Community of goods, also known as the common purse, simply means we share everything together. None of us owns any property in our name, and none of us receives a paycheck, stipend, or allowance. Everything belongs to the collective membership.
When someone becomes a member, all their earnings and inheritances are given to the church, and each receives necessities such as food, clothing, and housing. Each of us is accountable to the church community for money we spend. No one member, or any one Bruderhof location, is richer or poorer than any other.
This idea is not ours; this is how the first Christians lived, as described in Acts 2.
Our businesses are sufficient to maintain our communities and provide for our modest daily needs (and yes, the community pays for these things with money, not barter). When we are blessed with more than we need, we use it for our own outreach projects or to support other charitable missions.
