Built for the next.
The commerce stack is changing faster than most brands realise. AI isn't just analysing stores anymore - it's starting to operate them. Shopify has already shipped MCP servers that let AI agents read your catalogue, query inventory, and take action programmatically.

The brands that will use this well are the ones built on structured data, clean integrations, and API-first architecture.

That's how we build - not because it's trendy, but because the gap between stores built this way and stores that weren't is going to be significant.

Frequently Asked Questions

If you have more questions, we're happy to answer them - just reach out.

How does your pricing work?

Every project is scoped as a fixed-price engagement. No hourly billing, no open-ended retainers during the build. We start with a paid Discovery phase to define scope, technical requirements, and priorities - then deliver a clear proposal with a fixed cost and timeline before any design or development begins. Post-launch, most clients move to a monthly retainer for ongoing development, optimisation, and new features.

Is all your work done in-house?

Yes. Design, engineering, strategy - all done by our core group of senior specialists. The same people work across every project. We don't outsource offshore or rotate through developers you'll never meet. The people on your kickoff call are the same people building your infrastructure.

How long does a typical Shopify Plus project take?

A standard Shopify Plus build runs 8-12 weeks from kickoff to launch. Headless builds or projects with complex integrations typically land in the 12-18 week range. Every engagement starts with a Discovery phase to lock in scope, technical requirements, and priorities before design or development begins. That upfront work is what keeps timelines tight and prevents scope creep mid-project.

What size businesses do you work with?

We work with brands doing $5M to $100M+ in annual revenue - businesses that have found product-market fit and are ready to scale their commerce infrastructure. Our clients range from high-growth DTC brands upgrading to Shopify Plus, through to established retailers running complex multi-region or B2B/DTC operations.

Why Shopify Plus over other platforms?

We've built on most major ecommerce platforms over the past 14 years. Shopify Plus consistently wins for scaling brands because of its reliability, ecosystem, and total cost of ownership. You're not paying for server infrastructure, security patches, or platform maintenance. With headless architecture through, you get full frontend flexibility without the overhead of managing a custom stack from scratch.

Can you migrate us from another platform?

Yes. We've migrated brands from Magento, WooCommerce, BigCommerce, Salesforce Commerce Cloud, and custom-built platforms onto Shopify Plus. Migration is more than moving data - it's rethinking your information architecture, URL structure, integrations, and customer experience for a platform built to scale. We handle the full process: data migration, SEO preservation, custom integration mapping, and a phased launch plan.

Do you offer ongoing support after launch?

Yes. We treat post-launch as a roadmap, not a to-do list - prioritising features, optimisations, and integrations based on what's actually driving revenue. You're not locked into a long-term contract, but the brands that get the most out of their Shopify Plus investment are the ones that keep building after go-live.
