What we build
Shopify Development services
Pick an area to see how we can help, from new builds to long-term care.
New Shopify stores
From an empty account to a launched store: information architecture, theme, catalog import, payments, shipping and tax set up properly.
Shopify Plus setups
Expansion stores, checkout extensibility, B2B catalogs and automation with Shopify Flow for teams outgrowing standard plans.
Store redesigns
A refreshed storefront built on Online Store 2.0 sections, so merchandisers can change pages without a developer.
Private apps
Custom apps on the Admin and Storefront APIs for logic no public app covers, hosted and monitored by us.
Checkout extensions
Checkout UI extensions and Functions for discounts, delivery rules and custom fields that stay upgrade-safe.
App consolidation
Replace a stack of overlapping apps with leaner custom code to cut monthly fees and script weight.
Hydrogen storefronts
React storefronts on Hydrogen and Oxygen with streaming rendering and Shopify-native data loading.
Next.js on Shopify
Headless stores built with Next.js and the Storefront API, deployed to the edge and paired with a headless CMS.
Content-led commerce
Editorial pages, lookbooks and shoppable stories managed in your CMS and powered by Shopify checkout.
ERP and inventory
Two-way sync of products, stock, orders and invoices with Odoo, NetSuite, SAP or your own ERP.
PIM and DAM
Rich product data from Akeneo or Pimcore published to Shopify with variants, metafields and media.
Marketing and CRM
Clean customer and order events flowing to Klaviyo, HubSpot or Salesforce for segmentation and service.
01
Themes that are fast and easy to run
We build Online Store 2.0 themes from a component library, so your team can compose pages from sections while performance stays inside an agreed budget.
- Section and block-based layouts
- Core Web Vitals budgets per template
- Accessible, keyboard-friendly UI
02
Custom logic where apps fall short
When a public app does not fit, we write a focused private app or Shopify Function instead of bending your process around someone else’s product.
- Admin and Storefront API apps
- Shopify Functions for discounts and delivery
- Monitored hosting and logs
03
Selling beyond the website
Point of sale, marketplaces, social channels and wholesale can all run from one Shopify admin when catalog and stock are modelled properly.
- Shopify POS roll-outs
- B2B catalogs and price lists
- Marketplace and social feeds
04
Operations that keep up with sales
We connect Shopify with fulfilment, ERP and finance so orders, stock and payouts reconcile without manual exports at the end of every day.
- Order routing and 3PL integration
- Inventory sync across locations
- Payout and tax reconciliation

Years in commerce
A store on a customised theme usually takes 6 to 10 weeks. Custom designs, headless builds and complex integrations take longer, and we confirm a timeline after discovery.
Yes. We set up expansion stores, checkout extensibility, B2B features and Shopify Flow automations, and we help teams decide whether Plus is worth it for them.
We map every product, category and content URL to its new address, set up 301 redirects, carry over metadata and monitor search traffic after launch.
If a well-supported app covers most of the need, we recommend it. We suggest custom code when apps overlap, slow the store down or cannot match your process.
Yes. Support plans cover monitoring, fixes, theme and app updates, and a monthly backlog of improvements agreed with your team.
