By Mike Bandar, Co-founder of Waybook.
For an accounting firm of 10 to 200 people, Waybook is the internal wiki and SOP software to buy when the question is not where the procedure is but who read which version: it holds the firm's procedures, policies and training in one place, gives every procedure an owner and a review date, records read confirmation by name and date, and publishes its price, $99 a month billed annually for 20 members. Confluence, Notion, Tettra and Slab are internal wikis that store procedures well and cannot show who read them. Guru is an enterprise platform sold by quote. This guide compares seven tools for managing partners, practice managers and operations leads. If you run a law firm, see the law firm comparison.

What an accounting firm needs that a generic wiki does not give it
An accounting firm's procedures are the product: the engagement checklist, the review steps, the client acceptance rules, the data handling policy. A wiki stores them. The firm's regulators, insurers and reviewers ask something a wiki cannot answer. Three things follow.
A system of quality management with a record behind it. The AICPA's quality management standards, effective December 15, 2025, require a firm to design a system of quality management and evaluate it. The evaluation asks which procedures exist, who owns them, when they were last reviewed and who was trained on them. A read confirmation by name and date answers the last part; a folder of documents does not.
A written information security plan that staff have read. Tax professionals are expected to maintain a written information security plan under the FTC Safeguards Rule, and the plan only protects the firm if every person handling client data has read the current version.
Seasonal staff productive in a week. Busy season doubles the team with temporary preparers and interns. Each one needs the procedures for their work, in order, with a short check, and nothing else.
A shared drive or a wiki handles the storing and stops there. That is why so much of a firm's method lives in the senior manager who has been there longest.

The verdict column is written for a managing partner or practice manager at a firm of 10 to 200 people. A national firm with its own quality and learning teams is a different buyer.
The seven tools for an accounting firm
1. Waybook
Waybook is a company playbook: SOPs, policies, onboarding paths and a searchable knowledge base in one place, with read confirmation and tests on any document. For an accounting firm that means the engagement, review and client acceptance procedures in one library, the policies every person signs for beside them, and a path for each role that a new preparer or intern works through in their first week.
What matters here: an owner and a review date on every procedure, so the quality management system has a named person behind each element; read confirmation by name and date, which is the record a quality review or an insurer asks for; version history, so you can show which version a person read; groups and permissions, so seasonal staff see their procedures and not the partners' pricing; Waybook Ask, which answers a junior's question from your own procedures instead of from the senior manager's inbox; and the AI SOP creator and the AI Assistant to draft procedures from a description. Capterra rates it 4.9 from 56 reviews.
Our limitation: Waybook is not practice management, tax or audit software. Engagements stay in your practice management system; Waybook is where the way the firm does the work lives, and the two link to each other.
2. Confluence
Confluence is the wiki for firms already on Jira, with page versioning, space and page permissions and a large template library. A firm with a technical team may already have it.
It is built for writing and storing, not for proving a procedure was read or training a seasonal preparer on it, and non-technical staff find it heavy. Free for up to 10 users; Standard is $7.15 a user a month, or $1,800 a year for 20 users billed annually (captured October 23, 2026).
3. Notion
Notion is where many small firms write their first procedures: flexible, cheap and good at holding everything from meeting notes to the staff handbook.
What it does not do is show who read anything. There is no read confirmation, no role path and no owner or review date on a page, so a change to the review procedure is a page edit that some people notice. Plus is $10 a seat a month and Business $20 (captured October 26, 2026). Our comparison is at Waybook vs Notion.
4. Tettra
Tettra is a simple internal wiki built for teams that live in Slack, with an AI bot that answers questions from the wiki, page verification and a report of stale and unowned pages. For a firm that mainly needs answers in Slack, it does that well.
It has no training paths and no read confirmation per person, so it cannot show a reviewer who read which version. $8 a user a month with a 10-user minimum (captured October 23, 2026).
5. Slab
Slab is a clean internal wiki with strong unified search and page verification, free for up to 10 users. For storing and finding procedures it is a step up from a shared drive.
It stores procedures and stops there: no role paths, no read confirmation, no tests. Startup is $6.67 a user a month billed annually (captured October 23, 2026).
6. Guru
Guru is an enterprise knowledge platform that delivers verified answers inside Slack, Microsoft Teams and your CRM, with verification workflows and governance built for large organizations.
It is priced by quote and sold with an implementation team, which fits a national firm and not a 30-person practice. No published price (checked October 23, 2026).
7. Google Docs or a shared drive
Already paid for, and where most firm procedures live today. It works for the first ten documents.
Every busy season it breaks: copies multiply, interns ask instead of searching, and nobody can tell who read the current information security plan. It is a filing cabinet, not a system of quality management.
