About The Company

Welcome to Opsol Integrators and OmniPayments Inc.

Opsol Integrators was founded in 1995 as a specialist in porting open-source solutions to NonStop servers running under OSS (Open System Services).  Opsol is short for “Open Solutions,” and the company addressed customer interest in what was then the new development model of open source.  Nowadays, the NonStop architecture is even more “open,” thereby reducing the challenges once encountered to port Linux/Unix code. Yet considerations remain at times in mapping open-source solutions to the NonStop OSS architecture.  That’s when companies turn to Opsol, recognized in the IT industry as a leading HP NonStop system integrator. “OmniPayments History Article.” Opsol is known for fixed-price application development and for meeting our deadlines.  In fact, our team of 100-plus NonStop programmers can complete just about any project within six months.  We implement solutions from scratch, and we customize and enhance existing system components to operate cost-effectively, more efficiently, and with less risk. Our professional services include architecture design and reviews, programming, web integration, quality assurance, staff training, production, and deployment.  We build applications on all NonStop platforms, including NonStop X.  From our seven worldwide locations, we serve as a 24×7 managed services provider for remote production monitoring. Those same custom development skills allowed Opsol Integrators to create the popular OmniPayments financial-transaction switch.  Now produced by OmniPayments, Inc., Opsol’s product arm, OmniPayments has proven itself to be an attractive BASE24 replacement for customers impacted by ACI’s sunset of BASE24 on NonStop.  A typical migration from BASE24 to OmniPayments takes about four months, and the transition is pain-free.

Management Team

Yash Kapadia


When CEO Yash Kapadia left his tenure as a developer at Tandem Computers, he did not abandon the NonStop platform. Instead, he founded Opsol Integrators, whose team is known worldwide for successfully completing mission-critical custom integration projects on time and well within fixed-price requirements. At Tandem, Yash participated in numerous assignments for customers such as Wells Fargo, United Airlines, and John Deere. Yash’s experience with the financial and retail industries led to the creation of OmniPayments, a financial-transaction switch that runs on NonStop but easily ports to open-source applications.
