# Troubleshooting Stock and Inventory Update Triggers

If stock is not changing the way you expect with Automated Stock Update Triggers for WooCommerce, the most common cause is a section that is off. Both Decrease Stock and Increase Stock are off by default, so go to WPFactory > Stock Triggers, turn on Enable section for the one you need, select your triggers, and save.

### Stock is not adjusting at all

1. **Is the plugin enabled?** Check that **Enable plugin** (`alg_wc_stock_triggers_plugin_enabled`) is on under **WPFactory > Stock Triggers** (also reachable at **WooCommerce > Settings > Stock Triggers**).
2. **Is the section enabled?** Both Decrease Stock and Increase Stock are off by default. Turn on **Enable section** for the one you need and save.
3. **Is the right trigger selected?** Confirm the order event you rely on (for example Completed, or Payment complete) is chosen in the **Triggers** list for that section.
4. **Does the order actually reach that status?** If you selected Processing but your workflow jumps straight to Completed, the trigger never fires. Match the trigger to the statuses your store really uses.
5. **Turn on Debug.** In the Admin sub-section, enable **Debug** and reproduce the order. The log at **WooCommerce > Status > Logs** (source `stock-triggers`) shows which trigger fired.

### Stock changes for some orders but not others

- **Require products / Require product categories:** if either is set, every item in the order must match your selection. An order that also contains a non-selected product will be skipped. Clear these fields to remove the restriction, or review [how the matching works](/docs/woocommerce-stock-triggers-require-products-categories/).
- **Increase only restores what was decreased:** increase cannot raise stock above the quantity that was previously reduced for that order.
