CRO service

Shopify conversion rate optimization that starts at the checkout, not the homepage.

Most CRO agencies begin with the homepage and product pages because that is where the design work is. We begin at the checkout, because that is where a buyer who already decided to pay is lost, and because most of the leaks there are payment and form problems that no A/B test on a hero image will fix. This is a service page: what we look at, what we change, how it is measured. No case studies invented, no guarantees.

What we review first

Checkout completion by device and payment method. The number, not the story.
Decline rate and decline reasons. Issuer declines, 3DS failures, gateway timeouts, velocity blocks.
Form friction. Field count, autocomplete, phone and address rules per market, account walls.
Cost visibility. When shipping, tax and fees appear, and how often they change the total late.
Currency and language. Whether buyers see and pay in their own.
Speed. Render and interaction timing on a mid-range phone on a slow connection.
Trust. Descriptor, returns summary, contact route, wallet presence.

What we change

Payment layer

A second acquirer where declines are the leak, routing by card region, retry on soft declines. This is usually the biggest single lift and it is invisible to the buyer.

Checkout page

Single-page layout, field rules per country, totals up front, currency per buyer, order bumps and one-click upsells where the offer fits.

Storefront handoff

Cart drawer, buy-button behaviour, pixel and server-side events so attribution survives the move to a checkout subdomain.

Where the leak is upstream of the checkout, product page or offer, we say so and either scope it separately or point you to someone better placed. Design and build services.

How it is measured

One metric owns the engagement: checkout completion rate, measured as paid orders divided by checkout sessions, split by device and payment method, compared over equal periods with the same traffic sources. Average order value is reported beside it so an upsell that hurts completion is caught. Decline recovery is reported as its own line: attempts declined on the first route and captured on the second. All of it is on the store dashboard, not in a slide deck.

Who it suits

Stores with real checkout traffic, roughly a few hundred checkout sessions a month or more, so changes can be measured.
Stores in restricted or cross-border categories where declines are a large share of the loss.
Stores on Shopify's native checkout that have hit its customisation limits.
Stores that already run a CascadeCheckout checkout and want the numbers tuned.

Not a fit: stores under a hundred orders a month, where traffic quality is the problem and a checkout change cannot be measured.

How the engagement runs

You send the store URL and a month of checkout numbers from Shopify analytics or your gateway.
We return a written read within a few days: where completion is lost, in order of likely impact.
You pick what to change. Payment-layer work ships on the CascadeCheckout platform; page and storefront work ships as design and build.
Changes go live one at a time so each one can be measured.

Frequent questions

What does a Shopify CRO service actually do?

Reviews where buyers are lost, changes the checkout, payment layer and storefront handoff, and measures completion rate before and after. Ours starts at the checkout because that is where decided buyers leak.

Do you guarantee a conversion increase?

No. We report the numbers honestly. The changes with the most reliable effect are decline recovery, cost visibility and form reduction; how much they move your store depends on where it leaks.

Do I need to move off Shopify?

No. The storefront stays on Shopify. Payment-layer changes run on a checkout subdomain that writes orders back into Shopify.

How is this different from a CRO agency?

Agencies typically test page designs. We fix payment declines, currency and form rules first, because they are measurable and usually larger, then look at design.

Send your store URL and last month's checkout numbers.

You get a written read of where completion is lost before anything is built.

CascadeCheckout is checkout software, not a payment service provider, bank or merchant-account seller. You contract with your own gateway or acquirer, disclose your real business category to them, and receive payouts from them. We never hold funds and we do not promise that any processor will approve you.
