There are various reasons why ACH transfers should be used instead of wire transfers:
Cost-Effectiveness: ACH transfers generally have lower transaction fees than wire transfers, making them more cost-effective, especially for frequent or low-value payments.
Non-Urgent Payments: ACH transfers are suitable for non-urgent payments that dont require immediate availability of funds. They work well for recurring payments or situations where the transaction speed could be more critical.
Domestic Transactions: ACH transfers are designed for domestic transactions within the United States and are commonly used for payments involving U.S.-based financial institutions and accounts.
