Epicor Prophet 21 Consulting & Implementation
From first demo to go-live to long-term support — one client-focused team, no handoffs. ESS implements, migrates, customizes and integrates Prophet 21 for wholesale distributors, with deep knowledge of P21's business rules and a native API layer that needs no Epicor API module.
One team owns the whole Prophet 21 lifecycle — assessment, migration, customization, integration and support — so nothing falls through a handoff.
End-to-End, Not Just Setup
A client-focused implementation that reduces risk at every step and carries you well past go-live.
Assess & Plan
We map your distribution workflows, data and integrations, and define a Prophet 21 configuration that fits how you actually run.
Migrate & Build
Legacy data is mapped and migrated incrementally; customizations, integrations and reports are built on P21's supported framework.
Validate & Train
Parallel validation, user training and dry-run cutovers so the business is ready and the data is trusted before go-live.
Go-Live & Support
We carry you through cutover and stay on for ongoing support, enhancement and optimization — no handoff to a stranger.

Epicor Prophet 21 Consulting — FAQ
What does ESS do as an Epicor Prophet 21 consulting partner?
ESS provides end-to-end Prophet 21 services: requirements and fit analysis, full implementation, legacy data migration, customization and business-rule automation, system integration, reporting, and ongoing support. With 15+ senior consultants and 25+ years across wholesale distribution, we own the project from first demo to go-live and beyond.
Do you handle new Prophet 21 implementations and re-implementations?
Both. We implement Prophet 21 for distributors moving off legacy systems, and we re-implement or stabilize P21 for companies whose original rollout never reached its potential — cleaning up data, configuration and workflows so the system finally works the way the business runs.
Which legacy systems can you migrate from?
We routinely migrate distributors to Prophet 21 from A+, Baan/Infor, Macola, Excel, Microsoft Access and flat files — mapping both master and transactional data, plus pricing pages, contracts and rebates. See our dedicated Prophet 21 upgrade & migration page for the full approach.
What makes ESS different from other Epicor partners?
Depth and ownership. Our team knows P21's business rules inside-out, builds on its supported extension points, and backs everything with a native on-premises API layer — so we can customize and integrate deeply without the Epicor API module. One client-focused team carries the whole lifecycle, with no handoffs.
How long does a Prophet 21 implementation take?
It depends on scope and data complexity, but our proprietary migration tooling lets us start moving data incrementally weeks before go-live and validate it in parallel — compressing the timeline and de-risking the cutover compared with a single big-bang migration.
