What determines how long it takes?
We can only give an honest timeline after the process review. These factors determine it:
The scope. How many areas go live at once, and how many users and sites are there?
Your availability. The timeline depends not only on our work, but also on the time your project lead and key users can free up.
Your data. Cleanly supplied data goes faster than data that first needs cleaning up.
Custom development and integrations. An existing integration is set up faster than a new one; custom work needs time to build and test.
Starting in phases. You can begin with one chain, for example from quote to invoice, and extend afterwards. That way you are working sooner with a first part.
