Control and ledger account

The control account is a ledger account (it is in the nominal.general ledger).

I think what you are really asking is what is the difference between the Receivables ledger control account, and the receivables ledger.

The receivables ledger control account records total receivables and is part of the double entry. The receivables ledger is a book containing accounts for each individual customer, and is not part of the double entry.

This is all explained in full (with a full example) in my free lecture on Books of Prime Entry.
