B2B SaaS operations
Best B2B SaaS knowledge management tools
For a small SaaS team that wants one wiki, Slite ($10 per member) or Slab (free up to 10 users) is enough; for answers that must stay correct, Guru is built around verification; for customer-facing articles, Help Scout Docs or Intercom sit next to the inbox; for a Microsoft 365 company, SharePoint is already licensed.
These thirteen products solve three different problems that all get called knowledge management: internal wikis, customer help centers and engineering Q&A. Decide which of the three you are buying before you compare prices, because a SharePoint seat bundled into Microsoft 365 and a Help Scout support seat are not substitutes. Prices below are from each vendor’s own pricing page, read on 7 October 2026; Guru, Document360, Bloomfire and the Stack Overflow for Teams Organization plan are quote-only. Confluence, Notion and Slab list plans, but their per-user dollar amounts did not appear in the page text we read, so for those three only plan limits are quoted.
| Tool | Best fit | Entry price on the vendor page |
|---|---|---|
| Guru | answers that expire unless someone re-verifies them | quote only |
| Confluence | long-form, structured documentation | Free plan, 10 users |
| Slite | a small team that wants one tidy wiki | $10/member/mo |
| Document360 | a public help center plus internal docs | quote only |
| Notion | a startup that wants docs, tasks and databases together | Free plan; paid per member |
| Slab | readable internal docs with a free tier | free up to 10 users |
| Tettra | answers delivered in Slack with owners attached | $8/user/mo, 10 user minimum |
| Help Scout Docs | a public help center next to a shared inbox | free for 5 users |
| Zendesk Guide | knowledge base inside a large support operation | $55/agent/mo on Suite Team |
| Intercom | help articles that hand over to a conversation | $85/seat/mo on Advanced |
| Bloomfire | a searchable knowledge community across departments | quote only |
| Stack Overflow for Teams | engineering questions with durable, searchable answers | Starter free trial; Enterprise by quote |
| Microsoft SharePoint | governed knowledge for a Microsoft 365 company | $7.00/user/mo in Business Basic |
Guru
Best for: answers that expire unless someone re-verifies them.
Guru is built around verification: its pricing page lists verification workflows and usage signals as part of the platform, and answers arrive as cited, permission-aware responses inside chat and the browser rather than in a wiki people have to visit. It is the strongest fit when the same operational questions come back every week and the real problem is that yesterday’s answer is wrong.
Guru describes itself as a platform and expertise offering, not just a per-seat tool: the pricing page says the investment is tailored to scale, knowledge complexity and AI maturity, and a package includes a knowledge and AI strategy team alongside the software. It lists 100+ integrations, including Slack, Teams, Salesforce, Zendesk, Confluence and SharePoint, and SOC 2 Type II. Nonprofits with 501(c)(3) status can ask about the Guru for Good reduced-cost program.
| Pros | Verification workflows and cited answers inside chat and browser |
|---|---|
| Cons | Quote-only; value depends on owners actually re-verifying cards |
| Pricing context | Pricing on request (quote-based): the pricing page describes a tailored package and lists no per-seat price. |

Confluence
Best for: long-form, structured documentation.
Confluence gives you spaces, page trees, templates and page history, and it connects to the rest of the Atlassian suite, so specs can sit beside Jira work. It is the natural wiki for engineering-heavy teams that already live in Jira.
The plan table gives concrete limits even where the price sits behind a selector: the Free plan covers 10 users, while Standard, Premium and Enterprise go up to 250,000 users. Automation allowances climb with the plan, from 50 automation steps per subscription per month on Free to 100, 250 and 500 steps per user per month on Standard, Premium and Enterprise. Whiteboards are capped at 3 per user on Free and 10 on Standard.
| Pros | Page hierarchy and history; Jira and Atlassian integrations |
|---|---|
| Cons | Structure drifts without a space owner; paid per-user amounts are on the vendor page |
| Pricing context | Free plan for up to 10 users; Standard, Premium and Enterprise scale to 250,000 users and are priced per user. Atlassian also offers a self-managed Data Center edition. |
| Official source | Vendor pricing page |
Slite
Best for: a small team that wants one tidy wiki.
