How to add document OCR to Epicor Vantage and Epicor 9
Short answer
Capture scanned and digital documents with layout-aware OCR and a model, match the fields to Epicor vendors, POs and receipts, and post to AP or receiving through the business object services. Low-confidence fields go to a person, and the image is stored against the transaction.
Epicor Vantage and Epicor 9 sites still receive paper and PDF documents all day: vendor invoices, packing slips, certs of conformance, material test reports, and customer drawings. Clerks key them into AP Invoice Entry and Receipt Entry, and file the paper.
OCR for this platform is less about reading text, which is mostly solved, and more about matching what was read to your vendor, PO line and part. A correct total on the wrong PO is still wrong.
A good design treats OCR output as a proposal. The system shows the image next to the proposed transaction, highlights uncertain fields, and learns from corrections.
What teams use it for
Vendor invoice capture to AP
Read invoice number, date, totals and lines, match to the PO and receipt, and stage an AP invoice with variance flags for review.
Packing slip to receipt
Extract packing slip number, part and quantity, and prefill a receipt against the open PO release.
Certificate of conformance and mill test reports
Read heat or lot numbers and attach the certificate to the received lot for traceability.
Customer drawing intake
Extract title block data such as part number, revision and material from drawings and link them to the part revision.
Delivery signatures and proof of delivery
Read signed delivery documents and attach them to the shipment record.
Epicor Vantage / Epicor 9 integration surface
- AP invoice and receiving business object web services for staging transactions with standard validation. Names vary by release.
- PO, PO release and receipt data accessed through Business Activity Queries for three-way matching.
- Lot and part lot tracking features for attaching certificates to received lots, where lot tracking is enabled.
- Attachment capability on parts, POs, receipts and shipments, depending on version and configuration, or an external document store with a reference field.
- Read-only database access (Progress OpenEdge ODBC, or SQL Server on some installs) for lookups when queries are not enough.
How it works
- 1
Set up capture channels
Accept scans from a network folder, a multifunction printer, or an email mailbox. Assign each channel a default document type where possible.
- 2
Run layout-aware OCR
Use an engine that preserves tables and positions, and deskew and clean scans first. Plain text OCR loses line item structure.
- 3
Extract and score
A model maps text to fields and gives each a confidence score. Totals are cross-checked against line sums.
- 4
Match to Epicor
Resolve vendor from name, tax ID or remit-to, then the PO and receipt. Flag price and quantity variances against the PO.
- 5
Human review screen
Show the image beside editable fields, with low-confidence ones highlighted. Corrections are saved as training and rules.
- 6
Post and archive
Create the AP invoice or receipt through the service, then store the image and extraction record against it for audit.
Example flows
Invoice with three-way match
Trigger: A vendor invoice PDF lands in the AP folder.
- OCR and extraction produce header and lines with confidence scores.
- Matcher finds the PO and received quantities.
- Variances above tolerance are flagged for the buyer.
- A clerk reviews the flagged fields and approves.
- AP invoice is posted and the image archived.
Result: Clean invoices post with a glance, and only real variances need attention.
Mill cert to lot record
Trigger: A material test report is scanned with the incoming shipment.
- Heat number, material spec and supplier are extracted.
- System finds the received lot on the receipt.
- Certificate is attached to the lot and mismatches in heat number are flagged.
Result: Traceability documents are linked at receipt, which helps audits and customer certification requests.
Keeping data on-prem
Documents like drawings, certs and invoices are the content many manufacturers cannot send to a public cloud, particularly with export-controlled technical data. Run OCR and extraction on-prem using open-source OCR plus an open-weight vision or language model on your own GPUs. The review screen and matcher run on the internal network beside Epicor, and the only thing that touches the ERP is the final posting call. Air-gapped sites can do the whole pipeline offline, with models loaded from a controlled repository and updated on a schedule.
Security checklist
- Encrypt scans at rest and restrict who can open the archive, since invoices include bank details.
- Never auto-post payments or bank detail changes from extracted text without independent verification.
- Detect duplicate invoices by vendor, number and amount before posting.
- Segregate duties so the person who reviews OCR is not the person who approves payment.
- Keep an audit trail of extraction values, edits and who approved.
Ways to get it done
Use a packaged AP automation product with an Epicor connector
Effort: About 4 to 8 weeks, with per-document licensing.
Mostly invoices, and a vendor that lists support for your Epicor version.
Build in-house with open OCR, a model and the AP web services
Effort: About 8 to 14 weeks to reach reliable vendor matching.
Mixed document types, cert and drawing handling, and a development team.
Partner build with Netray
Effort: Pilot on one document type, usually invoices or certificates.
Controlled data, on-prem requirement and multiple document types.
Pitfalls
- !A correct read on the wrong vendor or PO is the main failure. Invest in matching, not just OCR.
- !Handwritten notes and stamps over text reduce accuracy. Set expectations.
- !Multi-page invoices and credit memos need explicit handling.
- !Unit of measure differences between invoice and PO cause false variances.
- !Skipping a review step to chase straight-through rates leads to wrong postings.
Frequently asked questions
Does Epicor Vantage or Epicor 9 include invoice OCR?
Not as a built-in capability for these versions. You add OCR through a third-party AP product or a custom pipeline that reads documents, matches them to POs and receipts, and posts through the business object web services after review.
What confidence threshold should I use?
Set it per field. Totals and PO numbers deserve high thresholds, descriptions lower ones. Start strict so reviewers see more, then relax for vendors that have proven reliable over a few hundred documents.
Can OCR attach certificates to lots?
Yes. Extract heat or lot numbers from the certificate, match them to the received lot, and attach the document using the attachment feature or a linked store. Flag any mismatch for quality review.
Can drawings be read automatically?
Title block fields such as part number, revision and material can often be extracted, but dimensions and notes are harder. Use it to index and route drawings, and keep engineering approval for anything that changes the part master.
Can this run offline for controlled data?
Yes. Open-source OCR and open-weight models can run entirely on your own hardware with no internet, which suits export-controlled or customer-restricted documents. You are responsible for your own controls, and the architecture supports them.
