Frequently Asked Questions
01 What does Confluence cost for a 50-person IT team?
For 50 users, Confluence Free provides basic features at $0. The Standard plan costs $320/month ($6.40/user/month annually), adding unlimited storage, audit logs, and better support. Premium costs $615/month ($12.30/user/month annually) with 99.95% SLA, SAML SSO, and data residency. Most mid-size IT teams find Standard sufficient.
02 Is BookStack secure enough for enterprise IT documentation?
Yes, BookStack supports LDAP/SAML authentication, role-based permissions, and audit logs when self-hosted properly. Since you control the infrastructure, security depends on your deployment—use HTTPS, regular updates, and backups. Many enterprises use BookStack for internal documentation. However, you're responsible for security patches and compliance, unlike managed Confluence.
03 Can Confluence integrate with our IT tools?
Confluence integrates deeply with the Atlassian ecosystem (Jira, Opsgenie, Statuspage) and has 3,000+ marketplace apps for tools like ServiceNow, PagerDuty, Slack, and monitoring platforms. The REST API enables custom integrations. This makes it ideal for IT teams already using Jira for ticketing or wanting centralized documentation across tools.
04 How does Tettra compare to Confluence for IT teams?
Tettra is simpler and more affordable ($5-8/user/month vs $0-12.30 for Confluence) with excellent Slack integration for quick answers. However, it lacks Confluence's advanced features: no macros, limited integrations, basic permissions, and fewer formatting options. Choose Tettra if you prioritize simplicity and Slack workflows over comprehensive documentation capabilities.
05 Should internal IT teams consider MSP tools like IT Glue?
Generally no. IT Glue ($29-44/user/month) and Hudu ($27-29/user/month) are designed for MSPs managing multiple client environments. Internal IT teams don't need multi-client organization or MSP-specific integrations, making these tools unnecessarily expensive. Confluence, BookStack, or Tettra provide better value for documenting a single organization's infrastructure and procedures.
06 What hidden costs should I watch for?
Common hidden costs include setup/onboarding fees, data migration services, training and professional services, premium support plans, additional users beyond base tier, API access, storage overages, and feature add-ons.
