Payment Infrastructure Upgrade for Energy Australia.
PCI DSS Bpoint upgrade across four digital touchpoints. Phased. Fixed cost. In production.
01/ the brief
Compliance risk. Fragmented payment journeys. Growing technical debt across four platforms.
EnergyAustralia serves millions of Australian energy customers across MyAccount, their mobile app, checkout, and direct debit — each requiring a consistent, compliant payment experience. Their legacy Bpoint payment flows risked falling behind PCI DSS standards, and inconsistency across touchpoints was creating both regulatory exposure and poor customer experience.
- Legacy payment flows risked non-compliance with evolving PCI DSS standards
- Payment experiences across MyAccount, checkout, and mobile were inconsistent and outdated
- Manual interventions and lack of standardisation slowed enhancements and introduced complexity
- Increasing transaction volumes demanded a more robust, secure payments foundation
02/ the solution
Four tranches. Every touchpoint. Full PCI DSS alignment — without disrupting live services.
Crystal Delta delivered a structured four-tranche PCI DSS Bpoint upgrade — standardising payment flows, modernising each touchpoint, and future-proofing the infrastructure across all digital platforms.
What's under the hood
- Tranche 1: Secure, streamlined click-to-pay functionality with full PCI DSS alignment
- Tranche 2: Consistent payment flows across MyAccount web and mobile app
- Tranche 3: Modernised checkout experience with secure card storage and management
- Tranche 4: Secure and user-friendly direct debit management within MyAccount
- Fixed-cost, phased delivery with a dedicated team of developers, QA, and DevOps alongside EA's Digital Engineering team
