The short version

Dynamics GP cannot be bought any more. It is an on-premises ERP system for small and midsize businesses, sold as Great Plains for decades and as a Microsoft product since 2001, and it still runs a very large number of US back offices. What remains is a retirement schedule. The final security patch is dated April 30, 2031.

Where Dynamics GP comes from

Great Plains Software started in Fargo, North Dakota, and its Dynamics line became a leading mid-market accounting product of the client-server era. Microsoft acquired the company in 2001 and later renamed the software Microsoft Dynamics GP. The retirement plan confirmed in 2024 comes down to four dates: new perpetual license sales ended April 1, 2025; new subscription sales ended April 1, 2026; enhancements, service packs, technical support, and tax and regulatory updates end December 31, 2029 (moved back slightly from the originally announced September 2029); security updates stop April 30, 2031.

What it covers

Core financials first: general ledger, payables, receivables, fixed assets, bank reconciliation. Distribution adds inventory, sales order processing, and purchase order processing, and the suite reaches into US payroll and human resources, project accounting, and basic manufacturing. The decisive part of a typical footprint sits outside that list. A large ISV ecosystem pushed GP into verticals such as field service and nonprofit fund accounting, and many installations lean heavily on those third-party modules.

Typical customers

Sales ran almost entirely through a value-added reseller channel in the United States and Canada: distributors, professional services firms, nonprofits, local government, light manufacturers. The classic profile is a company that had outgrown entry-level accounting software but had no use for a full enterprise suite. Since nothing can be sold today, the audience for this profile is the installed base deciding how and when to move.

Licensing, hosting, cost

GP runs on customer-managed Windows Server and SQL Server, and much of the base has already moved its instances to partner-hosted or Azure IaaS environments. No price list exists, because there is no product to price. Existing customers still pay annual enhancement or subscription fees, partner support agreements, and infrastructure, and those numbers are increasingly measured against a replacement budget; our ERP cost guide helps frame that comparison.

Our take

Treat this listing as a migration source, not a shortlist entry. The dates set the strategy: functional and tax updates stop at the end of 2029, which is the practical hard stop for anyone running GP payroll or year-end tax reporting, and it makes the 2031 security cutoff a formality. Microsoft steers the base toward Dynamics 365 Business Central with migration tooling and partner promotions, while Acumatica, Oracle NetSuite, and Sage Intacct court the same customers, often successfully when a company wants to reassess its partner at the same time. Nobody selecting ERP for the first time should look at GP at all. Companies whose footprint depends on ISV modules should start requirements and data migration planning now, because qualified partner capacity is expected to tighten as the deadlines approach.

Frequently asked questions

When does support for Microsoft Dynamics GP actually end?

There is no single cutoff, but a staged timeline. Product enhancements, tax and regulatory updates, service packs, and technical support all end on December 31, 2029, a date Microsoft moved back slightly from the originally announced September 2029. After that, security patches are issued only as needed, and they stop on April 30, 2031, which is the definitive end of the product.

Can my company still buy Dynamics GP licenses or add users?

New perpetual license sales ended April 1, 2025, and new subscription sales ended April 1, 2026, so no company can adopt the product from scratch any more. Existing customers keep the rights they own and may run the system through the remaining support timeline. Whether extra modules or user counts can still be added depends on the license type, so confirm it with the Microsoft partner managing the account.

What are the realistic migration paths away from Dynamics GP?

Microsoft positions Dynamics 365 Business Central as the default successor and backs that route with migration tooling, data conversion assistance, and partner incentives. Acumatica, Oracle NetSuite, and Sage Intacct also target the GP installed base and land on shortlists regularly, particularly where the customer wants to change partners as well.

What happens to our third-party ISV modules during a migration?

They are usually the hard part. Many GP installations depend heavily on ISV extensions for field service, nonprofit fund accounting, and similar verticals, and those rarely carry over one to one. Each add-on has to be mapped to an equivalent on the target platform or rebuilt, which is why the ISV inventory, not the general ledger, tends to drive both the effort estimate and the choice of successor system.

Is it risky to keep running Dynamics GP until the final deadline?

Technically possible, operationally uncomfortable. After December 31, 2029 there are no US payroll tax updates and no regulatory releases, which makes that date the practical hard stop for anyone using GP payroll or year-end tax reporting. Insurance, audit, and compliance requirements increasingly penalize unsupported software, so most advisors want the migration finished before the enhancement deadline rather than racing the 2031 security cutoff.

What does Dynamics GP cost today?

No published price list exists, since Microsoft no longer sells the product. Existing users pay annual enhancement or subscription fees, partner support agreements, and the Windows and SQL Server infrastructure underneath. A fair comparison against a replacement project has to include migration, retraining, and ISV replacement costs rather than license fees alone.
