In the business world, there is frequently a delay between the time services are delivered and an invoice is created and when the payment is collected when it comes to charging a customer for labour or services. However, these delays create spaces where errors or mistakes in billing and collecting money may occur. Revenue leakage may affect operators who rely on latent CDRs (call detail records). The cost to telecom carriers of these errors or delays in the charging feature is frequently quite high. However, real time charging system solutions can guarantee that every subscriber transaction is recorded and handled in real time.
