If your login is associated with multiple PayHero accounts, you can switch or select which PayHero company you're logged into at any time.
From the Welcome Screen
When you login to PayHero you will be prompted to select which company you would like to login to.
This will only occur if you login at payhero.app - if you've used the company's direct domain, which would look something like company.payhero.app, then you'll be logged directly into that company.
Already Logged In
To change the PayHero company you're logged into, click on the company logo in the top right-hand corner of your screen and select the name of your current company. You'll be directed to the selection menu for you to switch to the company you wish to login to.
