How to manage inventory for a small business (simple stock system)

Too much stock ties up cash; too little loses sales. A simple inventory system tells you what to reorder and when, without guesswork or midnight spreadsheet sessions.

Step 1: List every item with opening stock

Create a master list with item name, code or HSN, purchase cost, selling price and current quantity. This is the foundation for everything else.

Step 2: Record stock in and stock out

Every purchase adds stock; every sale removes it. When billing and inventory are linked, selling an item drops its count automatically, so your numbers stay live.

Step 3: Set reorder levels

For each fast-moving item, set a minimum quantity. When stock falls to that level, reorder. This prevents stockouts on your best sellers.

Step 4: Run a monthly stock audit

Once a month, physically count and compare to the system. Investigate gaps; they reveal theft, breakage or billing errors early.

Step 5: Clear dead stock

Flag items that have not moved in 90 days. Discount or bundle them to free the cash they are locking up. Dead stock is money sitting on a shelf.
