For any business, customers are the number one priority. If we continue to look at customers as just a means of bringing in money, we are going to miss the opportunity to nurture a strong connection with them. Loyalty is more than a returning customer and multiple purchases: it’s the line between whether they will refer your company to their friends, engage with you on social media, and commit to advocating for you. No amount of money can buy a customer's trust.
I use to say, "marketing provides the forum for sales to occur". And that still rings true today, but what needs to be added to the bow is "marketing is responsible for revenue derived from inside sales platforms and anything digital or content driven".
