I'm here to provide a helpful overview of how the online software works about saving invoices, Lem3. Let me share some key details to clarify the process for you.
In QuickBooks Online, the option to automatically save invoices while you work on them is currently unavailable. Therefore, it's essential to manually save each transaction once finished to prevent losing your progress. With this, you can choose Save, Save and Close, Save and Share Link, Save and Send, or Save and Share.
