The Services I Render

Everything I handle for Shopify merchants, from design and build to marketing and growth.

Store Design

Clean, brand-led Shopify storefronts designed around how your customers actually shop — clear navigation, strong product pages and a smooth path to checkout.

Graphic Design

Banners, product graphics, ad creatives and brand assets that keep every page and campaign looking consistent and premium.

Custom Theme Building

Bespoke Liquid themes and custom sections built on Online Store 2.0, so your team can edit layouts and content without touching code.

Email Marketing & Automation

Welcome, abandoned cart, win-back and post-purchase flows set up in Klaviyo or Shopify Email to turn one-time buyers into repeat customers.

Shopify Marketing

Promotions, discounts, bundles, upsells and campaign pages planned and built to lift average order value and sell-through.

SEO Optimization

Keyword-led product and collection content, clean site structure, fast load times and technical fixes so your store is found on Google.

Store Migration

Moving from WooCommerce, Wix, Magento or BigCommerce to Shopify with products, customers, orders and redirects fully mapped — no lost rankings.

Payment & Shipping Setup

Payment gateways, taxes, shipping zones and rates configured correctly so checkout works reliably in every market you sell to.

Social Media Marketing

Instagram, Facebook and TikTok shops connected to your catalogue, plus content and ad creatives that drive traffic back to the store.

Why Kartio

A Shopify Partner, Not Just A Coder

A partner, not a vendor

Built for revenue

Every decision maps to conversion rate, average order value or repeat purchases.

Clear, jargon-free updates

Weekly progress notes in plain language, with a preview store you can click through.

Merchant-friendly code

Editable sections and clean Liquid, so your team can run the store without a developer.
