Document360

Document360 is a purpose-built knowledge base platform aimed at companies that want to reduce support ticket volume through structured self-service documentation. Founded in 2017 and headquartered in London, it sits in a narrower category than full client portal suites — it does documentation and help centers extremely well, but doesn't touch invoicing, project management, or file sharing.

What it does well

The editor experience is genuinely flexible: you can write in a WYSIWYG mode similar to Microsoft Word, or switch to a split-screen Markdown editor with live preview and syntax highlighting. Both support slash commands for inserting images, videos, code blocks, callouts, and tables. Articles live inside a hierarchical category structure, and you can create multiple distinct "knowledge bases" within a single project — useful when you need separate hubs for different products, audiences, or departments.

AI features are baked throughout rather than bolted on. The AI Writing Agent can generate full articles from a prompt, uploaded video, audio file, or text document. It also auto-generates FAQs, article summaries, glossary definitions for technical terms, and related article suggestions. Search uses an AI layer that returns ChatGPT-style direct answers rather than just a list of links.

Pricing

Document360 offers a free plan, with paid tiers starting at $149/project/month (billed annually) for the Standard plan. The Growth plan, aimed at mid-sized teams, adds custom workflow builders, an embedded help widget, PDF import, pro analytics, and integrations with 30+ tools including Zendesk, Intercom, Freshdesk, Slack, and Google Analytics. Enterprise unlocks SSO via Okta, Entra ID, Google, ADFS, OneLogin, Auth0, and AWS SSO; security audit trails; IP access restrictions; a staging/testing environment; and dedicated design support.

Pricing is per project, not per reader — which works well for customer-facing documentation where you may have thousands of readers but only a small writing team.

Integrations and compliance

The 30+ integrations cover helpdesk tools (Zendesk, Freshdesk, Intercom), team chat (Slack, Microsoft Teams), analytics (Google Analytics, Segment), and translation services. A public REST API is available on Growth and above. Auto-translation covers 50+ languages. The platform includes WCAG accessibility compliance tooling, cookie consent banners, and audit trails to support security and compliance requirements.

Analytics

Analytics go deeper than basic page views. The Pro Analytics Dashboard (Growth tier and above) surfaces search term reports showing what users are looking for and failing to find, broken link detection, feedback analytics, page-not-found tracking, and ticket deflection rates. Customer case study data cited on the site includes a 30% reduction in support tickets and a 30% increase in documentation traffic after adoption.

Limitations

Document360 is squarely a documentation tool — not a client portal in the broader sense. There's no task management, client messaging, e-signature, invoicing, or file vault functionality. If your use case extends beyond knowledge base and help center, you'll need to pair it with other tools. The higher-tier features that matter most for enterprise use (SSO, audit trails, staging environments, API access) require the Growth or Enterprise plans, which can get expensive as team size grows. Support is 24/5, not 24/7.
