# Investigate waste, idle stock, and sold-out events

**Reports → Inventory reports.** Choose the location and period before comparing
stock and menu availability.

| Report       | Read it as                                                                         |
| ------------ | ---------------------------------------------------------------------------------- |
| Waste        | Recorded waste quantity/value, reasons, items, and change from the previous period |
| Dead Stock   | Items matching the selected low-movement threshold and period                      |
| Stock health | Recorded stock against configured pars and estimated usage cover                   |
| Auto 86      | Automatic sold-out events and recovery status, with estimated lost sales           |

No waste records do not prove nothing was wasted. Keep recording through
[Waste and returns](/stock/waste). Staff meals and cancellation comps can be
shown separately; a comp discount on a paid bill is not the same record.

A dead-stock result depends on the selected movement threshold and time window.
Check physical quantity, counted coverage, and missing movements before making a
disposal or transfer decision. Days on hand is based on recent usage; an item
with no usage in that window needs review rather than a guessed consumption
rate.

Stock health covers items with pars set. **Nothing under par** is not proof that
every catalogue item was counted or has a suitable par. Check
[Stock levels](/stock/levels) and opening coverage.

Auto 86 follows service countdown availability. Ingredient consumption/cost
alone does not establish a sold-out service count. Estimated lost sales are not
orders that were actually placed. Inspect
[Menu countdowns](/guides/item-countdowns-auto-86) and manual holds before
changing availability.

If a result is missing or surprising, check filters and source records first.
Escalate with location, period, item/unit, physical result, recorded movement or
event, and the exact warning/error.
