One of the key issues that concerns investors and management teams alike vis a vis the SaaS business model is its potential to consume a large amount of capital until finally reaching profitability. Many people have written about this topic, including me.
SaaS companies are typically built upon a stream of relatively low cost subscription licenses, paid out monthly/quarterly/annually — even multi-annually. Unfortunately, for the vendor, the subscription model usually generates far less up front cash than a traditional ‘perpetual license’ software model. But, over time, the compounding effect of the SaaS model can build into a nice annuitystream — provided churn rates are minimized.
It is this up front cash differential that is the primary appeal of the SaaS model over the traditional software model with customers. However, this differential is also what makes the model vexing for the SaaS management team and the investors.
