Mattermost Enterprise Advanced 11.x uses a simple formula: $350 base license (covers 5 users) plus $4 per additional user above the first 5. For example, a 20-user team pays $350 + (15 × $4) = $1,550/year. There are no hidden fees, support tiers, or module add-ons in this model.
The minimum is $350, which covers a base license for up to 5 activated users. Even if you have 1, 2, or 3 users, the cost is still $350 — the base includes 5 seats by default.
Enterprise Advanced is the highest Mattermost tier. It includes everything in Professional plus: AI-powered Intelligent Mission Environment (IME), High Availability clustering, LDAP/AD with nested groups, advanced compliance and eDiscovery exports, custom data retention policies, Microsoft Teams interoperability, self-hosted push notification server, advanced audit logging, and 24/7 support with 4-hour SLA.
Yes. Professional ($10/user/month officially) covers SSO, guest accounts, custom groups, and priority support. Enterprise Advanced adds HA clustering, AI/IME features, full compliance tooling, LDAP nested groups, and the self-hosted push server — critical for regulated industries, government, and large-scale deployments.
This pricing covers Mattermost Enterprise Advanced 11.x, including the current stable release 11.7.2 (May 27, 2026) and all 11.x patch releases going forward.
After receiving your .mattermost-license file: log in as System Administrator → go to System Console → About → Edition and License → click Upload License Key → upload the file → Save. Enterprise Advanced features activate immediately without restarting the server.
When a Mattermost Enterprise license expires, there is a 10-day grace period during which your instance continues running normally with full feature access. After the grace period, the instance downgrades to the free Entry tier — message history is preserved but Enterprise features are disabled until the license is renewed.
