## Update Stock Level
This option will allow you to enter the quantity you used of a material and have it deducted. This is how you can update a material individually.
1. On your left sidebar, select **materials** to access your list of materials.
2. Click on the **Stock Level** of the material you want to update.
3. Select **Product Testing** as your Update Stock Level type.
4. Add the quantity of the material you used for testing.
5. Click **Update**.
## Create a Production Run
With this option, the produced products will not go into your inventory, and will essentially just be discarded (as if you sent them directly to a wholesale customer).
1. From your dashboard, make sure you select **Production**.
2. In the upper-right-hand corner, select **New Production Run**.
3. Select **Fulfilling an Order** as your Production Run Type
4. Enter your **Production Details**.
5. Click **Save**.
