Document360 pricing is one of the more confusing questions for anyone evaluating standalone help-center tools in 2026, because the answer changed in late 2024. Document360 used to publish a public tier table (Free, Standard, Business, Enterprise). It now publishes plan names without prices and asks every new buyer to "Get a quote." Most online breakdowns still cite the old numbers as if they were current. The plan structure is real. The historical pricing is a useful anchor. The current quotes are higher than the old list. And the published number, whatever the quote ends up being, is the cheaper half of what you actually pay over three years, because Document360 has a great editor and a maintenance gap identical to every other help-center tool on the market.
This article walks through every Document360 plan as it exists in 2026, what each tier includes, what the historical Document360 pricing looked like before the shift to quotes, the AI Suite cost on top, the true total cost of ownership at 1 and 3 projects over three years, and what to verify before you sign. Then a short alternatives section for teams that realize at the end that they are paying for a help center that publishes well but does not maintain itself.
What is Document360?
Document360 is a standalone help-center and knowledge base platform built for SaaS companies that want a dedicated documentation product rather than the help-center module bolted onto a helpdesk. It is sold per project, not per user, and a project corresponds to one knowledge base (one product, one brand, one site). Document360 is not bundled with ticketing or messaging, which is part of its appeal: you can run Document360 alongside Zendesk, Intercom, or Help Scout and treat the knowledge base as its own surface.
Document360 as a product covers article authoring with a strong block-based editor, version history, workflows for content approval, multilingual content, public and private knowledge bases, AI Assist and Eddy AI for search and writing, analytics, and a customizable reader portal. What it does not do, the part the pricing model is silent on, is tell you when an article has gone stale because the product changed. That is the cost we will return to.
Document360 plans and what each tier includes
Document360 currently lists three plans for new customers, plus a Free option that was discontinued for new signups in November 2024. Every price below reflects the most recent public anchor (historical list price before the move to quotes), with an annotation on where 2026 quotes are landing in practice. All Document360 pricing is per project per month, billed annually.
What "per project" actually means
Document360 charges per project, where a project is one knowledge base. A SaaS company running one product on one brand has one project and pays once. The moment you add a second product, a developer-docs site, a partner portal, or a separate internal knowledge base, you pay for a second project. Two projects on Business is $599 to $999 per month at current quote ranges. This is the most commonly missed item in Document360 cost modeling. Multi-product teams budget for one plan and end up paying for two.
What changes at Business
Business adds multilingual knowledge base support (separate content per language inside one project), content reuse blocks, scheduled publishing, ticket deflector for chat widgets, and advanced analytics on search behavior. For most B2B SaaS teams selling internationally or running a serious content operation, Business is the realistic tier, not Professional.
What changes at Enterprise
Enterprise is bought for procurement-grade controls and security reviews, not editor features. The reason teams pay $799 or more per project is SAML SSO and SCIM, IP allowlisting, audit logs, white-label customization, and a dedicated customer success manager. For a 10-team-account deployment with security review requirements, Enterprise is the floor.
Why Document360 moved to quote-only pricing in late 2024
Document360 hid public prices from the website around November 2024 and migrated the Free plan out of new signups at the same time. The official explanation is "only pay for the features you need." The operational reality is that quote-only pricing lets a vendor charge different prices to different segments. A small SaaS team gets quoted at one number, a regulated enterprise gets quoted at another, and the deal-by-deal economics improve.
What this means for buyers: the published anchor is gone, so the negotiation lever of "I saw the price on your website" no longer exists. Comparable benchmarks become harder to find. The startup program (six months free on Business or Enterprise plus 50 percent off the next six months) is still available but eligibility is opaque. Most teams negotiating Document360 in 2026 should treat the first quote as a starting offer, not a list price, and expect 15 to 25 percent negotiation room on annual contracts.
Document360 AI Suite cost on top of the base plan
Document360 sells AI features (AI Suggest for related-article surfacing, Eddy AI for conversational search, AI-assisted writing) as an add-on, not bundled into the base plan. The pricing is quote-based and varies by plan tier and AI feature scope.
AI Suggest at roughly $99 to $149 per project per month
AI Suggest is the entry-level AI feature, surfacing related articles to readers based on intent. It is a per-project add-on and pricing scales with article volume. Teams on Professional typically see quotes in the $99 to $149 per project per month range. Business and Enterprise tiers see higher per-project AI prices, partly because the AI features are deeper (multi-language support, custom prompts).
Eddy AI conversational search
Eddy AI is the conversational search and AI-answer surface, the closest Document360 product to Intercom Fin or Zendesk AI Agent. Pricing is per-conversation or per-resolution, comparable to the $0.50 to $1.00 per resolution band the rest of the help-center market has adopted. For high-traffic knowledge bases, Eddy AI can quickly become the largest single line on the Document360 invoice.
The AI accuracy problem the pricing page does not mention
Every Document360 AI feature reads from your articles. AI Suggest surfaces them. Eddy AI quotes them. AI-assisted writing rewrites them. When an article is six weeks behind the product, every AI surface that touches it propagates the stale information. The AI features amplify the freshness problem, they do not solve it. This is structural to every AI-on-top-of-static-docs architecture.
Document360 total cost at 1 and 3 projects over three years
License cost is the visible line. AI add-ons are the second line. Maintenance labor is the invisible third one. Every Document360 deployment that survives past month six requires somebody to update articles when the product ships, audit dead content quarterly, fix screenshots after UI changes, and keep multilingual versions aligned. For most SaaS teams shipping weekly, that work runs 8 to 12 hours per month per project. Fully-loaded support and docs labor at $75 per hour in the US, or 65 to 70 euros per hour in DACH, makes this a real number.
