The solution caters for online and offline real-time transaction processing; terminal management; card management; merchant, network, host or value-added provider settlement; reconciliation; and reporting. Transactions can be acquired from practically any source and can be easily routed to various authorization entities. Check/cheque authorizations can be performed, lowering costs and providing a high level of check management.

Flexible terminal management capabilities allow merchant acquirers to manage the entire terminal estate in a simple and consistent manner. Multiple terminal message protocols are supported on the same platform, using the same configuration tools.

Real-time and historical terminal monitoring capabilities allow for the provision of a high level of service to merchants operating the terminals. The same monitoring tools are used across different terminal protocol drivers.

Automatic transaction reconciliation facilities are available to allow reconciliation between different entities in the broader network in which the merchant acquirer participates. This also includes non-EFT entities, such as value-added solution providers. Postilion provides a flexible settlement solution that manages the entire merchant transaction processing cycle, from transaction settlement and payment through to billing and statement generation.

Interfaces to external systems are provided on several levels. Payment files are generated as part of the output of merchant settlement, as are general ledger posting files. These can be formatted to allow for full import into back-end accounting systems. Extracts of transaction data in any format are also supported for use in other systems.

A flexible reporting capability is supplied as standard. Several standard reports are available as part of the solution to facilitate management of the system, both financially and from a system perspective.
