IDC research says that by the close of 2016, SMBs (under 500 employees) will have collectively spent $564 Billion on IT hardware, software and services. (That includes SAAS like Salesforce and Office365 and managed services like RMM).
Amazon announced that they are getting in the Virtual Server space at $5 per month. They are starting selling cable-voice bundles for Comcast and Frontier. There is a heavy rumor that Amazon will be offering Hosted VoIP soon (possibly powered by BroadCloud).
You have to start thinking value-add, retention, customer satisfaction and upselling. I have been chanting outcomes and bundles for a long time. Going forward selling product just won’t work — they can buy that via a click on Amazon.
