will having 4 cashiers checking out customer orders using quickbooks be an issue?

Hello uservickitimmons,

Thanks for messaging us here. QuickBooks offers the versatility you need in order to manage your work with ease. I'll be glad to share more info so you can get back to doing what you love. 

The program allows you to add and manage users with ease. You can add your cashiers as users and they'll be able to access the account using their own login details. To learn more about this, I encourage you to check out the following article that shows you how to: Manage Users. 

Let me know if this info helps. I'll be one message away in case you have other questions.
