Inventory & Stock Tracking

Understand stock maintenance, low stock alerts, batches, expiry, serials, variants, and transfers.

Stock Maintenance

When Track Inventory Stock is ON, billing validates available quantity and deducts stock after invoice save.
When OFF, stock enforcement is disabled and billing should not reduce inventory.
Use stock transfers to move goods between stores or branches.

Batch and Expiry tracking is useful for pharmacy, FMCG, and food businesses.
Serial, IMEI, and warranty tracking is useful for electronics and mobile stores.
Variants help garment businesses manage size, color, fabric, and style.
Jewellery fields support gross weight, purity, stone weight, making charges, and HUID.

Use Batch Number Tracking when each stock lot needs a unique batch or lot code, such as Pharma Lot, FMCG lot, food batch, or cosmetics batch.
Example: Paracetamol 500mg can have LOT-001 with quantity 50 and LOT-002 with quantity 50, so stock remains traceable batch-wise.
Batch tracking helps with product recalls, supplier traceability, purchase history, stock movement, and expiry-based stock control.
When this setting is ON, batch number should be required during Stock In or Purchase Bill entry for batch-tracked products.

Use Expiry & Mfg Date tracking when products have manufacturing and expiry dates.
FEFO means First Expiry, First Out: the system should suggest or consume the batch with the earliest valid expiry date first.
Example: if LOT-001 expires on 10-Jan-2026 and LOT-002 expires on 10-Mar-2026, sales should pick LOT-001 first.
Expiry date should be required when expiry tracking is enabled, and expiry date must be after manufacturing date.

Enable Batch Number Tracking and Expiry & Mfg Date in Settings > Item Settings, then save settings.
Create or edit one product and enable batch and expiry tracking for that product.
Stock In the same product twice: LOT-001 quantity 50 with earlier expiry, and LOT-002 quantity 50 with later expiry.
Open product details or stock report and confirm both batches show separate available quantities.
Create a sale for the product and confirm the earliest non-expired batch is selected first by FEFO.
Try invalid cases: missing batch number, missing expiry date, expiry before manufacturing date, and expired stock selection. The system should warn or block based on the business rule.
After saving the sale, verify stock reduces from the selected batch only.
