Start with finding a good system to track your customer feedback info. Without a system in place to collect and organize customer feedback, it will fall through the cracks. Use a tool such as Trello to keep customer feedback in a single place that all of your employees can access and contribute to.

You should also use a survey tool, like Fieldboom, that makes the process quick and easy to reach your customers best (and fast). It quickly brands your survey and configures all of your questions.
