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.
