Since 2012

Fun Cases ship thousands of phone cases a week across a catalogue of over 20,000 designs, and we've run their eCommerce since 2012. The latest chapter is the biggest: a complete rebrand and a ground-up new theme, with a custom product personaliser that took a five-figure app bill off the books. Revenue is up 300% over the last five years.
Chapter 01
Rebrand & Website
A full rebrand (logo, tone of voice, socials, email) carried into a ground-up Shopify theme, with a custom personaliser replacing a £5,000-a-year app.
The rebrand
A new identity, everywhere at once
Fun Cases had outgrown its old look. We rebuilt the brand from the logo up: a bold pop-art identity, a new tone of voice, and a design system of rounded blocks, ink outlines, and a palette that actually feels fun. Sacred things stayed sacred, like the promise that every order plants a tree.
Then we carried it everywhere at once. Website, social templates, and a new email marketing system in Klaviyo, all launched together so no channel lagged behind the new look.

The theme
A ground-up build for a 20,000-product catalogue
The new theme was built from scratch around how people actually buy phone cases. A mega menu with trending collections and products built in, predictive search, a native wishlist, and a slide-out cart with free-shipping and free-gift progress built in.
Every section is editor-friendly, the whole palette is a theme setting, and the in-house team can restyle or rearrange without a developer in the loop.

Phone model selector
Pick your phone once, the site follows
Nobody browsing 20,000 designs wants to check compatibility on every one. So the site asks once. Choose your phone model and it follows you everywhere: every product image across every collection, search result, and product page shows the case on your exact phone.
It removes the single biggest point of friction in buying a phone case: wondering whether the one you love fits the phone you own.
The personaliser
Design your own, without the app fee
Custom cases are a huge slice of the business, and the previous designer tool was a third-party app costing nearly £5,000 a year. We replaced it with our own: a full-screen editor built into the theme where customers add photos, text, and stickers to a live mockup of their exact phone and case type.
It exports a print-ready file straight into the order, so the studio prints from what the customer approved. No app, no monthly fee, no third-party checkout scripts. The tool now belongs to Fun Cases outright.

Chapter 02
Marketing & SEO
A growth loop that earns out each quarter across paid, lifecycle, and organic. Built on a technical SEO foundation that reads cleanly to Google and LLMs.
SEO
Ranked #1 for 'Phone Cases'
SEO was built into the rebuild, not bolted on after. Content architecture, internal linking, technical foundations, and a content program tied to the merch calendar.
Fun Cases have since peaked at #1 on Google UK for 'Phone Cases', one of the most competitive category terms in the space.

Email marketing
Thirty percent of revenue, earned quietly
Email is the highest-leverage channel in Fun Cases' stack. Lifecycle flows on Klaviyo, campaign design tied to the merch drop calendar, segmentation on real behaviour rather than vanity fields.
Over 30% of total revenue now comes through email. The kind of compounding margin that doesn't need more ad spend to stand up.

PPC
£35k a month, returning 8× and climbing
Paid media on Google and Meta. Combined spend around £35,000 a month, blended ROAS consistently above 8. Search, Shopping, Performance Max, paid social all tuned against actual product margins rather than top-line revenue alone.
No spikes. No hero launches. Compounding spend against a catalogue that keeps widening, shepherded week-to-week.
Chapter 03
Custom Apps
Three production AI tools, a custom Stock System, and an order-routing app feeding the print floor. Each one built into the Fun Cases workflow, earning its keep daily.
Order routing
From checkout to printed in two minutes
Fun Cases invested in state-of-the-art automatic printing machines, but not every order can go to them. Which route an order takes depends on the phone model and case type the customer chose.
So we built a custom routing app that makes the call on every order as it lands. Machine-compatible orders go straight to the automatic printers, no human in the loop; the rest are queued for in-house manual printing. On the automatic route, an order can be placed and printed within two minutes.

Hi Lola, sorry about that. I’ve generated a pre-paid return label for the iPhone 13 case (check your inbox) and dispatched the iPhone 14 replacement on priority shipping. It should arrive Thursday. Anything else I can sort before your trip?

Stock System
A WMS that actually fits the business
Off-the-shelf warehouse management was either too big or too limited. We built a custom WMS tailored to the Fun Cases operation. Integrated directly with Shopify, live stock, no middleware headaches, owned outright by the client.
The platform also runs a productivity tracker across the pick-and-pack team, AI-driven restock and fulfilment recommendations, and a growing set of small tools the ops team ask for and we ship. It's less of a product and more of a living system.
