Awesome question! I'm so glad you asked, and I do apologize for the delay in getting back to you.
To get going, you can manage your cash drawer with the Square app on an iPad or Android tablet. You have the ability to "Open" and "Close" your cash drawer to check balances when you'd like. For more details, here is a link to our Support Center article that lays out how to get this set up.
As for your second question, Square doesn't have an official recommendation for the best way for tipping out employees. It really comes down to what works best for your individual business. Some merchants will tip their employees out each evening using cash. You have the ability to record "Pay Outs" using Cash Drawer Management (that's explained in the article referenced above). You can also view employee sales (including tips) from the Square Dashboard's Employee Sales report. Using this, you could pay tips out according to your regular pay schedule, and then just include this amount.
Hope this helps! Don't hesitate to add any other questions. I'm happy to clarify.
