# Internal customer profile fields

> Keep customer preferences and information between visits.

Open **Settings → Customers → Custom fields**. Staff fill in these fields on the
**customer profile**: preferences, loyalty references or information useful at
reception. Customers cannot see or fill them in on the portal.

## Configure a field

1. Add a field with at least a French or English name.
2. Choose text, number, date, yes/no, single choice or multiple choice.
3. Configure choices and unique values, numeric limits or the maximum number of
   selections as appropriate.
4. Enter help text, an optional placeholder, and the **Active** and **Required**
   options.
5. Save and check the field in a customer profile.

The **type cannot be changed after creation**. If you need another type, create
a new field and arrange to transfer information with your team; existing values
are not automatically converted.

## What are the values used for?

A value stays available on subsequent visits by the same customer. It can also
help [filter or segment customers](/marketing/segments).

Example: “Seating preference” with Terrace / Indoors options. It informs staff;
it does not automatically reserve a room or table.

## Choose the right place

* Lasting internal information: this customer field.
* A question customers answer for a visit:
  [booking field](/portal/custom-fields).
* A question for an activity: [activity field](/activities/fields).

Managing these fields requires permission to update customers. If a field is
missing, check the location, activation and staff permissions.
