## Related Concepts

Here are a few key concepts of TWICE Commerce that relate to Income & Expenses tracking.

  <Accordion title="Item-Level vs SKU-Level Tracking">
    Income and expenses aggregate per <Tooltip tip="A unique identifier that can represent a single item or a group of similar items" href="/docs/concepts/inventory/stock-codes" cta="Learn more">stock code</Tooltip>. For item-level profitability, assign each item a unique stock code.
