iMIS review
A broad association platform for teams that need membership and accounting in one system.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
iMIS is an association and membership management platform from Advanced Solutions International for associations, unions, nonprofits, and other member-based organizations. Its scope covers membership records, configurable billing, online joining and renewal, member portals, websites, communications, financials, events, certification, education, reporting, commerce, fundraising, CRM, CMS, and accounting. It is available through web and API access and is designed to support organizations managing several connected member operations rather than a single narrowly defined workflow.
The product’s strongest fit is its combination of membership and financial capabilities. Teams can manage recurring dues, automated renewals, member notifications, accounting, dashboards, and reporting alongside events and education programs. Online join and renewal workflows, portals, and websites extend those functions to members, while the REST API and web services provide options for extensions and integrations. Associations that want one platform spanning engagement, operations, and accounting should find this breadth relevant.
Pricing is structured around iMIS Professional for smaller organizations and teams, iMIS Enterprise for growing medium-to-large organizations and departments, and a separate one-time installation fee. Professional has a minimum of three users, while Enterprise pricing requires contacting sales. There is no free plan. iMIS should suit organizations that need configurable membership, billing, accounting, communications, and association-program management together. Smaller teams seeking a lightweight membership tool, or buyers who prefer transparent Enterprise pricing and no installation charge, may prefer a narrower alternative.
