The question asked, verbatim: best knowledge base software for small businesses. This page records one answer on one date. It is a measurement, not a ranking and not a recommendation.

Brands named, in the order the engine gave

1. Internal mentioned
   Internal - docs for your own team
2. Notion recommended
   Notion - My default recommendation for most small businesses.
3. Tettra mentioned
   Tettra - The cheapest credible option, from about $4-5/user/month, but with a 10-user minimum so figure a $40-50/month floor.
4. Slack mentioned
   It's Q&A-driven: someone asks a question in Slack, the answer gets saved as an article.
5. Guru mentioned
   Guru - Pick this if the problem is that nobody reads the wiki.
6. Slite mentioned
   Slite - Simpler and more opinionated than Notion, with AI that flags stale docs so your documentation doesn't quietly rot.
7. Confluence mentioned
   Confluence - Only if you're already on Jira.
8. Jira mentioned
   Confluence - Only if you're already on Jira.
9. Customer-facing mentioned
   Customer-facing - a public help center
10. HelpDocs mentioned
    HelpDocs - Where I'd start if you want a public help center and nothing else.
11. per-seat mentioned
    Flat ~$129/month, no per-seat math, built explicitly for teams with no dedicated docs person.
12. Zendesk mentioned
    Zendesk Guide - The right call if you also need a ticketing system, since Guide comes bundled with the Suite.
13. Zendesk Guide mentioned
    Zendesk Guide - The right call if you also need a ticketing system, since Guide comes bundled with the Suite.
14. Helpjuice mentioned
    Helpjuice - Flat-fee, from $249/month for 30 users.
15. Document360 mentioned
    Document360 - Strong product, but it's quote-only with no published pricing, which in practice signals enterprise deal sizes.
16. Notion Plus mentioned
    Both at once on a tight budget: Notion plus a free Zendesk trial beats buying two mid-tier tools.

The answer, as recorded

The honest answer is that "knowledge base" means two different products, and picking the wrong category is the most common mistake. So here's both, in the order I'd actually suggest them. ## Internal - docs for your own team **1. Notion** - My default recommendation for most small businesses. One tool covers wiki, SOPs, project tracking, and client docs, so you're not paying for three subscriptions. ~$10/user/month annually, $20 for the Business tier if you want the full AI search. Downside: it's a blank canvas, so without someone imposing structure it becomes a junk drawer within a year. **2. Tettra** - The cheapest credible option, from about $4-5/user/month, but with a 10-user minimum so figure a $40-50/month floor. It's Q&A-driven: someone asks a question in Slack, the answer gets saved as an article. Good fit if your real problem is "only Dana knows how to do this." Narrower than Notion by design. **3. Guru** - Pick this if the problem is that nobody reads the wiki. It surfaces answers inside Slack, your browser, and your CRM rather than making people go look. ~$10-15/user/month, but there's a 10-seat minimum, which makes it awkward under roughly 8 people. **4. Slite** - Simpler and more opinionated than Notion, with AI that flags stale docs so your documentation doesn't quietly rot. Roughly $10-20/user/month. Worth a look if Notion has already failed for you once. **5. Confluence** - Only if you're already on Jira. Otherwise it's heavier than you need. ## Customer-facing - a public help center **1. HelpDocs** - Where I'd start if you want a public help center and nothing else. Flat ~$129/month, no per-seat math, built explicitly for teams with no dedicated docs person. No free tier. **2. Zendesk Guide** - The right call if you also need a ticketing system, since Guide comes bundled with the Suite. $55/agent/month on Suite Team annually. Key detail people miss: readers are free, you only pay for staff who write and edit. At 5 agents that's ~$275/month for helpdesk plus KB. **3. Helpjuice** - Flat-fee, from $249/month for 30 users. Beats Zendesk only if you genuinely need just a knowledge base with no ticketing attached. **4. Document360** - Strong product, but it's quote-only with no published pricing, which in practice signals enterprise deal sizes. Skip unless you have multiple products or versioned docs. ## What I'd do Under 15 people, internal docs: **Notion**. Public help center for customers: **HelpDocs**, or **Zendesk Guide** if tickets are also a problem. Both at once on a tight budget: Notion plus a free Zendesk trial beats buying two mid-tier tools. One caveat worth stating: the hard part is never the software, it's that nobody maintains the content. Tettra, Guru, and Slite are the three above that actively nag you to keep articles current - if you've already abandoned one wiki, that feature matters more than price.
