Building Custom Modules

Zoho CRM offers more than 10 standard modules for Sales, Marketing, Customer Support and Inventory management. These modules have predefined business logic, including page layout, reports, and workflow automation, which cannot be completely modified to accommodate your other business processes. Every business has a set of requirements that may not fit into these standard modules. You may require modules that are unique to your organization; that would cater to the needs of your organization, store data that is relevant to your business process and most importantly, be linked with the other standard modules in your account.

For example, a real-estate company using Zoho CRM would like to track not only leads, contacts and prospects but would also want to tightly link with properties, buildings, etc. Without these modules, customer life-cycle management is incomplete.

To address these unique business requirements, you can create your own modules. With the Custom Modules functionality in Zoho CRM, you can develop new modules using built-in tools that need no programming skills. These custom modules can seamlessly integrate with core CRM modules and need not be stand-alone modules. What more, you can:

  • Add fields and modify the page layout as per your needs.
  • Use roles and profiles to define access controls for the custom modules and its fields.
  • Import data to the custom modules with ease.
  • Take a backup of your data, anytime.
  • Send mass emails to the records in the custom module.
  • Create mass email schedulers.
  • Use macros to execute a set of actions.
  • Create workflow rules to automate your business process.
  • Build module relationship by linking custom module records with standard module records.
  • Use autoresponders to send automated replies and follow-up emails.


Permission Required: Users with Administrator profile can create custom modules.

Difference Between Custom Modules and Custom Apps Features

Both Custom Modules and Custom Apps are two different functionalities in Zoho CRM that helps you extend your CRM to suit the requirements that are unique to your business.

  • Custom Modules - Create custom tabs, just like other standard modules, and build module relationship by linking custom module records with standard module records. Like other standard modules, you can customize, import and export data, configure workflow rules and generate reports for the custom module.
  • Custom Apps - Create custom applications, forms and views (powered by Zoho Creator) and use them to build custom tabs inside Zoho CRM.
