Automated Document Processing: How PEDIF's Fingerprint Technology Converts PDFs to EDI with 100% Accuracy

Automated document processing is the end-to-end conversion of business documents, such as PDF invoices and purchase orders, into structured electronic formats (EDI, XML, e-invoice) that flow directly into target business systems without manual data entry. PEDIF achieves this using document fingerprint technology: a unique layout profile created once per document type that enables 100% accurate, no-touch data extraction for every subsequent document matching that layout.

Automated document processing sits at the intersection of operational efficiency and business growth. Companies that still rely on manual data entry to handle incoming invoices, purchase orders, and delivery notes are losing hours, introducing errors, and creating compliance risk every single day. As the volume of B2B documents grows, the cost of that inefficiency scales with it.

PEDIF was built to eliminate this problem entirely. Developed by Supedio GmbH in Dresden, Germany, PEDIF is not an OCR tool or a generic AI platform (following OCR/AI). It is an Augmented Intelligence solution that uses a proprietary document fingerprint to convert PDF business documents into fully compliant EDI and e-invoice formats with guaranteed 100% data accuracy, no manual correction, and near real-time throughput.

This guide explains exactly how PEDIF's approach to automated document processing works, why it outperforms conventional OCR-based alternatives, and what it means practically for procurement, accounts payable, and supply chain teams.

What Is Automated Document Processing?

Automated document processing: the use of software to extract, convert, and deliver structured data from business documents without manual intervention.

Automated document processing is the practice of using software to handle the full lifecycle of a business document from receipt through data extraction, format conversion, validation, and delivery into a target system without requiring human involvement in between.

In a B2B supply chain context, this means that when a supplier sends an invoice as a PDF, the receiving company's system can automatically extract every relevant data field, convert it into the required electronic format (such as XRechnung, ZUGFeRD, or an EDIFACT message), validate it against business rules, and push it into their ERP or accounting platform. No one opens the PDF. No one types anything. No one checks a dashboard.

This level of automation is what PEDIF delivers, and the technology it uses to achieve it is what sets it apart from every OCR/AIOCR-based tool on the market.

Why OCR/AIOCR-Based Document Processing Falls Short

Optical Character Recognition (OCR) has been the dominant technology for document digitisation for decades. It works by scanning a document image, recognising characters, and attempting to reconstruct the text. For many use cases, this is adequate. For high-stakes B2B document processing, it is not.

The fundamental problem with OCR/AIOCR is that it reads every document as if it were seeing it for the first time. Layout variations between suppliers, print quality differences, unusual fonts, or slight formatting changes can all degrade accuracy. Even a 2% error rate, which most OCR/AIOCR tools would consider excellent, means 200 incorrect records in every 10,000 lettersdocuments processed, what corresponds to about 30 errors per single page. Those errors cascade: misrouted payments, failed compliance checks, disputed invoices, and strained supplier relationships.

OCR/AIOCR vs. PEDIF Document Fingerprint Technology

PEDIF's document fingerprint technology sidesteps this problem entirely. Rather than trying to read a document, it recognises it and extracts data with the precision of someone who has seen exactly that document layout hundreds of times before.

How PEDIF's Document Fingerprint Technology Works

The document fingerprint is the core innovation behind PEDIF's approach to automated document processing. Just as a human fingerprint uniquely identifies a person, a PEDIF document fingerprint uniquely identifies a specific document layout, for example, the invoice template used by a specific supplier.

Stage 1: Fingerprint Creation (One-Time Setup)

When PEDIF encounters a document layout for the first time, a fingerprint is created. This combines human expertise verifying the data fields and their locations within the document, with intelligent analysis of the layout structure. The fingerprint captures exactly where each data field sits: invoice number, date, line items, amounts, VAT, supplier details, and every other relevant field.

This is a one-time process per document layout. Once the fingerprint exists, it never needs to be created again for that layout.

Stage 2: Automated Processing (Every Subsequent Document)

Every document that matches a known fingerprint is processed automatically. There is no OCR/AIOCR, no probabilistic reading, no interpretation. PEDIF knows exactly where each field is located and extracts it with 100% accuracy every time, at any scale.

The Six-Step Processing Pipeline

1. PDF document received via email, upload, SFTP, or API connection

2. Document matched to its fingerprint profile

3. All data fields were extracted with 100% accuracy

4. Target format generated: XRechnung, ZUGFeRD, PEPPOL, EDIFACT/EANCOM, XML, CSV, or other

5. Output validated against compliance rules and business logic

6. Compliant message transmitted to the target system or EDI network

From receipt to delivery, this entire pipeline runs without human involvement. Teams that previously allocated staff to document handling find those resources freed for higher-value activity.

