# How to add custom fields to my contacts? (Expected delivery date, etc.)

If you wish to add additional fields to your contact forms, you need to use [the custom fields](https://www.fotostudio.io/app/custom_fields).

Once created, you will be able to fill in this custom field when you create or edit a contact. These custom fields will also be displayed in the contact's file.

||| To learn more about custom fields, see the category [Custom Fields](https://help.fotostudio.io/en/category/custom-fields-127di48/).

||| It is possible to create a variable for each custom field, which allows you to insert it into your emails and contracts. See the article [How to create my own variables?](/en/article/zkbisk//).
