We help Shopify Plus brands launch, scale, and optimize complex eCommerce experiences through custom development, B2B and wholesale solutions, checkout extensibility, integrations, CRO, and retained technical support.
MGROUP brings over 10 years of hands-on experience in eCommerce and Shopify Plus development - helping brands grow through strong technical execution, clear strategy, and practical solutions built for long-term performance.
Custom Shopify Plus development for complex storefronts - bespoke Shopify Plus themes engineered from scratch with clean, modular Liquid code and Online Store 2.0 sections. Built for scaling eCommerce brands that need a maintainable theme architecture, fast Core Web Vitals, and a senior Shopify Plus development team behind every release.
B2B and wholesale workflows with tailored logic - Shopify Plus B2B portals with account-based buying, customer-specific pricing, private catalogs, bulk ordering, quote requests, and approval flows. Wholesale logic that mirrors how your sales team actually closes deals, not a generic Shopify B2B template.
ERP, CRM, subscription, and 3PL integrations for Shopify Plus - connect Shopify Plus with NetSuite, SAP, HubSpot, Salesforce, subscription engines, fulfillment platforms, and PIM systems. Wired in cleanly through Shopify private apps or middleware, with reliable data contracts that replace manual exports.
Shopify Functions and checkout extensibility for Shopify Plus - advanced discount logic, validation rules, payment customizations, delivery customizations, and UI extensions built on Shopify Functions. Modern Plus checkout extensibility replaces legacy Shopify Scripts, with no technical debt left behind.
Ongoing Shopify Plus support after launch - retained access to senior Shopify Plus developers, designers, and CRO strategists. Bug fixes, feature delivery, performance monitoring, A/B testing roadmaps, and continuous Shopify Plus CRO improvements built around your roadmap, not a fixed-scope project.
Smooth collaboration with in-house ecommerce teams - Mgroup works as an external Shopify Plus partner or embedded alongside your internal designers, marketers, product owners, and developers. Transparent delivery, weekly Shopify Plus demos, and clear ownership so your team scales with us, not around us.

MGROUP delivered a well-designed and intuitive website with diverse payment options, which the customers loved. As a result, the company's traffic and sales doubled in record time. The team remarkably collaborated through Slack, Jira, and GitHub. Overall, they were dedicated, flexible, and reliable.
Mgroup was successful in producing Shopify-based websites. The client reported a whopping $500,000 worth of transactions were processed from the site. The team was communicative and responsive throughout the engagement.
Always quick to respond and could easily translate my very poor wireframes into beautiful designs with little direction. I have no doubt I will hire in the future.
The team impressed with their high-quality development skills and the ability to complete all deliverables according to agreed-upon deadlines. While additional communication touchpoints are desired, Mgroup was often able to finish tasks ahead of schedule, moving the project along seamlessly.
