Welcome to the Community, @nbyron.
When we upgrade your QuickBooks Online (QBO) subscription from Plus to Advanced, it doesn't wipe out all your existing data. Instead, it'll add the features exclusive to the Advanced subscription.
Here's how to upgrade:
- Sign in to your QBO account as a primary or company admin.
- Go to the Gear icon and select Account and settings.
- Click the Billing and Subscription tab.
- Ensure your payment info is updated.
- In the QuickBooks Online section, click Upgrade your plan.
- Select Choose plan for the Advanced version.
- Follow the on-screen instructions to upgrade your plan.
If you wish to have a copy of your existing QBO company, it's only available in the Advanced version.
Moreover, please refer to this article if you need to update the card on file, change your subscription, or simply view your billing history in QBO: Manage billing, payment, and subscription info in QuickBooks Online.
Please don't hesitate to leave a response below if you have more concerns about upgrading your subscription. We'd be glad to assist you.
