Reduce Manufacturing Costs: Using Costing Methods & Serial Numbers Effectively

Why Are Manufacturing Costs in Odoo So Important?

In production, manufacturing costs are a key factor in determining profitability. Odoo allows you to track exactly what a product truly costs – taking into account materials, labor time, machine hours, and more.

The Manufacturing module enables precise cost calculation – provided the right settings are in place.

Which Costing Methods Are Available in Odoo?

Odoo offers several costing methods that support both classic standard costing and dynamic, real-time valuation based on actual data. The main costing methods include:

• Standard Costing (Odoo Standard Cost)

Here, you define fixed costs for materials, labor, and overhead. These values are then used to calculate manufacturing costs. This method is simple and transparent but can become inaccurate when market prices fluctuate.

• FIFO (First In, First Out)

Odoo supports the FIFO method, which assumes that the first items received are the first ones consumed or sold. This approach provides realistic cost tracking, especially for fast-moving products.

• AVCO (Average Cost / Weighted Average)

With this method, Odoo calculates a weighted average of all available purchase prices and uses it to determine manufacturing costs. It is a practical option when prices remain relatively stable.

The costing method is selected per product under Inventory > Products > Costing Method.

Important: Changes after production has started are only possible to a limited extent.

Perpetual Inventory Valuation & Real-Time Cost Control

One of Odoo’s key strengths is perpetual inventory valuation. All transactions – goods receipts, internal transfers, sales, and manufacturing orders – immediately affect cost accounting. This gives you an accurate, up-to-date overview of inventory and manufacturing costs at any time.

This real-time valuation enables precise control of manufacturing costs and timely analysis of production processes – a major advantage over static costing methods.

Serial Numbers & Manufacturing: Staying in Control

Serial numbers (and lots) are essential for high-value products or regulated industries. Odoo offers seamless integration of serial number management within manufacturing:

• Manufacturing with serial numbers
• Full traceability of every component through to the finished product
• Cost analysis per serial number

Activate this feature under Inventory > Configuration > Product Traceability to achieve maximum transparency in manufacturing costs.

Odoo for Manufacturing Companies in the USA

Thanks to its flexibility and cloud-based architecture, Odoo is ideal for manufacturing companies in the USA – from small businesses to mid-sized production companies. Particularly relevant features include:

• US GAAP-compliant cost accounting: Odoo can be configured to meet US accounting requirements and accurately report manufacturing costs.
• Integration with US supply chains: Odoo seamlessly connects shipping, warehousing, and manufacturing, even in multi-warehouse environments.
• Scalability: Its modular architecture supports growth and adaptation to more complex production processes.
• Serial number and lot tracking: A major advantage for regulated industries such as MedTech or food production.

This allows US manufacturing companies to keep manufacturing and production costs under control and optimize operations efficiently.

Additional Important Features for Cost Control in Odoo

• Cost capture: Odoo records all production-related costs – from materials and labor to overhead and subcontracting – enabling precise manufacturing cost calculation.
• Cost reports: Detailed reports provide insights into product profitability and manufacturing costs.
• Analytic accounting: Analyze costs across multiple dimensions, such as projects, departments, or customers.
• Preliminary costing: With add-ons like gio_preliminary_costing, you can create preliminary cost calculations and compare them with actual manufacturing costs for better budget control.
• Automation: Odoo can automatically generate accounting entries, reducing workload and minimizing errors in cost accounting.

Best Practices for Manufacturing & Production Costs in Odoo

• Choose standard costing for products with stable prices and simple production processes.
• Use FIFO or AVCO when material prices or inventory movements are more complex.
• Enable perpetual inventory valuation for real-time cost visibility.
• Use serial numbers to ensure traceability and precise unit-level cost analysis.
• Training for production and accounting teams is essential to fully leverage Odoo.
