Hi unlimitedservers,
Users added in QuickBooks Online (QBO) will be able to use the mileage app since QBO is a cloud-based program that can be accessed anytime and anywhere. You'll want to add the user to QBO.
Here's how:
- Click the Gear icon.
- Select Manage Users.
- Click Add user.
- Select the user type you want to create. More options will appear on the screen depending on the user type you select.
- Enter your new user’s name and email address, then click Save.
To track mileage, you'll have to turn it on. Please see this article for more information: Track Mileage in QuickBooks Online.
Feel free to let me know if you need anything else. I'll make sure to help.
