Plumbline
CHURCH ANALYTICS, BUILT ON PLANNING CENTER

The analytics layer Planning Center was missing.

Planning Center answers how many. It doesn't answer who, and is it getting better. Plumbline computes the metrics that matter and turns them into work queues, named lists of real people someone can actually go and love this week.

Why “Plumbline”?

A plumb line is one of the oldest tools there is. It's a weight on a string that hangs perfectly straight, so a builder can tell whether a wall is truly upright or only looks it.

In Amos 7, God stands by a wall with a plumb line in his hand and says he is “setting a plumb line among my people.” It's a picture of measuring them against a true, unchanging standard rather than appearances.

That's the heart of this tool. Not vanity metrics or a prettier headcount, but an honest measure of the church against what's true, with every definition out in the open so it can be trusted, questioned, and acted on.
