Custom Shopify Stores That Sell, Not Just Look Good

FactoryJet provides fixed-price Shopify development scoped to your exact catalog. Main cost drivers include custom theme design, catalog migrations, and third-party app setups. Complex builds like Shopify Plus B2B wholesale portals or headless Hydrogen apps require broader scopes. Every build is milestone-paid with clear deliverables confirmed before work starts. You receive senior engineering without agency bloat or surprise hourly invoices.

A custom theme on an existing store takes 2–3 weeks from design sign-off. A full store build from scratch takes 3–5 weeks. Shopify Plus or headless Hydrogen builds run 6–10 weeks depending on B2B complexity or custom app requirements. We give you a firm timeline during discovery, because clear scope drives delivery speed.

We work on a fixed-price, milestone-paid basis. Every build is scoped upfront with no hourly billing and no surprise invoices. Years of building Shopify stores helps us estimate accurately on the first call. The quote you approve is what you pay. You get clean Liquid engineering, high Lighthouse scores, and complete code ownership.

Costs depend on your specific project scope and catalog size. A custom theme build on an existing store costs less than a ground-up migration. We provide a firm fixed quote after your initial discovery call. Freelancers often bill hourly without hard ceilings, which leads to budget overruns. Our milestone-paid structure ensures total cost certainty from day one.

Shopify store costs scale with catalog complexity and design depth. Custom Figma themes require deeper engineering than basic template tweaks. Shopify Plus and headless builds represent the highest enterprise tier. In addition to initial builds, factor in platform fees and app subscriptions. We quote all upfront development costs and expected app expenses before work begins.

Standard Shopify works well for most DTC brands under $2M in annual revenue. Shopify Plus is worth the investment when you need custom checkout extensions, native B2B wholesale pricing, or multi-storefront setups. We evaluate your sales volume during discovery. We never recommend Plus unless your operations genuinely require it.

Headless Shopify decouples your storefront using Hydrogen while keeping Shopify for checkout and inventory. This architecture delivers sub-second loads and bespoke user experiences. Most brands under $5M annually do well on standard Liquid themes. For high-volume brands, a small conversion lift easily covers headless infrastructure costs.

Yes to both. We integrate any Shopify App Store tool into your custom theme. This includes reviews, subscriptions, loyalty programs, and upsells. When public apps lack necessary features, we build custom private apps using the Shopify GraphQL Admin API and Polaris components.

We regularly integrate Klaviyo for email, Yotpo and Okendo for reviews, and Recharge for subscriptions. For fulfillment, we connect ShipStation and EasyPost. For search, we configure Algolia and Boost Commerce. We style every app to match your theme perfectly with zero UI clutter.

Yes, Shopify B2B is a core agency specialization. For Shopify Plus clients, we configure native wholesale features. These include company accounts, custom price lists, net payment terms, and tax resale rules. For standard Shopify, we configure wholesale tools like Wholesale Gorilla or Locksmith. We set up minimum order quantities, volume pricing, and custom reorder pads. Shopify B2B replaces expensive legacy portals with a streamlined checkout.

Yes, recurring subscription stores are a major focus for our team. We integrate platforms like Recharge, Skio, or Bold Subscriptions. Implementation covers subscription product setups, recurring billing schedules, and customer self-service portals. Customers can easily pause, skip, or swap upcoming orders. We also build custom cancel-save flows that recover up to 25% of churn. Klaviyo retention flows keep subscribers engaged over the long term.

We build custom Shopify themes from scratch using clean Liquid and Tailwind CSS. We also customize existing premium themes when a full ground-up build is unnecessary. Our team develops custom sections, connects metafields, and streamlines checkout journeys. You receive clean, modular code that your marketing team can manage easily.

Yes, design and development are integrated into a unified workflow. Our designers create full Figma mockups for desktop and mobile before coding starts. You review and approve every layout, interaction, and responsive breakpoint. This ensures your live storefront matches the approved aesthetic with pixel-perfect precision.

