Shopify Plus, built for the part the marketing reel skips.
Enterprise Shopify Plus development for brands using the platform's serious surfaces — multi-storefront, B2B, Functions, Scripts, Markets, checkout extensions. We build for the operational reality that lives behind the storefront.

What is Shopify Plus development?
Shopify Plus development is engineering work specific to Shopify Plus — checkout extensibility (Shopify Functions, checkout UI extensions), B2B catalogs, multi-store, custom apps, and Hydrogen or Next.js headless storefronts. Plus is a different ceiling than Standard Shopify and rewards engineering teams who know its specifics.
Why this exists
Shopify Plus is the surface that delivers the upgrade.
Plus pricing is justified by what it unlocks: multi-storefront, native B2B, Shopify Functions, Scripts, checkout extensibility, Markets, and dedicated launch managers. Most Plus stores still use a fraction of these. Building Plus deliberately — using the surfaces that earn the price — is what makes the platform pay back.
What we hear most
When Shopify Plus is the right answer.
Multi-storefront on the roadmap
Region-specific stores, brand portfolios, B2B vs DTC. Plus's multi-storefront is the cleanest path. Worth using deliberately.
B2B logic at scale
Customer-specific catalogs, tiered pricing, PO workflows, approval chains. Plus B2B is mature and worth picking over patched apps.
Custom checkout logic
Conditional gifts, complex discounts, market-specific payment methods, address validation. Functions and Checkout Extensions deliver.
Compliance and audit needs
Plus offers SOC 2, ISO 27001 alignment, dedicated infrastructure, and contractual SLAs that procurement actually accepts.
Multi-region selling
Markets configuration with proper pricing, currency, language, and tax handling. Plus is the platform that does this credibly.

Process
How this service runs end to end
The same six-step shape we use across every Haxtiv project — adapted to the specifics of this scope.
01
Discover
Audit, intent, and the part nobody is saying out loud
We open with a working session — not a deck. We pull analytics, crawl the existing site, audit the brand, and interview the people closest to revenue. We surface the friction inside the team, not just the friction on the screen.
02
Define
Sitemap, story, and the metrics that actually matter
We define the audience journeys, the commercial pages we are willing to defend, the SEO architecture, and the measurable outcomes. You get a shape of the project that survives feedback because it was built on evidence.
03
Design
Editorial system, art-directed, never templated
Type, grid, motion, and tone built as a system. We design the hero, the long pages, the unloved corners, and the empty states. Every screen looks like it belongs to the same studio. Nothing is parked for later.
04
Build
Production code your team can keep
WordPress, Shopify, or page builder — we build clean, accessible, performant, and documented. Component-led, naming you'll recognize next year, and a changelog your in-house team can read.
05
Launch
Migration without losing rankings or sleep
Pre-launch crawl, redirect map, schema and metadata cutover, performance baseline, and a launch playbook. We run the deploy with you, not at you.
06
Grow
Care plan, CRO sprints, and quiet improvements
We stay involved. Monthly performance reports, security and core updates, and CRO sprints that compound. The site gets better the longer you keep us.

Numbers we earn, not numbers we round up.

In their words
Senior teams who chose us.
Haxtiv replatformed our marketing site without losing a single ranking. We saw organic leads up 38% inside the first quarter and the editorial team finally has a layout system they don't fight.

Headless WordPress redesign
Our previous Shopify build was a Frankenstein of apps. The Haxtiv team simplified the stack, rebuilt the PDP and CRO patterns, and our store is faster and more profitable than it has ever been.
