Q1: Which Indian invoice formats does your OCR API support?

A: Our Invoice OCR API supports all common Indian invoice formats including GST-compliant invoices, e-invoices with IRN and QR codes, PDFs, scanned images (JPEG, PNG), and multi-page documents. It accurately extracts GSTIN, PAN, HSN/SAC codes, CGST/SGST/IGST breakdowns, and line items regardless of vendor layout or template.

Q2: Can the API handle multiple invoices at once?

A: Yes. Batch processing is fully supported, allowing you to submit hundreds of invoices in a single API call. This is ideal for accounting firms, ERP systems, and enterprise finance teams processing high volumes during GST filing periods.

Q3: Is the extracted data compliant with Indian GST regulations?

A: Yes. The API is built for India's compliance landscape — it validates GSTIN format, identifies CGST/SGST/IGST/IGST/cess amounts, and handles PAN and PII redaction in line with Indian data protection norms. Every extracted record maintains a full audit trail suitable for GST department scrutiny.

Q4: What is the accuracy rate of the Invoice OCR API?

A: The API achieves high field-level accuracy on standard printed invoices, including complex Indian formats with mixed layouts, regional language text, and low-resolution scans. Accuracy varies by document quality — clean digital PDFs consistently outperform degraded scans. Contact us for benchmark results on your specific invoice types.

Q5: What is the typical processing time per invoice?

A: Most invoices are processed within 2–5 seconds per document via the standard API endpoint. Batch jobs are processed asynchronously with webhook callbacks, so your system isn't blocked waiting for large volumes to complete.

Q6: Which accounting and ERP systems can I integrate this with?

A: The API outputs structured JSON, XML, or CSV — making it compatible with any ERP or accounting platform including Tally, Zoho Books, SAP, Oracle, QuickBooks, and custom-built fintech systems. FintegrationFS also provides integration support if you need help mapping extracted fields to your existing schema.

Q7: Do you offer a sandbox or free trial environment?

A: Yes. You can schedule a demo to see the API in action against your own invoice samples before committing. Reach out via the contact form and we'll set up a test environment scoped to your document types and volume requirements.

Q8: How is sensitive data like PAN and GSTIN handled securely?

A: All data is transmitted over HTTPS with AES-grade encryption at rest. The API includes built-in PII redaction for PAN numbers, bank account details, and email IDs. Access is role-controlled, and every API call is logged with timestamps for audit purposes.

Q9: Can the API process invoices in Hindi or other Indian regional languages?

A: Yes. The OCR engine supports multi-language recognition covering English, Hindi, and other Indian regional languages commonly found on vendor invoices, purchase orders, and tax documents.

Q10: How is FintegrationFS Invoice OCR API different from generic OCR tools like Google Vision or AWS Textract?

A: Generic OCR tools extract raw text — they don't understand Indian invoice structure, GST tax logic, or GSTIN validation. Our API is purpose-built for the Indian compliance context: it knows the difference between CGST and IGST, validates GSTIN format in real time, maps HSN/SAC codes, and outputs data ready for Indian accounting workflows — without requiring custom templates or post-processing.
