MANAGED INVOICE PROCESSING SERVICES

IDP Platform with Human-in-the-Loop Exception & Edge Case Handling

Every enterprise AP team that licenses an invoice processing tool and keeps an internal team to handle what the tool cannot (new supplier layouts, bundled PDFs, handwritten invoices, multi-page contracts, foreign-currency invoices) is paying twice for the same outcome.

SunTec India collapses that double-spending model with managed invoice processing services:

  • A proprietary template-free IDP platform (Intelligent Document Processing) that classifies, extracts, and validates documents (including invoices the system has never seen before) and routes confidence-scored exceptions for human review.
  • In-house domain-specialist reviewers who manage edge cases and exceptions while retraining the model for better document processing efficiency in your invoice portfolio.

Outsource invoice processing services to our team and get clean, structured data integrated with your ERP/AP/internal finance tool or system at 5 to 8 seconds per document and 95 to 99 percent post-validation accuracy.

WHERE ENTERPRISE AP AUTOMATION BREAKS

Who Runs the Exception Queue for Your AP Automation Software?

AP automation tools have transformed invoice intake, data extraction, and routing, for the most part. However, in real-world environments, invoices are rarely uniform or predictable. Enterprises continue to face accuracy-related challenges with AP automation when it comes to:

  • Inconsistent vendor invoice formats
  • Non-PO and exception-heavy invoices
  • Poor scan quality or missing fields
  • Contextual validation requirements
  • Master data mismatches
  • Compliance and audit risks

When automation encounters these scenarios, invoices are pushed into exception queues - requiring manual intervention and slowing the entire process. Finance leaders face two structural problems when they buy automated invoice processing solutions to solve this issue. (Yes! This applies even if you buy from leading invoice processing tool vendors!)

Your internal team is not an automation company — they cannot retrain the model the vendor sold you or add new document types without a vendor change request.

Your internal team cannot afford to waste productive hours fixing the exception backlog, since the tool that creates those exceptions is beyond their control.

ACCOUNTS PAYABLE INVOICE PROCESSING: AUTOMATED AND MANAGED

Pull Your Finance Team Out of the Model Retraining and Exception Handling Cycle

We offer a customizable IDP platform and managed invoice processing outsourcing services that enable your AP team to move beyond rigid, template-based OCR invoice processing while adapting to your business rules and custom invoice data validation standards.

Template-Free Deep Learning Document Extraction

Processes invoice layouts that the system has never seen before with significant precision. No need to maintain vendor-based templates. The model improves on every new format it encounters.

Cognitive Classification with Confidence Scoring

Identifies document type from content alone (invoice, PO, credit memo, statement) and routes anything below the classification confidence threshold for human review.

Configurable Human-in-the-Loop Routing

Domain specialists handle exceptions. Routing logic is defined by the client’s selection from three review modes per document type: always-in-the-loop, selective routing below a confidence threshold, or never-in-the-loop.

Multi-Field and Multi-Language Support

Extracts text, numbers, dates, currency, tables, signatures, barcodes, and handwriting across 20+ major global languages and character sets in a single pass.

Complex Table and Line-Item Extraction

Reconstructs multi-page tables, merged cells, wrapped text, and embedded sub-totals at line-level fidelity, including matching each line back to its purchase order.

Cross-Referential Validation Engine

Runs 3-way matching in accounts payable (invoice / PO / goods receipt), duplicate detection, vendor master lookup, and format checks. Validation logic can be configured according to custom business rules.

Multi-OCR Convergence Engine

Runs each document through multiple OCR engines simultaneously, then selects the highest-confidence output to resolve character-level ambiguity that single-engine OCR misses.

Multi-Channel Document Ingestion

Accepts invoices via most ingestion channels, including email, SFTP, REST API, AWS S3, Azure Blob Storage, and Google Cloud Storage. Handles PDF, TIFF, JPEG, PNG, Word, Excel, and e-invoices with equal accuracy.

Continuous Retraining Loop

Every correction made to the processed invoices by a human reviewer is fed into the retraining engine. The model improves on your actual invoice document portfolio over time, not on a generic training set.

Pre-Built ERP and AP Platform Connectors

Native integrations with SAP, Oracle, NetSuite, Microsoft Dynamics, Sage, Workday, QuickBooks, and custom connectors for proprietary systems. Custom format delivery (CSV, JSON, XML, IDoc, BAPI) that matches downstream system requirements.

Compliance-Grade Security and IP Handling

Encryption at rest and in transit, PII detection and masking, role-based access, and tamper-evident audit logs. ISO 27001, SOC 2, HIPAA, and GDPR aligned intelligent document processing.

Real-Time Performance Monitoring via IDP Dashboard

Live view of processing volume (documents processed per day/week/month), average turnaround, accuracy over time, straight throughput (STP) rate, and exception rate by document type.

OUR IDP + HITL PROCESS

Outsource Invoice Processing Services with Expert Oversight

Deploying automation shouldn't mean forcing your vendors to change how they send bills/receipts or leaving your team to clean up automated invoice data extraction errors. True accounts payable transformation requires a solution that handles the messy realities of corporate billing without sacrificing control. That is what you get with our invoice processing company- an intelligent, end-to-end invoice pipeline built for high-volume AP operations.

Outsource Invoice Processing
[1]

Multi-Channel Invoice Ingestion

Suppliers and vendors will not change their submission practices to align with a buyer’s automation. So our IDP platform accepts every bill they send via email, SFTP, API, or cloud storage, in TIFF, JPEG, PNG, Word, Excel, etc. formats.

