Notes from the integration desk, not a newsletter.
Written by whoever on the team had something worth documenting, usually right after a client conversation surfaced a question we hear often.
Instant payments are irrevocable, and that changes everything about fraud response.
Unlike ACH, which allows a window for reversal, FedNow and RTP transactions settle with finality in seconds. That's the entire point for a legitimate payment — but it means fraud controls have to catch a bad transaction before it sends, not after. A bank's existing fraud rules built around ACH's reversal window often don't transfer cleanly to an environment with no do-over.
Liquidity management is the part nobody budgets enough time for.
FedNow's Liquidity Management Transfer tool exists precisely because 24/7/365 settlement creates funding needs that don't respect business hours. Institutions that treat this as a checkbox rather than a genuine operational redesign are the ones that end up improvising at 2 a.m. on a holiday weekend, which is exactly the scenario the tool was built to prevent.
A sponsor relationship is a real business decision, not just a technical shortcut.
Connecting through a sponsor bank gets a smaller institution live faster, but it also means depending on that sponsor's own risk appetite, pricing, and operational choices. We walk every client through what direct connectivity would look like later, even if sponsorship is the right starting point now.
ISO 20022 is more structured than what most core systems produce today.
The message standard both FedNow and RTP require carries far more structured data than a typical ACH file — richer remittance information, clearer party identification. Mapping to it well is less about the technical translation and more about deciding what to do with all the additional data your core system was never asked to capture before.
Weighing whether FedNow, RTP, or both make sense for your institution? Get in touch — that's usually how the first conversation starts.
