Items are the raw materials your recipes are built from: beans, milk, cups, lids, syrups, sugar. Each item carries a pack price and a yield %, and the app computes a per-unit cost from those two numbers.Documentation Index

What you fill in per item
Pack size, pack price, and yield. That’s it.Example: items for a Hot Coffee Latte
Throughout the docs we use Hot Coffee Latte as the running example. It’s built from three items:| Item | Pack size | Pack price | Yield | Computed unit cost |
|---|---|---|---|---|
| Whole milk | 1,000 ml | RM 8.00 | 100% | RM 0.008 / ml |
| Coffee beans | 1,000 g | RM 80.00 | 90% | RM 0.0889 / g |
| Paper cup | 1 cup | RM 0.30 | 100% | RM 0.30 / cup |
Yield matters when waste is real. Coffee beans usually waste ~10% to grind and spillage. Set yield to 90% and the app applies the waste to your COGS automatically — every recipe that uses those beans pays the inflated unit cost, so a “cheap” bean with 70% yield can quietly cost more than a premium bean at 95%.
Where items show up
- In every Recipe you build — each recipe line is
{Item, quantity}, and the app sums the line costs to give you per-cup COGS. - In the Calculator’s recipe-derived target line, indirectly: average COGS across recipes is what pushes the suggested price up or down.
