Module Customization

Modules in Zoho CRM

Modules in Zoho CRM let you categorize and keep track of various aspects of your business such as Sales, Marketing, Customers, Products, Events and the like. Modules in Zoho CRM are represented in the form of tabs such as Leads, Contacts, Potentials, Activities etc. They are of two kinds.

    • Standard Modules
    • Custom Modules or User-Generated Modules

Standard Modules

Zoho CRM lets you work with more than 10 standard modules for Sales, Marketing, Customer Support and Inventory management. These predefined modules come with a set of default fields and layout. You can edit most aspects of a standard module to suit your requirements. For example, if there is a field called Twitter in the Leads module and you think none of your leads use Twitter, you can remove this field from the Leads layout. Similarly there are many other customization options provided to Standard modules. The customization options and their exceptions vary depending on the module you wish to modify.

Standard, predefined modules are available to all Zoho CRM users, regardless of the Edition they have subscribed to.

Custom Modules or User-Generated Modules

Sometimes, the standard, predefined modules present in Zoho CRM do not always meet all your requirements. In such a case, Zoho CRM lets you create a new module depending on your business needs. For instance, Leads, Contacts and Potentials will not be ideal for an educational institution. Students, Teachers and Parents would be more appropriate modules for them and they can create these modules. A hospital can create new modules called Doctors, Patients, and Nurses.

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's 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 "Customize Zoho CRM" permission can create/customize modules. Administrator profile users will have this permission by default.

With Zoho CRM's simple WYSIWYG Module Editor (What-You-See-Is-What-You-Get Editor), you can create new modules as well as edit existing modules easily.

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.

Module Customization - In a Nutshell

Using the What-You-See-Is-What-You-Get (WYSIWYG) Module Editor you can easily create/edit modules in Zoho CRM. Take a quick glance at how to use this editor to customize your module.

  1. Name/Rename the module.
  2. Drag and drop one or more fields to the layout from the New Fields tray and click Save Layout.
  3. Edit the Field Properties and Set Permissions for the fields from the Settings icon. Remove fields from the Layout using the Trash icon.
  4. Drag and drop new sections to the layout from the New Fields tray.
  5. Switch between single-column layout and two-column layout for a section. Move the sections around to rearrange them. Use the Delete icon to delete a section.
  6. View the removed fields in the Unused Fields section.
  7. Set Module permission for different user profiles.
  8. Preview the module layout as a particular profile. This is useful if you have given different Field Permissions for different user profiles.
  9. Save the Layout, once you are satisfied with it.

As you add new fields and remove existing fields, Custom Fields Left automatically tells you how many more fields you are allowed to create based on the field limits applicable for your Edition.
