Generic OCR Fails on Indian Invoices. Compliance-Aware Capture Doesn't.
Standard OCR tools achieve 70-75% accuracy on Indian invoices because they don't understand GST fields or format diversity. IQInvoice extracts all mandatory GST fields from any invoice format - email, PDF, scan, portal - with 95%+ accuracy. Data is ready for compliance checks and ERP posting without re-keying.

The standard OCR problem is not accuracy - it's context.
Invoice Format Chaos
Your vendors send invoices in dozens of formats - e-invoices from large suppliers, PDFs from mid-market vendors, scanned paper from distributors. Each format has a different structure. Generic OCR treats each one the same way and misses context-specific fields like IRN and QR codes.
GST Field Complexity
Indian invoices have mandatory GST fields that don't exist in Western formats: GSTIN (vendor tax ID), IRN (Invoice Reference Number), QR code, e-invoice compliance markers. Generic OCR has no training on these fields and often misreads GSTIN checksums, IRN formats, and tax breakdowns.
Language and Typography
Invoices mix English and Hindi, use multiple font sizes, and embed logos. Character recognition fails at font boundaries. Line item totals don't match header totals. Amount fields use both words and numerals. Generic OCR treats each problem as a separate recognition failure.
Silent Failures
70-75% accuracy sounds acceptable until you scale. At 500+ invoices per month, that means 125-150 invoices per month with extraction errors. Those errors cascade downstream - wrong vendor matches, wrong line items, wrong tax amounts. They're often not caught until audit.
How IQInvoice Captures Invoices
Compliance-aware extraction, trained on Indian invoice formats.
Receive from Any Source
Invoices arrive via email, vendor portal, direct upload, or API. Format doesn't matter - e-invoice XML, PDF digital, scanned paper, all processed the same way.
Extract All GST Fields
Compliance-aware extraction identifies and pulls all mandatory GST fields: vendor GSTIN, invoice number, date, line items, tax breakdowns, IRN, QR code, e-invoice compliance markers. Trained on thousands of Indian invoice samples - not generic documents.
Validate Structure and Data
Extracted data is validated for completeness: all required fields present, format correct, math checking (line totals match header, tax matches invoice amount). Invalid or missing data routes to exception handling - never silently passes through.
Bridge to Compliance Gate
Captured and validated data flows directly into IQInvoice's compliance gate. GSTIN validation, IRN/QR verification, PAN/MCA checks, MSME flagging - all run before ERP entry. Only clean, compliant invoices post to your books.
What Happens After Capture
Extraction is step 1. Compliance is where the money is made.

Frequently Asked Questions
Why does generic OCR fail on Indian invoices?
Standard OCR tools are trained on Western invoice formats. Indian invoices have mandatory GST fields (GSTIN, IRN, QR codes), mixed Hindi/English text, and come in dozens of vendor formats. Generic OCR achieves 70-75% accuracy on these invoices. Compliance-aware systems trained on Indian formats achieve 95%+ accuracy by understanding the structure and validating data against GST rules in real time.
What formats does IQInvoice support?
IQInvoice captures invoices from any format: e-invoices (XML), PDFs (digital or scanned), vendor portals, email attachments, and direct uploads. All formats are processed the same way - all GST-mandatory fields extracted, validated, and prepared for approval routing. No re-keying. No manual format conversion.
How is invoice capture different from just OCR?
OCR reads text. Invoice capture goes further - it understands invoice structure, extracts mandatory GST fields (GSTIN, IRN, line items, tax breakdowns), validates the data makes sense, and bridges into compliance checking. IQInvoice extracts structured data, not just raw text. What comes out is ready for ERP posting or compliance validation - not manual correction.
What happens if the OCR fails to capture a field?
If a field is missing or unreadable, IQInvoice flags it in the exception queue. Your AP team can override with documented justification, reject and request a corrected invoice, or route for manual review with the original document attached. Every decision is logged. There is no silent failure - missing data is always surfaced.
Can IQInvoice handle handwritten or poor-quality scans?
Compliance-aware OCR trained on Indian invoice formats handles most poor-quality scans. However, invoices that are severely damaged, illegible, or primarily handwritten may need manual review. These edge cases route to your exception queue automatically - your AP team reviews the original document and decides whether to process or reject. The system is designed to be 95%+ automated but transparent about exceptions.
