Error in adding products?

The error you got when adding products in QuickBooks Online (QBO) is likely caused by a browser-related issue. Let's work together to troubleshoot and fix this, info.

Your browser saves files to load websites faster on your next visit. But over time, it'll get outdated, which can cause errors and performance issues using QBO.

To fix this, you can perform some troubleshooting steps. Start by pulling up your QuickBooks Online (QBO) account using a private browser (incognito). Here's how:

• Press Ctrl + Shift + N (Google Chrome)
• Ctrl + Shift + P (Firefox)
• Control + Option + P (Safari)

Once signed in, go to the Products and Services page to add your new products. 

If you're able to do so, return to your default browser and clear its cache. After that, log out and then log back into your account. This will refresh the system and remove older data that causes viewing and performance issues. 

However, if this matter continues, I'd recommend using other supported browsers.

Additionally, when you add products and services as items in QuickBooks, you give them a type to help you with your categorisation for better tracking. If you pick the incorrect one, you can change it later on. To do this, you may want to check out this article: Change product and service item types in QuickBooks Online.