Yes, WooCommerce migrations are a core weekly service. We transfer all products, customer records, and historical orders. We map your historical URL structure and create 1:1 301 redirects for every link. We test transactions on a staging store before DNS cutover to ensure zero downtime.

We migrate stores from Magento, BigCommerce, Squarespace, Wix, and custom databases. Complexity depends on catalog volume, custom metafields, and legacy pricing rules. We clean and format all data before importing it into native Shopify fields.

Yes, when handled with proper engineering, your rankings will stay safe. We crawl your entire legacy domain to document all ranking URLs. We build comprehensive 301 redirect maps and preserve all title tags, meta descriptions, and structured data. We verify indexing in Google Search Console post-launch.

Yes, technical SEO is baked into every theme we build. We configure clean canonical tags, Product schema, and BreadcrumbList markup. We compress images, optimize Web Vitals, and generate automated sitemaps. Your store launches ready to rank for primary commercial keywords.

Our custom Liquid themes consistently score 90–97 on Lighthouse Performance. They achieve 100 on Accessibility, Best Practices, and SEO. Headless Hydrogen builds reach 95+ on Performance. We run live PageSpeed audits before launch so you verify scores upfront.

Shopify has unique technical quirks that amateur developers often miss. These include duplicate variant URLs, pagination dilution, and app script bloat. FactoryJet resolves these issues directly in Liquid code. We also implement full Answer Engine Optimization for AI search engines. We deploy Product schemas with live pricing and availability. We also add FAQPage and BreadcrumbList schemas. This structure helps search engines and AI engines parse your products with high confidence.

Yes, you own 100% of your codebase. We push the entire theme to your private GitHub repository on launch day. Every template, section schema, and asset belongs to your company. Any developer can maintain or update your store in the future without proprietary lock-in.

We offer three distinct advantages: fixed pricing, faster delivery, and direct senior access. Traditional agencies take four to six months and bill hourly. We build custom stores in three to five weeks. You work directly with senior architects who write the actual Liquid code.

Yes, we frequently optimize existing stores without full rebuilds. We audit conversion funnels, fix slow mobile templates, and streamline checkout flows. Often, targeted optimizations on your product pages and navigation deliver major revenue gains without rebuilding from scratch.

High-converting Shopify stores excel across four core areas. First, mobile checkout must be instant with one-tap Apple Pay or Shop Pay. Second, trust signals and reviews must sit prominently near the main CTA. Third, page speeds must load under two seconds on mobile networks. Fourth, post-purchase one-click upsells boost average order value by 15%. FactoryJet implements all four pillars across every custom build.

Every build includes a 30-day post-launch support window for adjustments and questions. After that, we offer flexible monthly retainer plans with dedicated engineering hours. Retainer services include new landing pages, speed audits, app integrations, and promotion setups. We also provide standalone conversion audits 60 to 90 days after launch. You always have direct access to the engineer who wrote your store code.

Yes, we provide dedicated senior Shopify engineers for ongoing work. The same engineer who builds your storefront can support your growth. You avoid handoff friction and maintain technical continuity. We offer monthly blocks of hours for feature updates, seasonal promotions, and performance monitoring.

FactoryJet is purpose-built for growing DTC and B2B brands. We provide senior Liquid engineering, milestone pricing, and fast turnarounds. Brands scaling past $2M often need specialized Shopify Plus features. First-time store launches need speed, clean design, and high mobile conversion. When vetting agencies, review verified Lighthouse scores and actual checkout speed. Real store performance matters far more than generic agency awards.

Many agency roundups focus solely on enterprise shops with massive retainers. FactoryJet focuses on agile mid-market and SMB brands needing top-tier engineering. We provide senior developers, fixed pricing, and rapid delivery. When reviewing agencies, verify who actually writes the code. Ensure they commit to fixed quotes and deliver sub-2s mobile load times.
