What Is Epicor Prophet 21?
Epicor Prophet 21 — commonly called P21 — is a leading distribution ERP system built for wholesalers and distributors. It runs the whole business in one platform: inventory and warehouse management, purchasing, sales orders and quotes, pricing, financials and reporting. Prophet 21 is purpose-built for the order-to-cash and procure-to-pay cycles that distribution companies live in every day.
The value of P21, though, comes from how it's implemented, supported and extended.
