The process of acquiring consumption data, aggregating it, adding necessary charges, and finally creating invoices for users is known as telecom billing. Receiving and recording payments from customers is also part of the procedure. Billing systems are sometimes referred to as accounts receivable since they aid in the collection of funds from clients. Revenue management aids in the prediction of customer behavior, which in turn aids in the improvement of product accessibility and price to maximize revenue. Global telecom operators and communication service providers (CSPs) have seen a considerable change in the number of end-users and their demands over the past few decades.
