“Can a decades-old IBM Power Systems ERP vendor remain the operating system for mid-market distributors by layering AI (IBM Watsonx, Proton) and best-of-breed finance integrations (Avalara, Stripe) on top of its S2K core?”
Vormittag Associates Inc. (VAI) is a long-established ERP software developer headquartered in Ronkonkoma, NY, focused on wholesale distribution, manufacturing, and consumer solutions (retail, service & repair, rental). Its flagship S2K Enterprise runs on IBM Power Systems and is offered both cloud and on-premise. VAI does not operate as an embedded-finance platform — it is a vertical ERP whose financial functionality (AR, AP, GL, fixed assets, customer portal payments) is delivered via third-party integrations with payment gateways (Stripe via Commercient), tax engines (Avalara), and other partners rather than through a proprietary BaaS/lending stack.
VAI processes payments through Stripe.
The Embedded Finance Index 2026 maps 2 layers in VAI's stack: Payments / PSP (Stripe); Tax (Avalara).
VAI is headquartered in Ronkonkoma, NY, USA.
