Microsoft ends GP support on December 31, 2029 — and if you're on GP 2018 or older, your extended support ends January 2028 and you've already lost tax and year-end updates. We migrate Great Plains shops to Dynamics 365 Business Central: assessment, data, go-live, and the support after. Remote, US-wide.
These are Microsoft's published dates. The pattern is simple: every exit ramp is behind you except the last ones.
GP 2018 moved to extended support — which does not include tax or year-end updates. If you're closing years on GP 2018 today, you're already doing it unsupported.
Microsoft stopped selling GP perpetual licenses to new customers.
Subscription sales to new customers ended. GP is now closed to new buyers entirely; existing customers with active plans can still add users and modules.
If you're on GP 2018 or older: after this date, no support of any kind. This is the deadline that matters for most small GP shops still running older versions.
Product enhancements, service packs, regulatory and tax updates, and technical support end for every GP version — including the current 18.x releases.
After this date, GP receives nothing. An internet-connected ERP with no security patches is a standing invitation — and cyber insurers know it.

Your GP install will boot fine on January 1, 2030. What changes is everything around it — quietly, then all at once:
And the practical one: migrations get more expensive under deadline pressure. The companies that move on their own schedule get the good timelines and the good pricing.

Chart of accounts (keep or restructure), master records, open transactions, historical-data decision, and ISV replacements in the Business Central ecosystem.
Data migration with parallel validation, user training on real workflows, and a go-live timed to your month-end or fiscal year — typical small-business runs: 8–16 weeks.
Ongoing Business Central support, licensing, and administration — plus the managed IT and security under it. GP's read-only archive stays available for history.

Microsoft ends product support, enhancements, and regulatory (tax) updates for Dynamics GP on December 31, 2029, with security patches continuing only until April 30, 2031. Older fixed-lifecycle versions end sooner — GP 2018 and 2018 R2 extended support ends January 11, 2028, and extended support already excludes tax and year-end updates.
No. Microsoft ended new perpetual license sales on April 1, 2025 and new subscription sales on April 1, 2026. Existing customers with active plans can still add users and modules, but no new customers can buy GP.
No one forces you, but staying means running an unsupported ERP: no tax updates, eventually no security patches, shrinking consultant availability, and rising cyber-insurance friction. Business Central is Microsoft's designated successor with migration tooling and promotional licensing for GP customers — but the right answer depends on your modules, ISVs, and plans, which is what an assessment determines.
Typically master records (customers, vendors, items, chart of accounts), open transactions, and GL history move to Business Central, while full historical detail is preserved in a read-only archive or reporting database. Bringing every historical transaction into BC is possible but rarely worth the cost — we help you make that call deliberately.
For small businesses on mostly core GP modules, typical migrations run roughly 8–16 weeks from kickoff to go-live, often timed to a month-end or fiscal-year boundary. Heavy customizations, many ISV add-ons, or complex integrations extend that — the readiness check above gives you an early read.
It depends on modules, ISVs, data decisions, and user count — which is why we quote fixed-price after a free assessment rather than quoting blind. Small-business GP migrations are far more affordable than mid-market ERP projects, and Microsoft has offered promotional Business Central licensing for migrating GP customers.
