Ecommerce Solutions

Every ecommerce build type, done properly.

Shopify Custom Development

Custom Shopify themes, Shopify apps, metafields-driven storefronts, Shopify Plus customisations, and checkout extensions. Shopify is the right platform for most D2C retailers, and we make it work exactly the way you need.

WooCommerce & BigCommerce Development

Custom WooCommerce themes, plugins, and integrations, plus BigCommerce storefronts and apps. KometCode has delivered BigCommerce stores for Canadian retailers with Canada Post shipping, provincial tax rules, POS-compatible setups, and local SEO fully configured.

Odoo Ecommerce

Odoo Website Commerce tightly integrated with your Odoo ERP so inventory, orders, and customer data live in one system with no sync required. Ideal for manufacturers and distributors already on Odoo.

Headless Commerce

Next.js or Astro frontend connected to Shopify, BigCommerce, WooCommerce, or a custom backend via API. Maximum performance and flexibility for storefronts that platforms cannot deliver out of the box.

B2B Ecommerce Portals

Customer-specific pricing, tiered accounts, purchase order workflows, and invoice management for wholesale and distributor ecommerce. Different from D2C, and we build for both.

ERP + Ecommerce Integration

Connect Shopify, BigCommerce, or WooCommerce to your ERP for real-time inventory, order sync, and automated invoicing, eliminating manual data entry across systems.

Multi-Market Ecommerce

Ecommerce for Canada, the US, and global markets.

KometCode builds ecommerce for clients worldwide. For Canadian and US markets, we configure provincial and state tax rules, Canada Post and UPS integrations, Interac and credit card payment processing, and bilingual (EN/FR) requirements for Quebec. We deliver these capabilities alongside global storefront and ERP integrations.

  • GST/HST/PST by province: fully configured tax rules
  • Canada Post API: live shipping rates and label generation
  • Interac, Stripe Canada, Square: payment gateway setup
  • US state sales tax: Shopify Tax or TaxJar integration
  • Canada-wide and US delivery: zone-based shipping configuration
  • Local SEO setup: Google Business Profile and on-page optimisation

Case Study

KometCode redesigned a Windsor vape retailer's BigCommerce storefront (50% sales increase in 3 months), then built a convenience retailer's store from scratch on the same platform for POS compatibility and team familiarity — plus local SEO, Google Business Profile, social media, and Canada-wide shipping.

FAQ

Frequently Asked Questions

Shopify and WooCommerce are excellent for standard retail. Choose custom ecommerce when you need unique checkout flows, complex B2B pricing or account structures, deep ERP integration, headless storefronts, or product configurators that platform tools cannot support.

Yes. We build custom Shopify themes, Shopify apps, metafields-driven storefronts, and complex Shopify Plus customisations for retailers worldwide, including Canadian and US markets.

Yes. KometCode regularly integrates ecommerce platforms (Shopify, WooCommerce, custom storefronts) with Odoo ERP, including inventory sync, order management, and customer data flows. We have case studies covering this exact integration.

A WooCommerce or Shopify custom storefront typically takes 6–12 weeks. A fully custom headless ecommerce platform with API design, PIM integration, and payment flows runs 3–6 months.

Cost depends on platform, feature scope, and integrations. KometCode has delivered ecommerce projects for Canadian convenience retailers and global brands at significantly lower cost than local agency rates. Contact us with your store requirements for a scoped estimate.
