with XBRL conversions handled for you.
The ARKK regulatory reporting portal keeps your CBI filings aligned with the latest reporting requirements, building taxonomy updates, regulatory changes, and validations into the background. It's cloud-based, so there are no system updates or software downloads needed on your end.
This matters because financial services companies still relying on manual processes or spreadsheets face avoidable risk. Keeping pace with evolving CBI reporting requirements is time-consuming, prone to error, and leaves teams exposed to non-compliance.
How ARKK simplifies CBI reporting
The ARKK portal aggregates your regulatory data, runs it through embedded validation logic, and produces recognised, submission-ready returns with a full audit trail. Our team gives you clear visibility across every module and reporting cycle, so nothing gets missed ahead of a deadline.

+ What is CBI reporting?
CBI reporting refers to the periodic regulatory returns that entities regulated by the Central Bank of Ireland, including investment funds, fund service providers, and financial institutions, must submit in XBRL format via the CBI's Online Reporting System. It supports the Central Bank's oversight of financial stability, investor protection, and market conduct across the sector.
+ How does ARKK support CBI compliance?
ARKK's regulatory reporting portal gathers your data through excel-based templates, runs it through embedded validation logic aligned to the CBI's schema, and produces a submission-ready XBRL return with a full audit trail. Our team keeps taxonomy and regulatory updates built into the portal, so your return stays aligned with current requirements.
+ How long does it take to implement a CBI reporting solution?
Implementation time depends on the number of returns you're required to file and the complexity of your existing data setup. Most clients are operational well ahead of their next filing window, with our team providing hands-on support throughout onboarding.
+ Does ARKK integrate with existing data systems?
Yes, ARKK's Excel-based templates link to your existing workbooks, so you can populate reports using data you already hold rather than re-entering it into a new system.
+ How is data secured on the ARKK platform?
ARKK's portal is ISO 27001 certified, the internationally recognised standard for information security management, giving you a single, secure destination for uploading, tracking, and accessing your CBI submissions.
+ What are the risks of managing CBI reporting manually?
Manual reporting is time-consuming and prone to error, particularly across multiple modules and reporting frequencies. Spreadsheet-based processes increase the risk of miscalculations, missed validations and rejected returns, leaving teams exposed to non-compliance as requirements evolve.
