## How Stock Tracking Works
**Tracking on**
When **Track stock quantity** is on, totals update automatically: adding a product to an invoice reduces stock, editing the line updates the amount, and voiding or deleting the invoice restores it. You can also use Actions to add or remove stock to keep levels current.
Products list showing quantity in stock number when tracking is enabled.
**Tracking off**
When tracking is off, history still records events but totals do not change. The product shows **Unlimited** instead of a number, and **manual add stock and remove stock actions are unavailable**.
With tracking off, products show **Unlimited** instead of a stock quantity.
> **If you need to turn tracking back on for a product:**
>
> From **Actions**, choose **Edit product** and switch **Track stock quantity** to **On**. The quantity resets to 0. Set the current level with **Actions,** select **Add stock** so totals reflect what you have on hand.

## Automatic Adjustments
{% hint style="info" %}
**Note:**
The actions below are recorded in **Stock Adjustment History**. With tracking on, **Quantity in stock** updates automatically.
{% endhint %}
These updates happen automatically for you:
* Adding a product to an invoice reduces stock.
* Voiding or deleting the invoice restores stock.
* Editing the quantity on an invoice line adjusts stock accordingly.
***
## Manual Adjustments
{% hint style="info" %}
**Note:**
You can only add or remove stock when **Track stock quantity** is enabled.
{% endhint %}
### Add Stock
Increase a product’s stock level.
1. Go to the **Catalog** and select the **Products** tab.
2. Find the product and click **Actions**, select **Add stock**.
3. Enter **Quantity**, **Cost price**, and select a **Reason**.
1. (optional) **Save price for next time**: Tick to set this as the product's new default cost price. Leave unticked to apply it only to this adjustment.
4. Click **Save**, The product's **quantity** updates immediately (shown below), and the change appears in Stock Adjustment History.
**Common reasons:** New stock, Return, Adjustment, Other (add a comment).
***
### Remove Stock
Decrease a product’s stock level.
1. Go to the **Catalog** and select the **Products** tab.
2. Click **Actions**, select **Remove stock**.
3. Enter **Quantity** to remove and select a **Reason**.
4. Click **Save**. The product’s **quantity** **in stock** updates immediately (shown below), and the change appears in Stock Adjustment History.

***
### **Adjust stock**
If you recount your stock and there is a discrepancy, adjust the difference.
Use [**Add Stock**](#add-stock) to increase or [**Remove Stock**](#remove-stock) to decrease the quantity on hand. In the **Reason** field, select **Adjustment**. \
Example: System shows 50 in stock, you count 48 → Remove Stock, Quantity 2, Reason: Adjustment.
***
## Stock Adjustment History
Use history to audit stocktakes and investigate discrepancies.
A complete log of every change automatic (from invoices) and manual (add or remove). Shows what changed, when, and who made the change.
To access the stock adjustment history for a product:
1. Go to the **Catalog** and select the **Products** tab.
2. Open **Stock adjustment history** from the product’s **Actions** menu.
The history opens in a side panel showing the product name at the top.
The right side panel lists all changes. Select any entry to see full details.

## Frequently asked questions
When adding stock, when should I leave “Save cost price for next time” unticked?
Leave it unticked when you don’t want to change the product’s default cost price. For example:
* A one off supplier promotion or discount.
* A temporary surcharge such as rush shipping that should not become the baseline.
* A stocktake correction where you are fixing quantity only, not revising cost.
* A mixed purchase batch where this lot’s unit cost differs from the usual.
(Unticked means it applies only to this adjustment and is recorded in history. The product’s default cost price remains unchanged.)
What happens when tracking is off?
History still records events, but totals do not change. The product shows Unlimited instead of a number. Manual add or remove actions are unavailable while tracking is off.
What happens if I turn tracking back on later?
Instead of "Unlimited" being displayed as the quantity, the quantity resets to 0. Use Actions, select **Add stock** to set the current level.
What happens when my stock reaches 0?
You can continue to sell the product. Stock can go below zero, so the quantity shows as a negative number. This helps you see how many units you need to reorder to catch up. Example: If stock is 0 and you sell 3, the quantity becomes −3. Reorder at least 3 to return to 0.
