Frequently asked questions about tax

How does RobotX ensure human oversight in AI processes?

RobotX is built on a human-in-the-loop philosophy: AI prepares; auditors approve.
 Every automated output is transparent, reviewable, and editable with visible links to underlying evidence.
 This ensures that professional judgment, not automation, drives every audit conclusion.

What is the typical time savings or ROI for firms?

Actual time savings vary by engagement and depend on factors such as the reliability of client IT systems, the audit approach, hard-close requirements, and the complexity and materiality of the entity.
On average, firms report savings of around 170 hours on a 400-hour audit.
Engagement teams experience faster preparation, standardized and review-ready outputs, and shorter review cycles.
By redeploying just a quarter of those saved hours, most firms achieve an ROI exceeding five times within the first year.

How is RobotX different from traditional audit software?

RobotX is not a reporting or analytics add-on. It’s an AI-native audit execution platform.
Where other tools visualize data, or create snippets into excel, leading to bulky working papers.
RobotX automates the actual work: Tests of Details, reconciliations, and evidence linking without bulky excel files.
Everything happens inside Excel, so adoption is smooth and workflows remain familiar.

How is client data protected?

RobotX is ISO/IEC 27001:2022 and SOC 2 Type I certified and designed for full data protection.
 All information is encrypted using AES-256 at rest and TLS 1.3 in transit.
 Hosting takes place in the EU (Azure West Europe NL with geo-redundant backup in North Europe IE), with SSO and MFA authentication by default.

Does RobotX meet ISA 230 documentation requirements?

Yes. RobotX produces standardized, traceable working papers that align with ISA 230 and firm methodology requirements.
Every figure and conclusion is linked to its source evidence, providing a transparent audit trail and review-ready documentation directly in Excel.
