Common Mistakes to Avoid
The most common buying mistakes come from picking an OCR tool that cannot produce the structure, validation, or output format your workflow requires.
Choosing plain text OCR when your workflow needs key-value and table structure
Avoid selecting tools that only extract unstructured text when you need fields and tables because Amazon Textract, Microsoft Azure AI Document Intelligence, and Google Cloud Document AI are built for layout-aware form and table extraction. Use those tools when downstream automation depends on key-value fields rather than raw text.
Underestimating setup effort for structured extraction systems
Avoid assuming document AI is plug-and-play when you need custom accuracy because Google Cloud Document AI and Microsoft Azure AI Document Intelligence require engineering work for dataset preparation and customization. ABBYY FlexiCapture also requires process design and OCR model configuration for classification and validation workflows.
Using generic OCR when math structure is the core requirement
Avoid using general OCR tools for formula digitization when you need editable LaTeX output because Mathpix is tuned for math notation like fractions and superscripts. This prevents manual rewriting of equations after OCR.
Ignoring validation and confidence triage for high-volume business capture
Avoid fully automating capture without quality controls because ABBYY FlexiCapture provides document-level quality verification with configurable validation and reprocessing logic. Amazon Textract and Google Cloud Document AI provide confidence scores that support triage of low-quality extracted fields.
