Shopify Plus development, built at the platform's edge
Senior, founder-led Shopify Plus development for US brands scaling past standard Shopify — checkout extensibility, Shopify Functions, headless, multi-store, and deep ERP/CRM integration. No offshore hand-offs.
Plus only pays off if you use what it unlocks.
Shopify Plus starts around $2,300/mo — a real investment. Most of that value sits in capabilities standard themes and generalist agencies never touch: checkout extensibility, Functions, multi-store, and headless. We build at that edge, so Plus becomes a growth engine, not just a bigger bill.
- Paying for Plus but running it like a standard Shopify store
- Checkout you can't customize — losing conversions at the last step
- Still on Shopify Scripts (fully replaced by Functions June 30, 2026)
- A generalist agency that treats Plus like basic Shopify
- ERP, CRM, and OMS disconnected from your store, syncing by hand
- Slow Liquid storefront when you need sub-second, headless speed
- Checkout extensibility and UI extensions that lift conversion
- Shopify Functions for discounts, shipping, and payment logic
- A clean migration from Scripts to Functions before the deadline
- Senior Plus specialists — the founder is on your build
- ERP/CRM/OMS integrations that sync automatically and reliably
- Headless (Hydrogen/Oxygen) builds where speed drives revenue
The full Shopify Plus toolkit.
Everything Plus unlocks — implemented by senior developers who work at the platform's edge every day.
Checkout Extensibility
Custom checkout UI extensions, branding, and logic — the upgrade-safe replacement for checkout.liquid.
Shopify Functions
Custom discounts, shipping, and payment rules in code — replacing Scripts before the June 2026 deadline.
Headless / Hydrogen
Sub-second storefronts on Hydrogen + Oxygen where performance directly drives revenue.
Multi-Store & Expansion
Expansion stores, multi-region, and Shopify Markets for international and multi-brand operations.
ERP / CRM Integration
Reliable, automated sync with NetSuite, SAP, Salesforce, and your OMS — not manual exports.
Migration to Plus
Clean replatform from Magento, Woo, or BigCommerce onto Plus — SEO, data, and redirects preserved.
Plus development, section by section.
The checkout is where Plus earns its keep.
On Plus, checkout is finally customizable — and it's where conversion is won or lost. We build checkout UI extensions, custom fields, and validation with Functions, all upgrade-safe, so you stop leaking sales at the final step.
- Checkout UI extensions
- Custom fields & validation
- Functions-based logic
- One-page checkout tuning
Functions and Flow do the work your team shouldn't.
Shopify Functions replace Scripts (gone after June 30, 2026) and run custom discount, shipping, and payment logic natively. Paired with Flow, we automate the repetitive operations that scale poorly by hand.
- Discount & shipping Functions
- Payment customization
- Flow automation
- Scripts → Functions migration
Headless, multi-store, and integration for real volume.
When you're processing serious volume, a Liquid theme and manual back-office stop keeping up. We build headless storefronts, expansion stores, and ERP-connected operations so the platform scales with you — through BFCM and beyond.
- Hydrogen / Oxygen headless
- Expansion & multi-region stores
- ERP / CRM / OMS sync
- BFCM load readiness

Frequently asked.
A Plus specialist builds the capabilities standard Shopify and generalist agencies can't: checkout extensibility and UI extensions, Shopify Functions for custom discount/shipping/payment logic, headless (Hydrogen) storefronts, multi-store and expansion setups, and deep ERP/CRM integration. The goal is to use everything the Plus plan unlocks so the investment pays off.
It depends on your needs. Standard Shopify now covers a lot, including foundational B2B. You typically need Plus for checkout customization, Shopify Functions, unlimited B2B catalogs, expansion stores, and higher API limits. We'll tell you honestly on the first call whether Plus is worth it for your store — we won't upsell you into it.
Checkout extensibility is the modern, upgrade-safe way to customize the Plus checkout using UI extensions and Functions, replacing the old checkout.liquid. It matters because the checkout is where conversion is won or lost, and it's the highest-ROI place to customize on Plus.
Yes. Shopify Functions fully replace Shopify Scripts as of June 30, 2026. If your store still relies on Scripts for discounts or shipping logic, that needs migrating to Functions — something we handle as part of a Plus engagement.
Yes. ERP/CRM/OMS integration is core Plus work — we build reliable, automated syncs with systems like NetSuite, SAP, and Salesforce so companies, pricing, inventory, and orders stay in sync without manual exports.
Yes. We deliver senior Shopify Plus development behind your agency's brand — checkout, Functions, headless, and integrations — as a fractional extension of your team.
