Good day, info1837.
I'll take that you want to change the license number on your QuickBooks Desktop for Mac.
Let me guide you with these steps:
- From the QuickBooks menu, select Manage My License.
- Select Deauthorize This Computer.
- Click Deauthorize and Quit.
From there, re-open QuickBooks and follow the registration process. It'll let you enter a different license.
On the other hand, QuickBooks Online doesn't have a license number. They have a Company ID. You can locate it on the Billing & Subscription page. Here's how:
- Click the Gear icon.
- Choose Account & Settings.
- Select Billing & Subscription on the left.
- Go to the Company ID section.
You can also manage your QuickBooks account on the CAMPs page: Change, manage, or update your Intuit account.
You can always get back to this thread whenever you have concerns with QuickBooks.
