Before you finalize the SaaS product launch, make sure that the launch is scheduled around a specific date like a customer event, an anniversary etc but do not develop it in vacuum, discuss it with product, marketing, sales, customer service, and executive teams. Your customer must be forefront of your mind because he will give you feedbacks to innovate yourself if the product is not functional. Therefore, it is incredibly important to beta test with current clients.
