    • Why do I need a CRM custom development?

      read more
      Basically, the introduction of a CRM system does not necessarily require custom development. Most of the time, the need for this is due to the requirements of the business. Common topics that require custom development are for example: interface programming, UI/UX improvements, portal offers with end customer contact or complex business logics.
    • Are custom-developed CRM solutions future-proof?

      read more

      Our experts always design your solutions with an eye to the future and ensure that future upgrades to the system have no impact on the custom developed application, if possible.

    • How expensive is custom CRM development?

      read more

      There is no blanket answer to this: this depends heavily on the requirements and the degree of complexity. Basically, we prefer an agile process model in which you can view interim results at short intervals, so that target adjustments can be made early on if necessary.
