Custom Functions in Zoho CRM allow you to extend the functionality of the CRM by adding your own custom code. This can include things like custom calculations, validations, or automation workflows. Custom functions are written in Deluge, an easy-to-use programming language specific to Zoho, and can be triggered by events like record creation or update.
When you create a new Custom Function, you will need to provide a name for the function and then enter the Deluge code that you want to use. Here is an example of a Custom Function you may find useful, as it rolls up the total revenue from all Potentials (Deals) to the associated Account, whenever a Deal is closed successfully.
