I am not able to find the “Assign User” option? What should I do?

You might have not found that option because you might have customers that have the Type set to Both. This option is not available in Zoho Books anymore.

To have this option enabled for your organization, please follow the instructions given below:

• Clone the contact with the Type as Both.
• Save it as Vendor and move all the purchase related transactions from the both to the vendor.
• After moving all the transactions, change the existing Both contact type to Customer.

Once you complete these steps, please send us a feedback. We will make the necessary changes from our end for you to view the option for the custom role.
