Platform choice shapes your speed-to-market today and your ceiling two years from now.
The short answer
Choose Shopify when speed to revenue matters most: launch in weeks, apps cover 90% of needs, checkout is battle-tested. Choose custom when unique UX, complex catalogs or margin-killing transaction fees justify building your own rails - expect 3-4x timeline. Most D2C brands should start on Shopify and only custom-build after product-market fit makes platform limitations expensive.

Our verdict
Default to Shopify until its limits cost real money - for most brands that day is years away or never. Custom earns its premium when experience itself is the moat. We build both; the honest recommendation depends on your margins and roadmap, not ours.
Headless pairs Shopify's backend with a custom frontend (usually Next.js). You gain page-speed and design freedom while keeping Shopify operations. Worth it once traffic justifies the build; premature otherwise.
Massively - Afterfyve's German market rebuild turned speed from liability to selling point and lifted mobile conversion measurably. Every 100ms matters at checkout; slow sites tax every campaign you run.
