For years, iMIS has been the default platform for associations evaluating their technology options. Purpose-built for membership administration, it became deeply embedded in how industry bodies, professional associations and membership organisations operate. For a long time, it was one of the only credible options available.
That is no longer the case.
hubAMS, built on HubSpot, has emerged as a modern alternative for associations that need membership management, renewals, events, CPD, reporting, automation and engagement to work together in one connected environment. It handles the operational requirements associations expect from an AMS, while also bringing in the CRM, marketing automation and lifecycle visibility that legacy systems were never originally built to deliver.
For associations weighing up iMIS and hubAMS, this is a direct comparison across the areas that matter most.
Membership management is the operational core of any association platform. Membership fee processing, tiered structures, renewals, event and course registrations, CPD tracking and member self-service all need to work reliably. This is where iMIS has historically been strongest, and any honest comparison has to start there.
iMIS was purpose-built for association administration. Decades of association-specific operational requirements have been baked into the platform, and for complex membership models, that depth is real.
Membership fee calculations, CPD compliance workflows, financial reconciliation and traditional association administration are all areas where iMIS has long been used as the operational backbone.
hubAMS covers the same operational ground inside HubSpot. It was built specifically to give associations the membership management layer they need while keeping membership data connected to engagement, communications, events and reporting.
hubAMS supports tiered membership management, complex membership structures, automated renewal workflows, billing cycles, payment processing, event ticketing and registrations, member self-service portals and CPD tracking inside the HubSpot environment.
The critical difference is architectural.
In iMIS, membership data lives in a system designed primarily for administration. In hubAMS, membership data lives inside HubSpot, the same platform used to manage engagement, marketing, reporting, renewals, events and member communication.
That means one record, one source of truth and no constant movement of data between the AMS and the CRM.
iMIS was built for administration at a time when administration was the primary need. Its marketing capability reflects that. Renewal notices, basic event communications and simple email sends are possible, but meaningful segmentation, behavioural automation and personalised member journeys are not where the platform is strongest.
In practice, many associations running iMIS still rely on a separate email or marketing platform alongside it, often supported by exports, imports or manual list management.
The result is a membership team spending significant time managing data movement rather than member engagement. Campaigns require exporting lists before anything can be sent. Segmentation is often limited to basic membership type or demographic filters. At-risk members need to be identified manually. Personalisation beyond basic fields can be difficult to achieve at scale. Email performance data and membership data often struggle to connect back to a single live record.
Because hubAMS is built on HubSpot, engagement and marketing automation sit at the centre of the operating model rather than being added later.
Associations can segment members by renewal risk, engagement score, event attendance, tenure, tier, region or any custom property without needing a spreadsheet. They can trigger workflows based on real member behaviour, such as inactivity, an approaching renewal date, event attendance, content engagement or changes in membership status.
Personalised onboarding, renewal and re-engagement journeys can be built around how members actually interact with the organisation. Event campaigns can target members based on historical behaviour. Every email open, portal login, event registration, renewal and form submission can contribute to the same member view.
When a member renews, the record updates. When they register for an event, it updates. When they engage with an email, it updates. Engagement data and operational data sit in the same place, in real time.
Every association needs a website that works. It needs to look credible to prospective members, be easy for non-technical staff to update and connect properly to the membership data behind it.
This is where iMIS often compounds its own problems.
RiSE is the built-in CMS for iMIS and has historically been a common frustration for associations. Many organisations eventually move their website onto WordPress or another CMS simply to create a site their team can manage more easily.
That creates another layer of fragmentation. iMIS handles membership, the website sits elsewhere, and the connection between the two often requires additional management.
Common challenges include rigid templates, limited design flexibility, a clunky editing experience, dated front-end output, limited SEO capability and member portal functionality that can be difficult to customise.
For associations trying to improve digital experience, the website often becomes another reason to reassess the wider platform.
With hubAMS, the website, CRM, marketing tools and membership management environment all sit within HubSpot.
HubSpot CMS gives associations a modern, staff-friendly website platform with drag-and-drop editing, SEO tools, forms, analytics, conversion tracking, hosting and personalisation capability built in.
Smart content can personalise the website experience for different audiences. A logged-in member can see different content from a prospective member. Forms can feed directly into HubSpot workflows. Website activity can become part of the member engagement record.
The website stops being a disconnected front door and becomes part of the member journey.
Good decisions require good data. For association leadership trying to understand membership health, renewal trends, event performance and engagement, reporting quality directly affects how confidently the organisation can operate.
iMIS reporting covers the basics: membership numbers, renewal rates, event attendance and financial summaries. Beyond that, producing a meaningful view of membership health can require exports, manual reporting and additional tools.
Many associations supplement iMIS reporting with Excel, Power BI or other business intelligence tools because the native reporting environment does not always provide the real-time, cross-functional visibility leadership teams now expect.