Slite is a lightweight team wiki with a real-time collaborative editor, aimed at keeping decision notes, handbooks and onboarding documents in one searchable place. It is the pick for a company of 5 to 30 people that wants documentation without administering a platform.
The two plans are easy to cost: Basic is $10 per member per month and Pro is $20, so a 15-person team pays $150 on Basic and $300 on Pro. Look at Guru or SharePoint instead once you need answers re-verified on a schedule or permissions tied to a company directory.
| Pros | Clean editor; posted per-member prices |
|---|---|
| Cons | Stricter governance needs may outgrow a shared wiki |
| Pricing context | Basic $10 and Pro $20 per member per month. |
| Official source | Vendor pricing page |
Document360
Best for: a public help center plus internal docs.
Document360 is a dedicated knowledge-base product with versioning, categories and publishing controls, so it can run a customer help center and an internal wiki as separate workspaces. It fits when documentation is a product in its own right, with its own editors and reviewers.
Its pricing page sells a custom plan rather than a table, and says the quote is calibrated to six things: team accounts (editors and reviewers), workspaces, languages, SSO and security needs, the privacy model (public, private or mixed) and AI Premium Suite usage. It also says its team migrates existing content from Google Docs, Confluence, SharePoint, PDFs and other knowledge bases, and that standard migration is included in most quotes.
| Pros | Versioning, workspaces and languages; migration help in most quotes |
|---|---|
| Cons | Quote-only; more administration than a shared wiki |
| Pricing context | Pricing on request (quote-based): the pricing page has a quote form and no list prices. |
| Official source | Vendor pricing page |
Notion
Best for: a startup that wants docs, tasks and databases together.
Notion mixes documents with databases, forms and sites in one workspace, which makes it the usual choice for a young company that wants playbooks, specs, roadmaps and meeting notes in a single place instead of a wiki plus a tracker.
Its pricing page lists Free, Plus, Business and Enterprise plans, states that paid plans are charged per member, and says guests are free but can only open the pages they are invited to. A solo Free workspace has no block limit, while a multi-member Free workspace does. Its AI agents are free to try and then $10 per 1,000 monthly Notion credits, so AI use is a second meter on top of seats.
| Pros | Databases, forms and docs together; free guests |
|---|---|
| Cons | Search and structure degrade without an owner; AI credits are metered |
| Pricing context | Free, Plus, Business and Enterprise plans, charged per member on paid plans; Notion AI agents $10 per 1,000 monthly credits after a free trial. |
| Official source | Vendor pricing page |
Slab
Best for: readable internal docs with a free tier.
Slab is a focused internal knowledge hub: posts and topics, unified search, templates and a verification feature, without the database-and-tracker sprawl of a general workspace. It suits a team that wants a reading experience first and a flexible database second.
Its plan table is organized by limits. Free covers up to 10 users with 90 days of version history, Startup and Business have unlimited users with 365 days and unlimited history, and Enterprise starts at 100 users and goes through sales. Guests per user rise from 3 on Startup to 5 on Business and unlimited on Enterprise, a number to check if contractors or customers read your docs.
| Pros | Free plan; verification and unified search appear in the plan table |
|---|---|
| Cons | Free history window is 90 days; Enterprise needs at least 100 users |
| Pricing context | Free for up to 10 users; Startup and Business are paid plans with unlimited users; Enterprise (at least 100 users) is sold through sales. |
| Official source | Vendor pricing page |
Tettra
Best for: answers delivered in Slack with owners attached.
Tettra makes internal answers reachable where people already ask questions and assigns each page an owner, so a question asked in chat can be answered from a maintained page. Its pricing page leads with AI answers and AI page tagging on the Scaling plan.
Scaling is $8 per user per month with a 10-user minimum, so the floor is $80 a month, with a 30-day free trial and two free months for paying annually. Enterprise is for companies that want hands-on onboarding and top-tier support, and is quoted case by case. Because the answers are only as good as the pages, budget time to write the core pages and name an owner for each before the Slack integration pays off.
| Pros | Low per-user price; AI answers from your own pages |
|---|---|
| Cons | A 10-user minimum; answer quality follows page quality |
| Pricing context | Scaling $8 per user per month (10-user minimum, 30-day free trial); Enterprise on request. |
| Official source | Vendor pricing page |
Help Scout Docs
Best for: a public help center next to a shared inbox.
