What is equivalent of EBS Territory management in Cloud

Summary:

I am looking for a way to tie the customers to salesrep hierarchy. In EBS there was sales territory assignment that can be based on FIPS/Zip code.
In CRM foundation and assign the territory on the order line.

in Cloud, there is sales credits and salesperson on the order header.
is there any OOTB functionality/documentation around sales territory mgmt in cloud and how customers are assigned salesrep and hierarchy.

Or create DFFs on customer account for this purpose?
can you please re-direct to correct forum? Thanks
