The product
performance card.

The product performance card is where you discover which products are actually carrying your shop. Most owners think they know — and most are partially wrong. The card surfaces the real answer.

01 What it ranks

Every product you've sold in the range, ranked by total gross margin contribution. The card shows the top 5 by default, with an "expand" to see the full list. Each row shows the product name, units sold, gross margin, and a sparkline of weekly trend.

02 How to read the rank

• Top row — your hero product. The one paying the rent. Protect it.
• Middle ranks — solid contributors. Worth keeping prices honest on.
• Bottom ranks — low-volume or low-margin. Consider whether they're worth catalogue real estate.

03 Pitfalls to watch for

• Bottom-ranked staple. Sometimes a product with low margin contribution is what brings customers in (cheap coffee, loss-leader sandwich). Removing it could hurt the top product.
• Newly added product. A product set up last week always ranks low — not enough sales history. Wait two weeks before reading the rank.
• Archived product still listed. Archive removes from the picker but the card still shows historical contribution if it sold during the range.

04 Actions to take

Three patterns that follow from a product-performance read:

• Protect your hero. The top product is worth careful attention — don't risk supply issues, don't mess with the recipe, don't price it down.
• Investigate the underperformers. A long-tail product with low contribution may be wasting catalogue space. Or it may be the loss-leader that brings customers in. Look at the data; don't just cut.
• Test variants. If your hero is a cappuccino, what about an upgrade variant at €4,50 — would a fraction of customers take it and boost margin?
