Microsoft Dynamics GP is ending
Leave Dynamics GP on your terms. Land somewhere no vendor can end.
Microsoft has set the clock on Great Plains. This is the plan for getting off it cleanly: what the dates really mean, what each destination honestly costs, and where we think most GP shops should land. Our default recommendation is Odoo, the open source ERP you can own and host yourself, and we make the case for every other path too, including when they beat it. Written by the engineers who do the migrations, not a reseller.

What the Dynamics GP end of life actually means
Four dates, one that matters most. If you run payroll or file taxes from GP, December 31, 2029 is your real deadline.
You can no longer buy GP outright.
No net-new GP instances. Existing shops can still add users.
The practical deadline: no more regulatory or payroll tax updates.
GP is frozen. No new users, even on perpetual licenses.
By the numbers
The scale of what is ending
Dynamics GP is not a niche product winding down quietly. It is a mid-market standard on a fixed clock, and the systems replacing it are large, mature, and mostly in the cloud.

Where we stand
We tell you the truth about every path
Most GP-migration advice comes from a reseller who only wins if you buy their product. We are engineers, and every destination on this site gets the honest case for and against. For most GP shops that truth points to Odoo: open source, so nobody can sunset it out from under you again. And because we implement and extend Odoo rather than resell it, we build the system with you instead of billing you a license.
Where should you migrate?
For most GP shops our recommendation is Odoo, and its page explains exactly why. But no default fits everyone, so here is the honest case for every path, including when Business Central, QuickBooks, or a custom system beats it.
Migrating from Dynamics GP to Odoo
Our default pick for most GP shops
Odoo is the open source ERP that cannot be sunset out from under you. Why it is our default recommendation for most GP shops, and the honest tradeoffs.
