Is there a limit on the number of tags you can create in qbo and can a single transaction have more than one tags??

I can share some information about how tags work, isofos.

Please know that there's no limit on the number of tags you can add or create in QuickBooks Online. You can also attach as many tags as you like to a transaction. However, you can only choose one tag per group. Here's how:

1. Click the + New button.
2. Choose a transaction.
3. Enter the necessary information.
4. From the Tags field, select the appropriate tag for each group.
5. When you're done, click Save and close.
