In logistics, order picking is one of the most crucial processes. It affects not only customer satisfaction but also the efficiency of inventory management and the associated costs. The removal strategy, or the choice of the order in which products leave the warehouse, is a key step in optimizing logistics flows. Depending on the nature of the products and the company’s needs, different removal strategies can be adopted to achieve specific goals.
Modern warehouse management systems, such as Odoo, offer various picking methods such as FIFO (First In, First Out), LIFO (Last In, First Out), FEFO (First Expired, First Out), and others. Each method has its advantages and meets specific needs. Here is a guide to understanding and choosing the best picking strategy for your activities.
Picking Strategies Available in Odoo
Odoo offers several standard picking methods, allowing companies to choose the strategy that best fits their products and objectives.
1. FIFO (First In, First Out)
Description: The FIFO method, or "First In, First Out", gives priority to the oldest items in stock for order picking. It is particularly useful for perishable or time-sensitive products, to limit losses due to expiry.
Main use:
- Industries: Food, pharmaceutical.
- Advantages: This method is ideal for optimizing stock rotation and avoiding waste of products with a limited shelf life.
Example: In a fresh-produce warehouse, vegetables and dairy products are shipped using FIFO logic to guarantee freshness to customers.
2. FEFO (First Expired, First Out)
Description: FEFO, "First Expired, First Out", is based on product expiry dates. This strategy ships the items with the nearest expiry dates first.
Main use:
- Industries: Food, chemicals and pharmaceuticals.
- Advantages: By automating the removal of products according to their expiry date, Odoo helps reduce losses from expired products and guarantees the quality and compliance of delivered products.
Example: In a pharmaceutical warehouse, medicines with the nearest expiry dates are shipped first to avoid scrapping products.
3. LIFO (Last In, First Out)
Description: The LIFO method, or "Last In, First Out", favors shipping products most recently added to stock. It is less common in industries where products have a limited lifespan.
Main use:
- Industries: Temporary stock, seasonal products.
- Advantages: LIFO avoids moving old items in stock and is convenient for non-perishable items.
Example: A building materials warehouse uses LIFO to ship the most recent materials first, thereby reducing handling.
4. FIFO by Batch
Description: This method applies FIFO logic but by lot or serial number, allowing items to be shipped according to their order of entry by production group.
Main use:
- Industries: Manufacturing, cosmetics, traceable products.
- Advantages: By using FIFO by batch, Odoo guarantees perfect product traceability, facilitating recalls and quality follow-up.
Example: In a cosmetics workshop, products are stored and shipped by production batch to ensure efficient handling in the event of a product recall.
Other picking strategies
Some specific logistics environments use removal methods that are not natively included in Odoo but can meet particular needs. These strategies can be handled by advanced warehouse management solutions or by customizing Odoo.
1. HIFO (Highest In, First Out)
Description: The HIFO method, or "Highest In, First Out", ships the highest-cost items first. This strategy is often used for high-cost products whose prices fluctuate.
Main use:
- Industries: Electronic components, precious materials.
- Advantages: Minimizes the average cost of remaining inventory by shipping the most expensive products first.
Example: An electronic components warehouse prioritizes shipping the most expensive items, thereby optimizing the capital tied up in stock.
2. LOFO (Lowest In, First Out)
Description: LOFO, or "Lowest In, First Out", consists of shipping the least expensive products first, leaving higher-value items in stock.
Main use:
- Industries: Products with price fluctuations.
- Advantages: This method can keep higher-value items in stock for future valuation.
Example: A seasonal products warehouse ships the cheapest items first to reduce storage costs.
3. Pick-to-Clear
Description: This method, "Pick-to-Clear", favors slow-moving or end-of-life items, thereby freeing up space for higher-demand products.
Main use:
- Industries: Sectors with end-of-season or end-of-life items.
- Advantages: Quickly frees up warehouse space and optimizes the handling of seasonal or promotional products.
Example: A fashion retailer uses Pick-to-Clear at the end of the season to ship winter items and free up space for the spring-summer collection.
Conclusion
Picking strategies allow companies to better organize their logistics flows according to their inventory management goals, their industry and the nature of their products. Odoo offers several standard methods (FIFO, FEFO, LIFO and FIFO by batch) suited to perishable products, traceable items and fast-moving products. For more specific needs, such as high-cost products or end-of-life items, strategies such as HIFO, LOFO and Pick-to-Clear are commonly applied in unique logistics contexts.
By combining a suitable picking strategy with modern warehouse management tools such as Odoo, companies can not only optimize their inventory but also reduce costs, minimize the risk of losses and improve customer satisfaction. Adapting the removal strategy to the nature of the products and the company’s objectives is therefore a powerful lever for efficient and sustainable inventory management.
