Inventory management for small businesses: 9 practical tips

Updated 22 October 2026 · 5 min read

Most stock problems in small businesses come from a few habits. Fix these and you will run out less, waste less and know what your stock is really worth.

Nine habits that keep stock under control

  1. Give every item one name and one code. Duplicate names ("Shirt blue", "Blue shirt") are where counts go wrong.
  2. Record stock the moment it moves — on receipt, sale, transfer or return — not at the end of the day.
  3. Set a reorder level for your fast movers: how many you sell while a new order is on its way, plus a small buffer.
  4. Sell the oldest stock first (FIFO), and for anything with an expiry date, track batches.
  5. Count a little every week (cycle counting) instead of one painful annual count.
  6. Write a reason against every adjustment — damage, theft, sample, counting error — so patterns show up.
  7. Look at what has not sold in 90 days. That money is tied up; a discount or bundle often frees it.
  8. Keep stock by location if you have more than one shop or warehouse, so a "missing" item is not just in the other branch.
  9. Use the same system for billing and stock, so a sale can never be recorded without the stock going down.

A quick reorder-level example

If you sell 20 units a week and your supplier takes one week to deliver, reorder when stock falls to about 20 units, plus a buffer of, say, 10 — so a reorder level of 30.

Common questions

What is a good reorder level?+

Roughly what you sell while a new order is on its way, plus a safety buffer. Review it when sales change.

What is FIFO?+

First in, first out: sell the oldest stock first. It matters most for anything that expires.

How often should a small business count stock?+

Count a few items every week (cycle counting) so every item is counted several times a year without closing the shop.
