Hello there, @Taramare.
Let me help provide some insights about searching for customers by using phone number in QuickBooks Online (QBO) mobile app.
The QBO mobile app is a simplified version of the program. Currently, there isn't an option to look up a customer by their phone number using QBO app. However, you can do this by accessing your company via a supported browser.
You can use the Magnifying glass icon to search a customer by phone number.
You can also pull up the Customer Contact List Report to show your customer's information including the phone number. Here's how:
- Go to Reports in the left navigation bar.
- Type in Customer Contact List in the search box.
For additional reference, you can check this article to learn more on what features are supported on mobile devices: Compare mobile app features.
Please know that you're always welcome to post if you have any other concerns. I'll be around to help you out. Have a good one.
