Before starting, ensure that the products have already been assigned to a batch via a purchase order or inventory adjustment. **Note:** Access to batch and serial number tracking requires the **Xtra subscription** tier. ### Configuring your columns To see which batch number is assigned to a product, you must first ensure the correct column is visible in your transaction grid. 1. Open your sales order and click the **columns** tab on the right side of the screen. 2. Search for **item location** and check the box to activate the column. 3. Click the **columns** tab again to close the menu. ### Assigning a batch number Once your products are added to the order, you need to specify which batch the items will be pulled from. 1. Click the **more actions** arrow (green triangle) next to the primary action button. 2. Select **pick location**. 3. A window will appear showing the available stock locations and batches for the selected product. 4. Adjust the quantities in the far-right column: decrease the quantity from the general warehouse (**WH**) and increase the quantity for the specific **batch number** you wish to use. 5. Repeat this process for all relevant items and click the **accept** button (green checkmark). **Tip:** You can assign batch numbers at any stage of the order, even before the order confirmation has been sent. ### Finalizing the order After the batches are assigned, you can finalize the sales order following your standard workflow. This typically includes: - Generating a **packing slip** or **delivery note**. - Issuing the **sales invoice**. Paragon will now automatically deduct the stock from the specific batch and record the transaction in the product's history for full traceability.   - [Paragon Basics](https://support.paragon-erp.com/paragon-basics?hsLang=en#main-content) -
