How do I make my final inventory item inactive? error stating: This product or service can't be made inactive because it is the default product or service for sales.

Hi @mtr.castle,

Let me walk you through on how you can successfully downgrade your QuickBooks Online (QBO) subscription.

What you're trying to make inactive is the Sales service, which isn't an inventory type. What you need to do at this point is to turn off the inventory feature instead. 

I'll show you how:

1. Go to the Gear icon.
2. Select Account and Settings.
3. Click the Billing & Subscription tab.
4. Tap the Choose Plan link.
5. Hit Continue.
6. When finished, press Change plan, then Done.

In case you need to disable other features to proceed with the downgrade, see this article: Downgrade your QuickBooks Online plan. You'll find the steps on how you can disable features such as recurring transactions.

In the future, should you wish to go back to your original QBO subscription, refer to this article: Upgrade your QuickBooks Online subscription. 

Place a comment below if you have other questions. I'll get back to you as soon as I can.
