How to Process an Order for Serial Number product in Odoo POS
Processing an order for a serial number–based product in Odoo POS requires proper traceability and validation to ensure accurate inventory tracking. Serial number products are handled differently from regular items because each unit must be tracked individually from purchase to sale.
Traceability in Inventory
When the product’s Traceability setting in the Product Master is configured as “By Unique Serial Number,” the system ensures that every unit is uniquely identified throughout the entire process. In POS, this means only one unit of a serial-numbered product can be sold per transaction line, which helps maintain complete accuracy in stock movement.
Starting the Serial Number Product Workflow in POS
When adding a serial number product to the POS cart, the system allows multiple methods such as entering the product code with a leading slash, scanning a barcode or EAN code, using multiple barcodes linked to the product, or scanning the lot barcode for tracked items.
Once added, the quantity automatically defaults to one because serial-numbered items can only be sold as single pieces. If the cashier attempts to increase the quantity, the system immediately blocks the action and shows a validation message, ensuring that no serial number is recorded more than once. This guarantees that every serial-numbered product is sold as an individual and traceable unit.
For each serial number product added to the cart, the selling price is displayed clearly, and the total amount always matches the price since the quantity is restricted to one. Some serial-based products may also follow MRP-based pricing.
In such cases, if the MRP differs from the selling price, the system automatically displays the savings amount. This provides transparency and helps customers understand any price reductions applied to their purchase.
Completing the Payment
After verifying all details on the screen, the cashier can proceed to payment by selecting a payment mode or pressing the shortcut keys. Once the preferred payment method is chosen, confirming the payment completes the order. The entire process ensures that the sale is correctly linked to the respective serial number.
Bill Receipt and Serial Number Details
Once the order is validated, the system generates an A4-size bill receipt containing all essential information. The product line displays details such as the HSN code, product name, salesperson (if added), quantity, and IMEI details.
Since serial-numbered products often include IMEI1 and IMEI2, both are shown on the invoice. If IMEI2 is not available, the system marks it as “/”. The pricing section of the receipt clearly displays the product’s MRP, rate, selling price, and any savings applied due to price differences.
All essential fields required for accurate billing and customer clarity are automatically included, making the invoice complete and easy to understand.
