About
iMIS is an association management system (AMS) and engagement management system (EMS) developed by Advanced Solutions International (ASI), headquartered in Washington, DC. With over 4,000 association customers worldwide, iMIS has been one of the most enduring platforms in the association technology market, serving member-based organizations for over 35 years. The platform provides membership management, dues and billing, event registration, certification tracking, fundraising, committee management, and a member-facing web portal built on the iMIS RiSE content management framework.\n\nA distinguishing characteristic of iMIS is its positioning as an Engagement Management System — a concept ASI has promoted to emphasize that the platform tracks not just transactional membership data but all forms of member engagement including event attendance, committee participation, online community activity, and learning completions. This engagement scoring approach helps associations identify at-risk members and target renewal and upgrade campaigns more intelligently.\n\niMIS is available in cloud and on-premise configurations, which gives it flexibility that newer cloud-only competitors lack for associations with specific data residency or infrastructure requirements. The platform also has a robust partner ecosystem and API framework that enables deep integrations with Salesforce, accounting systems, and specialized association tools. Its longevity and global install base — including many large international associations and institutes — represent a significant barrier to competitive displacement.
