iMIS vs ReadyMembership: the modern alternative for membership organizations
iMIS vs ReadyMembership: the modern alternative for membership organizations
If you're evaluating iMIS — or you're already on it and wondering whether there's a better fit — you're not alone. iMIS is a long-established platform with a loyal following, and it does many things well. But for professional associations and membership organizations looking for a more intuitive, unified system that their whole team can use from day one, ReadyMembership is increasingly the alternative of choice. This page sets out an honest comparison so you can make the right decision for your organization.
Who is this page for?
Whether you're a Membership Director frustrated by reporting complexity, an Executive Director building a business case for change, or an operations lead spending too many hours on manual workarounds, this comparison is written for you. ReadyMembership is purpose-built for professional associations, trade bodies, and membership organizations — the organizations where every hour saved matters.
Where iMIS and ReadyMembership overlap
Both platforms are built specifically for membership organizations. Both offer membership management, event management, a CRM, reporting, and integration capabilities. Both are cloud-based and support complex membership structures. If you are evaluating either platform, you are broadly in the right space.
The question is not whether iMIS works. For some organizations, it works very well. The question is whether it is the right fit for yours — and whether the investment in time, cost, and internal expertise required is proportionate to what you get back.
Where ReadyMembership offers a different approach
Ease of use and day-to-day administration
iMIS is a powerful platform, but reviewers consistently flag a steep learning curve and the need for dedicated technical expertise or external consultants to configure and maintain it. On G2, iMIS scores 7.5 out of 10 for ease of use and 6.7 for ease of setup. ReadyMembership scores 8.5 and 7.7 respectively across the same criteria — reflecting a platform designed to be used confidently by membership professionals, not just IT teams.
For a small or mid-sized association, that difference in usability translates directly into staff time, training costs, and how quickly your team can actually get things done.
A genuinely unified platform
iMIS offers strong core functionality, but users regularly report that events, advanced email marketing, and the web CMS sit outside the main system or require additional modules and third-party solutions — each with its own cost and integration overhead.
ReadyMembership brings your CRM, website, email marketing, events, communities, reporting, and eCommerce together in a single platform with a single view of your data. There is no need to sync systems, manage separate logins, or reconcile data across tools. As Ana Christie, Chief Executive of Sussex Chamber of Commerce, put it: "Immediately, the fact that the CRM, CMS, as well as Marketing are linked was a huge win for us."
Built-in AI, not bolted on
ReadyMembership includes ReadyIntelligence — an AI assistant that allows your team to query membership data in plain language, surface insights, and automate routine tasks. AI is embedded across the platform, from personalization rules to predictive analytics, rather than offered as a separate, additional-cost layer.
Reporting that works for your whole team
One of the most consistent frustrations with legacy AMS platforms — including iMIS — is reporting. Users describe needing SQL knowledge to run custom queries, missing data fields on exports, and having to work across separate systems to get a complete picture. ReadyMembership gives every member of your team access to configurable dashboards and real-time analytics, without needing a developer in the room.
Member community, built in
iMIS relies entirely on third-party integrations for community features — typically Higher Logic — which means an additional cost, an additional contract, and another data sync to manage. ReadyMembership includes native Groups built into the platform, so members can connect, share resources, and engage through dedicated community spaces without bolting on a separate tool. For organizations where member engagement and peer connection are central to the value proposition, that difference matters.
Implementation that doesn't require a consultant
iMIS is highly customizable, but that customizability comes with a dependency on implementation partners and ongoing consultant support that can significantly add to the total cost of ownership. iMIS pricing starts at $200 per user per month, but the real cost is what surrounds it: specialist consultants, extensive training, ongoing customization support, and third-party integrations routinely push total cost of ownership to $150,000 or more in year one alone. ReadyMembership's implementation and licensing costs are more predictable from the outset — and there are no hidden consultant fees to make changes your team could handle themselves. As Amber Shaverdi Huston, Executive Director of NACA, said: "When a company really knocks it out of the park, they hear a question, think about it, then think ahead about other potential problems and implications."

What membership organisations achieve with ReadyMembership
These are real outcomes from associations that made the switch to a modern, unified platform.
What our clients say
It’s great that ReadyMembership is all-in-one. So much is automated, helping us streamline our processes, save time and reduce costs. This allows us to focus on developing our business membership offer.
We’re a small team and so we wanted a technology supplier that can increase our productivity by reducing manual tasks, giving us a single view of our data, and segment and personalise communications our members’ receive based on their interests and interaction with us – driving better member engagement.
We don’t use the word ‘transformation’ lightly. But that’s what it was. It wasn’t just a tech project—it redefined how we operate and how we’re perceived.
Is ReadyMembership right for your organisation?
ReadyMembership is the strongest fit for professional associations, trade bodies, and membership organizations that:
- Have a team of staff managing an active membership base
- Are frustrated by fragmented systems, manual data management, or poor reporting visibility
- Want a platform their whole team can use confidently, not just their most technical person
- Are looking to grow membership, improve retention, and deliver a better digital experience for members
- Need strong support from a team that understands how membership organizations actually work
If you are currently on iMIS and feeling constrained by complexity, cost, or the need for consultant support to make changes, we'd welcome a conversation.
