Churches run on spreadsheets and memory until B1Admin gives members, visitors, groups, attendance, and giving one shared home that the whole staff can trust. You keep detailed records on members and guests, follow up with visitors before they drift away, and coordinate small groups with their own rosters and communication. Sunday morning runs smoother with attendance tracking and a self check-in app, so families register children and members mark themselves present without a paper bottleneck at the door. Donations are tracked with detailed reports for the treasurer, online giving connects through Stripe, PayPal, or Kingdom Funding with recurring gifts and webhook-confirmed settlements, and custom forms collect registrations, signups, and requests without a separate forms tool. The same deployment serves your public website at the root, the admin dashboard for staff, a member portal where congregants manage their own information, and an API for integrations, all behind automatic HTTPS on one domain. Upgrades back up your data first, and because it is free and open source, a small church gets the same system as a large one.
