Invoice import (.csv) keeps getting unknown error message re: can't add items. Tried manually adding them exactly to match import data - also doesn't work. Please help?

Your efforts to resolve the issue with importing invoices to QuickBooks are appreciated, chair4. Here are some troubleshooting steps to help you successfully import your invoices.

There must be an overwhelming volume of browser data, which slows down the system's performance. To address this, let's open your account using a private browser to isolate the issue.

Please follow these keyboard shortcut keys to proceed:

• Safari: Command + Option + P
• Google Chrome and Microsoft Edge: CTRL + Shift + N
• Mozilla Firefox or Internet Explorer: Shift + CTRL + P

If you can successfully import your invoices while using private windows, this indicates there is an issue with your regular browser. To resolve this, let's start by clearing the cache and cookies of your browser.

However, if the problem continues, you can use a different supported browser to troubleshoot further.

If the issue persists even after performing some browser troubleshooting, we highly recommend contacting our Customer Care Team.

By doing so, they can access your account in a secure environment and conduct further investigation to determine the root cause of the problem. They'll then provide a resolution to help you import invoices to your company file.
