A Go library and HTTP server for reading, writing, and validating Automated Clearing House (ACH) files following Nacha standards.
What is ach?
Moov ACH is an open-source Go library and HTTP server for working with Automated Clearing House (ACH) files. It implements a reader, writer, and validator for ACH transactions, enabling developers to programmatically create, parse, and validate electronic payments according to Nacha standards. The project solves the need for a reliable, programmatic way to handle ACH files without relying on proprietary banking software.
Developers and engineers building financial applications, payment processing systems, or fintech platforms that require integration with U.S. banking infrastructure. It is particularly useful for teams needing to generate or parse ACH files for direct deposit, bill payments, or other electronic fund transfers.
Developers choose Moov ACH because it is a production-ready, open-source alternative to commercial ACH solutions, offering full Nacha compliance, a simple API, and the flexibility of self-hosting. Its modular design and active community support make it easier to integrate ACH processing without vendor lock-in.
