Streaming and social media platforms are packed with content educating on how to launch your online store. Side-hustles or seriousness, tech-savvy users and businesses alike are eager to jump on this gravy train. Why?
A study by Shopify showed that global e-commerce sales are forecast to grow from $6.42 trillion in 2025 to $7.89 trillion by 2028.
There is a visible shift among U.S. shoppers from offline to online shopping. Convenience, price point, and time savings, among other factors, all contribute to the surge in online shopping.

Already convinced which platform is the best for you?
If you want to know the attributes of the aforementioned tools, read on.
The US market is large, regulation-heavy, fast-moving, and highly competitive. And that means your e-commerce platform should do more than just “support transactions.” In 2026, cross-border e-commerce solutions should support scale, reliability, and velocity.
Look at these critical factors before investing:
You should consider:
Why? Well, because peak-season failures are unforgivable in this market.
US sales tax is complex. ADA accessibility is enforced. And, data privacy rules vary among platforms. You should consider robust e-commerce platform features and frictionless integrations to stay compliant without building everything in-house.
If you’re running multiple storefronts, selling across regions, or managing a large number of SKUs, you should consider the platform’s scalability. It must scale horizontally without constant patching or plugin dependency.
Modern US commerce requires seamless integrations to ERPs, CRMs, 3PLs, CDPs, marketplaces, and marketing systems. The platform should offer robust APIs, webhooks, and event-driven integrations.
For successful expansion into US markets, brands should focus on delivering faster and more personalized experiences. E-commerce platforms that support headless, composable architecture are preferred.
US consumers expect one thing above all; a frictionless checkout.
Hence, you should consider support for Apple Pay, BNPL, PayPal, and localized tax/shipping rules in the e-commerce platform you’re choosing.
The following are some of the best players for the 2026 US e-commerce market expansion, each with different strengths and features depending on various things:

WooCommerce and Shopify remain the largest players in the overall e-commerce market. But for brands expanding into the US market in 2026, BigCommerce has emerged as a leading scalable alternative with stronger built-in features, enterprise readiness, and better long-term flexibility.
Emerging e-commerce platforms offer greater scalability, modern architecture, and stronger native features, such as headless and composable commerce. Unlike Shopify and WooCommerce, options such as BigCommerce, Commercetools, and Adobe Commerce are engineered to support faster performance, deeper integrations, and long-term growth in the US market.
Choose SaaS if you want faster setup, reliable performance, and lower maintenance. Choose open-source if you need complete control, deep customization, or complex architecture. The right choice ultimately depends on your technical resources, budget, and long-term growth in the US market.
Key trends include AI-powered personalization, headless and composable commerce, unified online-offline experiences, growth in social commerce, faster fulfillment expectations, and stronger data privacy requirements. These shifts are pushing e-commerce platforms to offer greater flexibility, performance, and integration capabilities for US-focused brands.
Platforms like BigCommerce, Square Online, and Salesforce Commerce Cloud offer some of the strongest US-based integrations, covering taxes, payments, fulfillment, and compliance. They provide localized tools, reliable hosting, and native connections that help brands scale smoothly in the US market.
