THE CHALLENGE

The Client Faced Slow, Inconsistent Document Reviews While Developing Their SaaS Platform for Contract Analysis

The client was developing a SaaS platform to streamline contract and document analysis for US construction and legal teams. However, their existing manual review process was slow, inconsistent, and difficult to scale, causing delays in client request processing and quality issues.

To enhance their product’s efficiency and value, they needed to integrate an LLM-based solution that could automatically analyze entire document sets, extract key insights, and deliver faster, more reliable results within their SaaS environment.

Model Training and Quality Assurance

Achieving the required accuracy for diverse legal and construction documents demanded multiple training iterations and prompt engineering refinement.

Speed Optimization

The LLM needed to deliver fast analysis results without compromising quality, ensuring seamless integration into the client’s SaaS workflow.

Document Type Differentiation

The system had to correctly identify and analyze different contract types (e.g., NDAs, change orders, project agreements), each requiring unique logic and prompts.

THE SOLUTION

Implementing an LLM-Powered Engine with Decision-Tree Logic for Automated, Structured Contract Analysis

To address these challenges, we implemented an LLM enhanced with decision-tree logic that applied specific prompts for each contract type. Once a user uploaded a document, the system automatically analyzed it—extracting key details such as NDA clauses, dates, and obligations—and delivered structured insights within seconds.

‍

For Model Training and Quality

We conducted multiple fine-tuning iterations and testing cycles to achieve consistent, high-quality results across various document types.

For Document Type Differentiation

The LLM was guided by a custom decision tree that mapped document categories to tailored prompt templates, ensuring contextual accuracy for every analysis.

For Speed Optimization

Our engineers refined the prompt flow and decision tree architecture, enabling real-time document analysis without performance lag.

THE RESULT

Achieving 70% Faster Document Analysis and 90% Greater Accuracy Through LLM-Driven Automation

The implementation of the LLM-based analysis engine significantly improved the speed and consistency of document processing within the client’s SaaS platform. By automating contract review workflows and optimizing the decision tree logic, the client achieved measurable efficiency gains and higher end-user satisfaction.

Key Outcomes:

Document analysis speed increased by up to 70%, reducing review time from several minutes to seconds per file.
Accuracy and consistency improved by over 90%, minimizing human error and ensuring reliable insights across document types.
Scalability enhanced — the system now supports batch analysis of large document sets without performance degradation.
Seamless integration with the client’s SaaS product, enabling automated analysis immediately after document upload.

Overall, the solution empowered the client to process more client requests in less time, strengthening the product’s value proposition and positioning it as a next-generation platform for intelligent document analysis.

The Way We Deal with Your Task and Help Achieve Results

Step 1 of 5

Web development discovery

It's a good time to get info about each other, share values, and discuss your project in detail. We will advise you on a solution and help you understand if we are a perfect match for you.

Step 2 of 5

Discovering And Feasibility Analysis

One of our core values is flexibility. Hence, we work with either one-page high-level requirements or a whole pack of tech docs. In AI demand forecasting case studies, there are numerous models and approaches, so at this stage, we perform a set of interviews to define project objectives. We elaborate and discuss a set of hypotheses and assumptions. We create a solution architecture, a project plan, and a list of insights or features to achieve.

Step 3 of 5

Solution Development

The work starts with data gathering, data cleaning, and analysis. Feature engineering helps to determine your target variable and build several models for the initial review. Further modeling requires validating results and selecting models for further development. Ultimately, we interpret the results. Nevertheless, demand forecasting solution modeling is a process requiring many back-and-forth iterations. We are result-focused, as it's also one of our core values.

Step 4 of 5

Solution Delivery

AI demand forecasting solutions can be a list of insights or models that consume data and return results. Though we have over 15 years of expertise in data engineering, we expect the client's participation in the project. While modeling, we provide midterm results so you can always see where we are and provide us with feedback. By the way, a high level of communication is also our core value.

Step 5 of 5

Support And Continuous Improvement

We understand how crucial the solutions that we code for our clients are! We aim to build long-term relations, providing guarantees and supporting agreements. Moreover, we are always happy to assist with further developments, and statistics show that 97% of our clients return to us with new projects.
