Often with Cloud services, you do not have control over your information. When your business expands, it becomes more expensive to use these SaaS services. While it may have been cost efficient at the start-up of your company, it will become a barrier for you as you expand. A good alternative is open source software. Businesses small and large are taking advantage of the versatility of open source code.  Compared to SaaS Services, Open Source systems are cheaper, and they allow you to have more ownership over the critical software you use to run your company.
