## Affects

***

Teams evaluating or integrating automated transaction reconciliation.

This update applies to the public documentation portal. It does not change the runtime API behavior unless the linked product documentation says otherwise.

## What changed

***

This release introduces **Matcher**, Lerian's automated transaction reconciliation platform. Matcher reconciles transactions across any data sources—internal systems, banks, payment processors, ERPs, or payment gateways—using configurable rules, confidence scoring, and complete audit trails.

### What is Matcher?

***

Matcher is a **reconciliation engine** designed to automate transaction matching across multiple data sources. You configure matching rules once. Matcher handles the repetitive work—matching transactions, flagging discrepancies, and maintaining audit trails for compliance.

### Key capabilities

* **Automated matching** — Exact or tolerance-based rules with confidence scoring (0–100)
* **Multiple data sources** — Reconcile banks, ERPs, payment processors, and ledgers simultaneously
* **Exception management** — Route unmatched items to JIRA, ServiceNow, or your own tools
* **Compliance-ready** — Immutable logs and SOX-ready reports for audits
* **Split and aggregate** — Handle 1:N, N:1, and N:M transaction relationships
* **Multi-currency** — Reconcile across currencies with FX rate handling
