Nexus Systems delivers its applications through the internet as a standard Application Service Provider (ASP).Organizations choose how and where its NexusPayables application is hosted.  Organizations can host the application (self-hosted option) or have Nexus Systems host and manage your application (Nexus-hosted option).

Self-Hosted Option

Nexus Systems recognizes that ASP-delivered software is not right for everyone. That is why we offer a self-hosted solution. Self-hosting requires additional hardware and software, but organizations benefit from standardized software versions, scheduled upgrades and superior customer support.

Nexus-Hosted Option

Nexus Systems offers a completely staffed, managed, backed-up and monitored 24/7, 365 days a year hosting solution for its NexusPayables application. This option includes the necessary hardware, software, database and data storage to support each organization’s application.


Nexus Systems utilizes Rackspace®, a global leader in managed cloud services, as the backbone of our hosting option.  Our cloud services partner, Rackspace®, provides a fully managed service facility with more than 200,000 customers in 120 countries and produces $1.5 billion in annual revenue. It hosts more than 60% of the Fortune 100 companies and 62% of the companies who advertise during the Super Bowl. To learn more about Rackspace®’s impressive infrastructure, please visit
