Bundles · Reviews · Discounts — live now
The umbrella over your cart.
Growing a store means collecting apps — one for bundles, one for reviews, one for discounts. Five bills. Five scripts slowing your pages. Cartrella is one suite: one account, one lightweight script, one line on your Shopify bill.

The suite
Five point apps’ jobs. One platform.
Upsell
Offers built from what your shoppers actually buy together — including which bundles they build.
Loyalty
Points and perks that already know your customers — no exports, no syncing, no fifth app to reconcile.
Prefer to start small? Each live module is also becoming a standalone app — same platform underneath, so upgrading to the suite never means migrating anything.
Different in kind
Not another 40-apps-in-one.
Bundled point apps still behave like strangers — separate data, stacked scripts, discounts fighting each other in the cart. Cartrella’s modules are built on one platform, so they actually work together:
Prices that can't drift
Packs and discounts are applied by Shopify's own checkout engine — never by fragile theme code. The price on the page is the price on the receipt, every time.
Modules that feed each other
Your review stars show up right inside the pack picker. Every module you add makes the others smarter — separate apps can't do that.
Fast by budget, not by promise
All-in-one apps are notorious for slowing storefronts. Cartrella ships one small script with a hard size budget — your Core Web Vitals stay yours.
Nothing creepy stored
No shopper emails hoarded, no tracking pixels, invitations deleted the moment they're sent. Privacy that survives an audit — because it's how the system is built.