1 project, Business plan, three years
Business license at $449 per project per month average quote: $449 x 36 months = $16,164. AI Suggest add-on at $129 per project per month: $4,644. Eddy AI at modest 1,500 conversations per year at $0.75: $3,375. Maintenance labor at 10 hours per month at $75 per hour over 36 months: $27,000. Total: $51,183. License is 32 percent of the three-year cost. Maintenance is 53 percent.
3 projects, Business plan, three years
Three projects on Business at $449 average each per month: $48,492 over 36 months. AI Suggest add-on at $129 per project per month for three projects: $13,932. Eddy AI at 4,500 conversations per year at $0.75 across projects: $10,125. Maintenance labor for a three-product team at 30 hours per month: $81,000. Total: $153,549. Maintenance is again the largest single line, larger than the entire AI bill, and 53 percent of total spend.
The breakdown matters because it changes how you should think about the price. You are not buying a help center. You are buying a help center plus a recurring labor commitment that scales with how often the product changes. If the product ships weekly, the maintenance line grows. Documentation decay is the hidden cost of every help center, and Document360 is no different from its competitors on this dimension despite having one of the better editors on the market.
The maintenance cost no Document360 pricing article mentions
Document360 is excellent at publishing. The editor is genuinely strong. The version history is clean. The workflow approval is well-built. What Document360 is silent on is whether the articles it publishes are still correct three months after they were written. The platform has no concept of "this article references a UI element that no longer exists in your product." There is no link between code changes in your product and content drift in your knowledge base. When the product team ships a UI change on a Tuesday, the Document360 article is wrong on Tuesday afternoon. Nobody on the support side knows until a customer files a ticket.
This is structural, not Document360-specific. Every traditional help center has the same blind spot. The cost shows up as agent time answering tickets the help center should have deflected, as customer-success time correcting incorrect onboarding flows, and as the eventual cost of replacing every screenshot that broke after the last redesign. For teams shipping weekly, the maintenance interval needs to match the release interval. Most teams set up a monthly content review, fall behind by month four, and either accept the drift or hire a dedicated docs person.
Document360 hidden costs and what to verify before signing
The published per-project price is the floor. Six categories of cost stack on top before your effective spend reaches reality. Verify each one in writing before you sign a multi-year contract.
- Per-project economics. A second product means a second project at the same per-project rate. Confirm whether your team operates on one knowledge base or several before committing.
- Team account caps. Professional includes 3 team accounts, Business includes 5, Enterprise includes 10. Additional team accounts bill separately, usually at $20 to $40 per additional account per month.
- Reader pricing. Private knowledge bases bill for readers (the end-customer logins that access gated content). Reader prices scale with volume and are negotiated separately.
- AI feature add-ons. AI Suggest, Eddy AI, AI writing assistance all bill on top of the base plan, often per project. A multi-project AI-on rollout adds 30 to 80 percent to the base bill.
- Annual vs monthly billing. Annual unlocks the published price. Monthly is offered but typically 15 to 25 percent higher. Multi-year deals can land 10 to 20 percent below annual list.
- Renewal increases. Document360 renewals commonly come in at 10 to 20 percent year-over-year, often tied to AI feature additions you may not need. Negotiate a renewal cap (5 to 8 percent) before the first signature.
When Document360 pricing makes sense, and when it does not
Document360 is the right choice for content-led organizations: teams where the knowledge base is the primary self-service surface, the article authoring volume is high, the help-center editor is a core daily tool for the documentation team, and the helpdesk side is handled by a separate vendor. Document360 has a stronger pure-documentation editor than Zendesk Guide or Intercom Articles, and the per-project model fits single-product B2B SaaS cleanly.
It is the wrong choice for teams running two or more products on different brands, where the per-project pricing stacks fast. It is also a poor fit for teams shipping weekly where maintenance labor dominates the TCO and the editor strength is not the bottleneck. For an honest comparison of help center tools by team profile, Document360 shows up as the strongest pure-editor choice for single-product teams and a worse fit for fast-shipping multi-product teams. See a direct comparison between HappySupport and Document360 for the architecture difference.
An open-access resource on the maintenance side of knowledge management is the Service Innovation Library, which covers the KCS (Knowledge-Centered Service) methodology and includes practical material on how to keep a help center current as the product evolves. KCS is platform-agnostic and applies regardless of whether you run Document360, Zendesk Guide, or any other tool.
Document360 alternatives by team profile
Three honest alternatives to consider, depending on where you sit:
- Zendesk Guide. Stronger for support-led teams that need the help center bundled with ticketing. See our Zendesk Guide pricing breakdown for the comparable math.
- Help Scout Docs. Cheaper and simpler, bundled into Help Scout's helpdesk. Good fit for small to mid-market teams. Limits at multi-brand and multilingual.
- HappySupport. Built for product-led SaaS teams shipping weekly. Different category from Document360: the focus is on keeping the help center current automatically as the product changes, not on the strongest editor in the market.
HappySupport in this context
HappySupport is a different category of tool than Document360. Document360 solves the publishing problem: how do you let teams write articles, how do you organize them, how do you make them searchable. HappySupport solves the freshness problem: how do you keep those articles accurate when the product ships every week. The architecture is DOM/CSS recording in a Chrome extension (HappyRecorder), which captures UI flows as code-selectors instead of pixels, paired with HappyAgent GitHub Sync, which watches the product repository for changes that affect documented flows and flags the affected articles for update. The maintenance labor line in the 3-year TCO model above is the line HappySupport is built to compress. For teams whose release cadence is faster than their content-review cadence, the math shifts: instead of license plus growing maintenance debt, you get license plus capped maintenance time.
