Can save any invoice

Hello 2557893albertalt,

Welcome to Community!  It's essential that you're able to save your work in QuickBooks Online.  I would be happy to provide some insight here!

In this situation, I suggest clearing the cache on your browser, if you haven't done so already. An excessive amount of frequently accessed page resources, can cause unusual behavior. In addition, I recommend trying another browser such as Google Chrome, Safari, Edge, Firefox, or a private browser. 

It's also important to ensure your account is active.  Here's how;

1. Sign in to your QuickBooks Online company as the Primary Admin

2. Go to Settings ⚙ and select Subscriptions and billing

3. Select Resubscribe, then enter the updated billing information

4. Hit Resubscribe.

If the issue persists, please don't hesitate to contact our Customer Care team at 1-855-253-1536 from Monday to Friday between the hours of 9 AM and 8 PM EST. They'll be able to review the issue in more depth, and escalate it for further investigation with our Development team.

If you have any other questions, feel free to reach back out.  We would be happy to help!
