Managing inventory effectively means having precise control over the movement, location, and status of each item. In industries such as electronics, food and beverage, pharmaceuticals, and manufacturing, batch numbers and serial tracking aren't just conveniences — they're necessities. Dolibarr ERP/CRM, known for its modularity and flexibility, offers robust features for batch and serial number management. If you're considering implementing or improving traceability in your inventory, this comprehensive guide will walk you through how Dolibarr can help.

What are Batch Numbers and Serial Numbers?

Before diving into the features, it's important to understand the difference:

• Batch Numbers: Identify a group of items produced or received together. Typically used for consumable goods, pharmaceuticals, or products with expiry dates.

• Serial Numbers: Unique identifiers assigned to individual items. Common in electronics, machinery, and high-value assets.

Both methods serve traceability, compliance, quality control, and warranty management.

Why Batch and Serial Tracking Matters

Implementing batch or serial tracking brings tangible benefits:

• Regulatory Compliance: Essential for industries with strict legal obligations (e.g., FDA, ISO).

• Quality Assurance: Track defective products back to the source.

• Inventory Accuracy: Monitor movements at a granular level.

• Customer Service: Easily manage returns and warranties.

• Risk Management: Simplify product recalls if necessary.

Dolibarr enables all of this through its integrated tracking system.

Setting Up Batch and Serial Tracking in Dolibarr

1. Enable Product Tracking

Navigate to:

Home > Setup > Modules > Products/Services

Activate the feature to manage products by lot or serial numbers.

2. Define Products with Tracking

When creating or editing a product:

• Set "Stock Managed" to "Yes."

• Enable "Manage Serial or Lot Numbers".

• Choose if you want:

  • One lot number for a set of items (batch tracking)

  • One serial number per item (serial tracking)

Add other relevant data such as:

• Expiry dates

• Manufacturing dates

• Supplier references

3. Configure Warehouses

Since batches and serial numbers are tied to stock movements, ensure you have your warehouse module activated and your locations properly set up.

Home > Products/Services > Warehouses

Create or edit your warehouses as needed.

Operational Use: Daily Activities

1. Stock Reception

When receiving stock:

• Record incoming quantities.

• Assign batch or serial numbers.

• Optionally add manufacture/expiry dates.

Each received unit or batch will now be traceable independently.

Example:

• Receive 500 units of Product X.

• Assign Batch Number "X-20240404" with expiry 2026-04-04.

2. Stock Transfers

When moving stock between warehouses, Dolibarr prompts you to select the batch or serial number involved.

Transfers maintain the full traceability history.

3. Customer Shipments

When shipping products to customers:

• Select the batch or serial numbers you are delivering.

• Keep complete records of which specific items were sent to which client.

This is invaluable for after-sales support, warranty claims, and product recalls.

4. Returns and Repairs

In the event of returns or warranty repairs:

• Identify the returned item by its serial number.

• Validate warranty eligibility by checking shipment dates and expiry periods.

• Track repaired or replaced items through new serial allocations if needed.

5. Stock Corrections and Inventories

During physical inventory:

• Count items by batch or serial.

• Easily identify missing, damaged, or expired products.

• Adjust quantities directly in Dolibarr.

Batch and Serial Tracking in Supplier and Customer Orders

1. Supplier Orders

When placing a purchase order:

• Indicate that items must be batch- or serial-tracked.

• Ensure suppliers provide the required batch/serial data on delivery.

You can enforce mandatory lot/serial recording upon goods reception.

2. Customer Orders

When creating sales orders:

• Reserve specific batch/serial numbers ahead of shipment.

• Guarantee FIFO (First In, First Out) or other stock movement strategies if required.

Dolibarr helps prevent accidentally selling expired, recalled, or reserved stock.
