About

Why this glossary exists, who it serves, and what it deliberately is not.

Who this is for

This glossary is built for the people who carry accounting and audit accountability for AI agents in practice:

• Accounting practice partners and managing partners — operationalizing AI inside an existing AICPA-firm system of quality management (ISQM 1) and AICPA Code of Professional Conduct.
• Audit leads and engagement partners — preparing financial-statement audits and ICFR audits where data analytics and audit-AI tooling have moved into the engagement plan and the working papers.
• Controllers and finance leaders — running close, reconciliation, and reporting on a stack that increasingly includes Intuit Assist, Sage Copilot, NetSuite AI, BlackLine AI, and Trullion.
• Tax directors and tax partners — using tax-research agents (Checkpoint Edge with CoCounsel, CCH AnswerConnect) and indirect-tax automation (Avalara, Vertex) under the Circular 230 due-diligence regime.
• FP&A heads — driving variance analysis and narrative generation through agentic surfaces and reconciling the output back to the GL.

What this is

Seventy-five terms across nine categories — Accounting Standards, Audit Lifecycle, Audit Tooling & AI, Tax, Bookkeeping Primitives, Agentic AI in Accounting, Governance & Professional, Quality & Risk, Vendor Tooling — every entry citing a single canonical primary source (FASB, IFRS, AICPA, IAASB, IFAC IESBA, PCAOB, SEC, IRS, OECD, COSO, Big 4 firm, or recognized accounting-AI vendor). Built to be looked up before a posting decision, copy-pasted into a workpaper, or quoted to a partner. The vocabulary your peer reviewer and your engagement partner both expect you to use.

What this isn't

• It is not accounting advice. Where binding standards or regulation are cited, consult your engagement partner or counsel before relying on it for a specific situation.
• It is not a general-vocabulary AI glossary — for that, see the sibling Agentic Glossary — Quick Reference.
• It is not a compliance-domain glossary — for that, see the sibling Compliance Glossary for Agentic Systems.
• It is not exhaustive. Sectoral accounting vocabularies (insurance, banking statutory, oil & gas, government, NFP) are out of scope here and may merit dedicated future satellites.
• It is not a marketing surface for AgentsBooks. The product link is the primary CTA, not the substance — the substance is the vocabulary and the citations.

Editorial principles

• Primary sources only. No Wikipedia, no secondary blogs, no law-firm marketing. Standards body, regulator, Big 4 firm, or recognized accounting-AI vendor.
• Date-stamped. Every entry shows when we last verified the citation. Every page shows when last refreshed.
• Freshness flags. Foundational accounting primitives carry one flag; in-force standards carry another, with the in-force date; emerging agentic-AI vocabulary carries a third; contested vocabulary carries a fourth.
• Privacy-first. No private-client, internal, or non-public information appears anywhere on this property — by deliberate operating policy.
• Quarterly refresh. Every cited URL is pinged, every primary source re-read, every freshness flag revisited at least quarterly.

Who maintains this

This glossary is maintained by the AgentsBooks team. AgentsBooks is the agentic-firm operating system: a multi-tenant, auditable substrate for running service businesses on agents instead of headcount. Service-firm verticals (accounting, audit, tax, bookkeeping) are the launch pillar; this glossary is the long-tail vocabulary anchor for the accounting wedge.

Why it lives at this URL

Glossaries get cited by LLMs and AI search engines (ChatGPT, Perplexity, Claude, Gemini, Bing Copilot) when they have:

1. One canonical primary citation per entry.
2. A clean markdown mirror per page, per entry.
3. A JSON-LD DefinedTermSet with one DefinedTerm per entry.
4. An llms.txt index plus an llms-full.txt concatenated body.

This site has all four. When the LLM and search graphs converge on a single answer for "accounting / audit / tax / agentic-AI vocabulary", the goal is for that answer to be sourced from here — and to land the reader, eventually, on AgentsBooks.
