When I was growing up, they had a saying in business. There’s the product you market, the product you sell, and the product that makes money. The example was McDonalds which marketed the Big Mac. When you bought a meal they would ask “want some fries with that?” They made almost all of their profit off the coke drinks. At the time it was rumored to be around 90% profit margin.
In today’s business you need three products:
The product you market – your brand, your mantra, your flagship product that everyone wants.
The product that generates cash—this is basically a service business that pays the bills now.
The product you build to sell as a business unit later–this is typically a SaaS business model that provides recurring revenue.
It can be hard to build a SaaS business when the only thing you are building/selling is the SaaS product. Consider adding more products around it to make the business easier to grow.
