What OCR API should I use for receipts, forms, and IDs in one workflow?

If you need one OCR workflow that handles receipts, forms, and IDs, the best choice depends on whether you want highest extraction accuracy, easy integration, or lowest cost.

Best all-around choices

1. Google Cloud Document AI

Best for: unified document processing across many document types

• Strong at receipts, invoices, forms, IDs
• Good structured extraction, especially with its specialized processors
• Easy to build a single pipeline with document classification + extraction
• Works well if you want one platform for multiple document types

Why choose it:
If you want to avoid juggling separate OCR tools, Document AI is one of the strongest “single platform” options.

2. AWS Textract

Best for: forms and key-value extraction, with solid general OCR

• Very good at forms and tables
• Can extract text, key-value pairs, tables
• Often used in production workflows for document ingestion
• IDs and receipts can work, but specialized extraction may be less polished than dedicated processors elsewhere

Why choose it:
Good if you already use AWS and want a reliable workflow without much model tuning.

3. Azure AI Document Intelligence

(formerly Form Recognizer) Best for: forms, receipts, IDs, and custom document models

• Has built-in models for receipts and IDs
• Strong for forms and custom extraction
• Good developer experience and enterprise features
• Useful if you want to train custom models for edge cases

Why choose it:
Probably the best “single vendor” option if you want receipt + ID + form extraction in one stack.

My recommendation

If you want one API for all three document types, I’d rank them like this:

1. Azure AI Document Intelligence — best balance for receipts, IDs, and forms
2. Google Cloud Document AI — strongest overall document platform
3. AWS Textract — very good for forms, strong general OCR, especially in AWS ecosystems

Practical workflow suggestion

A robust production setup is usually:

1. Detect document type
   • receipt / form / ID
2. Route to the best model
   • receipt model
   • ID model
   • form model
3. Post-process
   • normalize dates, amounts, names
   • validate fields

This usually performs better than a single generic OCR pass.

If you want the simplest answer

• Best single API: Azure AI Document Intelligence
• Best overall platform: Google Document AI
• Best for forms-heavy AWS stacks: AWS Textract

If you want, I can also give you:

• a side-by-side feature comparison
• a cost/latency breakdown
• or a recommended architecture for your exact use case (mobile app, backend batch, or real-time API).
