What Accounting System Integrators does

Accounting System Integrators (ASI) is a privately held, North Haven, Connecticut-based Acumatica Value-Added Reseller (VAR), Independent Software Vendor (ISV), and Developer founded in 1991 (firmographic year listed as 1993) by Bill Dean, who remains Founder & CEO. Originally a reseller of Solomon Software serving both for-profit and nonprofit clients, ASI pivoted in 2008 to the Acumatica Cloud ERP platform and has operated for 15+ years as a vertical specialist serving nonprofit organizations exclusively. The company operates with 1–10 employees from its sole U.S. office at 280 State Street, Suite 203, North Haven, CT, under the legal entity Accounting Systems Integrators LLC.

ASI's product architecture is built on a hybrid of Acumatica platform resale plus proprietary native extensions. The company resells the core Acumatica Cloud ERP — including Financial Management (General Ledger, Cash Management, AP, AR, Expense Management, Fixed Assets, Time, Currency, Reporting/Power BI integration with 17,000+ bank feeds) and Procurement Management (Requisitions, Purchase Orders) — and layers its proprietary NonProfit+™ nonprofit accounting suite on top, which delivers fund accounting, grant management, program management, budget management, and encumbrance accounting. ASI further extends Acumatica through its AcuAddons suite (Distribution Codes, Advanced Import, Historical AP and AR, Advanced Expense Management, Advanced Integration) and operates the AcuCademy eTraining platform (13 courses, 200+ quizzes) for nonprofit ERP enablement. Trademarks are registered for NonProfit+™, AcuCademy, and AcuAddons.

ASI's business model combines recurring subscription revenue (Acumatica and NonProfit+ license resale) with professional services revenue (full-lifecycle implementation, data migration, and training) on quote-based, multi-year contract structures with no publicly disclosed pricing. Go-to-market is dual-channel: direct consultative sales to nonprofit organizations through website-driven demand generation (Request Information / Request Demonstration forms), complemented by distribution through a network of certified Acumatica resellers that extend NonProfit+ reach beyond direct coverage. Customer segmentation is strictly vertical — nonprofit organizations with specialized fund-accounting, grant-lifecycle, and regulatory compliance needs.
