# Custom fields

> Add your own fields to customers and suppliers, such as a delivery area or a tax number.

*Section: Team and settings · Updated: 2026-10-19*

By the end you will have added a field of your own to your customers, such as the area you deliver to, and filled it in on a customer.

Custom fields add your own questions to the customer and supplier forms. They show on the customer's and the supplier's details, and in the POS's quick-add form. They don't print on receipts or invoices.

## Add a field

1. **Open [Settings › System Settings](/app/settings/System_settings) and the Custom Fields tab**, or go straight to [Custom Fields](/app/settings/custom_fields).
2. **Choose Customers or Suppliers.**
3. **Click Create.**
4. **Type the Field Name.** It is required, and it is the label people will see, such as **Delivery area**.
5. **Pick the Field Type.** **Text**, **Number**, **Textarea** (several lines), **Date**, **Select** (a list to choose from) or **Checkbox**.
6. **For a Select, write the Select Options**, one per line. For the other types, **Default Value** fills the field in advance.
7. **Switch on Required** if every customer must have it. Leave it on **Optional** otherwise.
8. **Click Submit.**

*A Select field: each line of Select Options becomes one choice.*

*The list reads from right to left: the field's name is on the right, its buttons on the left.*

**Sort Order** is saved but doesn't change the order yet: fields show in the order you made them.

## Fill it in on a customer

The new field appears under **Custom Fields** at the bottom of the customer form, when you create or edit a customer, and in the POS's **Quick Add Customer**.

*Pick the customer's area from the list.*

> **Warning:** A **Select** field starts filled with its whole list, written as one line in brackets. Pick the right choice for each customer, or clear it with the cross: saved as it is, that line becomes the customer's answer.

The answers show on the customer's details, under **Custom Fields**.

## Change or delete a field

- The pencil changes a field's name, type, options or **Required**.
- Deleting a field hides it and its answers from every form and details page. Make sure you no longer need them.
