I appreciate your efforts and time following the suggested resolutions, 22222. I'll chime into this conversation and offer my expertise so you can customize your sales forms according to your preferred content and appearance.  

The Bundle feature is only available in the QuickBooks Online (QBO) Plus subscription. Since you've already created a Bundle Feature, but the option to create it has suddenly been missing, it could be a browser-related issue.

We can open your account using an incognito or private window. Unexpected issues in QuickBooks Online (QBO) may arise due to problems with the web browser, such as a full cache or outdated internet files. A private or incognito window does not retain internet data like cookies, history, or cached files from previous browsing sessions, creating a fresh browsing environment.

Please refer to the following keyboard shortcuts based on your browser type: 

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

If the private browsing session works, clear the browser's cache to allow the system to restart. Clearing the cache refreshes the system, enabling you to begin with a clean slate. This process can also be carried out on supported and up-to-date web browsers recommended for optimal QuickBooks performance.

Additionally, we can use the Custom Form Style functionality to hide the Rates and QTY in your Invoices and estimates when you email these transactions to your customer. I'll show you how:

1. Go to the Gear icon and choose Custom form styles.
   
2. Select the New style dropdown menu and hit Invoice.
   
3. Enter a name for easier classification.
   
4. On the Content tab, choose the center section.
5. Uncheck the Quantity and Rate boxes.
6. Once done, click Done.
   
7. Follow the same process with your estimates.

Afterward, you can apply it to your sales transactions by selecting the custom template. You'll need to select the Payor view tab and click the Design tab, then choose the created template.  

I'll attach an image showing the comparison of applying the custom form template.  

Every business has unique needs and preferences when it comes to processing sales activities, 22222. Please feel free to ask any specific questions, and I'll do my best to provide clear insights and information to help you optimize the customization capabilities of the sales form within the system. Wishing you all the best for the remainder of the week! Stay safe and healthy.
