Most church software was built for megachurch or Baptist polity and adapted for everyone else. Reformeer was built from the ground up on Reformed church order: household registers with baptism and profession of faith, elder-led ward shepherding, deacon-managed diaconal funds, confessional letters of transfer. The same polity the OPC has maintained since 1936.
Six parts that work as one. Start with what presses hardest; grow into the rest.

“The migration from our previous system was simple and accurate, without a single member record falling through the cracks. Good administration contributes to good ministry, and for that we are very grateful to Reformeer.”
Reformed Intelligence searches 930+ primary sources and answers with exact citations. No hallucinated quotes. No internet scraping. Every claim linked to a real document, including the complete OPC General Assembly minutes from 1936 to 2025.
Example questions
Other church not on Reformeer? We email the request, no account needed.
When a member moves to another OPC congregation, the new church requests the letter of transfer in Reformeer. The old church approves it. Membership transfers automatically, no re-capture, no paper forms. If the other church isn't on Reformeer yet, we email the request; their reply comes back into the conversation.
Office-bearers in the Gereformeerde Kerke in Suid-Afrika (GKSA) build and maintain Reformeer, part of the same broad Reformed family as your churches. We built what our own congregation needed, then opened it to the wider Reformed and Presbyterian world.
Built and maintained by confessional Reformed office-bearers in the GKSA.
Most church software charges per member, per user or per module. Reformeer is one flat price for the whole church, with unlimited members and the cited Reformed AI included.
No per-seat fees, no contracts. Every office-bearer gets their own login. Cancel any time.
