Every guide, in one list

Stock records do not drift because people are careless. They drift because a dozen ordinary events each move stock without moving the record.

Counting everything once a year is the most disruptive and least useful way to find out what you have.

Stock work often confuses doing more with removing wasted effort. For a broader comparison of output and efficiency, see this overview.

Most accuracy figures are calculated in the way that produces the highest number.

The labour in stock control is invisible because nobody records it, which is why the expensive option keeps being chosen.

A correct quantity in an unknown location is functionally out of stock, and it is the most common hidden cost in small storerooms.

Damaged and expired stock disappears quietly in most small businesses, taking the evidence of why it happened with it.

For broader operational context for small businesses, the U.S. Small Business Administration provides public management resources.

Most reorder points are a level someone felt comfortable with. The calculation is not difficult and produces a different answer.

The lead time in your system is the one the supplier quoted when the account was opened.

Safety stock is set by temperament: cautious people carry too much, optimistic people run out. Neither is a calculation.

The reorder point says when. Order quantity says how much, and it is usually set by whatever the supplier's price break happens to be.

An unreliable supplier is paid for in the stock you carry to cover them, which never appears on their invoice.

Without a number, stockouts are treated as unlucky. With one, they become a comparison against the cost of carrying more.

Signing for a pallet without counting it transfers the supplier's error onto your stock record, permanently.

Most small businesses find discrepancies and never claim them, because the process for claiming is more effort than the amount involved.

Receiving is treated as an interruption rather than a process, which is why it is understaffed on exactly the days it is busiest.

A delivery that is complete and damaged has been received correctly and is still a loss.

Customer returns are the most common way stock records gain phantom quantities that are not there.

Consignment, customer-owned materials and goods on approval sit on your shelves and belong on nobody's stock record by default.

Shrinkage is usually described as theft and is usually mostly paperwork.

Obsolete stock is the least urgent problem in any storeroom and one of the most expensive.

First in, first out is a slogan until the newest delivery is put in front of the older one.

Stock value affects profit, tax and borrowing, and the method used is frequently whatever the software defaulted to.

Samples, demonstrations, repairs and staff purchases move stock without a sale, and are the quietest source of record drift.

A shrinkage investigation handled badly costs more in goodwill than the stock was worth.

No stock system works on top of inconsistent item codes, and no migration fixes them.

A spreadsheet runs stock control for longer than vendors suggest. The thresholds that force a change are specific and worth waiting for.

Scanning removes a category of human error entirely. The question is whether that error is currently costing you enough.

Most stock systems are built for warehouses. A business with a storeroom needs a fraction of it and pays for the rest in configuration.

Stock systems produce dozens of reports and most businesses look at none of them regularly.

In most small businesses stock is everybody's job, which means it is nobody's, and the record decays accordingly.
