Everything your organization runs on, in one place.

GreekOS is organized around how Greek-letter organizations actually work — national policy flows down, chapter activity flows up, and members move through it all in real time.

Membership & Roster Management

One roster, three levels of visibility.

  • Full member lifecycle: prospective → pledge → active → alumni → disaffiliated
  • National-level roster visibility across every chapter, always current
  • Chapter-level roster management with role-based access
  • Status changes logged automatically for compliance and audit purposes
  • Member profiles that carry academic, contact, and involvement history in one place

Dues, Payments & Wallets

Money moves the way your org actually operates — without GreekOS in the middle of it.

  • Flexible dues structures: national dues, chapter dues, one-time or recurring
  • Member wallets for balances, event payments, and refunds
  • Chapter-to-national remittance handled directly — GreekOS never holds your organization's funds
  • Transparent, flat pricing on the platform side — no hidden per-member or per-transaction markups layered on top of what you already pay to process payments
  • Full transaction history at the member, chapter, and national level

Events & Attendance

  • Event creation with national, chapter, or private visibility
  • RSVP and capacity management, including waitlists
  • Paid events with tiered pricing by member status (active / pledge / alumni)
  • Attendance tracking that feeds into chapter reporting

Compliance & Reporting

Built for the audit you hope you'll never need — but will be ready for.

  • Immutable audit logs on every significant action across the platform
  • Configurable required reports (rosters, financial summaries, new-member reports) with national review and approval workflows
  • Status-change governance: chapters can update member statuses freely during an open reporting window, and everything outside that window goes through a formal approval flow
  • Exportable data for 990 filings and national compliance reviews

Multi-Tenant Architecture

Your organization's data lives in its own space.

  • Each national organization operates in its own isolated environment
  • Chapter data is scoped and access-controlled by role — chapter admins see their chapter, national admins see their organization, nobody sees what they shouldn’t
  • Enterprise-grade data separation without enterprise-grade complexity for your end users

Communication

Keep the whole organization in the loop.

  • Chapter and national announcements with priority levels and read tracking
  • Direct and group messaging within your organization
