Book excerpt: Welcome to the Green Book a comprehensive guide for financial institutions that receive ACH payments from the Federal government. Today, the vast majority of Federal payments are made via the ACH. With very few exceptions, Federal government ACH transactions continue to be subject to the same rules as private industry ACH payments. As a result, the Green Book continues to get smaller in size and is designed to deal primarily with exceptions or issues unique to Federal government operations.
