    One club.
    One system.

    Six areas on one data core: board, administration, club life, sports, finance, competition. Modular, multi-tenant, accounting-grade.

    The next expansion stage of the engine.

    01 — Context

    Clubs don't need patchwork.

    One tool for members, one for fees, one for dates, one for the website. None talk to each other.

    Where data is maintained multiple times, errors occur multiple times. The effort ends up where it least belongs: with the volunteers.

    clubbrain merges these areas into one data core. Join once, join everywhere. When someone leaves, they don't just vanish from accounting — they vanish from the billing run.

    02 — Pillars

    Three pillars. One system.

    001

    Club administration

    Full member records with custom fields, status tracking, online registration, departments, teams, family discounts.

    002

    Competitions

    Group and knockout tournaments, leagues with promotion and relegation, live management, team portal.

    003

    Finance

    Double-entry bookkeeping according to SKR 42, four tax spheres, cancellation duty instead of deletion, export to tax office.

    03 — Modules

    Core and expansion.

    Modules are activated per club — from free entry to full equipment. What isn't needed doesn't get in the way.

    04 — Tech

    Two role levels, one dividing line.

    Platform roles and club roles are separate. Managing the platform doesn't make you a board member — and vice versa.

    001

    Separation

    Data isolation at row level. Multi-department clubs further separate by department and team.

    002

    Traceability

    Accounting-relevant processes are cryptographically chained and logged. Subsequent changes are detectable.

    003

    Migration

    A ten-step assistant imports legacy data from old systems — with validation before writing.

    Join once, join everywhere.
