Frequently Asked Questions

Common Technical Questions Answered

How long does a custom Shopify or WordPress development project take?
Typical timelines: Custom Shopify theme (3–5 weeks), WooCommerce build (4–6 weeks), full React/Next.js web app (6–10 weeks). Complex headless or multi-channel builds are scoped individually. All projects begin with a signed scope document before development starts.
Shopify excels for pure e-commerce operations — faster launch, lower hosting overhead, and a robust app ecosystem. Headless React is ideal for enterprise brands demanding sub-second page transitions and custom frontend UX. WordPress/WooCommerce is best for content-rich brands that need complex catalog custom fields and total database ownership. We recommend the right stack based on your catalog size, revenue model, and growth targets.
Yes. Every project includes an automatic 30-day post-launch warranty covering any critical bugs. We also provide ongoing monthly retainer packages covering core updates, server health monitoring, security audits, database cleanups, and priority developer hours.
Absolutely. All platform migrations include a full URL redirect mapping, canonical tag audits, structured data re-implementation, and a 301 redirect plan to preserve domain authority. We track organic traffic before and after to confirm zero ranking regression.
Our complimentary web audit evaluates: Core Web Vitals (LCP, INP, CLS), mobile responsiveness, checkout flow friction points, SEO technical health (meta, canonical, sitemap), page speed bottlenecks, and conversion UX gaps — delivered as a prioritized action report within 48 hours.
