Thank you for reaching out to the QuickBooks Community, simon33. Improving the product search functionality in the QuickBooks mobile app can certainly enhance your invoicing process, and we’re here to help.
Currently, the QuickBooks Online mobile app is designed to search for products and services by name only, not by description. At this time, there isn’t a setting available to change the search functionality to include descriptions.
As an alternative, you can use QuickBooks Online through your mobile browser. The browser version offers a more comprehensive search feature, allowing you to locate items by description.
If you have any further questions or need additional assistance, please don’t hesitate to reach out. We're always here to help.
