# SaaS App User Guide

> Learn how to purchase and use SaaS apps, including buying through the DingTalk App Marketplace or a proprietary channel QR Code, configuring options after becoming an App Admin, and quickly authorizing and enabling SaaS Cool Apps. This guide also outlines product boundaries for the SaaS app data module, integration & automation, and platform basics, and answers common questions such as whether upgrades and plan changes are supported after subscription.

## How to Purchase a SaaS App

Organization admins can purchase listed SaaS apps through a proprietary channel QR Code or from the DingTalk App Marketplace. The following example uses "proprietary channel promotion":

<Warning>
  ⚠️ Organization users cannot purchase apps directly. Contact your admin to purchase and enable the app. The admin must have the "App Center management: can enable and try apps and services in the App Center" permission.
</Warning>

> Special note: During the grayscale co-creation period, if a customer needs to place an order, contact the YiDA official team after the order is placed.

## How to Use the SaaS Main App

<Steps>
  <Step title="After the Organization successfully purchases the app, access it from the Workbench" />

  <Step title="The purchaser becomes the App Admin by default and can enter the app backend to configure business modules as needed" />
</Steps>

Some features support personalized configuration by the admin after the customer enables them. The logic follows "Trial Organization Management > Trial Main App Testing."

<Steps>
  <Step title="Under App Layer > Basic Settings, review the purchased product specifications and expiration date of the current app, and manage account authorization as needed" />

  <Step title="Expiration reminders are sent 30, 15, 7, 3, 2, and 1 day(s) before the SaaS app expires" />
</Steps>

## How to Use a SaaS Cool App

Once a SaaS app is successfully listed, open a Group Chat (such as an Internal Group), click "Cool App Marketplace" in the Chat Quick actions, locate the current SaaS app, and authorize it to enable directly.
