[ The worked case ]
The situation
Kiln & Pine is an invented store: a one-person ceramics studio in Porto that opens the shop at eight and the numbers at nine. July 2026 closes at €2,521. Nothing in that figure says that on four days the store spent €105 on ads — more than three times its usual day — and on two of them lost money.
The four push days
| Day | Taken | Ads | Kept |
|---|---|---|---|
| 6 Jul | €294 | €105 | €33 |
| 12 Jul | €172 | €105 | −€31 |
| 19 Jul | €231 | €105 | €1 |
| 26 Jul | €138 | €105 | −€47 |
| The four days | €835 | €420 | −€44 |
Over the other 26 days the store kept €2,565. Over the four push days, −€44. The ad line is the one that moved; the taxes, the goods and the fees followed the sales as they always do.
Each day’s costs are the month’s totals shared out by that day’s sales, so the thirty days add to €2,521 exactly. Demo figures.
What the morning brief says
On the day after 26 Jul, the brief arrives on Telegram before the shop is opened: what the last day kept, how it compares, and — in a line of its own — that 26 Jul went red at −€47, with ads at €105 on €138 of sales named as the cause.
The one thing worth doing
Under the brief sits one move, ranked in money a month, with its evidence attached. For this store it is: raise prices by 5%, worth €310 a month, projected.
| Evidence | |
|---|---|
| Revenue ex-VAT | €6,344 |
| Added at +5% | €310 |
| Current margin | 31.8% |
Revenue × 5%, less the payment fee that scales with it. Volume held constant. Its confidence is printed as low and its risk as high, and the card says why: Nothing here measures how many customers a 5% rise would cost you. The arithmetic is certain; the assumption that nobody leaves is not. Losing more than 5% of orders makes this worse than doing nothing. Nothing changes until the owner approves it.
