Why Associations Are Switching

iMIS was built for a different era of
association management

It was designed when deep customization was the goal. Today, that same customization is precisely what’s keeping associations stuck — on old versions, with painful upgrade paths and growing technical debt. re:Members offers a modern alternative without losing the flexibility your association depends on.

Architecture

Cloud-native by design vs. retrofitted to the cloud

The single biggest difference between re:Members and iMIS isn’t a feature — it’s how the systems were built. Architecture decides everything that comes after: upgrades, integrations, performance, and your team’s daily experience.

re:Members AMS

Built cloud-native
from day one

  • Built from the ground up on Microsoft Azure
  • All clients always on the latest version
  • Automatic updates 3x per year — no manual upgrades
  • Direct access to Snowflake data warehouse
  • Native Microsoft Power Platform integration
  • Configuration through checkboxes, drop-downs, and no-code workflows
iMIS

A legacy system
retrofitted for cloud

  • Originally server-based, later adapted to cloud (EMS)
  • Clients often stuck on old versions
  • Upgrade paths described by users as "painful"
  • Limited SQL access in the cloud version
  • Complex IQA reporting tool requires technical expertise
  • Most changes require vendor support and additional fees
Detailed Feature Comparison

Where re:Members wins — and where
the differences matter

Six categories, scored honestly. We give iMIS credit where it’s earned — but the gaps tell a clear story.

Configurability

re:Members

Configure workflows, fields, and business rules through checkboxes and drop-downs. Staff make changes without coding or vendor dependency.

iMIS

Requires extensive customization and development resources. Most changes require vendor support and additional fees.

Pricing

re:Members

Site license covers unlimited users. All modules included. Predictable annual subscription with no surprise bills.

iMIS

Per-user licensing, module-based pricing, expensive customizations, and ongoing professional services fees that compound over time.

Implementation

re:Members

Outcome-based implementation done in-house. Typical timeline 4–6 months. Clear scope, clear costs, no third parties.

iMIS

Often requires third-party integrators. Lengthy implementations with unpredictable costs that frequently exceed initial estimates.

Data & Reporting

re:Members

Snowflake data warehouse, native Power BI integration, and an intuitive query builder that lets you ask questions in plain English.

iMIS

Restricted SQL access in cloud version. Complex IQA tool requires technical expertise. Reports often need outside help to build.

Upgrade Path

re:Members

Automatic updates 3x per year. No risk of falling off the upgrade path. Configuration carries forward — not the customizations that break.

iMIS

Heavy customizations make upgrades expensive and risky. Clients describe systems “collapsing under their own weight” after years of use.

Ease of Use

re:Members

Intuitive interface with minimal training. AI-powered help and conversational search. Staff can self-configure on day one.

iMIS

Complex interface with steep learning curve. Frequent login and session-timeout issues lead to low staff adoption.

Pricing Models

Predictable site license vs.
unpredictable module fees

iMIS pricing rewards complexity — more users, more modules, more customization, more cost. re:Members rewards growth with a single, all-inclusive subscription.

re:Members AMS

All-Inclusive Site License

One predictable annual fee. Every module. Every user. Every staff member.

  • Unlimited staff and member access included
  • All modules included — no add-on fees
  • Fixed annual subscription, no surprises as you grow
  • Fixed-fee implementation with clear timeline and scope
  • Snowflake, Power BI, and Power Automate included
  • Automatic updates 3x per year at no extra cost
iMIS

Module-Based Licensing

Variable costs that grow with your organization — often unpredictably.

  • Per-user licensing that scales as you hire
  • Pay separately for reporting, certification, advertising, exposition modules
  • Costs increase as your organization grows
  • Time-and-materials implementation with unpredictable totals
  • Ongoing professional services fees for every change
  • Upgrade costs in addition to base license fees

Need something even more customizable?

For larger associations with advanced development capabilities, re:Members AMS Platform delivers a fully customizable solution built on Salesforce — combining enterprise-grade scalability with our membership expertise.

Real Migrations, Real Results

Associations that made the switch from iMIS

Three organizations that knew iMIS inside and out — and decided the future was somewhere else.

CompTIA

Computing Technology Industry Association

“We’re kind of a victim of our own doing… and a victim of our own success in terms of the growth we’ve experienced that’s really starting to expose the real liabilities that we’ve built for ourselves.”

Situation

Stuck on a very old version of iMIS with massive customizations. Had to wrap “massive security around it to isolate it because the upgrade path was so painful.” Couldn’t trust the data in Power BI.

ACA

American Counseling Association

“If we’re going to have to redo everything anyway… we’re going to look at everything, we’re going to consider all of our options.”

Situation

On iMIS for 10+ years and planning an EMS upgrade. Realized the cloud migration would cost as much as switching to a new system entirely — and they’d lose SQL access in the process.

AIAG

Automotive Industry Action Group

“ASI is a one-size-fits-all. You have to use it the way it is. If it doesn’t work for you, well, too bad… We need to move beyond that.”

Situation

On iMIS for 18+ years with heavy customization. Could only link parent-to-child relationships (not multi-level), with duplicate record issues and limited reporting flexibility.

The Concerns You're Already Thinking About

Common questions from
associations evaluating a switch

If you’ve been on iMIS for 10, 15, or 20 years, you have legitimate concerns. Here’s how we address the ones we hear most.

"We've been on iMIS for 15–20 years. It's too embedded to switch."

Our Response

We hear that frequently, and most of our clients were in the exact same position — on iMIS for 10–20 years before making the switch. The level of embeddedness is exactly why we invest heavily in our implementation process. We’ve completed 20+ iMIS conversions and have it down to a science. We understand the complexity and have proven processes to migrate your data, configurations, and business rules. The real question isn’t whether you can switch — it’s whether staying on iMIS is sustainable for your future needs.

"We're already planning to upgrade to iMIS EMS — the cloud version."

Our Response

That’s a smart move to consider cloud, but we’d encourage you to treat the EMS upgrade like you would any new system evaluation. You’re going to lose some functionality, face significant costs, and still need to change business processes anyway. If you’re going to invest that time and money regardless, it makes sense to look at what else is available. Many organizations find that for the same investment, they can move to a more modern, more flexible platform — without the legacy baggage.

"iMIS can do anything if we customize it enough."

Our Response

That’s actually one of the challenges we hear most often. Yes, iMIS can be customized to do almost anything — but at what cost? We regularly talk to organizations spending hundreds of thousands on customizations, then getting stuck because they can’t upgrade without breaking everything. Our approach is different: we give you the configurability to meet your unique needs without custom code, so you never fall off the upgrade path and can adapt as your needs change. And if you do need the full power of customization, our AMS Platform built on Salesforce is purpose-built for that.

"We don't have the resources for a major system change right now."

Our Response

We understand, and that’s exactly why our implementation model is different. We do fixed-fee implementations with clear timelines and outcomes — you’re not managing multiple vendors or dealing with time-and-materials billing. Plus, think about the resources you’re already spending today: staff time working around system limitations, vendor fees for every change, IT resources maintaining customizations. Many clients find they actually free up resources after switching, because the system is so much easier to use and maintain.
