# Do a stock take

Count what's really on the shelf or in a van and correct Sustainable ERP's numbers, with a reason kept for each change.

Use a stock take to set up opening stock, for a regular count, or when a van check finds a difference.

1. Open **Stock & purchasing** and select **Stock take**.
2. Choose the **Location** you're counting.
3. Enter a **Reason**, like "Monthly van check".
4. Search for each part you counted. **Held** shows what Sustainable ERP thinks is there.
5. Enter what you found under **Counted**.
6. Select **Save count**.

Each difference is recorded as an adjustment with your reason. You'll see them in **Ledger** and on each part's history. Parts you didn't count are left alone.

## Good to know

- Counts never go below zero.
- Nothing is deleted: the ledger keeps every change, and corrections are new entries.
- Counting a van? Ask the engineer to confirm any transfers on their way first, so they're included.
