# Kustom B2B (Billie)

This article explains how to activate Kustom B2B (Billie) in your online store. The solution allows business customers to pay by invoice and credit through Billie in Kustom Checkout.

## What Is Kustom B2B (Billie)?

Kustom offers a B2B payment solution through **Billie**, enabling business customers to purchase on credit in your online store.

When the solution is activated:

-   Customers can choose **Private individual** or **Company/Business** in checkout
-   Business customers can pay by **invoice through Billie**
-   Kustom handles the credit check and payment follow-up

> Already B2B activated?
> 
> If you already have Kustom B2B activated, you don't need to do anything since Billie was automatically activated on August 7.  
>   
> **Nb!** If you only sell B2B, you will not be able to use Billie. Billie is an alternative payment solution for B2B customers when you also sell B2C.

## How to Activate Kustom B2B (Billie)

### Step 1: Contact Kustom

-   Contact **Kustom support** and request activation of **B2B (Billie)** on your account.
-   You will need to provide your **Kustom ID**.

You can find it here:  
**Control Panel → Extensions → Your extensions → Klarna Checkout V3 → Credentials**

### Step 2: Contact Mystore Support

Once Kustom confirms that B2B has been activated:

-   Contact **Mystore support** so we can enable B2B in your checkout.

You can do this via:

-   Chat in the control panel
-   A support request

## Result After Activation

Once the solution is activated, checkout will display a new option:

If the customer selects **Company/Business**, they can pay by invoice through Billie.

## Important to Know

-   Credit checks are handled by **Kustom/Billie**
-   The payment option is only displayed for business customers

Please include:
