Lesson 6 · Learn
Revenue treats every dollar as equal. Profit does not. That single gap explains most of what is wrong in most of the businesses I am called into.

It counts a dollar from your best customer and a dollar from your worst as the same dollar. Profit knows the difference, and nobody looks at profit the same way.
In most industrial, manufacturing and distribution businesses, a minority of customers produce more than all of the profit, and the remainder consume part of it back.
It is normal to find that 15 to 25% of customers produce 110 to 130% of profit.
Above one hundred percent is not a typo, and it is the part people re-read. If a fifth of your customers generate 120% of your profit, then the other four fifths collectively generate negative twenty percent. They are not low-margin. They are taking money off the table your best customers put there.
The same pattern shows up in products, in locations, and in salespeople. The vital few carry the business; the trivial many consume it. Most reporting is built in a way that makes this invisible.
Where the loss actually hides
Not usually in price. Price is where everyone looks first, because price is visible and negotiable and easy to argue about.
It hides in cost to serve — what a customer actually costs you to keep. Small orders. Rush jobs. Changeovers. Custom specifications. Engineering revisions on work already quoted. Freight you absorbed. Expedites you did not charge for. And the planning and management attention that complexity quietly consumes, which never appears on any statement but is the scarcest thing you own.
A customer at a healthy headline margin can be your worst account once cost to serve is counted honestly. Several of them usually are.
Standard reporting allocates overhead evenly — as a percentage of revenue, or per unit, or per order. It is the one method guaranteed to hide this problem.
Complexity does not consume resources evenly. The customer who orders four times a year in full pallets and the customer who orders forty times a year in part cases with a custom label do not consume the same planning, warehouse and management capacity. Even allocation charges them the same and reports them as similar. Your own accounts are averaging out the very difference you need to see.
This is not an accounting failure. Standard costing was built to value inventory, not to tell you which customers to keep. It is doing its job. It is simply the wrong instrument for this question.
Every business I have run or been called into had a growth story. More customers, more products, more locations, more revenue. And in most of them, a large share of that growth had made the company harder to run and no more profitable.
So here is the sentence worth sitting with before the next lesson.
You have been buying complexity and calling it revenue. Lesson 7 checks whether that is true in your business, using your own customer list. It takes about twenty minutes and one export.
