What does a Shopify Plus development agency do?
A Shopify Plus development agency engineers the enterprise capabilities that make Plus worth its higher platform fee: custom checkout logic, wholesale on the same platform, multiple regional storefronts, automation and deep integration with back-office systems. The work is closer to enterprise software delivery than to theme design.
As a Shopify Plus Certified Partner with 350+ ecommerce projects behind us, we take brands from evaluation through replatforming, launch and ongoing optimization. If you are a smaller merchant that does not yet need Plus, our Shopify development services are the better fit.
When is it time to move to Shopify Plus?
It is time to move to Shopify Plus when your current platform limits checkout, wholesale or international growth, or when an enterprise platform's maintenance cost outweighs its flexibility. We see three common starting points.
- Scaling Shopify merchants who need checkout customization, more staff accounts, Launchpad campaigns or higher API capacity for integrations.
- Magento and Adobe Commerce brands tired of hosting, patching and upgrade projects that consume the development budget.
- B2B and hybrid sellers who want DTC and wholesale customers served from one catalog, one inventory pool and one admin.
If you are weighing an enterprise move, our comparison of Magento vs Shopify Plus covers total cost of ownership, flexibility and team requirements.
Our Shopify Plus capabilities
Our Shopify Plus experts cover every layer of the platform, from checkout to infrastructure-free headless storefronts.
Checkout extensibility and Shopify Functions
Shopify has replaced checkout.liquid with checkout extensibility, so custom checkout behavior is now built with checkout UI extensions and Shopify Functions. We build custom pricing and promotion logic, payment and delivery customizations, and cart and checkout validation that run on Shopify's infrastructure and survive platform updates.
Expansion stores and international selling
Plus includes additional expansion stores for regions, brands or wholesale. We design shared themes, product data flows and Shopify Markets settings so currencies, languages, duties and pricing stay consistent across storefronts.
Automation with Shopify Flow and Launchpad
We automate order tagging, fraud review, inventory alerts and customer segmentation with Shopify Flow, and schedule product drops and sales with Launchpad so campaigns go live without late-night manual work.
Headless Shopify Plus
For brands that need full front-end control, we build Hydrogen or Next.js storefronts on the Storefront API. Our headless commerce development team decides with you whether headless genuinely pays off or whether a well-built Online Store 2.0 theme will perform just as well.
Enterprise integrations
Plus stores rarely operate alone. We connect Shopify Plus to ERP, PIM, OMS, 3PL and CRM systems through monitored middleware, with queueing and retry logic that respects Shopify's API rate limits and keeps inventory, pricing and order status accurate during peak traffic.
Shopify Plus B2B: wholesale and DTC on one platform
Shopify Plus B2B lets you sell to wholesale buyers from the same store and admin as your DTC customers. Company accounts with multiple locations and buyers, customer-specific catalogs and price lists, quantity rules, volume pricing, payment terms and draft-order quoting are available natively.
We configure these features, connect them to your ERP for account, pricing and inventory sync, and build custom Functions or apps where your trade terms go beyond the standard toolset. The result is one platform to operate instead of a separate wholesale portal.
Wholesale buyers log in and see their own catalog, prices and terms, reorder from past orders and pay by invoice or card. Your sales team keeps visibility of every account in the Shopify admin, while the ERP remains the system of record for credit limits and invoicing.
How we replatform enterprise stores to Shopify Plus
We replatform enterprise stores to Shopify Plus with a migration plan that protects revenue, data and search rankings. Products, customers, order history, gift cards and URLs are mapped, test-migrated and verified before the cutover.
- Audit: inventory every custom feature, extension and integration on the current platform and decide whether to rebuild, replace or retire it.
- Data mapping: define how products, attributes, customers, orders and content translate to Shopify's data model and metafields.
- Test migrations: run repeated imports into a staging store and reconcile counts, prices and customer records.
- SEO protection: map every indexed URL to a 301 redirect and carry over metadata and structured data.
- Cutover: freeze, run a final delta migration and switch DNS with no storefront downtime.
Our Magento to Shopify migration service follows this approach, and the outcomes are measurable. In our Magento to Shopify Plus migration case study, a luxury apparel brand moved from a Magento monolith to a headless Next.js and Shopify Plus stack, unified 8 regional stores, increased mobile conversion rate by 142% and reached a 0.6-second average page load.
Shopify Plus development cost and timeline
Shopify Plus projects with custom features typically sit in the $25,000–$60,000 range, while headless, multi-region or B2B-heavy builds run $60,000–$150,000+. Delivery usually takes 8–16 weeks under fixed-price milestones.
| Phase | Typical weeks | Shopify Plus focus |
|---|---|---|
| Discovery & Strategy | 1–4 | Plus feature mapping, store architecture, integration and migration plan |
| Conversion UX/UI Design | 1–4 | Theme or headless design system, checkout and B2B account flows |
| Architecture & API Engineering | 5–12 | ERP, PIM and OMS integrations, Functions and extension design |
| Custom Development | 5–12 | Storefront, checkout extensions, custom apps and Flow automations |
| Testing & Optimization | 13–16 | Load testing, data verification, Core Web Vitals and accessibility |
| Zero-Downtime Launch | 13–16 | Staged cutover, redirect checks and hypercare monitoring |
Budget sits mainly in integrations, custom Functions and apps, and the number of storefronts at launch. Shopify's own Plus subscription is billed separately by Shopify, and we include it in the total cost of ownership model we prepare during discovery.
