Changing service items to inventory - how will effect past invoices.

Hello there, @mphillips4.

You have the option to convert a service item into inventory, but please note that this action will not change the three line items into a single line item.

You can follow the steps below:

1. In the upper right corner of your screen, hit the Gear icon.
2. Under the Lists column, choose Products and Services.
3. Find the service item you want to change.
4. Click Edit in the Action column.
5. Select Change Type.
6. Choose Inventory.
7. Follow these steps to set this item up as an inventory item.
8. When you're done, select Save and Close.

Moreover, I recommend consulting with your accountant before doing so to make sure the changes are appropriate according to your business needs and accounting standards.

On the other hand, you can also merge all service items into one. Refer to this article: Remove a product and service in QuickBooks Online, scroll down a bit, and find: merge a non-inventory item and service. However, this will affect your historical transactions and financial reports.

To make sure your past transactions are safe, I highly recommend you start tracking upcoming transactions with new inventory items instead.

Please don't hesitate to inform me if you still need assistance in changing your service items into inventory. I'd be more than happy to help you. Stay safe.

If changing the type to inventory doesn't post the cogs and adjust inventory - then what is the point of having inventory.
