From Manual Invoice Entry to Serverless Financial Automation
Invoice Workflow Discovery
We mapped how invoices were received, reviewed, validated, stored, and transferred into financial workflows. This established the required data fields, document types, GST checks, exception rules, access controls, and processing statuses.
Document Intelligence Design
The extraction workflow was designed to support multiple invoice formats, including scanned images, digital PDFs, multi-page documents, tables, and handwritten content. Standard output schemas ensured that data from different layouts entered one consistent financial structure.
Serverless Pipeline Development
We created an event-driven processing architecture using AWS Lambda with Python 3.11, Amazon API Gateway, Amazon Textract, and Amazon Bedrock. Each invoice moves automatically through document intake, OCR, data structuring, validation, storage, and status updates.
Security, Authentication and QA
Amazon Cognito was integrated for secure JWT-based access, while S3 encryption and versioning protected invoice documents and processing history. Quality assurance covered extraction accuracy, schema validation, GST checks, authentication, multi-page invoices, concurrency, and error handling.
Cloud Deployment and Monitoring
The platform was deployed using scalable AWS managed services with Multi-AZ availability and pay-per-use infrastructure. Amazon CloudWatch monitoring and alerts provide visibility into system activity, processing failures, performance, and operational health.
