Thank you for joining our Community, e-salon. I'm here to ensure you have all the information you need to effectively address your questions regarding correcting product and service item types in QuickBooks Online.
To make sure we give you the most accurate information, could you please confirm if you migrated from QuickBooks Desktop or another software? When migrating from QuickBooks Desktop, service items should transfer over as service items, not as inventory.
If you're seeing discrepancies, one option might be to run the migration process again on QuickBooks Desktop to overwrite the existing files and correct any issues from the initial migration. This could help resolve the unexpected behaviors you've encountered.
If you migrated from a different software or prefer not to undergo another migration, you can deactivate the inventory items and then recreate them as service items.
Additionally, here is the article you can check and get helpful insights on the things you buy and sell, and the status of your inventory: Use reports to see your sales and inventory status in QuickBooks Online.
