A secure, scalable membership database for signups, communication, events, and reporting, tailored to how nonprofits actually run their operations.

The Challenge

The organization was managing member data across scattered spreadsheets, manual payment logs, and disconnected email lists. Staff spent hours reconciling dues payments against membership status, volunteer coordinators had no easy way to track engagement, and every email campaign required a tedious manual list export. On top of that, several affiliated chapters each needed their own branded portal, but none of them could afford a separate system.

Our Approach

We built a unified membership platform using React with TypeScript for a modern, type-safe frontend, backed by Supabase's PostgreSQL database with built-in authentication and row-level security. The multi-tenant architecture lets multiple chapters share infrastructure while keeping their branding, member data, and configuration completely separate, all from a single codebase deployed to Vercel.

Key Features

  • Smart Dues Tracking: Automatically calculates membership status against a $25/year threshold, with a grace period (Oct through Dec) where payments count toward both the current and next year
  • Volunteer Hour Logging: Members log their own hours while coordinators generate engagement reports and recognize top contributors
  • Payment Platform Integration: Imports donation records from external payment processors with intelligent reconciliation that catches duplicates and matches payments to member profiles
  • Constant Contact Sync: One-click export of member segments to email marketing campaigns via OAuth2 integration
  • Multi-Chapter Support: A shared database serves multiple organizations with custom branding, colors, social links, and donation URLs per chapter

    • The Results

  • Consolidated five-plus data sources into a single source of truth
  • Cut payment reconciliation time from hours down to minutes
  • Enabled self-service member registration and profile management
  • Gave chapter leaders real-time membership status dashboards
