Who is behind craftberry
What we build and run
Across more than 800 Shopify builds, we have seen the strongest results come when strategy, UX/UI, development, CRO, and support work as one team.
Custom Shopify and Shopify Plus development
We build the theme around your catalogue and operations rather than forcing a growing range into a generic template. Clean, maintainable code, merchant-editable sections, and a front end engineered for Core Web Vitals.
App and custom functionality development
We build private apps, custom API and ERP connections, and bespoke storefront tools when off-the-shelf apps fall short or conflict.
Conversion rate optimisation
Our in-house CRO team tests placement, framing, and speed against your own traffic.
B2B and wholesale
Company accounts, tiered and wholesale pricing, custom payment terms, and the ERP integrations behind them.
Internationalisation
One Shopify Plus store serving many markets: currency, duties, regional pricing, and fulfilment routing from a single backend.
Ongoing support and optimisation
A long-term development team after launch, not a handoff.
Store migration
Moving off Magento, WooCommerce, Shopware, or a legacy platform with data and SEO preserved. Covered in full on our Shopify migration page.

A stronger Shopify store starts with the right technical plan.
Speak directly with our team about your requirements, risks, integrations, and the best route forward.
We have a carefully curated tech stack we use on Shopify builds to extend funtionality and improve operations.
Tools we work with regularly
/){kind=logo}
Skio
A subscription platform built around a flexible customer experience.
We use it for brands that need self-service subscription management, including options to skip, swap, pause, or reschedule deliveries.
/){kind=logo}
Global-e
A cross-border commerce solution for brands selling internationally.
We use it to support local currencies, duties, taxes, payment methods, and international fulfilment across multiple markets.
/)
Gadget
A platform for building custom Shopify apps, integrations, and serverless backends.
As a Gadget development partner, we use it when a business needs functionality or data connections that cannot be handled reliably by an off-the-shelf app.
/)
Intelligems
An A/B testing and profit optimisation platform for Shopify.
We use it to test pricing, shipping thresholds, discounts, offers, and storefront changes against commercial outcomes rather than conversion rate alone.
How our process as a Shopify development agency works
Most custom Shopify builds take around eight weeks.
Shopify Plus projects with complex integrations, large catalogues, or custom app development typically take longer.
Discovery and technical planning (1 to 2 weeks)
We review your catalogue, existing theme or platform, required integrations, data structure, custom functionality, and internal workflows.
This helps us define the Shopify architecture and identify technical risks before development starts
UX/UI design (2 to 4 weeks)
We create the key storefront layouts in Figma, keeping this stage focused on the customer journey, reusable Shopify sections, and the functionality the development team needs to support.
Shopify development (4 to 8 weeks)
Our developers build the custom theme, Shopify sections, metafield structure, integrations, and bespoke features.
We test throughout the build and share progress in regular check-ins.
QA, launch, and ongoing development
Before launch, we test functionality, responsiveness, performance, tracking, and integrations across the store.
After go-live, we can continue with Shopify development support, CRO, performance improvements, and new features.
When a custom build is worth it
We have seen off-the-shelf themes work for early-stage stores with straightforward catalogues and limited operational complexity.
The problems usually appear later, when repeated workarounds, extra apps, and theme restrictions start increasing development cost and slowing down change.
| Custom craftberry build | Off-the-shelf / templated theme | |
|---|---|---|
| Control over UX and structure | Full: DOM, script loading, layout, metafields | Limited to the template's options |
| Performance ceiling | High: engineered for Core Web Vitals | Capped by template code and bundled apps |
| Complex catalogues and variants | Built for it, including past the 250-variant limit | Struggles as the catalogue grows |
| Integrations and ERP | Custom API and ERP connections | App-dependent, limited |
| Merchant editing | Sections built around how your team works | Generic, sometimes rigid |
| Upfront time and cost | Higher upfront, lower long-run cost | Cheaper upfront, hits a ceiling |
| Best fit | Scaling brands that have outgrown a template | Early-stage stores validating the market |
