Ecommerce development

Stores built for the way your customers actually buy

Product discovery that fits your catalogue, a checkout with fewer places to give up, and inventory that matches what's on the shelf. On Shopify, WooCommerce, or a headless build — whichever your numbers point to.

The short version

Ecommerce website development, end to end

Two stores can sell the same number of products and need completely different sites. Forty considered-purchase SKUs need comparison and specification depth. Four thousand SKUs need search, filtering, and merchandising rules. Building the second when you need the first wastes months.

So we start with the catalogue and the customer's decision. What do they compare? What makes them hesitate? What do they ask before they'll commit? Those answers determine the product template, the filter set, and how much of the story goes on the collection page instead of behind a click.

Then the operational half, which is where ecommerce projects quietly fail: inventory sync, tax by region, shipping rules that reflect your real carriers, returns, and transactional email. If those are wrong, a beautiful store creates support tickets instead of revenue.

What you end up with
  • Product discovery tuned to your catalogue size, not a template default
  • Checkout drop-off measured step by step, then reduced
  • Inventory, tax, and shipping accurate at launch — not a phase two
  • Product and collection pages that earn organic traffic on their own
Scope

What an ecommerce build covers

Search, filtering, and merchandising

Faceted filters from real product attributes, synonym handling in search, and sort rules you control per collection.

Product experience

Variant logic, bundles and kits, size guidance, stock accuracy, reviews, and the specification depth your category needs.

Checkout and payments

Fewest possible steps, guest checkout, wallets, address autocomplete, and local payment methods per market.

Inventory and fulfilment

ERP, 3PL, or POS sync so stock is right. Multi-location, pre-orders, and backorders handled explicitly.

Tax, shipping, and multi-region

Real rates, thresholds, duties, and currency by region. Configured against your carriers, not guessed.

Lifecycle email and analytics

Abandoned cart, post-purchase, and win-back flows, plus GA4 ecommerce events that reconcile with your order data.

How it runs

The process, stage by stage

No stage starts before the last one is signed off. You always know what's next and what we need from you.

  1. 01

    Catalogue and margin review

    SKU count, attributes, price bands, and margin by line. This decides platform and architecture more than anything else.

    • Catalogue analysis
    • Attribute mapping
    • Margin review
    • Platform recommendation
  2. 02

    Buying journey

    How customers choose, compare, and hesitate — mapped to templates and filters.

    • Journey map
    • Template list
    • Filter and facet plan
    • Objection inventory
  3. 03

    Build the storefront

    Templates and components built against a real copy of your catalogue on a staging store.

    • Product templates
    • Collection pages
    • Cart and checkout
    • Search and filters
  4. 04

    Wire the operations

    Inventory, tax, shipping, payments, and email. Then test orders through every combination that matters.

    • Tax and shipping
    • Payment gateways
    • Full test orders
  5. 05

    Launch and optimise

    Go live, watch the funnel daily for a fortnight, then act on what the data shows rather than what we assumed.

    • Launch checklist
    • Funnel monitoring
    • Ranked fix list

Tools

What we build it with

Picked per project, not per fashion cycle. Here's the usual shortlist and why each one is on it.

Shopify
Default for most catalogues under a few thousand SKUs
WooCommerce
When product logic is unusual or WordPress is fixed
Hydrogen / Next.js
Headless storefronts for large or multi-market stores
Stripe
Payments outside a hosted platform
Algolia
Search and faceting at scale
Klaviyo
Lifecycle email and SMS
We'd been told our store needed a redesign. Quesiono looked at it and said the design was fine, the problem was eleven apps and a five-step checkout. That was a cheaper answer than the one we expected and it worked — conversion is up 25% on the same traffic.

Where we've done this before

Industry context changes the brief. These are the ones whose pitfalls we already know.

Questions

The things people ask before we start

Shopify for most stores — the operational load it absorbs is worth the fee. WooCommerce when you're committed to WordPress or need product logic Shopify won't bend to. Headless when you have a large catalogue, several markets, or a content-heavy storefront. We'll make a recommendation with reasoning after looking at your catalogue and order volume.
