Development FAQ
Common questions about building on Shopify.
How long does a typical project take?
A custom Shopify store usually takes 4–8 weeks depending on design scope, integrations and catalog size. We confirm timeline after discovery.
Do you work with Shopify Plus?
Yes. We build on Shopify Plus: custom checkout, Scripts, B2B, multi-store and enterprise integrations.
Can you redesign my existing Shopify store?
Yes. We migrate to a new theme or rebuild sections while preserving SEO, apps and order history.
Do you build custom apps?
Yes — private apps for inventory sync, workflows, middleware and features that off-the-shelf apps do not cover.
How much does Shopify development cost?
Depends on scope. Starter stores from ~$1,500; custom themes with integrations typically $3,000–$15,000+. We quote after a short brief.
Do you provide support after launch?
Yes. We offer maintenance retainers, feature sprints and priority support for critical issues.
