Our customers try to install our product but can't get it working
It's surprising how often we hear this. Customers assume the solution will be plug-n-play but when it comes time to make it work, they end up overwhelmed and frustrated. Then come the calls to your support desk or the sales person. Many sales cycles are used up trying to help customers get their solution working.
Voodoo Wireless addresses this through implementation consulting. The client would call your support centre complaining about the product and your support centre would offer implementation services (which are white labeled to your company). In most cases, customers are more than happy to pay the additional consulting fees just to get it working and get rid of the frustration.
