What is stock control in simple terms?

Stock control, in simple terms, is making sure you have enough of what sells — and not too much of what doesn't. Too little and you lose sales to stockouts; too much and your cash sits on shelves aging instead of working. Everything in stock control serves that balance.

In practice it means four habits: knowing your real quantities (accurate records, ideally scan-based), knowing when to reorder each product (a reorder point based on how fast it sells and how long suppliers take), knowing how much to order (enough to last, not enough to gather dust), and reviewing the slow movers before they become dead stock.

Small businesses often run this on gut feel — which works until the product count or order volume outgrows one person's memory. The habits stay the same; the tooling grows up.
