-Build orders may (optionally) have a target complete date specified. If this date is reached but the build order remains incomplete, then the build is considered *overdue*.
+### Start Date
+
+Build orders can be optionally scheduled to *start* at a specified date. This may be useful for planning production schedules.
+
+### Overdue Builds
+
+Build orders may (optionally) have a target completion date specified. If this date is reached but the build order remains incomplete, then the build is considered *overdue*.
+
+This can be useful for tracking production delays, and can be used to generate reports on build order performance.
 
-- Builds can be filtered by overdue status in the build list
