Frequently asked questions
The Diagnostic Auditor automatically checks the accuracy and completeness of your transaction reports using a comprehensive, field-by-field rules engine. Every report is assessed against an extensive matrix of regulatory validations, data dependencies, and logic checks — far beyond basic schema or regulator-level validation.
It can be used before submission (to catch issues early) and after submission (to independently verify what was accepted by the regulator), giving you clear visibility of data quality and potential compliance risk.
Yes. One of the key strengths of Qomply’s QA tools is their ability to identify silent errors that is, issues that pass regulatory validation but are still incorrect, inconsistent, or mis-reported.
These include problems such as incorrect reference data, mis-applied logic, internal inconsistencies between fields, or values that are technically valid but wrong in context. These errors often go undetected until a regulatory review or investigation. Diagnostic Auditor helps surface them proactively.
Qomply improves data quality by combining deep regulatory logic, cross-field validation, and independent assurance of submitted reports. Instead of relying solely on ARM feedback or regulator rejections, firms gain their own transparent view of reporting accuracy.
This reduces remediation effort, strengthens governance, and enhances internal audit controls — helping firms manage regulatory risk more effectively.
Validation and reconciliation are performed at speed and at scale, with results available shortly after data is submitted for checking. Large datasets can be processed efficiently without sampling, allowing firms to review 100% of their reports, not just a subset.
This enables near-real-time insight into data quality and faster resolution of issues before they escalate.
Yes. Qomply works alongside your existing reporting setup. Whether you submit via an ARM, third-party vendor, or directly to the FCA, Diagnostic Auditor provides an independent layer of quality assurance.
It does not replace your submission channel as it strengthens it by validating and reconciling what you send and what the regulator receives.
No specialist technical expertise is required. Diagnostic Auditor is designed for compliance, operations, and reporting teams, with clear dashboards, plain-English issue descriptions, and actionable outputs.
For firms that want deeper integration or automation, APIs are available. Day-to-day use does not depend on technical resources.
