CORAA vs Traditional CAATs
IDEA, ACL Analytics, and CaseWare are powerful data analysis tools. But are rules-based CAATs still the best choice for Indian statutory audit?
Quick verdict
Choose CORAA if...
- • You need India-specific compliance out of the box (GST, TDS, NFRA)
- • You want AI-driven insights, not rules you have to write yourself
- • You want plug-and-play setup without weeks of training
- • You do statutory audit and need working paper generation
Choose CAATs if...
- • You need deep forensic data analytics on massive datasets
- • You are doing internal audit or fraud investigation
- • You have dedicated IT staff to write and maintain scripts
- • You need custom scripting for specialized analysis
The bottom line
Traditional CAATs like IDEA and ACL are excellent at what they do — deep, scriptable data analysis for forensic and internal audit. But they were not built for Indian statutory audit. CORAA is purpose-built for CA firms: AI-driven, India-compliant, and ready to use on day one without writing a single script.
