Top Free Invoice Parser tools, APIs, and Open Source models

What is Invoice Parser API?

The Invoice Parser, also called OCR Invoice API, can extract data from an invoice in a structured format comprising the customer's name, billing address, line items, quantities, prices, total amounts due, and other relevant information.

By combining Optical Character Recognition (OCR) technology with other advanced tools, including machine learning and natural language processing (NLP), Invoice Parser API can precisely collect data from various formats (PDF, scanned image, etc.), guaranteeing the significance of the extracted information, thus freeing up valuable time and resources for businesses.

Invoice Parsing APIs are frequently utilized in accounts payable departments to automate the invoice processing procedure and lessen the requirement for manual data input.

Top Open Source (Free) OCR Invoice Parser models on the market

For users seeking a cost-effective engine, opting for an open-source model is recommended. Here is the list of the best Invoice Parser Open Source Models:

1‍. InvoiceNet

Deep neural network to extract intelligent information from invoice documents.

2. invoice2data

Open Source Library that helps you in invoice parsing.

3. veryfi-python

This is the veryfi open source Python model that helps in various OCR tasks. This can also be used for invoice parsing.

4. Invoiceable

Invoiceable is a free and open-sourced Flask application that uses AI, Tesseract OCR, and the open-sourced machine learning model to parse invoices, documents, résumés, and more.

Cons of Using Open Source AI models

‍While open source models offer many advantages, they also have potential drawbacks and challenges. Here are some cons of using open source models:

  • Not Entirely Cost Free: Open-source models, while providing valuable resources to users, may not always be entirely free of cost. Users often need to bear hosting and server usage expenses, especially when dealing with large or resource-intensive data sets.
  • Lack of Support: Open source models may not have official support channels or dedicated customer support teams. If you encounter issues or need assistance, you might have to rely on community forums or the goodwill of volunteers, which can be less reliable than commercial support.
  • Limited Documentation: Some open source models may need more complete or better-maintained documentation. This can make it difficult for developers to understand how to use the model effectively, leading to frustration and wasted time.
  • Security Concerns: Security vulnerabilities can exist in open source models, and it may take longer for these issues to be addressed compared to commercially supported models. Users of open source models may need to monitor for security updates and patches actively.
  • Scalability and Performance: Open source models may not be as optimized for performance and scalability as commercial models. If your application requires high performance or needs to handle a large number of requests, you may need to invest more time in optimization.
