How does Standard ACH settlement work?

Last updated: December 16, 2025

Context

Merchants often want to understand the timeline for a Standard ACH transaction and when funds will be available in recipient accounts.

Answer

GrailPay Standard ACH follows a 4-banking-day settlement process with specific timing rules:

Settlement Timeline:

  1. Day 1: The debit (first leg) processes on the first banking day

  2. Days 2-3: Two-day hold period after successful debit

  3. Day 4: Payout (second leg) is initiated

Key Processing Rules:

  • ACH batches are processed daily at 5:30pm ET

  • Payments created after 5:30pm ET roll over to the next business day

  • ACH does not process on weekends or holidays

  • Individual bank policies may and often will affect final fund availability timing

Example Timeline:

If a payment is created at 7:22pm ET on Tuesday:

  • It effectively processes Wednesday (missed Tuesday's 5:30pm cutoff)

  • Debit settles Thursday (Day 1)

  • Hold period: Friday and Monday (Days 2-3)

  • Payout initiated Tuesday morning (Day 4)

  • Funds typically available Tuesday or Wednesday

Important Note: Even after GrailPay completes the payout to the recipient bank, individual financial institutions may have their own policies that affect when funds become available in the account.
