Processing times on Abacus take 8 business days at most. Our customers typically see their reimbursements hit their bank account within 3 business days of an expense approval.
Payments on Abacus are processed using 'ACH' — a network that all US banks support. If you've ever set up direct deposit for your paycheck, you've used ACH.
ACH processing times vary quite a bit. Even though the process is entirely electronic and automated, ACH batches don't run on weekends or bank holidays. ACH debits (from the organization to us) typically take 4-5 business days, and ACH credits (from us to you) typically are next day.
