White-Label Handwriting-to-Excel SaaS

Build a Complete White-Label AI Handwriting & Document-to-Excel SaaS

I want a complete, production-ready web-based subscription service under my own brand.

Core requirements

1. Accept photos and PDFs of handwritten and printed slips.
2. Read Hindi handwriting, English handwriting, and mixed Hindi-English handwriting.
3. Automatically identify document/slip types.
4. Automatically detect fields and create a new structured table for an unknown slip type.
5. When similar slips arrive later, automatically append their data to the correct existing table.
6. Export and maintain Excel files automatically.
7. Provide separate client accounts, isolated data, and dashboards.
8. Include admin panel, client management, monthly subscriptions and usage tracking.
9. Fully white-label: my logo, brand name and domain.
10. Easy client interface: upload a photo and receive structured data without configuring templates or columns.

Strict technical and licensing conditions

- Fully open-source software.
- Commercial use and resale as a subscription service must be permitted.
- All code and model weights must have permissive commercial licenses (MIT, Apache 2.0 or BSD).
- No paid OCR APIs, proprietary models, or mandatory third-party subscriptions.
- Self-hosted deployment.
- Complete source code and deployment documentation must be handed over.

Accuracy and testing

Before final delivery, test with real handwritten and printed Hindi-English slips, including mixed-language documents and previously unseen formats.

Provide a test report with field-level accuracy, error handling and confidence scores. Uncertain values must be flagged rather than silently guessed.

Deliverables

- Complete working SaaS application.
- Source code and model files.
- Admin and client dashboards.
- Excel automation.
- Subscription and branding system.
- Installation and deployment.
- Testing and bug fixing.
- Ownership and commercial usage rights.

Please quote a fixed total project price, estimated completion time, and a breakdown of milestones. Do not submit a proposal for OCR alone; I need the complete working subscription service.
