C3 review
A mature HOA operations platform focused on accounting, budgeting, and maintenance workflows.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
C3 is Advanced Technology Group, Inc.’s community association management software for management companies and self-managed associations. Its core coverage centers on financial and operational workflows, including financial management, accounts receivable and payable, budgeting, reporting, delinquency processing, association management, work orders, maintenance management, architectural management, and covenant tracking. Cloud access, web availability, Android support, online dues through ATG Pay, maintenance requests, and accounting tools position it for organizations managing day-to-day association administration.
Pricing is offered through a contact-sales model rather than a published plan structure. That approach may suit management companies and associations that want a conversation around organizational needs, but buyers will need to engage Advanced Technology Group to understand the commercial fit. The available product details do not establish separate tiers or a self-service subscription path, so C3 is better suited to buyers prepared for a sales-led evaluation than to teams comparing transparent online plans.
C3’s strongest distinction is breadth across financial control and operational follow-through. It connects accounting-related work with budgeting, receivables, payables, delinquency processing, work orders, maintenance, architectural management, and covenant tracking. The product is also positioned for growing management companies and smaller self-managed associations, with cloud access designed to provide user access to community data. Its ecosystem is centered on TownSq, while its platform coverage includes web and Android. Choose C3 when mature financial management is the priority alongside maintenance and governance workflows. Consider another option if your selection depends on a wider integration ecosystem or a broader resident-facing feature set.
