Consumer Data Right
The Hidden Cost of Building Your Own CDR Infrastructure
For banks, energy providers, and fintechs preparing for the Consumer Data Right (CDR), the build vs. buy decision is a major fork in the road. On paper, building your own CDR infrastructure sounds like a straightforward engineering task. You've got a capable internal team. You’ve built APIs before. Why not handle it in-house? But here's the truth: building your own data holder infrastructure is rarely as cost-effective, scalable, or future-proof as it seems. In this post, we’ll break down the real — and often hidden — costs of building CDR compliance internally, and why more institutions are choosing managed platforms like Fiskil instead.
1. Compliance is Not One-and-Done
CDR compliance is not a checklist you complete once. It’s an evolving set of obligations governed by the ACCC, the OAIC, and the Data Standards Body.
If you build your own solution, you’re committing to:
- Continuous monitoring of rule and standard changes
- Frequent updates to your API endpoints
- Managing version compatibility with the CDR Register
- Regular third-party assurance assessments
Each of these comes with ongoing engineering and legal costs. Compliance is now part of your product backlog — permanently.
2. Infrastructure is Just the Beginning
Standing up a compliant data holder platform requires more than just API development. You also need to manage:
- Consent flows and dashboards
- Dynamic Client Registration (DCR)
- Outage reporting to the CDR ecosystem
- Robust audit logging
- Uptime SLAs and performance monitoring
- CDR policy documentation and public-facing portals
These are critical requirements, not nice-to-haves — and building them in-house diverts time from your core product roadmap.
3. The Opportunity Cost is Real
Every day your engineers spend maintaining compliance is a day they’re not shipping customer-facing features or innovating in your core product.
For product-led companies, this is more than a resource issue — it’s a strategic cost.
Do you want to be known as the best at managing API specs and registry updates? Or as the best at delivering value to your customers?
4. You’re on the Hook for Risk
With in-house infrastructure, you carry all the operational risk:
- If the registry changes tomorrow, you need to update.
- If your consent flow breaks, you could be non-compliant.
- If your response times lag, users notice.
- If you get audited, you're accountable for every data point.
And with penalties for non-compliance, even a small slip can lead to serious reputational and financial impact.
5. The Cost of Keeping Up
Let’s say your MVP works fine today. What about tomorrow?
The CDR standards are still maturing. New data clusters are being introduced. Energy and non-bank sectors are being added. API specs are versioned and regularly updated.
Maintaining pace with this change isn’t just an engineering task — it’s a dedicated capability.
