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:
Day 1: The debit (first leg) processes on the first banking day
Days 2-3: Two-day hold period after successful debit
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.
