Why next.js
Logged-in apps, custom checkouts and B2B portals need real logic. We build them in Next.js on Shopify’s APIs, with the storefront still on Shopify.
Dealers need to see their own price list and reorder from history.
Scoped: company accounts via Shopify B2B, a Next.js portal on Vercel reading price lists through the Admin API, and a reorder flow that drafts the order in Shopify. ~6 weeks.
Theme, hydrogen or next.js?
If the job is a storefront, a theme or Hydrogen gets there faster. Next.js is for the parts a theme can’t do: accounts, dashboards, configurators and tools.

Most clients run both: a Shopify theme for the store and one Next.js app for the thing the theme can’t do.
Inside a next.js build
Four builds, each starting from wireframes. Pick a client, then drag.

How we work
One repo, yours
Next.js on Vercel in your GitHub, with preview deploys on every PR.
Shopify stays the source of truth
Products, orders and customers live in Shopify; the app reads and writes through the APIs.
Auth that fits
Clerk for apps, Shopify B2B for dealers, so nobody manages two logins.
Observable from day one
Sentry, logs and a status page before launch, not after the first incident.
From our case studies
Real numbers from apps we built, not estimates.

Still got questions?
When the site needs real application logic, such as logged-in portals, B2B ordering or custom flows a theme can't support. For most storefronts, a well-built theme is enough.
Yes. The Next.js front end hands the cart to Shopify's hosted checkout, so payments, Shop Pay and checkout settings keep working.
Yes. We build B2B portals in Next.js on Shopify's APIs, with company accounts, price lists and reorder flows. See B2B & wholesale.
Usually on Vercel, in an account you own. Other hosts work too, and we choose with you.
Yes. The code lives in your repository with documentation, built in standard Next.js your engineers can pick up.
It depends on the app's scope. We give one fixed price after scoping. See pricing.
