We take full responsibility for your customer portal, which means that we also create and take responsibility for the connection to your business system. So no, you don't have to create the connection to your business system.
When connecting to the business system, we contact the supplier of your business systems (or other business solution that you want to connect Bizzjoiner towards) to together determine the best method for setting up the connection.
If you have a more modern business solution, chances are that there are already good interfaces that we can connect with.
Can I connect Bizzjoiner to any business system?
What details are retrieved from the business system to the customer portal?
