Offer add-ons that add profit.
Add-ons that fit the product, are in stock and protect margin, judged on profit per visitor.
| Add-on | Rule | Status |
|---|---|---|
| Care Kit | Fits canvas, margin above the floor | Offered |
| Merino crew | Pairs with every jacket | Offered |
| Trail pant | Under 21 days of stock | Held |
| 10% off a second jacket | Lowers contribution | Off |
The rules for one jacket. Merchandising owns every line.
Sound familiar?
- Recommendations ignore fit, stock and margin.
- A discount lifts the basket and lowers the profit.
- The attach rate looks healthy, and nobody knows what it earned.
An add-on that sells out, doesn’t fit or costs more than it earns makes the basket bigger and the month worse.

Rules and automation
Read contribution per visitor
Held-out visitors set the baseline, and any sales an add-on pulled away from other items show up.

Under 21 days, an add-on is held back
Stock decides what’s offered, so an add-on never points at a sold-out size.
How you’ll know it’s working.
Contribution per visitor
Against visitors who weren’t shown the add-on, after returns.
Attach rate
Good for diagnosis. It doesn’t say what the add-on earned.
Purchase completion
An add-on that slows the cart can cost more than it adds.

- We configure first
- Shopify’s bundles and your platform’s built-in recommendations cover fixed pairings. We check what they miss: fit, stock and margin.
- We build when
- Offers should depend on margin and stock that your platform’s recommender doesn’t see.

Questions teams ask.
Can’t our platform’s recommender do this?
It can suggest items. It usually doesn’t know your margin floor or your days of stock. We start with what you have and add the rules it lacks.
Do bundle discounts pay?
Sometimes. A discount can raise the basket and lower contribution. That’s why every offer runs against a holdout and reads in profit, not basket size.
Who owns it once it’s running?
You do. It’s built in your accounts, documented, with training for the people who run it. Ownership usually sits with your head of ecommerce, with merchandising. We can keep running it with you, or step back.
How do we start?
Usually with a conversion review: two to four weeks, a fixed fee credited to the build, and a plan that’s yours. If the job is already clear, we can scope the build directly.