[2]

Cognitive Invoice Document Classification

Each document is classified into categories such as invoices, POs, credit memos, statements, remittances, etc. Documents below the confidence score threshold are routed for human review before data extraction begins.

[3]

Template-Free Data Extraction

Our intelligent document processing platform extracts header fields, line items, tables, signatures, barcodes, and handwriting through multi-OCR convergence, ensuring high data-extraction accuracy.

[4]

Invoice Data Validation using Business Rules

Extracted data is validated against PO records, vendor master, historical payments, format rules, and client-specific business rules. Any exceptions are flagged with a reason for further review.

[5]

HITL Review and Model Retraining

Documents below the configured confidence threshold are routed to in-house domain reviewers. Every correction is logged and fed back into the retraining engine to improve invoice processing efficiency.

[6]

Data Integration into Client ERP/AP Systems

Clean invoice data is formatted into IDoc, BAPI, REST JSON, CSV, XML, or custom formats per ERP and per buyer, and integrated via pre-built connectors into the client's ERP systems or AP automation and procurement platforms.

FAQ- FREQUENTLY ASKED QUESTIONS

Invoice Processing Services

Yes. An accounts payable automation software requires human intervention, review, and correction because its accuracy rates can slip at multiple touchpoints:

  • If a vendor changes their layout, uses an unusual font, or sends a blurry scanned PDF, the software’s optical character recognition (OCR) can misread the data.
  • The software sees a string of text and looks for an exact match in the database. If it can't find it, it stalls or hallucinates.
  • If the Purchase Order (PO), Receiving Log, and Invoice don't match down to the penny, the system flags a mismatch, even though it can't usually explain why.
  • Translation software frequently misses regional accounting idioms, tax structures (such as complex VAT or GST rules), and local compliance nuances.
  • AI is great at spotting statistical anomalies, but phishing and invoice fraudsters frequently submit fake invoices that perfectly mimic a company's standard layout and pass all basic software validation rules.

An IDP platform is fundamentally built on AI, OCR, and Large Language Models (LLMs)—meaning ours is just as prone to the same errors, hallucinations, and layout confusion as any other automated AP software. However, here’s how we ensure a 95-99% accuracy rate post-validation across our managed invoice processing service model.

  • A Managed Service: When our IDP platform fails or encounters a messy layout, the exception is routed to SunTec India's domain-specific human reviewers, who fix the error, map the data, and resolve the discrepancy behind the scenes.
  • Clean Data Delivery: The software processes the easy 80% of invoices at lightning speed, while our team of specialists manually processes and validates the remaining 20% complex cases. By the time the data is pushed into your ERP (such as SAP, Oracle, or NetSuite), it has achieved 95-99% accuracy.
  • Continuous Invoice-Type-Specific Model Training: The IDP platform continuously trains on human reviews, becoming smarter and more efficient at handling your specific vendor invoice patterns over time.
  • Custom AI Workflows: Our invoice processing services are supported by a dedicated in-house technology division that designs, develops, and customizes automation around real-world AP environments (using technologies such as OCR, RPA, Agentic AI, and Deep Learning). Our IDP platform can be customized to absorb your specific industry's compliance and layout nuances.

Additionally, you get a team responsible for conflict resolution, domain experts to spot behavioral anomalies across invoices, and a dedicated PM accountable for the entire process, giving you the cost benefits of automation without the operational headache of managing software errors.

Yes. You can, because our enterprise invoice processing services offer two distinct categories of support to AP teams:

  • HITL Invoice Data Processing: In-house experts process the documents your existing tool flags as exceptions.
  • Full-Stack IDP Platform with HITL Exception Handling: Our pipeline replaces any existing invoice processing tools your team uses while also managing exceptions and edge cases, and training our IDP platform on the types of invoices your business handles, improving downstream efficiency over time.

No. On the contrary, your control and visibility increase. Our IDP platform features a live dashboard that lets you track every document in the pipeline, including status, confidence score, reviewer assignment, and validation outcome. You can modify role-based access controls, create custom business rules and validation logic, and monitor the audit trail for processed invoices. Additionally, you can contact the dedicated project manager assigned to you for any performance, accountability, or process-related issues, further strengthening your control over the process without adding any overhead to your finance teams.

Our IDP platform can accept documents in multiple formats, including PDF (digital and scanned), TIFF, JPEG, PNG, Word, Excel, email body, e-invoices (PEPPOL and UBL), EDI 810, and bundled multi-page documents. Acceptable document ingestion channels include email, SFTP, REST API, AWS S3, Azure Blob, and Google Cloud Storage. The platform is template-free, so any layout the system has not seen before is processed and added to the training set.

We ensure invoice data security via

  • Encryption in transit and at rest
  • PII detection and masking before any HITL reviewer sees the document
  • Role-based access controls administered through the IDP dashboard
  • Audit logs of every automated decision and every human override
  • ISO 27001, SOC 2, HIPAA, and GDPR aligned processes
  • Data residency options include our region, client region, or client-hosted infrastructure

Yes. Cross-referential invoice data validation runs 3-way matching at the line level (invoice to PO to goods receipt), duplicate detection on configurable rules (vendor plus invoice number plus amount plus date), vendor master lookup against the approved supplier list, format validation (date, IBAN, VAT ID, GSTIN), and cross-field arithmetic checks. Clients can configure custom business rules directly using the IDP platform.
