Is there a way to store an employees phone number in payroll UK?

Good day, @Ewano.

The option to enter your employees' phone numbers is currently unavailable. That would be a great addition to the current features that we have, so I’ll take note of it. I also encourage you to leave feedback from within the product. 

Here are the steps:

1. Go to the Gear icon and select Feedback.
2. Provide your product suggestion. 
3. Click on Next to submit feedback.

You can check out this article for more information about providing feedback to make the program better: How do I submit feedback?.

Here's more information on how to add your employees to payroll and make any changes after adding them:

• Add employees in QuickBooks Online Standard Payroll
• Edit employees in QuickBooks Online Standard Payroll

I'm always here if you need more help in managing your employee's profile. Let me know by leaving a reply below. Have a great rest of the day!
