Project overview

A leading power and utility company needed a more efficient way to run credit checks during contract creation. The existing manual process was costly, error-prone and slowed liquidity.

Challenges

  • Complex manual processing increased time and errors
  • High operational overhead from labor-intensive credit checks
  • Scalability issues as the customer base grew
  • Need for reliable third-party integration and transparent process visibility

Our approach

We built an automated, API-based event system integrated with the contract management platform, using API Gateway, Lambda and SQS for reliable async processing.

Event-driven flow

  • Contract creation triggers an API call to initiate the credit check
  • SQS queues manage event traffic and async handling
  • Lambda functions process business logic for each event
  • Reliable forwarding of requests to third-party credit check providers
  • Automatic approve / reject / manual-review decisioning based on results
  • End-to-end monitoring for transparency and accuracy

Outcomes

  • 70% reduction in manual credit-check handling
  • 90% reduction in credit-check errors
  • Decisions completed within minutes
  • Architecture scaled with the customer base without added effort
