It's nice to have you here in the Community, GBE.

Let me share with you some information about Sales Rep in QuickBooks Online (QBO).

At this time, the Sales Rep feature is unavailable in QBO and there isn't a way to batch update the Sales Rep. However, you can use the use the Location/Class Tracking feature. To turn on this feature,you can go to the Company Settings.

Here's how:

1. Go to the Gear icon.
2. Select Account and Settings.
3. Click Advanced.
4. Click Categories.
5. Put a check mark in the box labelled Track locations.
6. Click Save.
7. Click Done.

If you wish to have this feature available on our future updates, I encourage you to send this suggestion to our product developers through feedback. I'll be sure to do the same on my end.

Here's how:

1. Click the Gear icon.
2. Choose Feedback.
3. Enter your request/product suggestion, then click Next.
4. Select Feedback as the Category.
5. Click Send message.