Help Scout Docs is the knowledge-base half of Help Scout, and it earns its place when customer-facing articles should sit directly beside the shared inbox where the unanswered questions arrive. It is built for customers reading articles, not for engineers writing internal runbooks.
The Free plan includes 5 users, 1 Inbox and 1 Docs site; Standard allows 2 Docs sites, Plus 3 and Pro 5, with extra sites at $20 a month when paid annually. Seats are $25 (Standard), $45 (Plus) and $75 (Pro) per user per month. AI Answers resolves questions from your articles at $0.75 per resolution, and new accounts get three months of free, unlimited resolutions.
| Pros | Free plan with a Docs site; articles feed AI Answers |
|---|---|
| Cons | Not an internal wiki; the Docs site count is capped per plan |
| Pricing context | Free (5 users, 1 Docs site); Standard $25, Plus $45, Pro $75 per user per month; AI Answers $0.75 per resolution. |

Zendesk Guide
Best for: knowledge base inside a large support operation.
Zendesk Guide is the knowledge-base side of Zendesk, linking customer-facing articles to tickets and support reporting. It suits an organization where agents, not authors, own the content.
Zendesk sells it as part of its plans rather than as a stand-alone price: Support Team is $19 per agent per month and Suite Team, which lists an AI knowledge base, is $55, with Suite Professional at $115 (all paid yearly). Pricing is primarily per agent, so a large number of occasional article authors will cost more than they do in a per-author or per-site model.
| Pros | Article-to-ticket linkage and support reporting |
|---|---|
| Cons | Priced per agent; suite complexity for a small docs project |
| Pricing context | Support Team $19, Suite Team $55 and Suite Professional $115 per agent per month, paid yearly. |
| Official source | Vendor pricing page |
Intercom
Best for: help articles that hand over to a conversation.
Intercom ties a public help center to its messenger and its Fin AI agent, so an article can answer the question or hand a customer to a teammate. The knowledge base is part of a support platform, not a stand-alone product.
The Essential plan lists a public help center, while Advanced ($85 per seat per month, 20 free Lite seats) adds the workflow builder and Expert ($132, 50 free Lite seats) adds SSO and multibrand help centers. Fin is billed at $0.99 per outcome, so the more your articles deflect, the more the AI line grows; model both before you commit.
| Pros | Help center, messenger and AI agent in one place |
|---|---|
| Cons | Seat plus per-outcome billing; not a place for internal engineering docs |
| Pricing context | Advanced $85 and Expert $132 per seat per month; Fin AI Agent $0.99 per outcome; 14-day trial. |
| Official source | Vendor pricing page |
Bloomfire
Best for: a searchable knowledge community across departments.
Bloomfire is a knowledge-sharing community more than a wiki: people publish answers, discuss them and find them through search, which suits sales, support and operations teams spread across locations who need to learn from each other rather than read a single handbook.
Its pricing page is a route to a demo: it invites you to request a demo to get started and publishes no figures. Ask for a trial population of sales or support staff rather than the whole company, because a community platform lives or dies on whether a moderator keeps questions answered and tags tidy in the first weeks.
| Pros | Community-style discussion and discovery |
|---|---|
| Cons | Quote-only; needs an active moderator |
| Pricing context | Pricing on request (quote-based): the pricing page leads to a demo request and lists no figures. |
| Official source | Vendor pricing page |
Stack Overflow for Teams
Best for: engineering questions with durable, searchable answers.
The product is now sold as Stack Internal (formerly Stack Overflow for Teams) and keeps the question-and-answer model engineers already know, which makes it a good fit for recording how a build, a deployment or an edge case was solved so the same question is not asked twice.
