Church Management System

Summary

For The Church of Pentecost, Altherix designed, built and deployed a full congregation management platform. It replaced spreadsheets and paper registers with a single record of every member, group, event and attendance across the organisation's assemblies, and runs in production on Azure.

The challenge

Congregation data was held in spreadsheets and paper registers, so there was no single, reliable record of members, groups, events or attendance across assemblies.

The platform had to handle the real shape of church life: households and home cells, members moving between assemblies, services that recur every week with exceptions, and visitors who arrive without a record.

The approach

• Model the domain first. Member lifecycle — education and career history, salvation and baptism status, household and home-cell membership — modelled as first-class data rather than free text.
• Automate the paperwork. Inter-assembly transfers run as a request workflow that generates the transfer letter automatically.
• Treat recurrence properly. Recurring services are expanded into individual occurrences by a scheduled background job, so each occurrence can carry its own exceptions.
• Migrate, don't retype. Excel import and export so existing registers could be brought across in bulk.

Engineering

Live check-in

Real-time attendance capture over WebSockets, including visitors and anonymous attendees.

Background processing

Recurring events expanded into occurrences by a scheduled job, with per-occurrence exceptions.

Bulk data

Excel import and export for migrating existing registers.

Reporting

Dashboards and generated PDF reports for leadership.

Controls

Role-based access and audit logging throughout.

Impact

Congregation operations moved from paper and spreadsheets onto one system of record, live in production and delivered as part of a multi-year engagement that also produced the Missions Office Enterprise System.
