Shopify Development Services FAQ
Shopify development services encompass custom theme design, app development, third-party integrations, checkout customization, and performance optimization for Shopify stores. A Shopify development agency like AtlanticWorks builds stores that go beyond templates: creating custom functionality, connecting to ERP and fulfillment systems, and optimizing for conversion. Services range from basic theme customization to full Shopify Plus enterprise implementations with B2B features and multi-store architecture.
Timeline depends on complexity. A basic Shopify store with theme customization takes 2-4 weeks. Custom theme development from scratch takes 6-10 weeks. Full Shopify Plus implementations with ERP integration, custom apps, and data migration typically take 12-20 weeks. We provide detailed project timelines during the discovery phase based on your specific requirements.
Shopify Plus is the enterprise tier offering checkout customization (Checkout Extensibility), Shopify Flow automation, higher API limits (unlimited vs. 2 calls/second), multi-store management, B2B wholesale features, and dedicated support. We recommend Plus for merchants doing over $1M annually, those requiring checkout branding, or businesses with complex B2B requirements. The cost starts at $2,000/month USD but scales with GMV.
Yes. We build private Shopify apps for specific business needs like custom integrations, unique checkout flows, subscription logic, or specialized functionality not available in the app store. We also integrate and configure existing apps from the Shopify App Store, and can build custom admin UI extensions for your team.
Absolutely. We specialize in connecting Shopify with ERP systems (NetSuite, SAP, Microsoft Dynamics), 3PLs (ShipBob, ShipStation, Flexport), and custom warehouse management systems. Integration includes inventory sync, order fulfillment automation, and real-time data flow between systems. See our shipping automation services for more details.
We focus on e-commerce businesses that need more than just a store. Our expertise spans Shopify development, ERP integrations, shipping automation, and marketing. You get one partner for your entire e-commerce stack rather than coordinating between multiple agencies. We're also a certified HubSpot partner, so we can connect your store to CRM and marketing automation.
Shopify development costs vary based on project scope. Theme customization projects start at $5,000-$15,000. Custom theme development ranges from $20,000-$50,000. Full Shopify Plus implementations with integrations typically range from $50,000-$150,000+. We provide detailed quotes after a discovery call to understand your specific requirements and business goals.
Yes. We regularly customize existing themes, add features, improve performance, and fix bugs. If your current theme is limiting growth or causing technical issues, we can assess whether to customize or rebuild. Sometimes a strategic rebuild is more cost-effective than patching an older theme, and we'll give you an honest recommendation.
