Purchase order
Purchase order is one of Demiton's published registers for Australian civil construction. Purchase orders raised against suppliers: committed spend not yet posted. Demiton keeps it current from the systems a contractor already runs and publishes the record's shape as a versioned JSON Schema, so the same question works whichever system produced the record.
