Traditional financial management tools struggle to personalize categorization at scale, often locking users into rigid category structures. NeenOpal, leveraging AWS and OpenAI, built a FinTech SaaS platform that integrates seamlessly with services like Plaid, Stripe, and Bill.com to automate income and expense categorization. By using lightweight LLMs, we enabled user-defined financial categories with real-time AI-powered classification, creating a personalized, scalable, and cost-efficient solution.
Despite leveraging multiple FinTech tools, businesses faced persistent obstacles in achieving accurate and personalized financial categorization. Traditional approaches lacked flexibility, were costly to maintain, and failed to unify fragmented financial data.
Predefined static categories failed to capture diverse user needs across geographies.
Users couldn’t define their own categories, limiting flexibility in financial planning.
Changing categories required ML model retraining, making the process costly and time-consuming.
Financial data came from multiple APIs, Plaid, Stripe, Bill.com, etc., in inconsistent formats.
Large language models were overkill, while traditional models lacked flexibility.
NeenOpal built an AI-powered financial SaaS platform on AWS, integrating lightweight OpenAI models to classify transactions dynamically. Users could define their own expense categories, and the system would auto-classify based on natural language descriptions from transaction metadata.
Each user submits their own categories, e.g., “Dining Out,” “Groceries,” “Treats”, which are used for real-time classification using GPT-based APIs.
The solution integrates Plaid, Bill.com, Stripe, and more, normalizing data across different platforms.
Instead of heavy ML pipelines, OpenAI’s low-cost models classify transactions contextually, cutting infrastructure and retraining costs.
Built using AWS Lambda, S3, API Gateway, and RDS, the solution is serverless and scales with usage, optimizing cost and performance.
