Think through all that entails! You really need to do your homework on this one. Yes, Zoho support and their thousands of help articles and community forums are available as a resource, but they cannot always provide the help with solution you need right away.
You really need to come up with a good plan so that every step of your implementation is clear and so you can be confident it’s doable.
Do you have time to build it yourself? Is there anything outside of your skill set that could cause problems?
