What it means
The Automated Clearing House is a batch network governed by Nacha rules and operated by the Federal Reserve and a private operator. Your funder does not touch your bank directly. It instructs its own bank (the originating institution), which submits a batch that settles at your bank (the receiving institution).
Two properties of the network shape how funding works. It is batched, not instant, so entries are collected and processed at set times rather than continuously. And it runs on banking days, so weekends and federal holidays are skipped. That is why daily MCA payments are really banking-day payments and why a Friday funding often lands Monday.
Entries carry a code describing the type of authorization. Business-to-business debits usually go as CCD, consumer-style debits as PPD or WEB. The code matters because the return rights attached to it differ, and business codes carry a much shorter window to dispute an unauthorized debit.
Failed entries come back with a return code: R01 for insufficient funds, R08 for a stop payment, R10 or R29 for unauthorized. Funders read those codes as underwriting signals, and repeated returns typically trigger fee and default clauses.
Where this one catches people
ACH is not a payment guarantee. Settlement is provisional; a debit that appeared to clear can be returned days later, and an entry your bank shows as pending can still fail. Funders that treat ACH as instant get returns; borrowers who treat a pending debit as final overdraw the account.
Worked through
A funder submits a daily debit on Thursday for Friday settlement. Friday is a federal holiday, so nothing settles until the next banking day. The account is debited Monday, and if a Tuesday debit is already queued, two payments hit within roughly 24 hours.
