The Internal Audit Pressure Point

Same Scope. Fewer Resources. Higher Standards.

Sampling Gaps Create Risk

SOX control testing relies on just 25–40 samples, leaving 99% of the population untested. Exceptions hide in the gap.

Fragmented Evidence

Source documents, ERP reports, third-party files, and spreadsheets live in different places and rarely tie out cleanly.

Manual, Repetitive Fieldwork

UARs, O2C audits, and recalculations consume IA capacity that should be focused on risk.

AI Without Guardrails

Generic AI can draft and summarize, but can’t carry the evidence trail that IA and SOX work require.

Agents, Automation & Intelligence in One Powerful Platform

Trullion is an auditable AI platform purpose-built for regulated accounting and audit workflows, not a generic LLM bolted onto a productivity tool. Every output is tied back to a source document, system record, or standard.

Agents

Instant answers, pattern detection, risk surfaced within audit guardrails

Not just AI. Auditable AI.

Domain-trained. Standards-aligned. Traceable to source. Human-reviewed before decisions are finalized. Miss any one of these and the output doesn’t clear the audit scrutiny bar.

Work Smarter Across Every Phase of the Internal Audit Cycle

100% population coverage

Replace sampling with full population testing. Stop letting exceptions hide in the untested 99%

Workpaper-native output

Results come out as the deliverable. No reformatting, no manual pasting. The work is the evidence.

Repeatable at scale

Build a test once, execute it continuously across quarters, entities, and fiscal years.

Strengthen the relationship between internal and external audit

External auditors increasingly expect population-level coverage, not just samples. When your IA work is powered by auditable AI, external auditors can rely on it rather than retest it. Trullion creates a documented, traceable evidence trail that holds up to external scrutiny and reduces friction at handoff.

Documented audit trail that external auditors can follow without re-deriving the work
Population-level testing that demonstrates coverage, not just sample compliance
Consistent methodology across control areas, quarters, and entities
