AMS Pie ChartSo you run an association, and it's quite complex. But you know that.

You might be stuck using Excel. Or trapped in a proprietary solution that doesn't even let you download your own database or view the source code. We believe association management software should serve the membership, the board of directors and the executive director of the association equally.

Associations are complex. Just the opening paragraph from Wikipedia makes your head spin with the implied complexity of any AMS system.



If you are reading this, it's because YOU care about YOUR association's mission and vision. And about the people who are members.

AMS, MMS, CRM for non-profits - we call them by different names. Sometimes it's membership management at a simpler level. Yet every association that sustains eventually hits a level of complexity that goes beyond basic membership management.

The requirements grow in complexity and the members themselves have to participate in their own data management. (hint: that's why Tendenci is Open Source and even hosted we do NOT charge based on named users. Just on the power of the server you need!)

Tendenci is the strongest and most secure web-based software platform for NPO’s globally. We are offering you a software that is completely open-source, fully customizable and highly integrated, a software that offers high security and a platform that makes you rethink your membership management strategy.

Tendenci – The Open Source AMS continues to grow globally, we believe because it is a community much more than anything else. All of the code is on Github, documentation on readthedocs, and the translations are crowd-sourced on Transifex. Self-host or host with us, your choice, your data, your association.

Here in the US Alexis du Tocqueville wrote about organizations in our society:

Americans of all ages, all stations of life, and all types of disposition are forever forming associations… In democratic countries knowledge of how to combine is the mother of all other forms of knowledge; on its progress depends that of all the others.


You have lots of options in choosing an MMS or AMS. From Wild Apricot to Member Clicks or Personify - all viable options. But if you need to scale to hundreds of thousands of members, have recurring memberships, organizational memberships and need the full features of a seasoned large scale enterprise AMS, it's possible you might hit some limits with the new kids on the block

The proprietary vendors are companies first and communities second. Tendenci is a community first, and yes there is a small company behind it. It's just grown far bigger than we were expecting. And given it was started in 2001, when you switch from a proprietary solution it's an upgrade!

Feel free to take the demo site for a spin! Every site looks completely unique using Bootstrap themes. No long term contracts. Access to all of your data at any time. Full access to the source code. Everything under YOUR domain name.

If you are into the whole Freedom thing, then hey, Tendenci is The Open Source AMS and we'd love to see you around on GitHub or contact us if you'd like our help setting your site up.

Consider your decision picking an AMS this way

With Tendenci, you can self-host, host with us, leave whenever you want. If Tendenci isn't the right AMS to manage your memberships, you are free of constraints! Why lock into a 2-year contract first when you are stuck, whereas if you go with open source, you won't have to ever have a conversation with the board of directors saying:

"oops, the proprietary solution isn't scaling up and is limiting, but we're stuck with it for another two years."

We are people who build software and support the Association Management community out of a passion to serve you. Join us?

Lastly, yes, Tendenci is a very large project with robust functionality. But it's still a great free or low-cost solution as an AMS for small associations too. You can easily disable the modules you don't need and keep it simple. The functionality will be there as your small association AMS needs to expand in the future!  Freedom is pretty cool, huh? Payless (or self-host!) and get greater functionality. Rock on!
