The problem
Your platform should grow sales — not slow you down
Themes and apps only go so far
Off-the-shelf themes and app-store plugins cover most of what you need. The last mile — custom checkout rules, B2B pricing, bundles — needs real development.
Data that doesn't sync
Products, stock, and orders drift between your store, ERP, warehouse, and marketplaces because the integration was never built properly.
Slow, heavy storefronts
Too many apps and scripts drag mobile page speed down — and slow pages lose both conversions and rankings.
No one who knows the API
Shopify GraphQL, BigCommerce REST, WooCommerce, and Wix APIs change often. Generalist freelancers learn on your budget.

FAQ
eCommerce platform development FAQ
Which eCommerce platforms do you develop for?
Shopify, BigCommerce, WooCommerce (WordPress), Wix, Squarespace, Square Online, and Odoo eCommerce. We work with each platform's own APIs — including the Shopify Storefront and GraphQL Admin APIs, the BigCommerce REST and GraphQL Storefront APIs, the WooCommerce and WordPress REST APIs, and the Wix, Squarespace, and Square APIs.
Do you build headless Shopify and headless BigCommerce stores?
Yes. We build headless storefronts on modern web frameworks that read from the Shopify Storefront API or the BigCommerce GraphQL Storefront API, while you keep managing products, orders, and payments in the platform admin.
Can you build a custom Shopify or BigCommerce app?
Yes. We build custom and private apps for features the app stores don't cover — ERP or warehouse sync, custom pricing rules, automated catalog updates, and internal dashboards.
Can you connect my store to marketplaces, an ERP, or Odoo?
Yes. We build two-way syncs for products, inventory, orders, and tracking between your store and marketplaces, ERPs such as Odoo, accounting tools, and fulfillment providers.
Do you work with clients in the US, Europe, and the Middle East?
Yes. Netalith works remotely with individuals, online sellers, and businesses worldwide — including the United States, the EU and UK, the Middle East, Canada, and Latin America. We communicate in English by email, chat, or scheduled calls in your time zone.
How much does eCommerce platform development cost?
Every job is quoted on its actual scope — a focused fix costs far less than a full build. Send us your requirements and we'll reply with a scope and a fixed price, usually within 24–48 hours, before any work begins.
