Why Chicago Brands Choose FactoryJet E-Commerce
We replace fragile app-stacked storefronts with clean engineering and automated ERP workflows:
Ending App-Stack Bloat & Mobile Cart Abandonment
Standard Shopify agencies install 30+ recurring monthly subscription apps that conflict with each other, slow down page speeds, and cause cart checkout crashes.
We engineer custom Liquid and TypeScript components natively into your theme, eliminating bloated third-party apps while cutting monthly software overhead.
Eliminating Manual Order Entry & ERP Inventory Disconnects
Operating disjointed ecommerce platforms forces customer service teams to manually re-enter orders into NetSuite or SAP, causing shipping delays and stockouts.
We construct resilient bidirectional middleware synchronizing inventory counts, customer pricing, sales orders, and tracking updates in real time.
Replacing Outdated B2B Phone & Fax Orders with Self-Service Portals
Wholesale buyers in the Chicago industrial corridor expect self-service digital portals with custom account terms, volume pricing, and reorder pads.
We build enterprise B2B wholesale portals with company account hierarchies, purchase order terms (Net 30/60), and one-click repeat ordering tools.
Preventing Catastrophic Traffic Drops During Ecommerce Migrations
Replatforming from Magento or WooCommerce without meticulous technical SEO planning causes 404 errors, loss of keyword rankings, and immediate revenue drops.
We execute 100% URL-by-URL redirect mapping, preserve canonical metadata, and inject structured Product JSON-LD schema to maintain and grow search revenue.

Topics
Can’t find your answer?
Talk to the founderPlatforms & Tech
Why should a Chicago business choose Shopify Plus over Magento or custom legacy platforms?
Legacy platforms like Magento (Adobe Commerce) or outdated WooCommerce setups demand substantial ongoing server maintenance, security patching, and expensive DevOps overhead. Shopify Plus delivers 99.99% uptime, infinite elasticity during holiday volume spikes, native multi-currency support, and the highest-converting checkout in commerce (Shop Pay) while reducing total cost of ownership by up to 60%.
What is headless commerce and is it right for our brand?
Headless commerce decouples the frontend user experience (built in Next.js and React) from the backend commerce engine (such as Shopify Plus). It delivers sub-second page loads, limitless design flexibility, and dynamic omnichannel experiences. It is ideal for high-growth brands with complex product configurators or multi-region flagships.
Do you build custom subscription billing workflows?
Yes. We integrate native subscription engines like Recharge, Smartrr, or custom Shopify Subscriptions API workflows, allowing customers to easily manage recurring orders, swap products, and adjust delivery frequencies from a frictionless customer portal.
Can our store support multi-currency and international cross-border sales?
Yes. Using Shopify Markets or BigCommerce Multi-Storefront, we configure localized currencies, automatic geo-IP redirection, duties and import tax calculations at checkout, and localized language storefronts.
Can you create custom product configurators or customizer tools?
Yes. We build high-performance 2D and 3D product configurators using WebGL and modern React, allowing customers to customize colors, engravings, dimensions, and materials with real-time price updates.
How do you architect headless Shopify storefronts using Next.js 15 and GraphQL Storefront API?
We build decoupled frontend applications utilizing Next.js 15 App Router, React Server Components, and Tailwind CSS. The storefront connects to Shopify Plus via the GraphQL Storefront API and Customer Account API, achieving instantaneous page loads (<200ms TTFB), total UX design freedom, and complete elimination of liquid theme constraints.
B2B Wholesale
How do you engineer B2B wholesale capabilities on Shopify Plus?
We utilize Shopify Plus B2B features alongside custom middleware to implement tiered contract pricing, custom payment terms (Net 30/60), company account hierarchies, purchase order processing, quantity price breaks, and gated product catalogs, allowing you to run B2B and DTC operations fluidly from a single admin backend.
How do you handle shipping calculations for heavy freight and LTL shipments in Chicago?
For industrial B2B and machinery distributors, we integrate custom freight rate calculators (such as FreightClub or ShipStation Carrier API) to provide real-time LTL shipping quotes based on pallet dimensions, weight, and destination commercial loading dock attributes.
What is PunchOut e-procurement (cXML/OCI) integration for Chicago B2B distributors?
PunchOut e-procurement enables corporate enterprise buyers (such as Fortune 500 manufacturers and healthcare systems) to access your e-commerce product catalog directly from within their internal procurement ERP systems (Ariba, Coupa, Jaggaer). Orders, contract pricing, and requisitions transfer fluidly via cXML and OCI protocols without manual purchase order entry.
What are the core capabilities of BigCommerce B2B Edition for Illinois manufacturers?
BigCommerce B2B Edition provides native corporate account hierarchies, multiple tier-level buyers with custom spend thresholds, requisition list sharing, automated RFQ quote management, and frictionless invoice portal payments. We configure these modules to streamline complex B2B wholesale transactions across Illinois and Midwest regional accounts.
