# How do I configure shop settings?

This article covers two common shop settings: adding your GST Registration Number to order receipts, and linking your shop to your Facebook page.

***

## Add your GST Registration Number

If your restaurant is GST-registered, you can display your GST Registration Number on customer order receipts.

1. In Merchant Admin, go to **Stores** and select your store.
2. Open **Store Information**.
3. Add your GST Registration Number to the store name field — for example: `ION (GST Reg No: 123456789A)`.
4. Click **Save**.

Your GST Registration Number will then appear on all order receipts for that store.

## Add a Shop Now button to Facebook

Linking your Oddle Shop to your Facebook Business Page makes it easy for followers to go straight to your ordering page.

1. On your Facebook Business Page, go to your cover photo and click **Add a Button**.

{% hint style="info" %}
Facebook only allows one button per page. If you already have a button, hover over it and click **Edit Button** to update it.
{% endhint %}

Once set up, consider pinning a post about your online ordering to the top of your page so it's the first thing visitors see.
