Propeller plans and builds Shopify Plus systems - checkout extensibility, Functions, B2B, multi-market, and high-volume architecture - without enterprise theater. Santa Monica studio, shipping worldwide.
What's broken
- Standard Shopify no longer fits the complexity.
- Legacy platforms cost too much to change and too long to ship.
- Checkout, B2B, and multi-market need architecture - not another app stack.
How we fix it
We implement Shopify Plus as intended: Functions, checkout extensibility, wholesale, automation, and clean integrations.
Architecture first. Theme code second.

Why Propeller
Shopify Plus is not a bigger theme. It is an operating system for volume, checkout customization, B2B, and multi-market complexity.
Propeller helps brands decide when Plus is earned - then migrate and implement Functions, checkout extensibility, wholesale, and integrations without enterprise drag.

FAQ
When should a brand move to Shopify Plus?
When checkout extensibility, B2B, multi-market, or automation volume outgrow standard Shopify - not because a peer’s footer says Plus. Propeller audits fit before recommending the upgrade.
Can you migrate us to Plus from Magento or SFCC?
Yes. Structured Shopify Plus migrations covering catalog, customers, SEO redirects, and integrations - planned from our Santa Monica studio.
Is Propeller a Shopify Plus agency in Los Angeles?
Yes. Propeller is a Los Angeles / Santa Monica Shopify Plus agency - scalable Plus systems and multi-market architecture for ambitious brands.
What is the difference between Shopify and Shopify Plus?
Plus unlocks enterprise checkout customization, higher API limits, Shopify Functions, B2B company accounts, and multi-store tooling. Standard Shopify remains the right plan for many growing brands. We recommend Plus when architecture - not vanity - requires it.
Do you handle Plus checkout extensibility and Shopify Functions?
Yes. Checkout UI extensions, Functions for discounts and validation, and post-purchase flows are core Plus workstreams - designed for conversion, not clutter.
