Settings & Custom Fields

The Settings page under Contacts is where you configure custom fields for Contact, Company, and Calendar records, and review the built-in system fields.


Accessing Settings

Click Settings in the left sidebar under Contacts.

The page has three tabs — Contact Custom Fields, Company Custom Fields, Calendar Custom Fields — and within each, a toggle between Custom Fields and System Fields.

System Fields is read-only: you can search it, but there's no add/edit/delete/import here. See System Fields & Custom Fields for the full list.


What Are Custom Fields?

Custom Fields let you add extra data fields to Contacts, Companies, or Calendar records beyond the built-in fields — for example, a Lead Score, Preferred Language, or Subscription Plan field specific to your business.

Once created, a custom field can appear:

  • As a column in the Contacts/Companies list (toggle via Manage Fields)
  • As an input on the Contact/Company create-edit form (if you enable Show in ... Form)
  • In the hover preview under "More Information"
  • As a filterable field in the filter builder and the CSV import mapper

Creating a Custom Field

On the Custom Fields tab, click Add New.

Custom Fields tab in Settings with the New Field button The Custom Fields tab shows all existing custom fields. Click Add New to add one.

The creation form is a three-pane layout: pick a field type on the left, configure it in the middle, and see a Live Preview with a Field Summary on the right.

Common Settings (every field type)

  • Field Name — required, 3–50 characters, letters/numbers/spaces only. As you type, QuantixOne checks name availability and warns you if it conflicts with a system field name or an existing custom field.
  • Placeholder — optional hint text shown in the empty field.
  • Model — Contact, Company, or Calendar. This is locked once you're editing an existing field.
  • Description — optional helper text shown under the field.
  • Required Field — toggle to make the field mandatory before saving a record.
  • Show in [Model] Create/Modify Form — toggle to control whether the field appears on the create/edit form, as opposed to only in list and detail views.

Click Create Field to save (or Save Changes when editing).

Managing Existing Custom Fields

To edit a custom field, click the Edit (pencil) icon next to it in the list. To delete one, select it and use Delete — this works on a single field or in bulk.

Note: Deleting a custom field permanently removes the field definition, all stored values across every record, and any references to it in filters, views, or reports. This action cannot be undone.


Bulk-Importing Custom Fields

Click Import on the Custom Fields tab to open the field import wizard (Contacts > Settings > Import):

  1. Upload File — CSV, drag-drop or Upload File, 5 MB limit. Click Download Sample for a template. Required columns: Field Name, Module, Type. Optional: Display On, Description, Placeholder, Required, Options, Show In Forms.
  2. Preview Fields — review the parsed rows, then click Confirm & Import.
