🌐Senior team, direct ratesA senior team billing at real engineering rates — not $150/hr Western agency time. Same code quality, a fraction of the price.
📋Fixed scope, no wasteA price per deliverable agreed up front — no padded timesheets, no scope-creep invoices. You pay for the build, nothing else.
Team vs Freelancer
Why a senior team beats a cheap freelancer
Same budget range — very different risk. Here is what changes when a full team owns your project instead of one person juggling ten clients.
A solo freelancer
×They go quiet. The #1 complaint — overcommitted freelancers fall behind, then disappear mid-build or months after launch.
×Single point of failure. One person gets sick, busy or takes another gig — and your project just stops. No backup.
×No process. No staging, no backups before changes, no QA or code review — bugs ship straight to your live site.
×No handover. Rarely any documentation, so the next developer has to reverse-engineer everything.
×Cheap upfront, costly later. Messy code means the next dev charges double — a $3k site can cost $8k to rescue.
×Access left open. They keep admin keys to your hosting, domain and CMS long after — and after they vanish.

🔄 Our Shopify Plus Development Process
Enterprise development requires enterprise process — here is how we deliver Shopify Plus projects at scale.
🔍 1. Enterprise Discovery
We map your business requirements, existing tech stack, integration needs, and Shopify Plus feature requirements before any code is written.
📐 2. Architecture Design
System architecture is designed — app structure, API data flows, Function specifications, and multi-storefront setup documented.
🧱 3. Agile Build
2-week sprint cycles with weekly demos. You review each feature in a development store before it moves to staging.
🚀 4. UAT & Launch
Full enterprise QA, load testing, integration validation, and staged launch with post-go-live monitoring included.
Before We Start
How to prepare for your Shopify Plus project
A little prep makes the build faster and de-risks the migration. Missing some of it? The enterprise discovery call sorts it out.
✓
Current stack & data volume
Platform, catalogue size, order volume and traffic — so we architect for your real scale.
✓
B2B & wholesale rules
Customer-specific pricing, net terms, quantity rules, tax exemptions — if any apply.
✓
ERP / CRM / OMS
Which systems must stay in sync (NetSuite, SAP, Salesforce, a 3PL) and how.
✓
Multi-store & markets
Regions, currencies, languages and any expansion-store plans.
✓
Checkout needs
Custom fields, upsells, delivery logic or B2B approval flows for checkout.
✓
Access & compliance
Shopify Plus org access, domain, and any security/compliance requirements.
Not sure on some of it? Book the enterprise discovery call anyway. Mapping scale, integrations and B2B rules is exactly what discovery is for.

Quality, Not Just Speed
Common Shopify Plus problems we prevent
Enterprise builds fail quietly — an over-app’d store, a checkout no one can maintain, integrations that drift. These are the failure modes we engineer out.

❓ Frequently Asked Questions
Common questions about Shopify Plus development answered directly.
Shopify Plus is Shopify's enterprise commerce platform designed for high-volume merchants, typically those generating $1M+ in annual revenue. It offers checkout extensibility, native B2B wholesale, Shopify Functions for custom logic, unlimited staff accounts, multi-storefront management via Organization Admin, dedicated Merchant Success support, and higher API rate limits.
Shopify Plus adds: Checkout UI Extensions (add custom React UI to Shopify's checkout), Shopify Functions for fully custom discount, shipping, and cart transform logic, the B2B wholesale portal with company accounts and price lists, multi-storefront management, Launchpad for automated sale/launch scheduling, and expanded Checkout Branding API for deeper visual customization.
Shopify Plus pricing depends on scope. Smaller customizations and focused tweaks start at $50, while more involved custom work — checkout extensions, B2B features, or integrations — typically runs $200–$1,000. Larger enterprise builds are quoted fixed-price after a free scoping call.
Shopify Functions are small programs compiled to WebAssembly that run inside Shopify's infrastructure. You write the function in Rust, JavaScript, Go, or AssemblyScript, compile it to WebAssembly, and deploy it as a custom app extension. Functions execute server-side during checkout operations — discounts, shipping, cart transforms, and payment customization — with no external server required.
Shopify Plus is worth it once you outgrow standard Shopify - typically high order volume, the need for checkout customization, B2B/wholesale, multiple storefronts, or advanced automation. If you do not yet need those capabilities, standard or Advanced Shopify is more cost-effective. We can help you weigh your volume and roadmap against the Plus feature set before you commit.
No. AI speeds up Shopify development by generating Liquid snippets, debugging, and drafting code, but it does not replace the judgment needed for store architecture, custom app logic, checkout extensibility, performance, and integrations. In practice AI makes experienced Shopify developers faster - complex Plus builds still need a developer to design and ship them correctly.
Shopify Plus unlocks deep checkout control through Checkout Extensibility - custom fields, branding, upsells, validation, and discount logic via Shopify Functions and UI extensions (the modern replacement for checkout.liquid). This lets you tailor the highest-converting page of your store in ways standard Shopify does not permit.
Advanced is the top standard tier; Plus is the enterprise platform. Plus adds checkout customization, Shopify Functions, B2B/wholesale, up to multiple expansion stores, higher API limits, organization admin, and dedicated support - aimed at high-volume and complex merchants. Advanced suits growing stores that do not yet need enterprise-grade customization.
For most stores, no. Those $25,000–$75,000 quotes are mostly agency overhead — account managers, sales and markups — not engineering. You get the same Plus / headless architecture built by a senior team at real rates: a fixed price agreed up front, a working preview before you pay, code you own outright, and no retainer you are locked into afterwards. Shopify’s Plus Partner badge is a sales tier, not a guarantee of better code.

📈 SEO (Search Engine Optimization)
Technical SEO, on-page, schema, and architecture built to rank.
“Very few web teams understand Meta ads logic. This one builds layered headings and value blocks from a conversion standpoint, and separates one-time projects from optional monthly data monitoring. Reusing their landing pages across dozens of our clients has cut our communication overhead dramatically.”
— Media-Buying Lead, multi-store management studio
“Most outsourcers just drop your content into a template. They broke down our audience’s pain points first and built the page’s guarantee section around them. Clear pricing, no hidden monthly lock-ins, add-to-cart rose noticeably after the Shopify theme rework, and the ad-creative-to-landing-page match was spot-on.”
“Our self-built Shopify store had stubbornly low conversion. They designed the pain-point guarantee module specifically against competitors’ weak spots, fixed the landing-page expectation gap completely, and on the same ad budget CVR rose by nearly a third. Transparent pricing with no forced long-term retainer — a lot of freedom to work together.”
