On Friday I was able to categorize banking transaction using products and services and by Saturday the drop down for products and service was no longer available.

Hi there, Craig.

Thank you for reaching out to the QuickBooks Community about the sudden disappearance of the dropdown for Products and Services in your banking transactions. This issue can be very challenging, especially when you need to categorize transactions quickly and accurately. Let’s work together to troubleshoot and resolve this.

Sometimes, changes in the user interface can be due to browser cache issues. As of now, I can guide you on troubleshooting your browser to ensure it runs with QuickBooks efficiently. Let's start with accessing QuickBooks Online using incognito mode or a private window. Here are the shortcut keys to go private mode in a browser:

For Google Chrome / Microsoft Edge / Opera:
 

• Windows: Ctrl + Shift + N
• Mac: Command ⌘ + Shift + N

For Firefox:
 

• Windows: Ctrl + Shift + P
• Mac: Command ⌘ + Shift + P

For Safari:
 

• Shift + Command ⌘ + N

If this works, you can proceed to clear your browser's cache and cookies. Otherwise, you can also use other supported browsers to ensure it runs QBO efficiently.

After categorizing your bank transactions, you can consider reconciling them to match accurately with your bank statement.

If you have any further questions or need additional assistance, please don’t hesitate to reach out again. We're here to ensure you categorize your bank transactions efficiently.
