# Which of your items actually make money, not which ones sell

_Your best-selling product and your most profitable product are usually not the same thing, and the gap between them is where a shop's real earnings hide._

## In short
- Ranking by sales tells you what is busy. Ranking by profit tells you what is working.
- None of this exists without a cost price on the product. That one field unlocks the whole question.
- A low-margin item that brings people in is doing a job. Just make sure you know it is doing that job and not another.
- Look at the shelf space, not only the item. Slow money in a large space costs more than the item's margin suggests.

Ask a shopkeeper which product does best and you will usually get the fastest mover — the thing that goes out of the door most. It is a completely reasonable answer to a different question. What sells most and what earns most are two separate rankings, and in most shops they are close to reversed.

_[Figure: Same four items, two rankings. The item at the top of one list is at the bottom of the other, which is the entire point of looking at both.]_

### Why the fast movers earn least

The items that sell fastest tend to be the ones every shop within a mile also stocks, in packaging your customers recognise, at a price they broadly know. All three of those facts push the margin down. Cold drinks and well-known branded goods are the classic case: high turnover, low margin, and a price you cannot move because the customer knows it.

The money more often sits in things that are less visible — household items, loose goods, anything where the customer has no reference price in their head. Those often sell a fraction as often and contribute several times as much per sale.

**None of this works without cost prices.** Every one of these questions depends on the app knowing what you paid. If cost price is blank, the reports can only rank by revenue, which is the ranking you already had. If you do nothing else after reading this, put cost prices on your top thirty items — it is an hour that changes what the software can tell you.

### The four groups

|  | Sells a lot | Sells little |
| --- | --- | --- |
| Good margin | Your best items. Protect them: never out of stock, always visible. | Quiet earners. Worth a better position on the shelf — often they sell little because nobody sees them. |
| Poor margin | Draws people in. Fine, if that is the job it is doing. Check whether it actually is. | The problem group. Taking up space and money and returning neither. |

The bottom-right box is where most shops find something surprising. Items that sell rarely and earn little tend to survive because nobody has ever looked at them as a group — each one individually seems harmless.

### The thing the report does not show: space

A product report ranks items. It does not know that one of them occupies a quarter of a shelf and another occupies a hand's width. Two items earning the same amount per month are not equally good if one takes six times the room.

You do not need to calculate this precisely. Walking the shop with the profit ranking open and asking "is this thing earning its space?" catches nearly everything a formal calculation would, and takes twenty minutes.

**Check the loss-leader is actually leading.** The argument for a low-margin item is that it brings people in who then buy other things. That is often true and occasionally a story. If you can see customer-wise sales, look at what people who buy that item also buy. If the answer is nothing, it is not a loss leader — it is just a loss.

### What to do with the answer

- Move the quiet earners to where people look. Position is the cheapest change available to you.
- Never run out of the fast, high-margin items. A stockout there costs you more than anywhere else in the shop.
- Stop reordering the bottom-right group, or cut it to a token quantity. Do not clear it in a dramatic gesture; just stop replacing it.
- Leave the deliberate loss leaders alone, once you have confirmed they are doing the job you think they are.

> Turnover is what a shop looks like from outside. Margin is what it feels like at the end of the month.

## Common questions

**How do I find out which products are most profitable?**

You need a cost price recorded against each product; with that, product-wise reporting can show margin rather than just revenue. Without cost prices the app can only tell you what sold, which is the less useful of the two answers.

**Why is my best-selling item often not my most profitable?**

Because the things that sell fastest are usually the things everybody stocks, and everybody stocking them is what pushes the margin down. Well-known branded goods at a familiar price are often close to break-even; the money tends to sit in items customers cannot price-check at a glance.

**Should I stop selling low-margin items?**

Not automatically. Some low-margin items are why customers walk in at all, and losing them costs you the visit rather than just the item. The distinction worth drawing is between a low-margin item that pulls people in and a low-margin item nobody comes for — the second one is simply taking up space.

**How often should I look at this?**

Once a quarter is enough for most shops. It is a decision-making view rather than an operational one, and looking at it monthly tends to produce reactions to noise rather than to real changes.
