Ecommerce Software Development — Custom Stores That Convert

Most projects land between $25K and $90K for a DTC storefront with 50-500 SKUs, custom cart logic, and Stripe checkout. Enterprise catalogs with B2B pricing, multi-region shipping, and ERP integrations push into the $120K-$200K range. The variable isn't page count — it's checkout complexity and integration depth. We scope every project in a paid discovery phase (usually $3K-$5K) so you get a fixed quote before committing to the full build. You'll walk away from discovery with an architecture doc and line-item estimate either way.

A typical DTC storefront with under 200 SKUs ships in 6-8 weeks from kickoff. Larger catalogs with custom filtering, B2B pricing tiers, or third-party integrations (ERPs, 3PLs, loyalty platforms) take 10-14 weeks. We've never missed a Black Friday deadline — we plan launches with a two-week buffer and run load tests at 10x projected traffic before cutting over.

Shopify Liquid themes are server-rendered by Shopify's infrastructure, which means you don't control caching, you can't use server components, and every app you install adds its own JavaScript bundle. A headless Next.js storefront on Vercel gives you edge rendering in 70+ regions, sub-second LCP on mobile, and a React codebase your team actually wants to work in. We've measured 18-35% conversion rate lifts when migrating brands from Liquid themes to headless — most of that comes from speed alone.

If your team already uses Shopify for inventory management, fulfillment, or POS, we'll keep Shopify as the backend and build headless against the Storefront API. You keep your ops workflow and ditch the slow theme. If you're starting fresh or want to avoid Shopify's transaction fees and app ecosystem costs, Medusa.js gives you a fully open-source commerce engine you self-host. We deploy Medusa on Railway or Fly.io with Supabase as the data layer. Either way, the storefront code is identical — Next.js doesn't care what's behind the API.

A typical project runs with a lead engineer (senior full-stack, Next.js + commerce APIs), a frontend engineer focused on storefront UI and animations, and a project lead who handles timelines, client communication, and QA. For larger builds we'll add a backend engineer for ERP/3PL integrations and a dedicated QA engineer. You'll have a shared Slack channel and weekly async video updates — we don't do status meetings that could've been a Loom.

Yes. Every storefront we ship hits 90+ on Lighthouse for Performance, Accessibility, Best Practices, and SEO — measured on mobile, in production, with real product data and images. We test against your actual catalog, not placeholder content. If scores drop below 90 within 30 days of launch due to our code, we fix it at no cost. We also hand off a performance monitoring dashboard so your team can catch regressions before customers do.

We've migrated stores with 50K+ SKUs and active order volumes without a single minute of downtime. The process involves running the new storefront in parallel on a staging domain, syncing product and customer data via background jobs, then cutting DNS during a low-traffic window. Existing orders, customer accounts, and subscription data carry over. We typically run both systems in parallel for 48-72 hours post-launch as a safety net.

We offer monthly retainer plans starting at $3K/month for ongoing feature development, performance monitoring, and infrastructure management. Most ecommerce clients use 15-25 hours/month for things like new landing pages, A/B test implementations, seasonal promo logic, and Stripe billing changes. You'll also get a full handoff package at launch: codebase docs, environment setup guides, deployment runbooks, and recorded walkthroughs so your internal team can ship changes independently if you prefer.