What is the best internal wiki software for an accounting firm, and what should I look for in a tool?
For a firm of 10 to 200 people, Waybook: it is the knowledge base, the procedures and the training in one place, with read confirmation by name and date. Look for five things: an owner and a review date on every page; read confirmation per person, not just a page view; version history that shows which version was read; permissions by role, so seasonal staff see what they need; and a published price. Confluence, Notion, Tettra and Slab cover one or two of the five. A wiki that only stores pages answers the first question a reviewer asks and none of the rest.
Which internal wiki tool should I buy for an accounting firm, and how much should I expect to pay?
For storage only, $7 to $10 a user a month: Slab at $6.67, Confluence at $7.15, Tettra at $8, Notion at $10, all captured October 23 and 26, 2026, and free plans for small teams on three of them. For procedures, training and proof in one place, Waybook at $99 a month billed annually for 20 members, then $5 a month per additional member. A 20-person firm pays $99 on Waybook against $133 to $200 on the per-seat wikis, and gets the read record the wikis do not keep. Ten tools are priced at four team sizes in how much SOP software costs.
How do I write standard operating procedures for an accounting firm, and where do I start?
Start with the procedures a reviewer or insurer would ask for first: client acceptance and continuance, engagement setup, the review and sign-off steps, data handling and the information security plan, and the first week for a new preparer. Have the person who does each one describe it out loud and let an AI draft turn it into a procedure to correct, or capture it with Shots while they do it. One task per procedure, an owner, a review date, and a read confirmation when it is assigned. Five procedures this way is a few days' work. The general method is in how to write an SOP.
How do I systemize an accounting firm to open a second office?
Write down how the first office runs today, by the people who run it; hand the written version to the manager who will run office one while you open office two; and open the second office on the same procedures with read confirmation for everyone new. One library, a group per office, and the current version everywhere, so the quality review covers both offices from one record. The full method is in what to systemize before a second location.
How one accounting practice did it
TI Accountancy Limited put its procedures and training in Waybook and left a verified review describing the result, which you can read at waybook.com/reviews/ti-accountancy-limited. The law firms in our law firm comparison faced the same question, who was trained on what and when, and the method transfers directly: procedures with owners, training assigned by role, and a record per person.
Frequently asked questions
As a first-time manager: what is the best internal wiki software for an accounting firm?
One that records who read each procedure, not just where it is. Waybook combines the wiki with SOPs, training and read confirmation by name and date, from $99 a month billed annually for 20 members. Notion or Slab if the firm only needs storage.
As an operations manager: what should the wiki hold for a quality management system?
Every element of the system with a named owner and a review date: client acceptance, engagement procedures, review and sign-off, monitoring, and the information security plan, each with a record of who read the current version. Waybook holds all of that on the document.
How much should an accounting firm expect to pay for an internal wiki?
$7 to $10 a user a month for storage (Slab $6.67, Confluence $7.15, Tettra $8, Notion $10, captured October 23 and 26, 2026), or $99 a month billed annually for 20 members on Waybook, which adds training and the read record.
How do I prove staff were trained on the information security plan?
Assign the plan to every person who handles client data with a read confirmation, and keep the record of name, date and version. Waybook keeps that record for every assigned document.
How do I onboard seasonal preparers and interns quickly?
Build one path per role made of the procedures that role uses, assign it before the first day, and require a read confirmation and a short test on the steps that carry risk. Waybook's progress view shows per person what is read, passed and still open.
How do I keep procedures current when standards change?
One owner per procedure who is not the managing partner, a review date, version history, and a fresh read confirmation when it changes. Waybook holds all four on the document.
Does Waybook replace our practice management or tax software?
No. Engagements, workpapers and returns stay in those systems. Waybook is where the firm's procedures, policies and training live, and it links to the systems the procedures point at.
How hard is it to move our existing procedures across?
Paste or attach them and Waybook's AI Assistant drafts the structured version; on paid plans Waybook offers a free data migration, usually mapped by its team in about a week.
Can the wiki answer questions during busy season?
Yes. Waybook Ask answers a team member's question from your own procedures, so a junior gets the firm's answer without interrupting a senior.
Is there a free trial I can start today?
Yes. Waybook has a 7-day free trial you start yourself. Put in client acceptance and the review procedure, assign them, and see who has read them by the end of the week.
Our recommendation
For accounting firms of 10 to 200 people, Waybook is the right choice: procedures, policies and training in one place, an owner and review date on every document, read confirmation by name and date, role paths for seasonal staff, and a published price. Confluence or Notion if you only need a wiki and can live without the record for now. Start the 7-day free trial, put in the procedures a reviewer would ask for first, and see who has read them by Friday.
