Selling features and scaling sales is not a sustainable profit model
Stop selling features; become the indispensable business partner for your highest paying customers.
Selling features is a race to the bottom. You drain your company and struggle to deliver added value; you become replaceable.
More sales, like a never-ending caterpillar.
Profit does come from sales, but it's hardly scalable and only works temporarily. Soon, another cash injection is needed to maintain profit levels.
Starting to sell without first marketing your strategic advantage? That will cost you more time, money, and expansion frustration in the long term.
