Epicor Prophet 21 Specialists150+ P21 API Endpoints

Sales Order & Order Entry Automation for Epicor Prophet 21

Stop hand-keying customer POs into P21. ESS Fusion AI reads any customer purchase order with AI vision — no OCR templates — validates the ship-to and items against your live P21 data, and creates the sales order directly in Prophet 21.

From a customer PO to a created P21 sales order in minutes, not hours — no templates, no re-keying.

Order Entry Is Where the Time Goes

Order-entry and CSR teams spend their day turning emailed POs into P21 orders by hand. Here's what that costs you.

Hand-keying every PO

CSRs re-type customer purchase orders from dozens of different layouts, one field at a time, all day long.

10–20 minutes per order

Each document eats CSR time that should be spent on customers, not data entry.

Template OCR breaks

Zonal OCR works until a customer changes their PO layout — then it silently fails or mis-reads.

Errors flow downstream

A wrong item or ship-to typed at order entry propagates into picking, fulfillment and shipping.

Peak-season backlogs

Order volume spikes faster than you can staff, and POs pile up in the inbox waiting to be entered.

No visibility

Orders sit unconfirmed in email with no clear queue, status or audit trail.

From Customer PO to P21 Sales Order in Four Steps

No templates. No re-keying. No Epicor API module required on-prem.

1

Ingest the PO

Customer purchase orders arrive via email, Google Drive, Azure Blob or upload — fully configurable.

2

Read any layout

AI vision reads every field across any customer PO layout — no templates, no zones.

3

Validate against P21

Customer, ship-to and items resolved against your live P21 data; returning customers auto-map, new ones get suggestions.

4

Create the order

The sales order is created directly in Prophet 21 via our API. Exceptions are reviewed in a chat-style interface.

Returning Customers

Field mappings are already learned, so their POs are fully automated — the order is created in P21 with no setup and no human touch when confidence is high.

New Customers

The AI agentic system suggests field mappings from historical patterns across similar layouts. A reviewer confirms once in a chat-style interface — and every order after that gets faster.

The P21 Difference

A 150+ Endpoint Domain API That Creates the Order in P21

Most order-entry tools stop at extraction and hand you a file. We go all the way into the ERP. ESS has built a simplified domain API on top of Epicor — 150+ endpoints covering orders, customers, ship-to, inventory and more — so ESS Fusion AI doesn't just read a customer PO, it creates the sales order in P21.

  • Native on-premises API layer — no Epicor API module required
  • Validates customer, ship-to and items against live P21 data
  • Bi-directional, real-time sync with P21
  • Works on Epicor Cloud and legacy on-prem installs alike

Epicor P21 Sales Order Automation — FAQ

How does sales order automation work with Epicor Prophet 21?

ESS Fusion AI ingests customer purchase orders from email, shared drives or cloud storage, uses an AI vision agentic system to read every field with no templates, validates the customer, ship-to location and items against your live P21 data, then creates the sales order directly in Prophet 21 through our domain API layer. High-confidence orders flow straight through; uncertain ones go to a reviewer in a chat-style interface.

Do we need the Epicor API module to automate order entry on Prophet 21?

No. ESS provides a native on-premises API layer with 150+ endpoints purpose-built for P21, so order automation works on both Epicor Cloud and legacy on-prem installs that do not have the Epicor API module licensed.

How are new customers handled differently from returning customers?

Returning customers get fully automated field mappings — the system already knows how that customer's PO layout maps to your P21 fields, so their orders flow through with no setup. For new customers, the AI agentic system offers intelligent mapping suggestions drawn from historical patterns across similar layouts, so a reviewer confirms rather than configures from scratch. Every confirmation makes the next order from that customer faster.

Is this different from order-entry OCR tools like DocStar and Ephesoft?

Yes. Traditional OCR capture tools — including DocStar and Ephesoft — rely on per-customer zonal templates that break when a layout changes and typically hand back an export file you still have to key into P21. ESS Fusion AI is template-free AI vision, and it writes the validated sales order straight into P21 instead of producing a file to re-key.

Where does our order data go?

The platform runs in your own Azure or AWS tenant with enterprise encryption, and your customer POs are never used to train public AI models. A fully air-gapped, self-hosted option is available for the strictest requirements.

How fast can we go live on P21 sales order automation?

Because the P21 order endpoints and order-entry pipeline already exist, most clients run a pilot on their highest-volume customers within days and expand from there.
