FIG 05 · What we build
From click to doorstep.
A store is more than a theme. It is the checkout, the back office and the box that leaves the warehouse, and we build for all of it.
01
WooCommerce and custom e-commerce
When Shopify is not the right fit, for complex catalogues, unusual pricing or an existing WordPress estate, we build on WooCommerce or a custom stack.
02
Speed and checkout
Core Web Vitals budgets, an image pipeline, an app-bloat audit and checkout UX tested on real phones.
03
AI-ready product data
Clean product data and Product schema, so AI shopping answers and Google can read, compare and recommend what you sell.
Store migrations
Migration without losing rankings
Most migration damage comes from missing redirects and lost metadata. Our checklist exists so your traffic moves with your store.
We migrate to Shopify from
- WooCommerceShopify
- Magento / Adobe CommerceShopify
- BigCommerceShopify
- WixShopify
- 01
Crawl and inventory every URL
Products, collections, pages, blog posts, images and old campaign URLs, with the traffic and links each one earns.
- 02
Map URLs and write 301 redirects
Every old URL mapped one-to-one to its new home on Shopify, loaded as 301 redirects before launch, not after.
- 03
Move products, customers and orders
Variants, images, metafields, customer accounts and order history, validated with counts and spot checks.
- 04
Carry over metadata and structured data
Titles, descriptions, alt text, canonical tags and Product, Breadcrumb and Organization schema.
- 05
Test redirects and checkout on staging
Redirect QA across the URL list, plus full test orders, tax and shipping before the switch.
- 06
Watch Search Console after launch
Crawl errors, 404s, indexing and rankings monitored closely through the first weeks, with fixes shipped fast.
Conversion
Speed, conversion and checkout
Fast pages and a calm checkout are the cheapest growth a store can buy. This is what we do on every build.
Core Web Vitals budgets
LCP, INP and CLS targets agreed up front and checked on every release, on mid-range phones, not only on a fast laptop.
An image pipeline
Responsive sizes, modern formats and lazy loading from Shopify’s CDN, so product photography stays sharp without the weight.
An app-bloat audit
Every installed app reviewed for the scripts it adds. We remove, replace or rebuild the ones that slow the store.
Checkout UX
Fewer fields, clear delivery costs, express payment options and trust details where shoppers hesitate.
AI-ready commerce
Stores that AI can read, recommend and sell
Shoppers increasingly ask an assistant what to buy. The stores it recommends are the ones with clean, structured, complete product data.
Product data and Product schema
Complete titles, attributes, prices, stock and reviews in clean structured data, so Google and AI shopping answers can read and compare what you sell.
Shopify Magic and Sidekick
Shopify’s built-in AI set up for your team, for product descriptions, admin tasks and reports, with your brand voice and review steps in place.
Agent and MCP access
Store data exposed safely through APIs and MCP servers, so AI assistants and agents can find products and help customers.
