Executive Summary
Accomation.io, a fast-growing accounting automation platform, needed to scale invoice processing without increasing manual workload. Finance teams were spending hours extracting GST, PAN, line items, and totals from unstructured invoices and manually entering data into ERP systems like Tally and Saral.
Calyza Tech designed a fully serverless, AI-driven invoice processing solution on AWS, combining intelligent OCR with Generative AI to transform invoices into structured JSON in minutes.
The Challenge: Manual Processing at Scale
The Solution
We built a scalable, event-driven architecture using:
The system automatically extracts invoice data, validates GST/PAN details, standardizes formats, and generates schema-compliant JSON.
We built a scalable, event-driven architecture using:
- Amazon API Gateway – Secure invoice ingestion via REST APIs
- Amazon Cognito – JWT-based authentication & role-based access
- AWS Lambda – Serverless processing engine
- Amazon Textract – Intelligent OCR for text, tables, and line items
- Amazon Bedrock – Generative AI structuring and normalization
- Amazon S3 – Secure storage of structured outputs
- AWS CloudTrail – Audit logging and traceability
The system automatically extracts invoice data, validates GST/PAN details, standardizes formats, and generates schema-compliant JSON for ERP integration.
Key Results
Processing time dropped from hours to minutes, enabling finance teams to focus on exception management and strategic analysis instead of manual data entry.
Business Impact
- Near real-time invoice processing
- Improved compliance and audit readiness
