ContractCube: The AI-driven system that identified $3.5m of revenue leakage across 4 regions

How ContractCube identified billing discrepancies for a Global Airport Services Operator.

The challenge

A leading global airport services operator faced significant revenue leakage due to underbilling for services rendered. This issue was driven by:

• Inaccurate service capture information, leading to missed billing opportunities.
• Complex contractual billing logics, which were inconsistently implemented.
• Manual revenue recovery processes, which were inefficient, non-exhaustive, and lacked scalability.

To address these challenges, QuantSpark deployed ContractCube, an AI-driven solution that could automate revenue recovery and identify billing discrepancies across operations in the US, Canada, UK, and Ireland.

The solution

ContractCube is an advanced AI-powered system designed to extract, match, and analyse service and billing data with unmatched accuracy.

1. Document Extraction

• Leveraged multi-modal Large Language Models (LLMs) to extract key details—such as pricing, clauses, and conditions—from contractual documents.
• Enabled automated processing of scanned PDFs, eliminating manual data entry errors and inefficiencies.

2. Service Capture Matching

• Applied natural language processing (NLP) techniques to dynamically map service records to contractual information.
• Ensured that every service provided had an accurately matched contractual counterpart for seamless billing validation.

3. Discrepancy and Revenue Leakage Identification

• Compared generated invoices against historical issued invoices to pinpoint billing discrepancies.
• Categorised discrepancies based on root causes, such as agreed price changes or billing logic inaccuracies.
• Provided actionable insights to trigger and support financial and commercial auditing investigations.

The results

By implementing ContractCube, the airport services operator achieved:

• Automated and scalable revenue recovery, reducing reliance on manual intervention.
• Enhanced billing accuracy, minimising future revenue leakage and boosting financial integrity.
• Increased auditing efficiency, enabling swift identification and rectification of underbilling issues.

With a data-driven, AI-powered approach, ContractCube empowered the operator to recover lost revenue, optimise billing processes, and improve financial oversight—creating a long-term, scalable solution for revenue assurance.
