Lerian Matcher

What Lerian Matcher is

Lerian Matcher automates reconciliation among financial transaction sources by scoring matches, routing exceptions, and keeping an audit trail. It supports exact and tolerance matching, date windows, multiple currencies, and split or aggregate matching, with confidence scores from 0 to 100. Matches scoring 90 or above are confirmed automatically except fuzzy matches; lower-scoring and unmatched items go to a review queue. Users can classify, assign, and track exceptions, then force a match, create an adjustment, or open a dispute. An append-only log records configuration changes and exception resolutions. Matcher accepts CSV, JSON, XML, ISO 20022 camt.053, CNAB, OFX, and acquirer EDI files. It can reconcile data from banks, ERPs, payment processors, and other sources independently, with optional connections to Lerian's Midaz, Reporter, and Flowker products. The API covers reconciliation contexts, sources, and matching rules. Documented deployment uses PostgreSQL, Redis, and RabbitMQ, with Docker or Kubernetes options. Matcher is available to licensed customers, and pricing is on request. Its documented default limit is 100 MB and 100,000 transactions per file; the file-size limit can be configured. The product site offers a file-based proof using masked data.
