My quotes do not save. Lost a full days work. Extremely frustrating. Any help?

Welcome to the Community, @dirk-pivotprosa-.

Let's perform some browser troubleshooting steps to isolate the issue. To start, access your QuickBooks Online (QBO) account using an incognito mode. A private browser prevents storing cache and web history to avoid issues when running frequently visited websites. Below are the shortcut keys you can use: 

• Google Chrome: press Ctrl + Shift + N 
• Mozilla Firefox: press Ctrl + Shift + P
• Microsoft Edge: press Ctrl + Shift + P
• Safari: press Command + Shift + N

Once signed in, create quotes again and save. If this works, you have to clear your browser's cache to have a clean slate. If the same result, use another supported browser.

Also, feel free to reach out to our Customer Care team to guide you through doing any of your QuickBooks tasks. Live support operating hours are from Monday through Friday 8 AM to 6 PM South African Standard Time.

Keep me posted if you have further concerns about saving your quotes. I'll be on the lookout for your response. Take care always.
