Shopify Plus is not just Shopify with a higher price tag — it's a fundamentally different platform for high-volume brands.
Shopify Plus unlocks capabilities that standard Shopify doesn't provide: custom checkout via Checkout Extensibility, B2B with Markets Pro, Shopify Functions for programmatic logic, Launchpad for automated flash sale management, and unlimited staff accounts. For brands processing thousands of orders per day, these aren't nice-to-haves — they're the difference between a store that scales and one that breaks under load.
Most Shopify Plus implementations underutilise the platform. We see brands paying for Plus but using none of the exclusive features — no custom checkout, no Shopify Functions, no B2B configuration. The result is a $2,300/month platform subscription that delivers $29/month value. We implement the full Plus feature set and build the custom infrastructure that makes the upgrade genuinely worth it.

Checkout Extensibility alone can increase conversion rate by 2-4% for high-volume brands. That's worth more than the Plus subscription cost in week one.
Custom checkout is the most under-used Shopify Plus feature and the highest-impact. Standard Shopify checkout is identical for every store. Plus checkout can include order upsells, loyalty point redemption, custom delivery instructions, gift messaging, custom field collection, and custom payment logic — all built with Checkout Extensibility and Shopify UI Extensions.
We've implemented Checkout Extensibility for brands processing 5,000+ orders per day and measured direct AOV improvements of 12-18% from checkout upsells alone. Add loyalty point integration, reduced checkout abandonment from custom trust signals, and B2B net-terms billing — and the Plus subscription cost is recovered in the first month of operation.
Every service under one roof.

Answers, before you ask.
The most common questions we hear about services, process, timelines, and fit — answered plainly.
The standard upgrade triggers are $1M+ annual revenue or 10+ staff needing store access. The real trigger is when Plus features — Checkout Extensibility, B2B, Shopify Functions, or Launchpad — would materially impact your revenue. We'll model the ROI for your specific situation during our consultation.

The Complete Guide to Shopify Plus Checkout Extensibility in 2026
The Complete Guide to Shopify Plus Checkout Extensibility in 2026
Checkout Extensibility is the most powerful — and most underused — feature of Shopify Plus. Custom upsell blocks, loyalty redemption, gift messaging, and custom validation logic are all available natively in checkout now. We cover every extension point, implementation approach, and conversion impact we've measured.
B2B Commerce
Shopify Plus B2B vs. a Separate B2B Platform: The True Cost Comparison
Shopify Plus B2B vs. a Separate B2B Platform: The True Cost Comparison
Many B2C brands running B2B operations maintain a separate B2B system — a Magento installation, an ERP storefront, or a custom-built portal. Shopify Plus B2B with Markets Pro has matured to the point where consolidation is possible for most mid-market B2B operators. Here is the honest feature comparison.
Shopify Functions
What Shopify Functions Can Do That No App Can
What Shopify Functions Can Do That No App Can
Shopify Functions run in Shopify's infrastructure — not a third-party server — which means they're faster, more reliable, and more capable than anything achievable with a standard app. We cover the four function types (discounts, shipping, payment, order routing) and walk through implementation examples for each.
