ACH ODFI
!
For ACH Debit Fraud see ACH Fraud/AML Prevention

Our API’s allows for ACH origination in 2 ways
1. Consumer Credits/Debits
2. Commercial Payments

Consumer Credits/Debits

Consumer Credits are enabled for externally verified accounts. We use data aggregator services from Envestnet Yodlee to OAuth into the end user’s external account and server to server communication, between Envestnet and our platform to transfer the Account and Routing Numbers. This ensures the most secure transfer of information and guarantees that the Account and Routing number have not been tampered with. Once an external account is linked the consumer is free to make ACH Credit Transfers for either Same-day or Standard ACH, in both cases the ACH Credit will have a pending hold on the Consumer’s Account until NACHA file is sent to the Fed, at which time the ACH Credit is settled on our virtual account.

Consumer Debits are also enabled through an externally verified account, however, these have a clearing period that is set up at the Product level, based on FinTech’s customer segment’s risk profile. There are separate clearing periods for Same-day ACH and Standard ACH

Commercial Payments

Commercial ACH Credits these typically occur for Payroll or Vendor Payment, and for commercial payments we allow for a Payee to be created that can be reused by the business and we manage the Payee information including name, account number and routing number for ease of use.

Commercial ACH Debits are typically Direct Debits that require the business to charge a business or consumer periodically. We allow for Recipients to be created for direct debits and enable the functionality at the Product level. The ACH Debits are still subject to the Same-day and Standard Clearing periods.

SEC Codes

ACH Fraud/AML Prevention

For ACH Fraud Prevention the platform uses multiple strategies to ensure that Fraud is being prevented through-out the ACH pipeline:

  • Instant Account Verification (IAV): For consumer ACH we ensure all external accounts have gone through verification, by OAuth. We do have failovers for Micro-Deposit Verification and Manual Verification through Banking Operations when required. No Consumer can add an Account and Routing Number without it being verified.
  • External Account Bank Funding Fraud (Optional): Based on the Product’s and the Product’s customer segment we can run the External Account credentials through Bank Funding Fraud which uses Early Warning System (EWS) for fraud detection.
  • ACH Debit Fraud Clearing: Every ACH Debit will be subject to a clearing period defined based on the risk profile of the customer segment for that Product. A different clearing period can be defined for Same-day ACH vs. Standard.
  • Real-Time ACH AML(Optional): On every Originated ACH we can run a real-time check for anti-money laundering and ensure that the recipient account has not moved to a sanction list since the last time the account was used.
  • Transaction Monitoring (Batched): The platform provides a data lake extract for use in any transaction monitoring system, for offline AML checks. If the Bank’s Compliance teams detect an issue with a Transaction, they then will block the account for further transactions until the investigation is resolved.
  • RDFI IAT OFAC Check: For all received international ACH’s the platform will run an OFAC check on the sender’s account to ensure they are not a Specially Designated National (SDN).
