- Small makers selling component-based products across channels
- Worth noticing
- Builds are deliberately one level deep; self-made components such as a 3D-printed body do not count as inventory parts.
Field notes
The example inventory calculates capacity from component stock and identifies a 6 × 3 mm neodymium magnet as the limiting part. The site says paid orders reduce parts across shared-SKU listings, while cancellations and refunds put them back. Its stated scope is intentionally narrow: one-level product recipes, with warehouses, dropshippers, and nested assemblies excluded.
