Hi robert-go4-d-com,
It's great to see that you're making use of QuickBooks Online's Products and Services section to manage inventory for your books. This easy-to-use feature provides the basics of inventory management, and I like your attention to detail with how making a product inactive has impacted your prior invoices. I can explain what's going on.
When you make an inventory item inactive in QuickBooks Online, it'll show the (deleted) status next to the item on the forms where you used it. This is to show you that the item is no longer an active part of your inventory. Don't worry, the (deleted) tag won't impact your transaction calculations and you can still receive payments against the invoice if it's still open. You can also go back and reactivate the item in your Products and Services section if you ever need it again. This article has the steps to reactivate if you'd like to do that: Add product and service items to QuickBooks Online
Feel free to share some feedback with our product development team about the term used and the way it displays when you make an inventory item inactive. Your comments help the team know what steps to consider to grow QuickBooks Online and have it continue to respond to the needs of business owners and bookkeepers. This article explains how to leave feedback: How do I submit feedback?
