A 150+ Endpoint Domain API That Takes the Complexity Out of P21
Most document 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 partial invoices, inventory returns, orders and more — so DocumentAI doesn't just read a document, it completes the transaction in P21.
- Native on-premises API layer — no Epicor API module required
- Pre-built mappings for orders, POA, invoices, inventory, returns, packing slips
- Bi-directional, real-time sync with live P21 data
- Works on Epicor Cloud and legacy on-prem installs alike

AI vision, not zonal OCR

Epicor P21 Document Processing — FAQ
How does AI document processing work with Epicor Prophet 21?
ESS DocumentAI ingests documents from email, shared drives or cloud storage, uses an AI vision agentic system to extract every field with no templates, validates customers, ship-to locations and items against your live P21 data, then creates the order, invoice or receipt directly in Prophet 21 through our domain API layer. High-confidence documents flow straight through; uncertain ones go to a reviewer.
Do we need the Epicor API module to use this on Prophet 21?
No. ESS provides a native on-premises API layer with 150+ endpoints purpose-built for P21, so the platform works on both Epicor Cloud and legacy on-prem installs that do not have the Epicor API module licensed.
Which P21 documents are supported out of the box?
We ship pre-built mapping templates and pipelines for purchase orders, sales orders, invoices, purchase order acknowledgements (POA), inventory and returns, and packing slips. Additional document types are added through configuration, not custom code.
Is this different from DocStar and other OCR capture tools for Epicor?
Yes. Traditional OCR capture tools — including DocStar and Ephesoft — rely on per-vendor zonal templates that break when layouts change and typically hand back an export file you still have to import. ESS DocumentAI is template-free AI vision, and it writes validated records straight into P21 instead of producing a file to re-key.
How fast can we go live on P21?
Because the P21 endpoints and document pipelines already exist, most clients run a pilot on their highest-volume document type within days and expand from there.
Where does our data go?
The platform runs in your own Azure or AWS tenant with enterprise encryption, and your documents are never used to train public AI models. A fully air-gapped, self-hosted option is available for the strictest requirements.
