The short answer

Pick Zendesk if your support is ticket-first and email-heavy, with SLAs and a queue to manage. Pick 3CX if phone is your main channel and you want chat and WhatsApp to ring the same agents. For five people, 3CX is $275 a month cheaper than Zendesk ($275 a month on Zendesk against $0 on 3CX), before AI. Sellio Mini is $45, which only 3CX's figure comes under. Zendesk and 3CX both include website chat in the price; only Zendesk has email and Instagram; only 3CX has WhatsApp. Neither Zendesk nor 3CX includes Telegram outright. Below, a third option for a team of two to ten that wants what Zendesk and 3CX sell here at one price.

The six differences that decide it

Everything else on this page follows from these.

  1. 01

    Where a conversation starts

    ZendeskZendesk

    As a ticket. Every channel, chat included, becomes a ticket with a status, a priority and an SLA clock. 3CX has no ticket queue behind its conversations.

    3CX3CX

    As a call, or as a chat that rings the same agent queue; there is no ticket behind it. Zendesk raises a ticket where 3CX keeps a conversation.

  2. 02

    ZendeskZendesk

    $19 buys email and tickets. Live chat, WhatsApp, Instagram and AI agents start at Suite Team, $55. $275 for five people, against $0 on 3CX.

    3CX3CX

  3. 03

    How the AI is billed

    3CX3CX

  5. 05

    Beyond the inbox

    ZendeskZendesk

    A contact center: voice, workforce management, QA, and a marketplace of over a thousand apps. 3CX is a business phone system with live chat instead.

    3CX3CX

    The phone system itself: extensions, call queues, IVR, recordings and video meetings. Zendesk is a help desk suite instead.

  6. 06

    Time to the first reply

    ZendeskZendesk

    A project. Queue, SLAs, routing and macros are set up before the first ticket is answered. 3CX is a day for the phone system.

    3CX3CX

    A day for the phone system; minutes for the chat widget once the PBX is up. Zendesk is a project.

Which one, for whom

Pick Zendesk if

  • Your support is ticket-first and email-heavy, with SLAs and a queue to manage.
  • You need phone support and a contact center in the same tool.
  • You need email and Instagram in the price, which 3CX does not include outright.
  • You need a ticket queue, which 3CX does not have.

Pick 3CX if

  • Phone is your main channel and you want chat and WhatsApp to ring the same agents.
  • You want a free tier for a small team that already needs a PBX.
  • Five people cost $275 a month less than on Zendesk ($0 against $275), before AI.
  • You need WhatsApp in the price, which Zendesk does not include outright.

The third option: Sellio

  • You are two to ten people on Zendesk or 3CX who answer chat, messaging and email, and want to compare workspace pricing with $275 a month on Zendesk against $0 on 3CX for five people.
  • You want the AI bill known before the month starts: Zendesk meters AI (per automated resolution) above the seats, 3CX has no AI to bill (none for chat); Sellio includes a credit and lets you cap it.
  • You need Telegram, which neither Zendesk nor 3CX includes.

What two, five and ten people pay

Zendesk on Suite Team: $110, $275 and $550 a month for two, five and ten people, before AI. 3CX: $0 a month for five (five users on the free tier); it does not print a per-seat rate to extend to two or ten. Sellio: Free for two seats; Mini at $45 for five, $230 less than Zendesk and more than 3CX's $0 for five people; Essentials at $95 for ten, the AI credit included. At ten people, Essentials at $95 is $455 under Zendesk.

Where the two agree, and where they split

Zendesk is a help desk suite built around tickets and a queue; 3CX is a business phone system with live chat built around phone calls. Only 3CX has a free plan (up to 10 users, 3CX-hosted); Zendesk offers a 14-day trial of Suite Professional. Zendesk and 3CX both include website chat in the price; only Zendesk has email and Instagram; only 3CX has WhatsApp. Neither Zendesk nor 3CX includes Telegram outright. Zendesk meters AI (per automated resolution) above the seats; 3CX has no AI to bill (none for chat). Zendesk has tickets and 3CX does not, and only 3CX ships desktop apps. Zendesk is a project; 3CX is a day for the phone system.

What each price leaves out

Zendesk: AI agents are billed per automated resolution on top of the seat price; the Copilot add-on is $50 per agent per month. 3CX: No AI agent for chat; call transcription and analytics are listed as launching soon. Beside Zendesk's per automated resolution and 3CX's none for chat, Sellio includes an AI credit with each paid plan. Usage consumes that credit; additional credits cost extra, and you can set a spending cap.

How to decide in an afternoon

  1. Step 1

    Count agents and channels

    Anyone who replies is a seat. List the channels customers actually use.

    5 people reply5 seats
    Website chat61%
    WhatsApp27%
    Email12%
  2. Step 2

    Price the AI you would use

    Estimate monthly conversations the AI could close, then apply each vendor's per-resolution or per-session rate.

    1,200 conversations × 40% AI closes480
    ZendeskZendeskAssumed $1.5$720
    3CX3CXSee vendorNot quoted
    Sellio$0.05$19

    Illustrative AI-only estimate; vendor units differ. Pack billing is rounded up. Sellio assumes Mini’s $5 credit and $0.05 per conversation.
