In 1494, Luca Pacioli published Summa de arithmetica, establishing the principles of double-entry bookkeeping that still govern the profession today. Paciolus is built on the same foundation Pacioli laid — rigor, precision, and respect for professional judgment.

Why We Built Paciolus

Audit work demands precision, professional skepticism, and thorough documentation. The tools that support this work should reflect the same rigor. Paciolus was designed to meet that standard — purpose-built for substantive analytical procedures, not adapted from general-purpose analytics.

“The moment when you need a defensible answer shouldn’t depend on the size of your firm. We built Paciolus so it doesn’t.”

What Paciolus Is — and What It Is Not

What Paciolus Is

  • An analytical tool designed for substantive audit procedures
  • A tool that surfaces analytical exceptions requiring professional evaluation
  • A workpaper-ready export system (PDF, Excel, CSV)
  • Built on Zero-Storage architecture to preserve client confidentiality

What Paciolus Is NOT

  • Not an audit software that replaces professional judgment
  • Not a system that provides assurance opinions
  • Not a tool that generates audit evidence
  • Not a platform that stores your financial data

Zero-Storage Commitment

Paciolus processes all financial data entirely in-memory. Nothing is written to disk, stored in a database, or retained after your session ends. There is no persistent raw financial data to breach, subpoena, or expose — which simplifies your GDPR and CCPA posture to its most defensible form: zero retention.

Built for Financial Professionals

Built with ISA and PCAOB Standards in Mind

Every workflow reflects how audit teams document substantive analytical procedures.

Professional Standards

Every test battery references applicable professional standards. Memos cite ISA 240, ISA 500, PCAOB AS 2401, and more.

Workpaper Ready

PDF memos with signoff lines, Excel exports with full underlying data, and CSV output for downstream analysis.

How Paciolus Is Different

No Installation Required

Access from any device without desktop software or plugins. Open a browser, upload a file, get documented results.

Zero-Storage by Architecture

Client financial data never touches a database. All processing occurs in-memory and is destroyed on session completion, preserving confidentiality by design.

Standards-Cited Memos

Every PDF memo cites the governing ISA, PCAOB, IFRS, or ASC standard. Ready to file directly into your working papers.

Immediate Results

Upload to documented analysis — typically under three seconds for files up to 10,000 rows in a standard cloud environment. No batch queuing, no overnight processing.

Where Paciolus Fits in Your Workflow

Paciolus is a standalone analytics platform that complements your existing tools. It accepts 10 file formats including QuickBooks exports (QBO, IIF), bank feeds (OFX), Excel, CSV, TSV, TXT, PDF tables, and ODS spreadsheets.

Export results as PDF memos, Excel workpapers, or CSV files and import them directly into your working paper system — whether that's CaseWare, TeamMate, or a firm-internal structure.

Every tool run is logged in your activity history with timestamps, so you have a documented record of which analyses were performed, when, and for which client. This log is visible in your workspace and included in the diagnostic package export.

Seven-day trial. All twelve tools. Your client's raw files are never stored.
