Software Unlimited

What Software Unlimited does

Software Unlimited, Inc. (SUI) is a privately held vertical SaaS company founded in 1979 and headquartered in Sioux Falls, South Dakota. It develops the School Accounting System, a fund accounting suite purpose-built for K-12 school districts, with state-specific reporting customizations for nine contiguous Midwest and Northern Plains states: Idaho, Illinois, Iowa, Kansas, Missouri, Nebraska, North Dakota, South Dakota, and Wyoming. The platform covers General Ledger, Payroll, Accounts Payable, Fixed Asset Inventory, Human Resources, employee Negotiations, Accounts Receivable, Report Writer, Census, and a Web Link employee portal, complemented by K12Docs, a cloud-based electronic document management module. Technology is built on a Windows-based SQL database with both on-premise installation and a cloud-hosted SaaS deployment (School Accounting System-Online), and nearly 250 of roughly 1,200 customer districts have migrated to the cloud.

The company sells directly to school districts through a small sales team led by a Territory Sales Manager and Partner Corey Atkinson, supported by an inside sales function that answers more than half of inbound calls with a live representative. Go-to-market is heavily event-driven, with active participation in ASBO International and the nine state-level school business official associations, supplemented by a quarterly newsletter (SUI Quarterly), an extensive webinar program, and a 30-day free trial attached to every license. Pricing is quote-based annual subscription with modular add-ons, and as of August 2025 the Human Resources module is bundled at no additional cost.

Software Unlimited is founder- and partner-owned with no disclosed institutional investors or parent company. Leadership consists of three partners — TJ Chaplin (Chief Technology & Financial Officer, with the company since 1982), Amy Feit (Chief Customer Officer, since 2004), and Corey Atkinson (Chief Business Officer, since 2003) — following the 2022 retirements of co-founder Tom Chaplin and CEO Pam Derheim. The firm employs approximately 30 people, including software developers, trainers, customer support representatives, quality assurance analysts, new school coordinators, and administrative staff, with several long-tenured employees. The company maintains no disclosed funding rounds, M&A activity, patents, or AI/ML capabilities.
