For teams running Sage 100 or Sage 300
The last year you pay for ERP software.
iDempiere is free, open source ERP — always has been, always will be. For 20+ years it has run real mid-market businesses in distribution, service, and light manufacturing. Off-the-shelf, with the freedom and flexibility to make it yours. Our goal: a go-live costing about one year of Sage licensing.
Why Leave Sage
Your Sage bill goes up. Your options go down.
Spend where it matters most: your people and your operations. Freedom and flexibility matter — this is where you invest. If your support does not get better, but the invoice keeps getting bigger — exit! The only hard part is the transition, and that is exactly how we help.

How It Works
Four Steps to Your Last Sage Renewal
Audit Your Sage System
Map what you own: modules, customizations, integrations, data quality. Know exactly what you're moving.
Learn & Configure
Work through the community's guided training. Configure iDempiere against your audit, with checklists reviewed by experts.
Migrate & Go Live
Follow the deploy playbooks for data migration and go-live. Our goal: about one year of Sage licensing, total — and we go to heroic lengths to hit it.
Run & Scale
$0 licensing, forever. Stay in the community for support, upgrades, and a place to ask when you grow.
The Economics
Joining the ERP Commons community.
Only the migration team and your critical users need to join the ERP Commons community — the people performing the migration, not your whole user base.
Membership is $50 per user per month. The above example assumes 10 users. Your entire team's year of membership costs about one-tenth of a yearly Sage invoice. Sage pricing varies — check your renewal.

About
People who have lived it.
This is a people-powered, AI-augmented community. ERP transitions fail on the hard-won lessons — the "we tried that, and here's what broke" — not on software features. Members get the people who have done this before, the artifacts they built along the way, and AI that makes a small team move like a big integrator.
The community lives on GitHub at erpcommons-sage: private repos, shared tickets, resources, and a calendar for booking expert time. Membership is $50 per GitHub user per month via Stripe checkout.
