Why RPMStack for Custom Shopify Themes

Three principles we don't compromise on.

01

Editorial-first design

We build stores that look like magazine spreads, not stock templates. Every grid, every hover, every scroll — considered.

02

Green Core Web Vitals

LCP under 2.5s, CLS under 0.1, INP under 200ms. Measured on real product pages, not the homepage.

03

Merchant-friendly editor

Every section is editable in the theme customiser. Your team ships content updates without touching Liquid.

FAQ

Common questions.

How long does a Shopify theme take?

+

A focused, well-scoped bespoke theme ships in 4–6 weeks. Larger builds with metaobjects, subscriptions, or B2B flows run 6–10 weeks.

Do you work with Shopify Plus?

+

Yes. Plus features — checkout extensions, Shopify Functions, B2B — are part of our standard toolset.

Can you improve my existing theme instead of rebuilding?

+

Often, yes. We audit the theme, benchmark performance, and give you an honest recommendation: refactor vs. rebuild. Sometimes refactor is 30% of the cost and gets you 80% of the win.
