How to Manage Batch-Wise Medicine Inventory

A medicine is rarely a single stock item. The same tablet can sit on your shelf in three batches, bought on different dates, at different rates, with three different expiry dates. If you only track "Paracetamol 500 mg: 120 strips", you lose the detail that matters most.

What is a medicine batch?

A batch (or lot) is a quantity of a medicine manufactured in one production run. The manufacturer prints a batch number on the pack, along with the manufacturing and expiry dates. Every unit in a batch shares the same expiry date.

Why is batch-level stock tracking important?

Tracking by batch gives you answers that a single total cannot:

• Which stock expires first? You can sell first-expiry-first-out (FEFO) with confidence.
• How much stock is at risk? You can see the quantity and value of each batch nearing expiry.
• Where did this come from? You can trace a batch back to the supplier and invoice it arrived on.
• What should we do if a batch is recalled or questioned? You can find exactly which batch you hold and how much of it.

Without batch records, expiry checks become a manual hunt through shelves.

What information should be recorded for each medicine batch?

At minimum, record these fields for every batch you receive:

Some pharmacies also record the manufacturing date and storage notes, for example for refrigerated items.

How to set up batch-wise inventory: step by step

1. Start with fast movers. Do not try to convert your whole store in a day. Begin with the 50–100 items you sell most.
2. Count by batch. For each item, separate the physical stock by batch number and count each batch.
3. Enter each batch separately. Record the fields above for every batch, even if the medicine name is the same.
4. Receive all new stock by batch. From now on, every purchase entry includes batch and expiry.
5. Bill from the right batch. At the counter, sell the earliest-expiring batch first. Good software can help by showing batch details.
6. Review weekly at first. Check that system quantities per batch match the shelf for a sample of items until the process is reliable.

Common mistakes to avoid

• Merging batches because the medicine name is the same. This hides expiry risk.
• Typing errors in expiry dates, such as entering the manufacturing date in the expiry field. Double-check at entry.
• Skipping returns and adjustments. If damaged or expired stock is removed physically but not in the records, batch quantities drift.
