Overview of Project ☁️

This project focuses on automating receipt processing using AWS services. Instead of manually handling receipts which can be time-consuming, error-prone, and difficult to scale—this system extracts structured data from receipts and stores it efficiently for record-keeping and auditing.

The architecture consists of:

• Storage Layer: Amazon S3 stores receipt images and PDFs.
• Processing Layer: Amazon Textract extracts text from receipts using AI-powered OCR.
• Database Layer: DynamoDB stores the extracted data in a structured format.
• Notification System: Amazon SES sends email alerts with receipt details.
• Compute Layer: AWS Lambda automates the workflow by processing the receipts in real-time.

Steps to be performed 👩‍💻

In the next few lessons, we'll be going through the following steps.

1. Storage and Database Setup: S3 bucket and DynamoDB Table
2. Notification Setup: Configuring Amazon SES
3. Processing Setup: Creating a Lambda function
4. Integration and Testing

Clean Up 🗑️

1. Delete S3 Bucket:

• Remove all uploaded receipt files and then delete the bucket.

2. Stop Textract Processing: 

• Ensure no further API calls are made to prevent extra costs.

3. Delete DynamoDB Table: 

• Remove stored receipt data and then delete the table.

4. Disable SES Notifications: 

• If SES was configured, remove verified email addresses.

5. Remove IAM Roles and Policies: 

• Delete the IAM role created for the Lambda function.
