1. The licence and the pharmacist
A retail drug licence is required, and it generally requires a registered pharmacist along with premises meeting specified conditions including area and storage such as refrigeration. The application goes to the state drugs control authority, and the requirements vary by state. This is the part to get professional help with rather than working from a general article, because operating without a valid licence is a serious matter rather than a compliance oversight.
2. Batch and expiry are the whole discipline
Medicines expire, and expired stock is a liability rather than an asset. Recording batch and expiry against what you buy and sell is what lets you return near-dated stock to the supplier in time, respond to a recall, and answer an inspection. None of it can be reconstructed later. The figure to review monthly is the value of stock within ninety days of expiry — that is the difference between a return and a write-off.
3. Margins are set, so stock discipline is the business
Retail margins on medicines are largely determined by the printed price, which means you do not compete on rate. What you compete on is availability — a customer who does not find their medicine goes elsewhere and often does not come back. That makes fast-line stock accuracy and reordering the actual skill in this trade, and both depend on stock moving from billing rather than from a register.
4. Packs, strips and loose sale
Medicines sell as a full pack, a strip or loose tablets from the same stock, and the rate per unit differs across pack sizes. Holding the conversion on the item means the stock figure stays correct however the sale is made. Barcode scanning on the fast lines keeps a busy counter moving, which matters because pharmacy counters queue at predictable times.
5. Credit for clinics and families
Many medical stores carry regular families and nearby clinics on monthly accounts. Those are worth having and worth recording properly — set a limit, let the ledger build from the billing, and send a statement at month end. Clinic accounts in particular can grow quickly, because the volume is steady and nobody totals it until settlement.
6. What to get right before opening
Licence and pharmacist first, then premises and storage including refrigeration, then GST registration, then supplier arrangements with the distributors serving your area. Establish your batch and expiry recording from the first purchase rather than adding it later, because retro-fitting that discipline onto existing stock is genuinely difficult.
