You have lots of options when choosing 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 full features of seasoned large scale enterprise AMS, itโ€™s possible you might hit some limits with new kids on the block. Proprietary vendors are companies first and communities second. Tendenci is community first, and yes, there is a small company behind it. Itโ€™s just grown far bigger than we were expecting, and given it started in 2001, when you switch from 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 source code. Everything under YOUR domain name. With Tendenci, you can self-host, host with us, leave whenever you want. If Tendenci isnโ€™t the right AMS to manage YOUR memberships, you are free of constraints!

Stacksync features and specs

  • Two-Way Sync
    Keep your systems perfectly aligned with Stacksyncโ€™s reliable two-way data synchronization. Changes made in one platform automatically update across all connected systems in real time, eliminating data silos, reducing errors, and ensuring your teams always work with the latest information.
  • Workflow Automation
    Stop building brittle API scripts. With Stacksync, you can trigger complex automated workflows using simple SQL commands. Instantly initiate email sequences, update CRM statuses, or fire webhooks whenever a specific record changes in your database, giving you total control without the maintenance headache.
  • EDI
    Transform legacy EDI complexity into simple database interactions. Stacksync automatically parses incoming EDI documents directly into your database tables and converts outgoing data back into compliant EDI formats. Manage your supply chain with the ease of SQL, not ancient file parsers.
  • Databases
    Interact with your CRM, ERP, and payment tools as if they were just another table in your database. Stacksync mirrors your SaaS data into Postgres or Snowflake in real-time, allowing you to read and write data using standard SQL. Say goodbye to rate limits and complex API documentation.

  • The Seven Engineering Problems That Make Real-Time Enterprise Sync Almost Impossible
    Three years and one Y Combinator batch later, Stacksync syncs millions of records across 200+ enterprise systems with sub-second latency. I want to explain why this problem is as hard as it is, because most engineering teams underestimate it until they're six months into a failing project. - Source: dev.to / 4 months ago
