I appreciate you reporting this issue to us, @Eat-Flare.
To assist you better, could you inform me if you encountered an error message while adding an inventory item? Any additional details would help us explore potential solutions for you.
Also, please verify your access to the QuickBooks account. You may have limited permissions, which could prevent you from managing the Products & services.
If you have confirmed your access but still cannot add inventory items, we can perform basic troubleshooting steps to determine if the issue relates to your browser or the QuickBooks system.
Let's start by clearing your browser's cache. This will refresh your system and remove any outdated files that may be causing issues. Doing this can also free up space and improve your device's performance, as many common problems are often related to browser settings or the cache itself.
If the problem persists, consider switching to a different supported browser to ensure the best experience with QuickBooks.
If you have any follow-up questions or concerns, please don’t hesitate to reach out for additional guidance.
