Custom fields in Zoho CRM let you extend the default data model of any module to capture the exact information your business needs — no two sales processes are identical, and custom fields ensure your CRM reflects yours.
What is it
Custom fields in Zoho CRM are user-defined data inputs you can add to standard or custom modules — such as Leads, Contacts, Deals, or Accounts — beyond the fields Zoho provides out of the box. Using a drag-and-drop interface in the Layout Editor, administrators can create fields of various types (text, number, date, picklist, lookup, address, and more) and arrange them within record layouts. These fields store business-specific data, feed into automation rules, appear in reports, and can be made mandatory, read-only, or conditionally visible depending on your workflow requirements. [2]
When to use it
- Capturing industry-specific data — A logistics company might add a "Shipment Type" picklist to the Deals module to track freight categories that no standard field covers. [1]
- Linking records across modules — Use a lookup-type custom field to associate a Deal with a custom "Projects" module, giving sales reps instant visibility into delivery status from within a contact record. [1]
- Enforcing structured address input — Add a dedicated Address field to ensure reps enter city, state, and postal code in separate, validated sub-fields rather than a free-text block, reducing data quality issues. [3]
- Driving automation and field updates — Custom fields act as triggers or targets in workflow rules; for example, automatically updating a "Contract Tier" custom field when a deal value crosses a threshold. [2]
- Controlling what appears on mobile — Define which custom fields surface on the Zoho CRM mobile app's record view so field reps see only the data relevant to their on-the-go tasks. [5]
- Powering client scripts and custom buttons — Custom fields can have their visibility, mandatory status, and read-only state toggled dynamically at runtime using Client Script, enabling guided data-entry flows without page reloads. [6]
How to access it
In Zoho CRM, navigate to Setup → Customization → Modules and Fields, select the module you want to modify, then open the Fields tab or click Edit Layout to enter the drag-and-drop Layout Editor. From the field palette on the left, drag the desired field type onto the layout canvas, configure its properties (label, data type, mandatory flag, default value, and permissions), and click Save. Custom fields can also be created and updated programmatically via the Zoho CRM REST API using the Fields metadata endpoint, which is useful when deploying field configurations across multiple CRM accounts at scale.
