Is there is no automatic saving while preparing an invoice?

Nice to see you in the Community, enilag2016-gmail.

At this time, the option to auto save an invoice is unavailable. If you're logged out from your account in the middle of creating an invoice, you'll want to adjust the sign out time frame.

Here are steps:

1. Go to the Gear icon > Accounts and Settings.
2. On the left panel, click Advanced.
3. Select the Other preferences section, and choose your preferred time from the Sign me out if inactive for drop-down menu.
4. Hit Save then Done.

I'm adding this article for reference: Change the timeout duration in QuickBooks Online. You can also utilize the QuickBooks Online Desktop App, which allows you to stay logged on. To download the app, click on this link: Get the QuickBooks Mac & Windows Apps, Powered by QuickBooks Online.

I'll be right here to answer any follow-up questions you have or help you with other QuickBooks concerns. Take care and stay safe.
