If you run a Shopify store with GA4, Klaviyo, and the usual stack, you can see sessions, orders, and abandoned checkouts—but the stretch between add-to-cart and purchase often stays invisible. You might have 80 people add to cart and 20 complete an order; the 60 in between are just gone. Did they leave at the shipping step? Spend 20 minutes on a discount code that didn’t work? Bail at the payment field? GA shows you pages. Klaviyo shows you emails. Shopify shows you orders. Nobody shows you the checkout at a field level. Zuko Checkout Analytics is a Shopify app that tracks customer behavior inside checkout so you can see exactly where shoppers drop, which validation or error messages fire, and how much money those issues are costing you.
What Zuko Does
Zuko Checkout Analytics tracks how customers interact with your Shopify checkout at the field level. Instead of only knowing that a checkout was completed or abandoned, you see which specific fields cause hesitation, errors, or abandonment, and the monetary amount of sales lost to each. It works directly with Shopify checkout (including Checkout Extensibility) with a no-code setup, so you get actionable insight without complex configuration.
Key Features
- Field-level drop-off — See where in the checkout form customers abandon (e.g. email, shipping address, payment method) so you can fix the right place.
- Lost sales and conversion trends — Track lost sales and checkout conversion rate over time so you can measure the impact of changes.
- Error and validation tracking — Monitor which validation and error messages are triggered during checkout (e.g. invalid card, address issues) so you know what’s blocking completion.
- Cost of checkout issues — Understand how much money specific checkout issues are costing you, not just that people dropped.
- Quick install — No-code setup that works with Shopify checkout out of the box.
Who It’s For
Zuko is built for ecommerce, UX, and optimization teams who want actionable insight into checkout performance without complex setup. If you’re making pricing or promotion decisions based on incomplete information—you see add-to-cart and orders but not the path between—Zuko gives you the missing layer.
Pricing
Zuko offers a free plan (500 sessions per month) and paid tiers by session volume: Starter $29/month (5,000 sessions), Growth $49/month (10,000 sessions), and Scale $99/month (25,000 sessions, plus Checkout sessions API data export and a dedicated Success Manager). All tiers include checkout conversion analytics and error message tracking. Annual billing saves 20%.
How It Fits Your Stack
GA4 gives you funnel steps (e.g. begin_checkout, purchase) if you’ve implemented ecommerce events; Klaviyo uses “Added to Cart” and “Started Checkout” for flows; Shopify gives you orders and abandoned checkouts. None of them show you which fields in checkout cause drop-off or which errors are blocking sales. Zuko adds that checkout-field layer so you can see, for example, whether discount codes, shipping, or payment are the main leak—and how much each is costing you.
Getting Started
Install from the Shopify App Store with a no-code setup: Zuko Checkout Analytics. It connects directly to Shopify checkout, so once installed you can start seeing field-level drop-off, errors, and lost sales without extra configuration.
Wrap-Up
If checkout has felt like a black box—you see cart adds and orders but not the “60 in between”—Zuko Checkout Analytics gives you the field-level data to fix what’s actually costing you.
