Extending Customer Accounts in AR module by using Extensible Flexfields

Summary:

We are using out of the box Oracle cloud AR module. We would like to capture our billing requirements as well by extending the customer accounts table using Extensible Flexfields to incorporate multiple options if the same account needs different documents during invoicing - a separate sub entity to capture a specific set of requirements for different documents.

I’m looking for mustard color entities in the out of box AR module either in the form of extensible Flexfields or similar relationship between hz_cust_acct_sites_all and hz_cust_accounts. Consultants are proposing to use Customer Data Management outside ERP pod to incorporate the billing requirements, instead of using AR module. I’m looking for guidance from experts on whether we can use AR module to achieve what we want instead of standalone POD for customer accounts to capture more than what Oracle provided in out of the box table.
