Which one is for you
Pick Kayako if
- Fits if refunds and exchanges are most of your tickets and you want to pay per resolution
- Works for a team that wants the vendor to do the setup
Look elsewhere if
- Skip it if you want to see a price for the help desk, as Kayako One's is not published
- Not for you if you want to sign up and start alone, since the vendor sets it up
- Watch out: only fully resolved tickets cost $1, and a resolution means Kay solved it with no human agent
- Watch out: no free plan or trial is on record
Pick Zendesk if
- Fits if your team answers email, chat and phone and wants one queue for all of it
- Works for funded startups, which can get Suite Professional free for 6 months
Look elsewhere if
- Pricey if you need live chat or a help center, as both start at $55 an agent billed yearly
- Too light for chat-first teams on the $19 plan, which covers email tickets only
- Skip it if you need a fixed bill, since AI resolutions past the allowance cost $1.50 to $2 each
- Watch out: Copilot is a $50 an agent add-on, and phone numbers and call minutes are billed on top
- Watch out: the listing doesn't say whether the trial needs a card, and Suite Enterprise is sold only through sales
How we grade them
| 1.8GPAKayakoWeak | 2.4GPAZendeskFair | |
|---|---|---|
| Value for money | CKay is $1 per resolved ticket with no seat fees, but no price is published for Kayako One, so it can't be set against the category's $29 middle. | DSupport Team is $19 an agent billed yearly, a little under this category's middle, but it's email tickets only. Chat, phone and a help center start on Suite Team at $55 an agent, above the dearest tenth of help desks, and extra AI resolutions are $1.50 to $2 each. |
| Free plan and trial | FNo free plan and no trial are on record, and the pages we read show nothing to try before paying. | CA 14-day free trial of Suite Professional with Copilot, which shows you the top of the range. There's no free plan, and the listing doesn't say whether the trial needs a card. Funded startups can get 6 months free. |
| Features | CA help desk with ticketing, shared inbox and knowledge base, plus Kay, which acts through connected systems. The listing says little about the help desk's own limits, and a resolution counts only if no human was needed. | BTicketing across email, chat, social and phone, AI agents on every plan, help centers in 40+ languages with forums, voice numbers in 75+ countries, an IVR and reports you ask for in plain words. The whole job is covered. |
| Ease of use | CNo store rating on record, and the page says Kayako's team sets up the platform for you. | B4.5 from 4,219 App Store ratings for the agent app. Prebuilt dashboards and pre-written replies come on every plan, but routing, triggers and automations take setting up. |
| Platforms and integrations | BWeb only, with 7 listed integrations. No phone or desktop app on record. | BWeb, iPhone and Android, with WhatsApp, Facebook, Instagram, X, Slack, WeChat and LINE as channels, and an API. No desktop app, which keeps it off an A. |
| Best for | an AI agent paid per resolved ticket | support teams handling email, chat and phone |

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
