A real-time third-party payment system accepts payments to a lender from third-party merchants in real-time. The payment system may receive real-time payment information from the third-party, and various services within the payment system validate the customer account information, create a payment, store the payment in a database, and post the payment to a real-time ledger. The payment system may also receive an end-of-day file including file-based payment information. The file-based payment information may be verified against the real-time payments stored in the database. Upon validation, the payment system creates a file based payment and posts the file-based payment to a file-based ledger. The payment system may detect fraud, errors, and other discrepancies in real-time payments and make corrections based on settlement rules and self-healing rules provided by the third-party.