By the time the report reaches the board or CEO, it may already be historical. Combining membership, events, marketing and finance data often requires manual work.
hubAMS uses HubSpot reporting to bring membership, engagement, events, revenue and communication data into one live environment.
Because operational membership data and HubSpot engagement data share the same record, associations can build dashboards showing renewal rates, engagement trends, at-risk members, event attendance, revenue and campaign performance from a single source of truth.
Leadership teams can see which member segments are at risk, which events are influencing engagement, which campaigns are driving renewals and how membership performance is trending over time.
No exports. No manual stitching. No report that was accurate three weeks ago but already out of date today.
Association needs evolve. Membership models change, new revenue streams emerge and member expectations shift. The flexibility of the platform underneath determines how easily the organisation can adapt, and how much that adaptation costs.
iMIS workflows are shaped by the platform’s long-standing association administration model. When that model aligns with how the association operates, it can work well.
When the organisation needs to adapt, the process can become slower. New membership tiers, revised renewal processes, different commercial structures or updated workflows may require vendor support, specialist knowledge or development time.
The platform can be configured, but it is not generally known for the kind of rapid, team-led iteration associations increasingly expect from modern SaaS platforms.
HubSpot’s workflow engine is one of the major advantages of hubAMS.
Internal teams can build, modify and test workflows using a visual interface, without needing developers for every operational change. New automations can be launched quickly, then refined as the team learns what works.
hubAMS allows membership workflows to reflect how the association actually operates, while HubSpot continuously expands its automation, reporting and AI capabilities.
For lean teams, that difference matters. The platform becomes something the organisation can actively improve, not something it has to wait in line to change.
No association runs on a single platform. Finance tools, payment processors, event systems, communication platforms and reporting tools all need to connect reliably.
iMIS was built before modern integration ecosystems became the operating standard. Connecting it to newer tools often requires custom API work, specialist knowledge and ongoing maintenance.
Many associations end up with a patchwork of systems connected by imports, exports and manual processes. The total cost of maintaining a well-integrated iMIS environment can become significantly higher than the licence cost suggests.
HubSpot was designed to operate as the central hub of a connected technology stack.
It offers a large marketplace of integrations, native connections with common tools and a well-documented API for custom requirements. Because hubAMS runs inside the HubSpot environment, the most important integration point, the one between the AMS and CRM, is removed entirely.
Memberships, engagement, reporting, events and communication already sit together. The organisation is no longer trying to keep its AMS and CRM in sync because hubAMS brings the AMS layer into HubSpot.
The best platform delivers limited value if the people using it every day find it frustrating, slow or difficult to understand. User experience affects staff adoption, operational efficiency, member satisfaction and the return an organisation gets from its technology investment.
iMIS carries many of the design conventions of its era. It is functional, but it reflects a time when enterprise software prioritised feature depth over usability.
For teams accustomed to modern SaaS tools, the day-to-day friction can be real. Training requirements are often higher, self-service experiences can feel dated, and the member-facing portal may not meet the expectations members now have from digital platforms.
HubSpot invests heavily in usability, and that becomes a major advantage for associations using hubAMS.
The interface is clean and consistent across the platform. Marketing, membership, events, leadership and service teams can work within the same environment without needing to become specialists in a complex AMS.
Member self-service portals can also be designed to modern standards, which matters because self-service only reduces admin if members actually use it.
When staff adoption improves, data quality improves. When data quality improves, reporting and decision-making become stronger.
Neither platform is plug-and-play, and being upfront about that matters.
iMIS implementations require specialist knowledge of the platform, its architecture, its data model and its configuration options. That expertise exists, but it sits within a narrower ecosystem of specialists.
Getting iMIS configured correctly can be a significant undertaking, and long-term reliance on a smaller specialist pool is worth considering as part of any platform decision.
hubAMS also requires the right implementation partner, particularly when migrating from a legacy AMS. Membership architecture needs to be designed properly, data needs to be migrated cleanly, workflows need to reflect how the association actually operates and teams need to be trained across functions.
The distinction is the ecosystem.
HubSpot has a large and growing partner network, strong documentation, ongoing platform investment and a broad pool of professionals familiar with its CRM, CMS, automation and reporting environment.
For associations moving to hubAMS, that creates a more sustainable implementation and support path over time.

For some associations, iMIS may still be the right fit. If an organisation is heavily invested in the platform, has stable processes, strong internal expertise and primarily needs mature association administration, the case for staying may be valid.
But for many associations reassessing their technology stack, the friction is already visible.
The manual exports before a campaign can go out. The spreadsheet that bridges the membership system and the email tool. The membership health report that takes days to produce and is already dated by the time leadership sees it. The workflow change that requires a support ticket and a wait.
iMIS was the right answer for a different era of association management.
The expectations of members have shifted, the tools available have advanced and the gap between what legacy systems provide and what associations now need has become harder to ignore.
hubAMS, built on HubSpot, represents where association management is heading: a single platform where the operational layer and the engagement layer share one record, real-time visibility is the default, and the platform continues to evolve rather than standing still.
