Projects → Cost codes.

A project answers *which job*. A cost code answers *which part of the job* — excavation, framing, electrical, permits. Without it, a job with $400,000 of cost is a single number that cannot be managed.

**Setting one:** every document line carries a cost code alongside its project — on invoices as well as on bills and expenses, so both sides of a job break down the same way. A single invoice can carry several lines with different cost codes, which is how a progress bill against a schedule of values is built.

**In a split:** each part of a [Splitting one cost across several projects](https://intubu.intuitivecapital-dai.com/docs/cost-splits) can carry its own cost code, so one cheque can land on framing for one job and electrical for another.

**Codes are organised by division** and are unique within it, so two divisions can both have an "01" without colliding.

**Where they show up:** job cost by phase, estimate versus actual by code, committed cost against a code, and the construction edition's WIP schedule.
