Hi there, LisaH81.

I can share some information about how advertisements work in QuickBooks Online (QBO).

Currently, we're unable to turn off the ads in the program. They are specifically designed to guide you in managing your company. Although, I definitely understand how inconvenient it can be when an advertisement suddenly pops up upon working in the program.

Please know that we implement updates based on our customer's requests. Rest assured, we're taking note of your ideas and suggestions to improve and optimize your QuickBooks experience.

For now, you can click the X icon to close the advertisements so they won't affect your navigation experience. As we assess this opportunity, I recommend visiting our blog from time to time to stay current with our product updates and enhancements.

Also, you can check some of our helpful articles here if you need a reference in completing your tasks.

If you have any other questions, just let me know and I’ll make sure to answer them. Thanks for checking out QuickBooks Community and have a great rest of the day.
