Sionic Debuts Instant Bank Pay and AI Fraud Detection on Microsoft Marketplace
By Lauren Towner · 13 August 2026

Quick Summary
Sionic has launched its Instant Bank Pay and AI-driven Fraud Detection services on the Microsoft Marketplace. By leveraging the FedNow Service and RTP network, the solution enables real-time, bank-to-bank transactions that reduce merchant costs by 60% compared to traditional credit and debit cards.
How Does Sionic Enable Real-Time Bank Payments?
Instant Bank Pay solves the high-cost burden of traditional card processing by facilitating direct account-to-account (A2A) transfers. By utilizing the FedNow Service and the RTP network, Sionic moves funds digitally within seconds from a consumer's checking account to the merchant's account. This bypasses the complex interchange web, resulting in an average 60% savings for businesses.
- Real-time settlement: Funds are available in seconds, not days.
- Cost efficiency: Significant reduction in swipe fees compared to credit/debit.
- Consumer incentives: Payers receive instant "Perks" for choosing bank-pay options.
What Role Does AI Play in Sionic’s Fraud Detection?
To address the historical lack of fraud detection and dispute resolution in real-time rails, Sionic utilized Microsoft Foundry to build advanced security layers. The service includes the first AI-based Fraud Detection Service (FDS) specifically designed to protect A2A payments at the point of sale. Furthermore, Sionic employs AI agents to handle refund negotiations between buyers and sellers, automating the dispute process and reducing the operational burden on financial institutions.
How Does the Microsoft Marketplace Integration Benefit Users?
The launch on Microsoft Marketplace provides a streamlined path for Microsoft Azure customers to discover and deploy Sionic’s payment solutions. This integration ensures that businesses can manage their payment infrastructure alongside their existing Microsoft cloud products with smooth deployment and unified management. Sionic’s presence in the marketplace signals a move toward widely accessible instant payments for the broader U.S. enterprise ecosystem.
FF NEWS TAKE:
Sionic’s move into the Microsoft Marketplace is a significant milestone for Instant Bank Pay adoption in the U.S. By solving the "missing pieces" of FedNow—specifically fraud protection and automated disputes—Sionic is making real-time payments a viable, low-cost alternative to the Visa/Mastercard duopoly. This isn't just a new app; it's a critical infrastructure layer that could finally trigger a mass shift toward account-to-account commerce.
