For your Odoo Inventory customization, I would implement the discount as a dedicated serial-number rule rather than modifying stock valuation directly. This keeps the inventory workflow stable while allowing the discount to follow the selected lot or serial number into the relevant sales or invoice line. I would first confirm where the discount should apply, such as quotation, sales order, invoice, or internal stock valuation, then build a custom Odoo module with configurable fixed-percentage discount rules mapped to unique serial numbers. The module can include serial lookup, validation to prevent duplicate or conflicting rules, automatic discount application, permission controls, and audit visibility for administrators. I would also test the flow across product reservation, delivery, invoicing, returns, and serial reassignment to ensure the customization does not interfere with standard Odoo inventory behavior. I handle custom business-system work end to end, including workflow analysis, module development, database changes, testing, deployment, documentation, and handover. A relevant example is HustlerGuys CRM, where we implemented custom operational modules covering invoicing, automation, time tracking, WhatsApp integration, and role-based workflows. Estimated timeline: 5–8 working days for a standard implementation, including testing and documentation. This may vary if the discount must also affect valuation, accounting entries, or multiple companies

Serial-number discounts in Odoo don't live in the Inventory module itself - the hook is a custom lot_id onchange on sale order lines that reads a percentage field stored on stock.lot. I'll write a small module to do exactly this: assign a fixed discount per serial number and auto-apply it when the lot is selected on a sale line. Happy to share similar Odoo work in chat. Two to three days to deliver. 1) Which Odoo version are you on - Community or Enterprise? Cheers Shayan

Hi, there. I have experience customizing ERP systems, developing Python-based business logic, and modifying inventory workflows to match specific operational requirements. I understand the importance of keeping inventory processes accurate while adding custom rules without affecting existing Odoo functionality. For your project, I can customize the Odoo Inventory module to support percentage-based discounts linked to unique serial numbers. I will review the current inventory flow, implement the required discount logic, and ensure the changes work correctly with stock movements, product records, and sales processes. The customization will be structured cleanly so it remains maintainable and compatible with future Odoo updates. I focus on reliable ERP solutions where data accuracy and smooth workflows are the priority. One question: should the serial-number-based discount apply automatically during sales orders, inventory valuation, or both areas? Thank you, Jaroslav Caprata

I can implement this customization in Odoo Inventory with a focus on keeping the discount logic reliable, maintainable, and fully integrated with existing stock workflows. From your description, the key requirement is associating fixed percentage discounts with products through unique serial numbers while preserving normal inventory operations. The best approach is to extend the Inventory models and validation flow so the discount is automatically applied whenever a serial-controlled item is selected or processed. This avoids manual handling and keeps behavior consistent across stock movements and sales-related operations. The implementation can include: - Serial number based discount rules - Automatic discount calculation during inventory/sales flow - Validation to prevent invalid serial usage - Clean integration with existing Odoo workflows and views - Testing to ensure no regression in stock operations I have strong experience working with backend customization, business rules, APIs, and scalable system integrations, which is important for Odoo modules that directly affect inventory consistency. If you already have a specific workflow in mind (purchase, stock transfer, POS, or sales order integration), I can adapt the customization accordingly. I can also help structure the solution so future discount rules remain easy to extend.

Hi, I can customize the Odoo Inventory module to support serial number-based discounts while keeping the standard inventory workflow intact. Here's how I would approach it: Add a discount field (fixed percentage) linked to individual serial numbers (lots). Automatically apply the discount whenever a serialized product is selected in a sale, transfer, or other configured workflow. Ensure the logic integrates cleanly with existing Odoo Inventory and Sales processes without affecting non-serialized products. Provide a flexible solution that allows discounts to be managed directly from the serial number record. I have experience customizing Odoo modules, including Inventory, Sales, access control, workflow automation, and custom business logic. Recently, I implemented custom security rules in Odoo to restrict product cost editing and have developed several inventory-related customizations. Estimated timeline: Analysis & design: 0.5 day Development: 2–3 days Testing & deployment: 1 day Total: approximately 3–4 business days, depending on your Odoo version and any additional workflow requirements. I'd be happy to discuss your specific workflow and provide a solution that fits your business needs.
