Three plans by user count – one fixed monthly price, no pricing maze. Your data in Germany, in open formats, on a server registered in your name.
The price depends solely on your user count – a fixed monthly flat rate per plan, no per-seat counting, no hidden line items. Each plan monthly or annually (−10%).
Setup of your complete stack incl. security hardening, data migration and personal onboarding – one-time, separate from the monthly price. Book within 90 days of an audit and we credit 50% of the audit fee toward it.

An example with 120 users – Microsoft 365 + Slack + CRM vs. NexaStack Standard.
Your user count – a fixed monthly flat rate per plan: Standard €2,500 (80–150 users), Business €4,500 (150–300), Enterprise on request (from 300). No per-seat counting, no case-by-case pricing. Paying annually saves 10%.
The one-time setup (provisioning, hardening, data migration, onboarding) is billed separately from the monthly price: €2,500–5,000 depending on plan. If you booked an audit beforehand, we credit 50% of the audit fee toward setup when you sign within 90 days.
24 months, then it renews automatically for 12 months at a time unless cancelled three months before the end. If your company grows into the next user band, you move to the next plan – otherwise the monthly price stays fixed. You can take your data and configuration with you at any time (exit guarantee).
Yes – files, calendars, contacts and CRM data. What we don't migrate: email mailboxes. We don't run a mail server. Your existing email provider stays unchanged. Migration effort is quoted individually.
The server is registered in your name and the software is open source – no vendor can switch it off. Every contract includes a documented exit guarantee: your data in open formats plus full documentation of your setup, transferable to you or a third party at any time.
No. Setup is a one-time fixed price, operations a fixed monthly flat rate per plan – hosting, operations, updates, backups and support included. No per-seat reconciliation, no hidden line items. Additional migration work (e.g. large legacy data sets) is quoted transparently up front.
