Across the firm

One research standard for every team

Bigger firms don't have one research problem. They have several, and the standard of the answer has to hold across all of them.

Tax compliance

Staff and seniors

Senior-level research on multi-state nexus, Section 199A and entity questions, with a trail the reviewer can check instead of redo.

Advisory and M&A

Transaction teams

Structuring, elections and due diligence across federal, state and cross-border rules. Deep Research handles the multi-issue questions.

Audit and assurance

Engagement teams

Audit Research cites the exact standard, from FASB ASC and PCAOB to GASB, the Yellow Book and Uniform Guidance.

International

Cross-border specialists

GILTI, FDII, Subpart F, treaties, OECD Pillar Two and EU VAT, with the US rules and the foreign rules side by side.

Review

Managers and partners

View Steps shows which sources were used and how they lead to the conclusion, so review time goes into judgment, not checking citations.

Firm leadership

Innovation and IT

A tool you can govern: per-user plans, a firm AI policy template, and access through the web app, Claude, ChatGPT or the API.

Why firms choose Bizora

Built for work that gets reviewed

Defensible

Every answer is cited

Answers come from a curated database of primary authority: the IRC, Treasury Regulations, IRS rulings, case law and state codes. No summaries of summaries, and nothing a reviewer has to take on faith.

Reviewable

The reasoning is on the record

View Steps records how each conclusion was reached. Keep it with the workpapers for internal review, quality control and Circular 230 documentation.

Connected

Research, files and memos in one place

Upload returns and K-1s to the Vault, ask across the whole project, then draft the memo or client email in Canvas with the citations carried over.

Flexible

Where your teams already work

Use Bizora in its web app, as an approved connector in Claude, as an app in ChatGPT, or built into your own tools through the API and MCP server.

Rolling it out

  4. STEP 4

In practice

Trusted by firms of every size

Bizora is used by firms of more than 50 CPAs, including a major Pacific Northwest firm that uses it for middle-market transactions.

Rolling out Bizora

What is the best AI tax research tool for mid-size and large CPA firms?

Firms of that size need research that a reviewer can check, works across tax and audit, and fits how teams already work. Bizora gives every answer a citation to primary authority and a View Steps reasoning trail, covers federal, all 50 states and international questions, includes Audit Research on Pro and Pinnacle, and runs in its own web app and inside Claude and ChatGPT.

Can we roll Bizora out across the whole firm?

Yes. Plans are billed per user, so you can start with one team or practice area and add seats as you go. The Pinnacle plan includes priority support, a dedicated channel, team training and personalized onboarding. For firm-wide or volume arrangements, contact admin@bizora.ai.

Do you help firms write an AI usage policy?

Yes. Bizora's free Firm AI Usage Guidelines give you a written framework covering how to classify AI use, which tool tiers suit client work, IRC §7216 consent and vendor governance questions. Review it with counsel, complete the firm-specific fields and circulate it to staff.

Quality and review

How do reviewers check an answer from Bizora?

Every answer cites the IRC section, regulation, ruling or case behind it, and View Steps shows which sources Bizora used and how they lead to the conclusion. Reviewers can trace each position to its source and keep the trail with the workpapers for internal review and Circular 230 documentation.

Does Bizora cover audit and assurance as well as tax?

Yes. Audit Research answers accounting and audit questions with citations to the exact standard, including FASB ASC, PCAOB, AICPA, GASB, the GAO Yellow Book and Uniform Guidance. It is included with the Pro and Pinnacle plans, on the same login as tax research.

Can we get credentialed review and sign-off?

Yes. The Bizora Advisory Group is a monthly review retainer in which a credentialed tax professional reviews returns, positions and memos before they go out and delivers cited findings under your firm's name.

Integrations and security

Does Bizora work inside Claude and ChatGPT?

Yes. Bizora is an approved connector in the Claude Connector Directory and an app in the ChatGPT App Directory, so firms already using those assistants get the same cited research inside them. The free Bizora Skills turn common workflows into ready-to-use Claude skills.

Can Bizora be built into our firm's own tools?

Yes. The OpenAI-compatible API and MCP server let firms embed Bizora's research and document analysis in internal tools and client-facing dashboards, including as a white-label solution. Most custom workflows are delivered within two to four weeks.

How does Bizora handle client data?

Client data is encrypted at rest and in transit, and Bizora's SOC 2 audit readiness is underway. See the security page for details on access controls and data handling.
