On-prem Epicor? Choose your path before Epicor chooses it.
Epicor has announced that active support for on-premises Prophet 21 ends on 30 June 2029 and for on-premises Kinetic on 31 December 2029, with the last on-premises releases in 2028. QServices helps Epicor users weigh the cloud, sustaining support or a move, rebuilds the integrations that break on the way, and adds AI agents through Epicor's own APIs.

Prophet 21on-premisesEpicor cloudor another pathProphet 21 reaches sustaining support six months before Kinetic.
Sustaining support from 1 Jul 2029: limited phone help and the knowledge base, no security updates or new-issue investigation.
Sustaining support from 1 Jan 2030, on the same terms.
The earliest of the three.
As reported by CIO, Constellation Research and ERP Today, which agree. Epicor counts customers on unaffiliated hosting as on-premises.
Third-party support barely exists for Epicor: neither Rimini Street nor Spinnaker Support lists it, as of October 2026. So the real choice is between these four.
Your customizations are mostly BPMs, BAQs and Epicor Functions.
Epicor, its data model and every new AI feature, which now ship in the cloud only.
No direct SQL, custom assemblies or SQL-based reports, and an upgrade roughly every six months. Users report 6 to 10 month moves.
A stable site buying two or three years to plan properly.
The system as it is today.
No security updates and no investigation of new issues. Integrations frozen on the last API.
You need control over where the system runs.
Options, for now.
Epicor says it is evaluating hybrid and customer-controlled deployment, with no published details or dates.
Epicor's cloud doesn't fit, or trust has gone.
Your data, through a full conversion.
A full implementation, with the AR cutover planned properly.
The same few things break on almost every project. Finding them before the move is most of the work.
| Item | Why it breaks | The fix |
|---|---|---|
| BPMs with custom code | Converting Epicor 10 to Kinetic renames table references from tt to ds, including variables that merely start with tt, and the code fails silently | Review and test every custom BPM before go-live |
| Integrations on direct SQL | Not allowed in Epicor's cloud | Rebuild on REST API v2 and Epicor Functions |
| Integrations on REST v1 | Deprecated since 2022.2 | Move to v2, which needs an API key plus a user login |
| Classic screens and dashboards | They don't convert to Kinetic's interface | Rebuild in the Kinetic designer |
| SQL-based reports | No SQL access in the public cloud | Rebuild on BAQs or move them to Power BI |
| Large data pulls | REST v2 returns 100 rows by default, and cloud customers can't raise it | Page through results or use BAQ exports |
From epiusers.help threads, 2W Tech (partner) and API documentation reviews, labelled as such in our sources.
| Epicor Kinetic | Epicor Prophet 21 | |
|---|---|---|
| Built for | Discrete and mixed-mode manufacturers | Wholesale distributors |
| Strengths | Jobs, MRP and the shop floor | Counter sales, pricing, rebates, purchasing, warehouse |
| Last on-premises release | 2028.1, about January 2028 | 2028.1, about May 2028 |
| Main API | REST v2 (OData v4) with API keys and scopes, BAQs, Epicor Functions | Self-hosted middleware: REST, Entity, Interactive and OData APIs, no OAuth |
| Change notices | None built in; BPMs or Functions can post out | None documented; poll or track changes |
Our comparison, built from the API reviews and Epicor's positioning. Both need the integration work above before a cloud move.
Epicor is putting its AI into the cloud. On-premises customers, and anyone with work Epicor's agents don't cover, need another route.
Epicor's AI agents, live in the UK and Europe since 23 June 2026, with people overseeing their work. Cloud only.
A July 2026 partnership bringing AI order and invoice capture to Prophet 21 distributors.
Cash application, collections and order entry agents working through REST v2, on-premises or cloud.
AI agentsFixed price per phase. We don't sell Epicor licences, so the recommendation is about your business.
Every customization, integration, report and dashboard listed, with the work each path needs.
Your team chooses cloud, sustaining support or a move, with the costs side by side.
Integrations on REST v2 and Functions, BPMs reviewed, dashboards and reports rebuilt.
Cash application and order entry agents that keep working whichever path you pick.

Epicor itself, on sustaining support: limited phone help, the knowledge base and the latest release, but no security updates and no investigation of new issues. It starts on 1 July 2029 for Prophet 21 and 1 January 2030 for Kinetic. Independent third-party support for Epicor is very limited.
Kinetic is the current generation of what was Epicor 10, with a new browser interface. Upgrading converts the system, but custom BPM code, classic screens, dashboards and old integrations usually need work.
Standard BPMs carry over. Custom code inside them can break, because the conversion renames tt table references to ds, including variables that only happen to start with tt. Test every custom BPM before go-live.
Epicor Prism, its agent platform, went live in the UK and Europe in June 2026, and new AI features ship in Epicor's cloud only. For on-premises systems or work Epicor doesn't cover, custom agents can work through REST API v2.
Epicor doesn't publish upgrade or cloud migration pricing. The cost depends on custom BPMs, SQL-based integrations and reports, dashboards and data volume. We price each phase after a two-week assessment.
Ask how they'll find custom BPM code that breaks on conversion, how they'll rebuild SQL-based integrations for the cloud, what they'll test before each cloud update, and whether they're paid to recommend a particular path.
The last on-premises release is in 2028. Find out what your path needs now.