ERP & Integrations
Can you integrate our Chicago ecommerce store with NetSuite or SAP ERP?
Yes. We build resilient, bidirectional API integrations connecting your storefront with NetSuite, SAP, Acumatica, Microsoft Dynamics, or custom ERP systems. This synchronizes inventory counts, customer-specific pricing matrices, sales orders, customer credits, and fulfillment tracking numbers in real time.
What analytics and revenue tracking tools do you configure before launch?
We configure server-side Google Analytics 4 (GA4) e-commerce tracking, Google Tag Manager, Meta Conversions API (CAPI), Pinterest Tag, TikTok Pixel, and Klaviyo revenue attribution to ensure complete data accuracy.
Can you integrate third-party marketplaces like Amazon, Walmart, and Target Plus?
Yes. We connect multichannel catalog feeds and inventory management systems to synchronize stock levels, pricing, and orders across your central Shopify admin and third-party marketplaces.
How do you handle sales tax compliance for multi-state ecommerce sales?
We integrate automated sales tax calculation engines such as Avalara AvaTax, TaxJar, or Shopify Tax to ensure accurate economic nexus tracking and real-time sales tax collection across all US jurisdictions.
How does real-time ERP inventory reconciliation work with NetSuite and SAP in Chicago warehouses?
We build bi-directional API middleware using Celigo, Boomi, or custom Node.js serverless functions that synchronize inventory levels, purchase orders, customer trade balances, and tracking numbers between your warehouse ERP (NetSuite, SAP, Microsoft Dynamics 365) and storefront in sub-second intervals, preventing multi-channel overselling.
How do you structure Product and Offer Schema.org JSON-LD for AI search engines?
We embed granular Product, AggregateOffer, MerchantReturnPolicy, and ShippingDetails JSON-LD schema markup on every product page. This allows Google Merchant Center, Gemini AI Overviews, and ChatGPT to instantly parse live stock availability, tiered pricing, and return terms for organic shopping citations.
Migration & SEO
How do you prevent organic search ranking drops during an ecommerce replatforming?
We execute a comprehensive 1-to-1 URL redirect map for every legacy product, category, and blog URL. We preserve title tag structures, breadcrumbs, and image alt text, while injecting rich Product, Organization, and Offer JSON-LD schema to maintain and enhance your organic search visibility.
Can you migrate our historical customer data and order history from WooCommerce or Magento?
Yes. We extract, sanitize, and migrate complete customer databases, past order histories, product variants, metafields, customer reviews, and category structures with zero data loss.
Pricing & Scope
How much does an enterprise ecommerce development project cost in Chicago?
Project investments depend on catalog complexity, custom UI requirements, B2B wholesale scope, and ERP integration depth. We provide fixed-price milestone contracts with transparent scopes and zero surprise fees. Every proposal includes full UX design, custom development, data migration, and launch warranty.
Do you offer ongoing conversion rate optimization (CRO) retainers after launch?
Yes. We provide monthly growth retainers focused on continuous A/B testing, heatmap analysis, checkout funnel optimization, new landing page development, and retention email marketing.
How long does a complete enterprise ecommerce redesign and launch take?
Standard custom Shopify Plus builds take 6 to 8 weeks from initial design to production deployment. Complex enterprise projects with multi-system ERP integrations and large custom catalog migrations typically require 8 to 12 weeks.
Do we own all custom theme code and design assets upon completion?
Yes, 100%. You receive complete ownership of all custom theme code, GitHub repositories, Figma source design files, and backend configurations with zero recurring agency royalties.
How do we get started on an ecommerce project with FactoryJet in Chicago?
Schedule a discovery consultation or request an enterprise ecommerce architecture review. We will evaluate your current tech stack, identify conversion bottlenecks, and provide a clear roadmap and fixed-price proposal within 24 hours.
Speed & Conversion
How do you optimize mobile conversion rates for Chicago ecommerce stores?
We optimize every touchpoint: instant product variant switching, sticky Add-to-Cart buttons, high-speed mobile search with instant autocomplete, slide-out cart drawers with free-shipping progress bars, and one-tap checkout via Apple Pay and Shop Pay.
How do you ensure our ecommerce storefront remains fast with hundreds of products?
We avoid bloated third-party apps by writing clean native Liquid and React code. We implement responsive WebP image pipelines, server-side caching, and asynchronous script loading to guarantee sub-second catalog browsing and 90+ Core Web Vitals scores.
What is the difference between custom Shopify Liquid themes and pre-built commercial theme templates?
Pre-built commercial themes carry thousands of lines of unused JavaScript, heavy slider scripts, and generic CSS bloat designed for thousands of unrelated stores, frequently scoring 35-55 on mobile Google Lighthouse. Custom FactoryJet themes are engineered specifically for your brand’s exact conversion architecture, containing zero bloat, scoring 90+ Core Web Vitals, and converting 20-40% higher.
