Most live chat is billed per agent, every month, forever - and modern AI features often add a per-resolution meter on top. ZChat takes the other path: a one-time license you own, installed on your own server. Here's how the math differs, and an honest look at what you still pay for.
A monthly per-agent fee multiplies by your team size and repeats every month. Grow the team or add a seasonal agent and the recurring bill grows with it - the cost is tied to headcount, not value delivered.
AI answers are increasingly billed per resolution on hosted plans, so a busy month costs more. With ZChat the chatbot is included, and a local model means no AI usage fees at all.
A one-time license is a fixed, up-front cost. Agents aren't billable units and there's no monthly line item - you own the software and keep running it, even after update coverage lapses.
The shape of the cost, not a quote for any specific competitor.
A subscription can be the cheaper option in month one, especially for a tiny team. But because it recurs and scales with agents, a one-time license tends to come out ahead the longer you run and the more people you add. Run the numbers for your own team - agents times monthly rate times the months you expect to operate, against a single license plus your hosting.
One-time license covers
The full product - live chat, operator console, AI chatbot, webhooks, reports - for every agent, with a year of updates included and a source-code option.
You still pay for
Your own hosting (a server and a SQL Server database), and optionally renewing update coverage after year one. No fee to the vendor to keep running.
All prices one-time. No per-agent seats, no AI usage fees from ZChat. Source code license also available.
ZChat gives you the installable server, web dashboard, website widget, and desktop agent tools in one self-hosted product you buy once and keep. Run it on infrastructure you trust and connect AI only if and how you want it.

Install on Windows or Linux, behind IIS or Nginx, in a VM, or in Docker if that fits your stack.
