BOM cards (bills of materials)

A BOM card is the recipe for something you make — what materials and/or components go into it, in what quantity, and what it costs. Find them under BOM Cards.

BOM cards list

Product cards vs. item cards​

  • A product card is a sellable finished good.
  • An item card is a component or semi-finished part used inside other cards (mark a card as a component with the "is item" toggle).

A product's composition can reference both materials and other item cards, so multi-level BOMs (a product made of components, each made of materials) are supported.

Composition​

Each composition line has:

  • A material or a component item
  • Quantity needed per unit produced
  • A loss coefficient (1.0 = no loss; higher values account for technological waste, e.g. trimming or shrinkage)
  • An optional manufacturing step label (e.g. "cutting", "sewing", "finishing")

Versions​

BOM cards are versioned. Once a version has been used in actual production, its composition and key fields lock — create a new version instead of editing it, so historical production records keep referencing the recipe that was actually used at the time. You can compare any two versions side by side to see exactly what changed (materials, quantities, prices, margin).

Costing​

  • Other expenses — fixed monetary costs per unit, or a percentage of cost / of final price (e.g. packaging labor, marketplace fees)
  • Postal materials — shipping/packaging materials per sales channel, pulled from material stock but kept separate from the product's own composition
  • Prices & margin — per sales channel, showing cost + other expenses + postal materials + channel commission, so you see real margin per channel, not just list price
  • Material requirements — click Calculate to see exactly how much of each material is needed per unit, losses included

Composition diagram​

The Diagram button on the card page - and the diagram icon in the row actions on BOM Cards, Ready Items and Finished Goods - opens the whole recipe as a picture: materials on the left, the items they build in the middle, the finished product on the right, and packaging per sales channel in a band below.

Composition diagram of a product, from materials to the finished unit

  • Everything is per one unit. Each box shows the quantity and the cost that goes into a single product, so the diagram and the card's cost tell the same story. Other expenses (labour, overhead) appear as boxes without a quantity.
  • The material that runs out first is highlighted in orange. Hover any material to see how much is available and how many products that covers - that is the one limiting your next batch.
  • Click an item or product box to open its card. Hovering an item also shows which version of it this recipe uses, and warns you when that is no longer the current version.
  • Navigation. Hold the right mouse button to move the diagram around, Ctrl + wheel to zoom, or use the zoom / fit buttons in the top right.
  • Arrange it. Drag boxes and connecting lines to lay the diagram out the way you think about the product, and double-click one to put it back. The arrangement is saved per product for the whole workspace, so everyone sees the same picture. Viewing and arranging are separate permissions, so a role can be allowed to look without being able to rearrange.

If the card's cost differs from the sum in the diagram, the diagram says so: it adds up material costs down the whole chain, while the card prices a component that is already in stock from its own production batches.

Descriptions & photos​

Each product card can have a description and multiple photos, with one marked as primary. These feed the product cards your team sees in the app and are also what gets synced to Shopify if Shopify sync is enabled for product data and photos.

Import/export​

BOM cards (both product and item cards) can be bulk-imported or exported via Excel.
