Quality is productivity
Improve quality
before it becomes rework.
Audit teams lose hours to preventable rework — missing documentation, unclear conclusions, inconsistent workpapers, late-stage review surprises. The earlier an issue is caught, the cheaper it is to fix.
Tellen moves quality to the start of the audit — so teams move faster with more confidence.
The later a quality issue surfaces, the more effort it takes to clear. Tellen catches issues in the workpaper — before review, not at inspection.
Catch missing documentation and unclear conclusions early, before they become hours of redo.
Cleaner workpapers and complete binders move through manager and partner review faster.
Guidance and standards research applied in the moment, so the support is right the first time.
Issues are surfaced and resolved before the reviewer ever opens the file.
Engagement-level scans flag gaps and inconsistencies ahead of quality and inspection review.
Faster engagement wrap-up and more capacity for the judgment work that matters.
Methodology enforced where work happens
In the workpaper. Across the binder. Across the firm.
One platform, three layers of audit quality — right in Excel and Word, at the binder level, and firm-wide. Your methodology, enforced at every level.
More than a checklist — a custom quality companion.
Not a static checklist. Our forward-deployed engineers build a series of custom agents for your firm, so regardless of who's doing the work, it gets done correctly. Last year's engagement and this year's, your methodology, the standards and interpretations — all right there in Excel and Word, as a quality gate and first line of defense for the staff and seniors doing the work.
Review the engagement before the reviewer does.
QualityScan AI scans audit binders for completeness, consistency, and methodology issues before manager, partner, quality, or inspection review. Fewer late-stage surprises and faster review cycles.
Modern quality management for audit firms.
Manage quality objectives, risks, responses, monitoring, findings, remediation, and annual evaluations in one system — without disconnected spreadsheets and documents. Turn quality management into operational improvement.
Built as a platform
More than agents. An AI platform for audit.
Tellen turns your firm's unstructured work into structure — then executes against it consistently. A structured, quality-first approach to agentic automation in audit.
Tellen plugs into your binder and turns the full engagement record — PBC data, workpapers, financial statements — into structured insight, then grounds its agents in the standards, your methodology, and the engagement itself. Context-aware feedback, not generic AI.
Agents execute audit work the same way every time — enforcing your firm's methodology instead of improvising — so quality is repeatable across every engagement.
Your pricing aligns to the outcomes your firm achieves — higher quality and less rework — not the tokens you burn.
