# Stock Ledger

> The complete, permanent, append-only history of every stock movement.

The **Stock Ledger** is the full audit trail behind every number in [Stock Balances](/retail/stock-balances) — every single stock movement, ever, in order, and it's never edited or deleted, only added to. If you ever need to answer "what exactly happened to this product's stock over time," this is where you look.

## Frequently Asked Questions

<AccordionGroup>
  <Accordion title="Can I edit or delete a ledger entry?">
    No — the ledger is append-only by design, so it's always a trustworthy audit trail. To correct a mistake, cancel the document that caused the wrong entry (which posts a reversing entry) rather than trying to edit history.
  </Accordion>

  <Accordion title="Every document type shows up here?">
    Yes — Goods Receipts, Purchase/Sales Invoices, Stock Adjustments, Stock Transfers, and Stock Count variances all post here, since they're all ways stock quantity can change.
