From recipe to finished goods — fully traced.

Bill of Materials management supports versioned recipes with explicit version numbers. Multiple versions can coexist for the same product, allowing you to maintain historical formulations while developing new ones. Versions are managed with soft-delete via an is_active flag, so deactivated recipes remain available for reference and traceability without cluttering the active recipe list. Each BOM item specifies a raw material, quantity per unit with decimal precision, and unit of measure.

Manufacturing runs as an atomic transaction — the system fetches BOM items, consumes raw materials using the configured strategy (FIFO or FEFO), and creates a finished product lot in a single operation. This ensures that inventory is never left in an inconsistent state, even if an error occurs mid-process. Raw material movements are linked to the finished product via related_finished_product_id, enabling complete backward traceability from any finished product to every raw material lot that went into it.

Product conversions allow repackaging finished goods with configurable ratios — for example, converting 1 case into 12 individual units. This is essential for food manufacturers who produce in bulk quantities and sell in multiple package sizes. The production calendar marks production and non-production days, with automatic US holiday detection covering New Year's Day, Memorial Day, Independence Day, Labor Day, Thanksgiving, and Christmas. Days can be manually toggled with notes for plant shutdowns, maintenance windows, or special production runs.
