The Settlement boundary handles the critical post-authorization processes of funds transfer, clearing, reconciliation, and merchant accounting. This domain comprises two major systems: FIBRE (Fintrax Invoicing, Billing and Reporting Engine) for invoicing and payment file generation, and MAS (Merchant Accounting System) for clearing and settlement calculations.

Applications

• FIBRE - .NET Core system for invoicing, billing, reporting, payment file generation
