How do you collect rents?

[Bellman Tumasang]

Let's say my property rent not NOI is $1m a year.

All tenants pay online using an online service or app etc. 

I have a property management company that I pay 10% so $100k.

As the property management company manages the property like the leases, finding tenants, repairs, maintenance etc do they collect the $1m paid to their bank account and I trust that they only take a $100k cut and pay me $900k or can I instruct them to set up the online service where all the rents are paid to me so I pocket the $1m then pay them $100k?
