# Design a Custom Teams App for Your Customers
> Use the Thread Admin Panel Teams App Builder to design and deploy white-labeled, branded Microsoft Teams support apps for each of your MSP customers.
## Overview
### Create a white-labeled Teams app for your customers
From the Admin Panel, you have the ability to create a branded Teams experience that you can deploy to your customers. Best of all, you can create multiple different apps with different brandings, if you have customers that prefer their own branding in their Teams app.
## Access the Teams App Builder
To access the Teams App Builder:
Navigate to your Thread Admin Panel
Click on **Messenger** in the left navigation bar
Navigate to the **Teams Apps** tab at the top-center of your browser window
Click **Create New** if you wish to create a new custom Teams App, or **Edit** or **Duplicate** an existing app
If you clicked **Create New** on the previous screen, you will be brought to the Teams App Builder.
1. Please follow these guidelines for the App icons [here](https://learn.microsoft.com/en-us/microsoftteams/platform/concepts/design/design-teams-app-icon-store-appbar)
Now you can customize your app, the entire experience is brandable and customizable. *When naming your App, we recommend a name that can be recognized by your customers' users for the type of service you provide, e.g IT Support.*
Here you can edit the support pages displayed on your app, and also preview your app design. To change the color of these support buttons:You can go to the design page of the messenger settings and change the primary color. Then all you have to do is click "save" and then after a refresh of teams the color will change
The customizable Teams app embeds a version of Messenger on the right for your customers to open chats with your team. This inherits the Messenger branding settings you set at the parent level, or if you are overriding these settings at the customer level, it will inherit those settings for that Customer.
## Find your Thread App ID
Your **App ID** is the unique identifier used to deploy Messenger to customers. Find it in the
Admin Panel under **Messenger → Installation**, in the **APP ID** box.
Each client also has its own App ID. Deploy with a **client's** App ID when you've set
[client-level overrides](/messenger/configurations-in-messenger) you want that customer to get.
## Banner image specifications
The banner is the widest branded element in the app, so it's worth getting right:
| | |
| ---------------- | ------------------------------------------------------------ |
| **Minimum size** | 2744 × 478 px |
| **File size** | Keep under 1–2 MB for faster loading |
| **Safe area** | Put logos and text in the **middle** — the edges get cropped |
Use a high-resolution image. If you need stock imagery, free copyright-free sources such as
[Pexels](https://www.pexels.com/) work well.
## FAQ
Yes. The **Teams App Builder** is in the Admin Panel, and you can create **multiple** apps with different branding — useful when customers want their own look rather than yours.
Yes, but it isn't self-serve — Thread builds it for you. Email **[help@getthread.com](mailto:help@getthread.com)** to request a white-labeled Slack app, then [deploy it to a customer](/messenger/deploy-the-slack-service-app). Allow up to 5 business days.
