Abstract: A system manages payments by an entity to its partners (suppliers, service providers, etc.) by providing an intermediary capability to disaggregate and regenerate payment orders using real time inputs from the payee. A single obligation may be split into different payments to different institutions and payment vehicles such as prepaid cards, countries, and currencies. An Al predictive function may reduce foreign currency transfers and their associated costs by recognizing intra-divisional, intracompany and intercompany assets and liabilities to allow in-country net settlements to be made prior to using a foreign currency transfer. When needed, foreign currency transfers may be aggregated to reduce the volume and velocity of those transfers. Tokenization of financial data and accounts may further protect activity between payors, payees, and financial institutions.
