Property Management - When and how do they charge their % ?

[Xela Batchelder]

I have my first property manager for one unit.  This is the second month this tenant has been in there, and he hasn't paid yet 21st of the month.  However, it is normal for the Property Management Company to charge the 10% on the first of the month if they get the rent or not?  My new property management company charged me the 10% on the first of the month (which I paid).  So just wondering if this is normal or not.
