Trying to save an invoice in qb online but getting application error. logged out, logged back in.. then restarted computer to clear data/cache..

Thanks for getting in touch with the Community, geri all star. I appreciate your detailed information.

Since you're encountering an application error when trying to save invoices, I'd recommend checking the browser you're using. It's possible you may be using an unsupported web browsing application. QuickBooks supports the current and two previous versions of browsers. If you find you're using an unsupported version, be sure to update it to its latest release. Steps for doing so can be found on the particular company's website.

Here's a list of supported browsers
 

• Google Chrome - version 78 or newer
• Mozilla Firefox - version 76 or newer
• Microsoft Edge - version 79 or newer
• Opera - version 68 or newer
• Samsung - version 10 or newer
• Safari - version 12 or newer

In the event you've found no problems that could be causing this with your browser, you'll want to check the operating system and internet speed you're working with.

Here's our recommended operating systems and internet speeds:

• Windows PC - Windows 10, Intel Core i3 or a comparable processor (2013 or newer) with at least 2 GB of RAM, or Windows 10, Intel Core i5 or comparable processor with at least 4 GB of RAM.
• Mac - OS X El Capitan 10.11, OS X High Sierra 10.13, or newer.
• Linux - QuickBooks works with Linux, but you'll want to make sure you're using a supported browser and our recommended internet speeds.
• Internet connection - 1.5 Mbps to 3 Mbps or higher.

If you meet our system requirements, but are still encountering an application error while saving invoices, I'd recommend using a different device and/or internet connection. If it continues happening on other devices and internet connections, you'll want to get in touch with our Customer Care team. They'll be able to pull your account in a secure environment, conduct further research with you, and create an investigation ticket if necessary.

They can be reached while you're signed in.
