Your details stay with us. We never share or sell them.
01 / WHERE REVENUE LEAKS
Eight problems account for most of the money left on the table in a Shopify build. Each one has a fix we run as standard.
Page builders and locked sections force compromises. We hand-build sections your merchandisers can actually edit.
Every app adds scripts, rent and another thing to break. We replace what we can with native code and Shopify Functions.
Third-party tags and unoptimised media push LCP past four seconds. We set a performance budget per template and hold it.
Extra steps and missing wallets cost you completed orders. We tune checkout with extensions, Shop Pay and one-page flows.
Drop days and catalogue growth expose theme limits. We build for the peak, not the average Tuesday.
If changing a banner needs a developer, it does not get changed. We ship metafield-driven controls your team owns.
Without clean events you cannot prove a lift. We instrument GA4 and server-side tracking before we touch the theme.
Replatforming without a redirect map loses rankings you paid years for. Every URL is mapped before launch.

03 / PROCESS
Every engagement runs the same four stages. You know what happens next, and what you owe us at each one.
Stage 1
We review your current theme, apps and analytics, then write a fixed-scope SOW with named deliverables and a date.
Stage 2
Theme work happens in a dev store on a Git-backed workflow. You get a preview link from week one, not a reveal at the end.
Stage 3
Cross-browser and device QA, redirect map, analytics verification, then a launch window agreed with you rather than dropped on you.
Stage 4
Fourteen to sixty days of included post-launch support while real traffic finds the edge cases.

One accountable owner, weekly written updates, no account-manager telephone game.
Design decisions are argued from revenue impact, and measured after launch.

Clean handover, documented, on your repos. Leaving is never held over you.

Every drop day was a stress event before. Now they're just a Tuesday. The team built us infrastructure we can actually grow on. BFCM was the smoothest ever.

09 / SHOPIFY FAQ
Honest answers, including the ones most agencies dodge.
Standard custom themes: 4–8 weeks from kickoff to launch. Shopify Plus replatforms: 10–16 weeks. Custom app builds: 6–12 weeks. Every quote includes a fixed timeline in the SOW, no surprise extensions.
If you're doing under $1M/year, Shopify will fit. If you're over $2M/year, on B2B, multi-currency / multi-market, or need checkout extensions, Plus pays for itself fast. We have a 60-second decision framework.
No. We hand-build sections from Figma using Liquid, Online Store 2.0, and Shopify Functions where appropriate. No Shogun, GemPages, PageFly, or other bloated builders. They hurt Core Web Vitals and cost $200–$500/mo forever.
