to your customers.