PEDIF's Three Core Products for B2B Document Automation

1. PDF to E-Invoice - Compliance-Ready in Any Format

PEDIF's PDF to E-Invoice product converts supplier PDF invoices into any required e-invoice standard. As EU member states progressively mandate electronic invoicing for both public procurement and B2B transactions, the ability to produce compliant e-invoices automatically is becoming a business-critical requirement rather than an efficiency gain.

Supported e-invoice standards include:

• XRechnung, the mandatory German public sector e-invoice format

• ZUGFeRD, the hybrid PDF/XML e-invoicing standard for cross-sector use

• PEPPOL BIS Billing: the pan-European e-procurement network standard

• EDIFACT INVOIC / EANCOM global EDI standard used widely in retail and logistics

2. PDF to E-Order - Automating the Purchase Order Cycle

Purchase orders are among the highest-volume documents in any procurement operation, and they carry significant risk if data is transcribed incorrectly. PEDIF's PDF to E-Order product converts PDF purchase orders from buyers into structured electronic order messages that flow directly into supplier ERP or order management systems, eliminating manual order entry entirely.

This cuts order processing time from hours to seconds and eliminates the order entry errors that cause fulfilment delays and invoice disputes downstream.

3. X to PDF - Bidirectional Document Conversion

PEDIF also operates in reverse. The X to PDF product converts structured data from ERP outputs, EDI messages, or other system-generated formats into compliant PDF documents for partners who require them. This means PEDIF handles both sides of the document exchange, making it a complete B2B document automation solution rather than a one-directional converter.

21 Supply Chain Document Types: Complete Workflow Coverage

One of PEDIF’s key differentiators in automated document processing is the breadth of its document support. The platform is not an invoice-only tool. It handles 21 supply chain document types, enabling automation across the full procurement and logistics cycle.

This breadth of coverage means businesses can automate their entire inbound and outbound document workflow through a single platform, rather than deploying separate tools for invoices, orders, and delivery documents.

Supported Output Formats and EDI Standards

PEDIF generates output in all major electronic document and EDI standards used in European and international B2B commerce. This ensures that whatever format a trading partner requires, PEDIF can produce it directly from the source PDF.

The Real-World Benefits of PEDIF's Automated Document Processing

✓  100% Data Accuracy - Guaranteed

This is not a marketing claim. It is the logical outcome of PEDIF’s fingerprint-based extraction model. For every document that matches a known fingerprint, every data field is extracted correctly because the system knows exactly where to find it. Unlike OCR/AIOCR, which produces probabilistic results that vary with document quality, PEDIF's output is deterministic and consistent.

For e-invoicing specifically, this matters enormously. A single incorrect VAT figure or IBAN on an XRechnung can trigger a compliance failure, a payment hold, or a supplier dispute. With PEDIF, those outcomes are eliminated by design.

⏱  Near Real-Time Processing at Any Scale

Once fingerprints are in place, PEDIF processes documents automatically and at speed. Invoices that previously waited in a queue for manual processing are converted, validated, and transmitted in near real-time. This accelerates payment cycles, improves cash flow visibility, and enables procurement teams to make faster, data-driven decisions.

€  Substantially Lower Cost Than OCR/AIOCR or Traditional EDI

Traditional EDI implementation requires significant investment in software, infrastructure, mapping specialists, and ongoing maintenance. OCR/AIOCR solutions carry licensing costs and correction workflow costs. PEDIF offers an alternative that achieves higher accuracy than OCR/AIOCR at a fraction of the cost of traditional EDI, with no requirement for in-house EDI expertise.

✔  Built-In E-Invoicing Compliance

With EU e-invoicing mandates expanding across member states, compliance is no longer optional for businesses trading across borders or with public sector entities. PEDIF includes a built-in validation engine that checks every generated document against the relevant standard before transmission, ensuring that XRechnung, ZUGFeRD, and PEPPOL outputs are compliant by default.

♻  Significantly Lower Environmental Impact

PEDIF’s Augmented Intelligence approach generates approximately 20 times less CO₂ than conventional AI-based document processing solutions, and around 80 times less than large language model (LLM) based alternatives. For businesses with scope 3 emissions commitments or sustainability reporting obligations, this is a measurable differentiator when evaluating technology vendors.
