We’ve been able to overcome industry challenges that have stalled other platforms. It’s been a true collaboration of expertise and flexibility.

Even with OMNIA Partners’ extensive reach as North America’s largest GPO, a significant portion of the public sector — specifically small and mid-sized agencies — struggled with systemic procurement inefficiencies:
OMNIA Partners selected Virto Commerce after a competitive evaluation of more than a dozen platforms. Virto stood out for its composable architecture, agile customization, and ability to support OMNIA’s complex multi-vendor, multi-agency procurement model. Virto Commerce also led the implementation in-house, ensuring full alignment with OMNIA’s unique requirements.
Together, they launched OPUS — a cloud-based ecommerce platform designed with direct input from procurement professionals and purpose-built for government buyers.
Key features:
OPUS has transformed how public agencies procure goods and services. Within just over a year of launch, the platform delivered measurable impact across the public sector and large infrastructure purchases — timeline reduced from 9–12 months to just a few weeks.
