I've got your back,@stephen60.

I recognize the urgency of fixing this so you can continue managing your business. Let's get your sales transactions working again seamlessly.

You'll want to access your account through an incognito window to rule out the possibility of having a browser-related issue. It causes discrepancies that affect the view and performance of your QuickBooks, specifically with your invoices and quotes.

You can use these keyboard shortcut keys to open it in all supported browsers:

• Google Chrome: Ctrl + Shift + N
• Safari 11 or newer: ⌘ + Shift + N
• Mozilla Firefox: Shift + Ctrl + P
• Microsoft Edge: Ctrl + Shift + N

If it works, you can return to your original browser and clear its cache to start fresh. You can also use another supported, up-to-date browser.

Furthermore, this article can give you some handy details to personalise your transactions: Customise invoices, quotes, and sales receipts in QuickBooks Online.
