Customers frequently need an end-to-end picture of the status of their transactions. Payment and trade trackers are two examples of useful features that give users up-to-date information on the status of their transactions in real time. They are able to see, for example, whether the transaction is awaiting approval from a person in their organization, and how many more authorization levels are required before it reaches the bank’s processing queue, or whether the bank needs any further details, due to the additional due diligence required. The transaction can be returned for more documents/validation or data if the bank requests them, facilitating easy communication.
In the current climate, where multiple regions require heightened security and compliance inspections, this is especially crucial. In addition to reducing the need for manual intervention, having a robust two-way communication process gives the consumer a more efficient and fulfilling experience by giving them a sense of information and control throughout the process.
Users should be able to see the acknowledgment status of the networks as well as SWIFT communications related to their transactions. With the help of this feature, customers may keep an eye on whether their money has been handled properly by their bank and has reached the receiving bank, providing a clearer picture of the transaction’s path.
Users can feel more assured that their money has been transferred correctly and on schedule when they have access to this level of information. It contributes to a more seamless and informed banking experience, by reducing uncertainty, decreasing the need for updates from the bank, and increasing transparency. This functionality is critical for businesses managing large or international transactions, when confirming the recipient bank’s receipt of the funds.
