Arthur Blazey - Zatu Programme Manager
Migrate a high-volume UK ecommerce site off a legacy WooCommerce stack onto Shopify, without losing trade, rankings, or customer trust. Restyle the key journey pages (home, collections, product, cart), roll out full global brand styling, and build new category landing templates from scratch.
A much stronger commercial foundation, better monetisation, product discovery and a platform primed for the next growth phase.
In the months since migration:
Put simply: customers returned more and spent more, these are the compounding metrics that genuinely validate the decision to migrate.

Zatu needed depth without friction. We delivered a feature richer storefront that was easier to explore, and the results proved the approach.
Mike Fryers - Inspira Project Lead
Zatu’s migration wasn’t just about moving from WooCommerce to Shopify Plus. The real design challenge was creating a store that customers would enjoy browsing, exploring and buying from, without stripping away the detail board game fans love.
Some key improvements were:
Since launch, return customer rates have doubled, giving us a clear signal that customers are responding positively to the new storefront and that the improved buying experience is supporting repeat purchase behaviour.
One of the more complex challenges was handling mixed baskets where customers were buying products with different delivery timelines, for example, next day delivery items alongside preorders. Due to limitation of their WMS setup we couldn't rely on Shopify's native split shipping functionality.
So rather than forcing customers into separate purchases, we created a split shipping solution that allowed eligible items to be separated after checkout. This meant customers could place one order, choose split shipping, and receive available products sooner while preorder items followed separately.
Behind the scenes, the app splits eligible next day delivery items from the original order and creates a matching fulfilment order, allowing Storefeeder to process each shipment correctly.
Some key improvements were:
Migrations of this scale rarely happen as smoothly as many slick case studies will have you believe. There are always real challanges, hidden complexities and commercial realities that often get edited out of the success story.
But for us, this where the real lessons are, here's where we hit friction, uncertainty and importanly how we handled and navigated it.
Things got noisier than we anticipated...
How we responded
Timeline adjustments where handled with regular client updates, involving all partners with clear goals for shared success. This made the management of expectations and delivery clear for the client, rather than adding uncertaintly and stress.
As a direct result we adjusted our process to move the data review (both internally and with partners) to much earlier in the process.
The initial data, could have easily created tension between us and the client however rather than become defensive, we dug into the details and built out a controlled analysis with our specialist SEO Partner, Marco Felicio at Leftfield.
When we stripped seasonality, excluded clear outlier days (and importantly) uncovered the fact there was widespread GA tag double-counting in the old site. It was clear the baseline data was much better than first thought.
Daily median sessions (not peak days) were used to compare equivalent out-of-season windows pre and post-migration. This brought together a baseline data set that filtered out much of the noise and short term variability inhernt in the data set and helped provide the client with confidence things were on the right track.
The vindication
For Inspira, rooting the analysis in reality with controls, baselines, and methodology you can defend, is what separates a migration that drifts from one that compounds.
Mike Fryers - Inspira Project Lead
While the headline charts told a muted "recovery in progress" story. The controlled analysis showed there was an significant uplift of ~77% in daily organic sessions vs the pre-migration baseline - a huge win.
Migration this kind of comlexity and achieving stability is the genuinely hardest part. But the bigger prize is what comes after. And this is where our 60–90 day optimisation phase concentrates on three levers:
At current traffic volumes: this has the potential to be a +25–35% uplift in revenue efficiency, without spending a pound more on acquisition. At ~1M sessions, that's a material six-figure revenue opportunity inside a short horizon.
Migrations often get delayed, with concerns ranging from commercial impact through to concerns about resources. But they don't have to be full of uncertainty, risk and burden.
Zatu proves that with an experienced team, engaged partners, detailed planning and good execution (both pre and post live), you can really move the numbers without affecting the day to day operations.
Zatu's investment in moving to Shopify is already paying dividends. Not to mention they are now ready to engage and leverge the platform and consumer discovery as it develops in the AI age.
Cleary the runway from here is now measurable, accessible and driving business momentumn.

Following migration from WooCommerce to Shopify, Zatu delivered a +77% uplift in daily organic sessions, a +19% increase in average order value, and a near-doubling of returning customer rate (from sub-10% to ~18%). Trading volume was preserved through cutover and customer usability was materially transformed.
The Zatu Shopify migration went live in February 2026 after a 6 month build phase. Stabilisation took approximately 8 weeks post-launch, during which headline metrics showed turbulence. Underlying performance, revealed through controlled analysis stripped of seasonality and tracking anomalies, was strongly positive throughout.
Inspira Digital led the migration end-to-end, including theme build, restyle of key journey pages, and creation of new category landing templates. Orchestrating with Loncom Consulting who delivered the migration of 200k+ historical orders and Marco Felicio at Leftfield who led the SEO migration workstream and the controlled post-launch analysis that quantified the +77% organic traffic uplift.
Three primary challenges: SEO re-indexing volatility was higher than initial models suggested, post-launch conversion drifted below historical peaks after an initial bump, and the migration of 200k+ historical orders hit friction due some hidden complexity. Each was addressed through tighter feedback loops, controlled measurement, and a focused post-launch optimisation programme.
A controlled methodology was used to isolate migration impact from seasonality and tracking noise. Seasonal periods (including gifting-season uplift) were excluded, periods of known GA tag double-counting were stripped out, and clear traffic anomaly days were removed. Equivalent out-of-season windows pre- and post-migration were then compared using daily median sessions rather than peak days, producing a defensible baseline that revealed a +77% organic uplift.
AOV increased 19%, primarily because the new Shopify storefront made products materially easier to discover, browse and bundle at checkout. Improved usability translated into customers building larger baskets per visit.
The first weeks of post-launch data routinely mislead, behaviour resets, tracking that took time to stabilise, and seasonality that needed to be factored in. A controlled, baseline-anchored measurement revealed the underlying truth, which helped Zatu manage and understand progress as the site went live and bedded in.
Migration alone is not where the commercial value lives, but it is the key to unlocking your businesses full potential. The Zatu data shows the real return comes from the compounding optimisation phase that follows go-live, modelled at a +25–35% revenue efficiency uplift over the 60–90 days post-stabilisation. Even a well planned migration needs a committed post-launch optimisation to really leverage it's potential.
