Zendesk

Zendesk's Suite Professional plan costs $115/agent/month. Billed annually; $149/agent/mo month-to-month. Copilot adds $50/agent/mo, and AI agent usage above the included 10 automated resolutions per agent per month is billed per resolution, at a rate Zendesk does not publish. For comparison, Converge costs $49/month flat for up to 15 team members.

Zendesk is best suited for large enterprises needing comprehensive ticketing with compliance requirements and deep third-party integrations. Its standout feature is industry-leading ticketing system with 1,800+ marketplace apps, partners and integrations, plus enterprise-grade compliance.

Zendesk pricing is built from four multipliers, not one list price. First, the tier: on Zendesk's pricing page, re-checked 12 September 2026, Support Team is $19/agent/mo, Suite Team $55, Suite Professional $115, and Suite Enterprise + Copilot carries no public price at all. Second, the billing term — those figures are annual rates; month-to-month costs $25, $69 and $149 respectively, roughly 30% more. Third, seat count, because every figure is per agent per month. Fourth, add-ons and usage: Copilot at $50/agent/mo, the Workforce Engagement Bundle at $50/agent/mo, Contact Center at $83/agent/mo, and AI resolutions billed past your plan allowance. Only the first multiplier is on the sticker.

At the annual Suite Professional rate of $115/agent/mo: 5 agents cost $575/month ($6,900/year), 10 agents $1,150/month ($13,800/year), and 15 agents $1,725/month ($20,700/year). Add Copilot at $50/agent/mo and those become $825, $1,650 and $2,475 per month ($9,900, $19,800 and $29,700 per year). On the cheaper Suite Team plan at $55/agent/mo, the same headcounts run $275, $550 and $825 per month. Pay monthly instead of annually and the Professional 5-agent figure rises from $575 to $745. For reference, Converge is $49/month flat for up to 15 agents, so the 15-agent Professional-plus-Copilot scenario is about 50x that.

Partly, and Zendesk says so itself rather than leaving it to rumour. Its pricing FAQ confirms subscriptions run month-to-month, annually, or multi-year, that annual terms are "usually discounted", and that enterprise plans generally require sales engagement — which is where any real negotiation happens. Volume commitments are the main lever: Zendesk's own documentation says buying 100 or more automated resolutions up front ("committed usage") "provides a better per-resolution cost than overage billing", though it publishes neither rate. Zendesk publishes no discount percentage anywhere either, so treat any specific figure you read elsewhere as someone's anecdote, not a rate card. If you qualify, the Zendesk for Startups program is the largest published concession: up to two years free for companies under 250 employees, at or before Series B, and under ten years old.

There is no standalone knowledge base price — it is a plan gate. Support Team ($19/agent/mo) includes no help center at all. The first plan that gets one is Suite Team at $55/agent/mo, which allows a single help center, in one language, nested up to two levels, on standard themes only. Suite Professional at $115/agent/mo raises that to five help centers, 40+ languages, custom and marketplace themes, community forums, a customer portal, and content history. So the practical answer to "what does the knowledge base cost" is the gap between the plan you would otherwise buy and the plan that unlocks the depth you need — for a team wanting multilingual self-service, that is the $55-to-$115 step, or $720/agent/year.

Because Zendesk bills by seat type, not headcount. A full agent seat costs the plan rate. Light agents — people who read tickets and add internal notes but never reply to customers — are included at no charge up to 100 on Suite Professional, with a paid light-agent add-on beyond that. Contributors and end users are free. The catch that surprises finance teams is seat parity: adding one Suite seat adds a seat across every product in the Suite, so you cannot buy eight Support seats and three Talk seats. Usage-metered items also vary per person in effect — automated resolution allowances are granted per agent per month, so a team of ten pools ten allowances regardless of who consumes them.

By outcome, on top of the seat price. AI agents are included on every Suite and Support plan, and Zendesk bills them in automated resolutions: you pay "only for customer requests that were successfully resolved by the AI agent, without any escalation to a human agent". Each plan carries a monthly allowance per agent — 5 on Team, 10 on Professional, 15 on Enterprise, capped at 10,000 per account per year, with light agents excluded from the calculation. Past the allowance you are billed per resolution; Zendesk publishes no per-resolution rate on any public page, only the statement that pre-purchasing 100 or more ("committed usage") costs less per resolution than overage billing. Any specific dollar figure you find for this is someone's quote, not a rate card. Copilot, the agent-facing assistant, is a separate $50/agent/mo add-on and is not the same product. One caveat worth reading before you model any of it: that 5/10/15 table is published in the article describing the platform in place before 18 May 2026. On that date Zendesk introduced resolution tiers, under which assisted escalations and contained resolutions no longer draw down the allowance and only verified resolutions do — so check which platform your account is actually on.

No — both names are stale, which is why pricing for them is impossible to find. Zendesk Connect, the outbound campaign product from the 2017 Outbound.io acquisition, was announced for removal in October 2020 and removed on 31 October 2021. Its capability now lives inside Suite as proactive messages, with no separate SKU: available on every Suite tier, limited to Web Widget and mobile SDK, capped at 140 messages, and not supported on social channels. Zendesk Plus is not a current plan either. It is most often a half-memory of Suite Enterprise Plus, the sales-quoted top tier, or of the pre-2015 legacy "Plus" Support plan that became today's Professional. Two more retired names cause the same dead-end pricing search: Smooch, which Zendesk acquired in 2019 and renamed Sunshine Conversations, and Zendesk Chat, which no longer carries a price of its own — we reconcile both, and the stale rate cards still circulating for them, in Smooch and Zendesk Chat compared.
