Is credit and accounts receivables management one of the main objectives of the credit control Manager?

There is a difference between credit and management of receivables, this does not mean that they are not the main objective, but they are the main objective as the oversight role of credit lies in the completion of credit transactions on the basis of standards forcing the customer to pay the receivables due from him, and lies role also in the control of the legality of the transaction so that the positionour legal terms of the signed papers and in terms of completeness.
I hope I have answered your question so as to achieve what you mean Thank you

The main objective being to monitor a business cycle & to meet routine business requirements.

Credit Control is the process of limiting the credit to bad risk clients and extending to credit worthiness clients.
Monitoring the receivables and having your employees effectively collect the debts is where the management part comes into play.
