Build a bill of materials

A BOM lists the ingredients and packaging for one yield of a product. The active version drives costing and packaging deduction.

A bill of materials says what one yield of a product is made of. FourFoxes uses the active BOM for batch costing and for deducting packaging as batches are packaged. BOMs are admin-only.

  1. Open Supply Chain, then Bills of Materials, and click New BOM.
  2. Pick the Product, set the version and effective date, and enter the yield quantity and unit (grams or milliliters). All ingredient quantities describe this one yield.
  3. Add ingredient lines: the ingredient and the quantity required, in metric units.
  4. Add packaging lines: one component per line (a package type, closure type, or label type) and the quantity required per unit filled.
  5. Click Save BOM.

Versions. A product can hold many BOM versions, but only one is active. The active version is what costing and packaging deduction use. To change a recipe, Clone the current version, edit the clone, and click Set Active on it. The old version stays for history. The BOM page also shows a standard cost preview built from current weighted average costs, with the note that actual batch costs may differ.

Editing a costed BOM rewrites history's context

If a BOM version is linked to existing batch cost records, FourFoxes warns you before an edit. Prefer cloning to a new version over editing one that batches have already been costed against.
