Savings proposal

A 25-agent team on Zendesk Suite Professional pays about $2,875 a month. Self-hosting Zammad costs about $576 a month to run plus $2,880 to set up, so it pays for itself in month 2 and saves about $79,884 over three years.

List price: Zendesk Suite Professional, billed annually. Marked most popular. Suite Team is $55 per agent. Source, checked 2026-10-07.

Assumptions you can change

Self-hosting Zammad usually means several services (analytics store, queues, search). Hours are for one engineer; the server cost is a typical cloud VPS with backups and grows with the number of people using it.

Not included: paid editions or features of Zammad (see What's free?), large data migrations, and compliance work. All amounts in US dollars at list price; your negotiated price may differ.
