Hi kchris10,

Welcome to Community!  It's important to keep your products and services up to date to save valuable time when creating forms.  QuickBooks Online provides the flexibility needed when items change.  I'd be happy to provide more information so you're on the right track with your work!

To locate changes that were made to the your inventory, you can go to Settings ⚙ > Audit log.  If you need to make changes to the COGS, you can edit the inventory items by following this helpful guide.  When editing the items you'll see the option to update price in recurring templates.  However, changing the price of an item won't affect existing transactions.  In addition, once you've reviewed the information in the audit log, you can make any necessary changes to user roles and access rights as you see necessary.

If you require additional assistance with this situation, please don't hesitate to contact us.  It would be our pleasure to work with you directly and ensure you're back to business as soon as possible.
