Shopify development services
Custom Shopify development, theme work and backend fixes for stores that need more than the default setup.
Shopify developer London
Shopify developer London for premium D2C brands.
Treff Labs Studio builds refined Shopify stores for premium D2C brands. Custom Shopify development, ecommerce SEO, speed optimisation and migration, led by one senior operator from first audit to launch.
The gap
A good store needs one hand on the whole system.
A quick theme can get you online.
Later, the first serious round of brand, SEO or conversion work shows where the shortcuts were taken.
A beautiful design can still lose detail.
When design and build separate too early, small decisions drift and technical SEO arrives after the structure is already set.
More traffic does not make a weak store whole.
SEO and ads help when the site is ready. They do less when pages are slow, collections are unclear, or product paths are hard to follow.
What Treff Labs Studio does
The store, considered as one piece.
Treff Labs Studio brings design, custom Shopify development, ecommerce SEO, speed and migration into one coherent piece of work. It suits brands that need a Shopify SEO consultant and a developer thinking together.
Ecommerce SEO
Technical SEO, collection structure, product pages and internal links planned before launch, not added after. Often starts with a Shopify SEO audit.
Shopify speed optimisation
Lighter themes, cleaner apps and fewer scripts, so the store feels faster, calmer and easier to trust.
Shopify migration
Careful moves into Shopify, including WooCommerce to Shopify migration, redirects and launch checks.
How the work runs
One senior operator, all the way through.
The person who reviews the store also shapes the priorities, the build and the launch checks.
Find what is holding the store back.
A clear review of the build, SEO structure, speed, conversion paths and app stack. See the three audit tiers.
Turn the findings into a plan.
A ranked scope that separates quick fixes, deeper build work, content needs and launch risks.
Build the store properly.
Design-sensitive Shopify work with search, speed and commercial judgement built in from the start.
Refine after real use.
Checks after launch for indexing, speed, tracking, landing pages and the small details customers feel.
Best fit
For brands that care about the whole store.
Treff Labs Studio is for premium and luxury-adjacent D2C brands in fashion, accessories, interiors, gifting, beauty, wellness and lifestyle.
Best when the store has outgrown a basic theme, but the brand does not need a large Shopify agency around it.
Useful when presentation matters, organic visibility is weak, or the store needs better structure before more traffic is sent to it.
Not for marketplaces, dropshippers or enterprise Shopify Plus teams with in-house development resource.
Not a full-service agency with account managers, handoffs and an endless retainer stack.
Founder-led
Built from running stores, not just servicing them.
Treff Labs Studio is a London-based studio with deep experience across luxury D2C, Shopify development and ecommerce strategy. The work is shaped by years spent running a product brand, so decisions stay close to product, margin, traffic, trust and conversion.

FAQ
Common questions.
A few practical details for founders, ecommerce leads and marketing directors.
Do you work outside London?
Yes. Treff Labs Studio is London-based and works with premium D2C brands across the UK.
Do you handle migrations from Squarespace or WooCommerce?
Yes. Migration work can include WooCommerce to Shopify migration, structure, templates, product data, redirects and launch checks.
Are you a Shopify development agency?
Treff Labs Studio is intentionally smaller than a typical Shopify development agency. One senior operator stays close to the work from audit through launch.
How is this different from hiring a Shopify SEO agency?
Treff Labs Studio keeps ecommerce SEO close to the build. You get the attention of a Shopify SEO consultant while structure, collections, product pages and launch decisions are considered together. Most engagements start with a Shopify audit.
What kind of brand is the best fit?
A premium D2C brand that has outgrown a basic setup, cares how the store feels, and wants senior judgement without a large-agency layer.
Do you do Shopify Plus?
Yes, when the scope suits an operator-led studio. Large enterprise Plus teams with internal dev resource are usually not the best fit.
Do you offer retainers?
Usually, project-priced work comes first. Ongoing support can follow once there is a clear roadmap and defined scope.
How long does a typical build take?
Smaller theme and optimisation work can take weeks. Fuller rebuilds need a measured window after audit and scope.
