That depends on the amount, complexity and quality of your data. Some migrations take a couple of weeks; others have taken more than a couple of months. Before we start work you will receive a clear estimate of the cost and time involved in your implementation. Of course, agencies with very straightforward migration needs import their data themselves using the tools that come with NextAgency.
Please keep in mind, during the NextConcierge process you are responsible for gathering and sharing your data. You also need to sign-off on the finished work. How long the entire process takes, consequently, depends on how fast your agency accomplishes this.
