Hi, @Rozmore13.
While I can't suggest applications to integrate, you'll want to discover them from the Apps menu. Doing this can help you check for third-party applications to manage rentals history and maintenance work order systems that can be used in conjunction with the mobile app.
Here's how:
- Login to QuickBooks Online.
- Go to Apps and then select Find apps.
- Click the application to check their key benefits.
- If it suits your needs, hit Get app now or contact their support for more details.
- Follow the on-screen instruction to integrate the app.
You can also visit our supported apps website: Apps help QuickBooks run better.
For more details about adding and managing apps, see this article: Install and use apps in QuickBooks Online Accountant.
Please don't hesitate to comment if you have other QuickBooks Online concerns.
