01 / WHERE REVENUE LEAKS

Where Shopify stores leak revenue, and what we do about it.

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.

Restrictive themes

Page builders and locked sections force compromises. We hand-build sections your merchandisers can actually edit.

App bloat and conflicts

Every app adds scripts, rent and another thing to break. We replace what we can with native code and Shopify Functions.

Slow load times

Third-party tags and unoptimised media push LCP past four seconds. We set a performance budget per template and hold it.

Clunky checkout

Extra steps and missing wallets cost you completed orders. We tune checkout with extensions, Shop Pay and one-page flows.

Scaling bottlenecks

Drop days and catalogue growth expose theme limits. We build for the peak, not the average Tuesday.

Painful admin UX

If changing a banner needs a developer, it does not get changed. We ship metafield-driven controls your team owns.

No analytics baseline

Without clean events you cannot prove a lift. We instrument GA4 and server-side tracking before we touch the theme.

SEO regressions

Replatforming without a redirect map loses rankings you paid years for. Every URL is mapped before launch.

02 / CAPABILITIES

03 / PROCESS

How a Shopify build runs.

Every engagement runs the same four stages. You know what happens next, and what you owe us at each one.

  1. Stage 1

    Audit and scope

    We review your current theme, apps and analytics, then write a fixed-scope SOW with named deliverables and a date.

  2. Stage 2

    Design and build

    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.

  3. Stage 3

    QA and launch

    Cross-browser and device QA, redirect map, analytics verification, then a launch window agreed with you rather than dropped on you.

  4. Stage 4

    Hypercare

    Fourteen to sixty days of included post-launch support while real traffic finds the edge cases.

Conversion-first, not pixel-first

Design decisions are argued from revenue impact, and measured after launch.

Transparent, fixed-scope pricing

Written scope and a fixed number before work starts. No surprise line items.

You own the code, always

09 / SHOPIFY FAQ

Questions we hear before every Shopify engagement.

Honest answers, including the ones most agencies dodge.

How long does a custom Shopify build take?

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.

Should I be on Shopify or Shopify Plus?

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.

Do you use Dawn or a theme builder like Shogun?

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.

What does a typical engagement cost?

Custom themes: $15K–$45K. Shopify Plus replatforms: $50K–$250K. Apps: $10K–$80K. Monthly retainers: $1.2K–$12K/mo. Every quote is fixed-fee, locked in the SOW, no hidden change orders.

Will you migrate us without losing SEO?

Yes. We've migrated 8,000+ SKUs from Magento, WooCommerce, BigCommerce, and Salesforce with zero downtime and a redirect map that preserves 90%+ of organic traffic. URL parity, schema parity, and a 30-day post-launch SEO monitor.

Can you handle our scale?

We've shipped for brands from $100K to $50M+ in annual revenue. Largest active Shopify Plus retainer: 150 hrs/month with a signed SLA. Smallest: $1.2K/mo for a 10-hour tune-up.
