Payment schedule
Payment schedule is one of Demiton's published registers for Australian civil construction. The payment schedule answering a progress claim under Security of Payment legislation. 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.
