Trust & governance

Trust is created by traceable decisions.

TTL makes visible which data was used, which rule was applied, where a review was required, and who approved a result. Automation stays controlled and documented.

Development

Co-developed with the experience of leading audit and tax advisory firms.

TTL was developed together with experts from leading audit and tax advisory firms. The platform translates that experience into structured data models, rule packs, review steps, and result standards.

PRINZIP 01
Rule reference

Every automated decision references an approved rule and its validity period.

PRINZIP 02
Evidence

Source transaction, document, master data, and calculation stay linked to the result.

PRINZIP 03
Review

Special cases are escalated based on defined thresholds, conflicts, or missing data.

PRINZIP 04
Accountability

Approval, override, and correction are assigned to a role or person and historised.

Audit trail

Eight questions every result can answer.

The trail is not a log file. It is the derivation of the result — readable for the person who has to approve it.

What we claim — and what we do not

Auditable, traceable, rule-based, documented.

These four terms describe what TTL demonstrably delivers. Claims such as “legally certain”, “tax-office-proof”, “error-free”, or “fully automatic” are not made on this website. Reporting obligations, thresholds, and tax classification remain case-dependent; specialist responsibility stays clearly assigned.