Its pricing page lists an Individual Starter plan with a free trial and an Enterprise Organization plan sold through sales, where price follows the number of Knowledge Flow Credits needed. Tagging discipline matters more here than in a wiki: untagged questions are the ones that never get found again.
| Pros | Q&A format engineers already use |
|---|---|
| Cons | Narrower than a general wiki; credits-based Enterprise pricing is quote-only |
| Pricing context | Starter has a free trial; the Organization plan is priced by Knowledge Flow Credits through sales. |
| Official source | Vendor pricing page |
Microsoft SharePoint
Best for: governed knowledge for a Microsoft 365 company.
SharePoint lets you create team sites for sharing information, files and resources, and it inherits identity, permissions and storage from Microsoft 365. It is the practical answer when the company already pays for Microsoft 365 and needs a governed intranet.
It comes bundled: Microsoft 365 Business Basic is $7.00 per user per month paid yearly, Business Standard with Copilot is $23.50 and Business Premium with Copilot is $32.00. Because the licence is shared with email and Teams, the incremental cost of SharePoint for an existing Microsoft customer can be close to zero; the real cost is the site architecture, permission groups and page templates someone has to design.
| Pros | Permissions and identity from Microsoft 365; bundled licence |
|---|---|
| Cons | Information architecture and administration are substantial |
| Pricing context | Business Basic $7.00, Business Standard with Copilot $23.50 and Business Premium with Copilot $32.00 per user per month, paid yearly. |

Selection guide
| If this is your problem | Shortlist and why |
|---|---|
| The same internal questions keep coming back in chat | Guru or Tettra. Tettra is $8 per user per month with a 10-user minimum; Guru is a quoted package built around verification and cited answers. |
| Customers need articles and a human fallback | Help Scout Docs, Intercom, Zendesk Guide or Document360. The first three attach the help center to an inbox; Document360 is the stand-alone documentation product with a custom quote. |
| One home for specs, handbooks and engineering answers | Notion or Confluence for general docs, Slab or Slite for a tidier reading experience, Stack Overflow for Teams (now Stack Internal) when the content is engineering Q&A, SharePoint when the company already licenses Microsoft 365. |
What a 15-person SaaS team pays
For fifteen people, Slite is 15 × $10 on Basic or 15 × $20 on Pro, Tettra is 15 × $8 (the 10-user minimum is already met). Slab and Confluence both have free plans for up to 10 users, which a 15-person company has outgrown, so budget for their paid tiers once you pass that line.
A company with no Microsoft subscription yet would pay 15 × $7.00 a month for the Business Basic licence that includes SharePoint.
For customer-facing documentation the unit is the support seat. A five-person support desk on Help Scout Standard is 5 × $25 a month, and the Free plan covers the same five people with one Docs site if the shared inbox is the only requirement.
Quote-only products (Guru, Document360, Bloomfire and the Stack Overflow for Teams Organization plan) do not fit a spreadsheet like this. Ask each for a price at your user count and, for Document360, at your number of workspaces and languages, since those are the inputs its page says drive the quote.
Switching and migration
Wikis export unevenly, so decide up front what you will migrate. Page text moves fairly well between Confluence, Notion, Slab and Slite; databases, macros and permission trees rarely do. Document360 says its team migrates content from Google Docs, Confluence, SharePoint and PDFs and that standard migration is included in most quotes, which is worth pricing against doing it yourself. Whichever tool you pick, migrate the fifty most-viewed pages first and leave the rest in the old system with a redirect banner, so you learn how search performs before you commit the archive.
Frequently asked questions
Is Notion good enough as a company wiki?
For a team under a few dozen people, yes: its pricing page shows a Free plan, paid plans charged per member, and free guests who can only open pages they are invited to. It becomes a weaker fit when you need enforced review dates, which is the problem Guru and Tettra are built around, or customer-facing articles tied to an inbox, which Help Scout Docs and Intercom handle.
What is the cheapest way to run a customer help center?
Help Scout’s Free plan includes 1 Docs site for up to 5 users, and a Standard seat is $25 per user per month with a second Docs site included. Zendesk’s entry plan is $19 per agent per month, and Intercom’s help center is part of seat plans that start from its Essential tier.
Why is Stack Overflow for Teams listed under another name?
Its own pricing page now titles the product Stack Internal and notes the former name. We keep the old name in the heading because most buyers still search for it.
