How to choose the right IDP tool for your business

Selecting the best intelligent document processing (IDP) tool depends on far more than just accuracy.

Think of features, pricing, and scalability with your company’s specific context.

Here are some key factors to consider when evaluating your options.

Volume counts: assess it before choosing

If you're a freelancer or small business dealing with a few invoices per week, a lightweight, affordable software plan is ideal.

However, if you're processing thousands of documents across multiple departments or locations, you might want to look for plans that are better suited to an enterprise-grade scalability and custom workflows.

Compatible is good– flexible is great

Look for tools that integrate smoothly with your existing stack: ERP, CRM, accounting, and workflow platforms.

High flexibility means not just having preset integrations with the major software out there, but also the possibility of setting up custom connections with low effort.

For instance, Procys offers seamless integration with systems like QuickBooks, Salesforce, and Holded, while others provide limited tool-specific pipelines for enterprise setups.

It shouldn’t be a long way to automate

Some platforms prioritize intuitive UX and low setup time, which are perfect for businesses without an internal IT department.

In contrast, other platforms drastically deteriorate the ease of their setup when it comes to legacy-grade workflows. 

In such cases, look for an excellent support team to guide you through the specifics of the tool.

Better safe than fined

If you're in a highly regulated industry, like finance, healthcare, or government, you’ll want strict compliance features like SOC 2, HIPAA, GDPR, or PCI DSS.

Data – whatever type of – must be secure at every stage of the operational flow or else, not just the revenue, but the reputation and the legal compliance of your business will suffer.   

Future trends in intelligent document processing

As businesses continue to prioritize automation, intelligent document processing (IDP) tools are evolving beyond OCR to become strategic enablers of end-to-end workflow transformation. 

Here are some of the most impactful trends shaping the future of IDP.

AI-first automation will become the norm

Traditional OCR is being replaced by deep learning models that understand context, detect anomalies, and improve over time.

Modern platforms are leading this shift with AI-first frameworks that don’t rely on templates and can handle unstructured, multilingual, and inconsistent data with high accuracy.

Real-time decisioning and validation

Next-gen IDP tools are expected to embed real-time validation logic, enabling on-the-fly decision-making.

For example, payment approvals, risk flags, or tax code checks will happen automatically during document processing, minimizing human review and speeding up operational workflows.

Hybrid models: automation plus human-in-the-loop

While full automation is the goal, sensitive industries like finance and healthcare can still benefit from hybrid models.

Combining AI with human validation ensures high accuracy where regulatory compliance is critical, although sometimes, it also means longer processing times.

Plug-and-play in intelligent document processing tools

Businesses increasingly demand IDP tools that "just work" with their tech stack, with no custom coding required.

This is pushing vendors to offer native integrations, no-code APIs, and connectors for popular tools.

In other cases, IDP features are being embedded directly into vertical-specific platforms—like ERP systems, banking software, or e-commerce solutions.

Expect to see tighter product partnerships and white-label deployments of IDP in the coming years.

Conclusion

Navigating through different intelligent document processing tools can dramatically boost your team's productivity, reduce manual errors, and free up valuable time for strategic work.

Yet, choosing the best fit means considering not only the tool's accuracy, but also its adaptability to your business size, tech ecosystem, and budget.
