TL;DR — For most US mid-market merchants, the best e-commerce website developers are senior WordPress/WooCommerce agencies (for catalog-heavy stores), Shopify Plus partners (for fast launches and aggressive scaling), or headless commerce specialists (for custom storefronts on Next.js or Astro). Expect $30,000-$120,000 for a custom build and $80-150/hour for ongoing development. Belov Digital is a certified WooExpert with 200+ WooCommerce stores shipped since 2012.
What “best” actually means for e-commerce developers
“Best” depends on three things: (1) the platform your store will run on, (2) the developer’s depth on that platform, and (3) how the engagement model fits your growth plan. A WooExpert is the right answer for a 5,000-SKU specialty retailer. A Shopify Plus partner is the right answer for a DTC brand chasing a fast launch. A headless commerce shop is the right answer when your roadmap includes a custom checkout flow, a mobile app, or international expansion with locale-specific storefronts.
7 criteria for picking an e-commerce developer
- Platform certification. WooExpert (Automattic-vetted), Shopify Plus Partner, BigCommerce Elite Partner. These are publicly verifiable.
- Stores shipped on the actual platform you’ll use. Not generic “200 websites” — specifically Woo or Shopify or BigCommerce stores. Ask for 5 case studies.
- Payment, tax, and shipping integration experience. Stripe, Authorize.net, Avalara, ShipStation, EasyPost. These are where complex builds break.
- Performance track record. Mobile Core Web Vitals scores on existing stores. Aim for LCP under 2.5s, INP under 200ms.
- Maintenance and post-launch capability. A new store breaks within 60 days if the dev team can’t keep up. Ask about retainer pricing.
- In-house vs subcontracted. Agency-of-agencies markup is real. Ask explicitly: “Who codes my project — your employees or freelancers you sub to?”
- Engagement model fit. Fixed-fee for a defined scope, hourly for ongoing improvement, hybrid for long-term partnership. Match this to your roadmap.

When Belov Digital is the right choice
We’re a senior WooCommerce development agency and a certified WooExpert. We’re the right fit when you need:
- A custom WooCommerce build from scratch (not a child of Storefront, not a Page Builder duct-tape job)
- Migration from Shopify, BigCommerce, or Magento to WooCommerce with full product, order, and customer data preservation
- Custom payment, subscription, or multi-vendor marketplace logic
- Long-term maintenance and conversion-improvement work after launch
- Hourly engagement at $80-120/hour instead of fixed-fee scope traps
We’re not the right answer if you need a Shopify Plus launch in 4 weeks or a fully custom headless commerce build on a $300K budget. We’ll tell you that on the first call.
Frequently asked questions
Who are the best WooCommerce developers in the US?
Top-tier US WooCommerce developers are typically Automattic-certified WooExperts. Belov Digital, Saucal, Storefront, and a handful of others maintain WooExpert certification and have shipped 100+ production stores.
How much does a custom e-commerce website cost in 2026?
A custom mid-market e-commerce build typically runs $30,000-$120,000 depending on the catalog size, custom payment/subscription logic, integration depth, and design fidelity. Headless or fully custom builds start at $80,000+.
Should I pick WooCommerce or Shopify in 2026?
WooCommerce wins for content-heavy stores, full data ownership, no transaction fees, and complex customizations. Shopify wins for speed of launch, hosted infrastructure, and integrated payment processing. We build both and recommend honestly based on your roadmap.
How long does it take to build a custom e-commerce website?
Most mid-market WooCommerce or Shopify builds ship in 8-14 weeks from signed proposal. Headless or fully custom builds run 12-24 weeks. Freelance-scope projects under $15K typically ship in 4-8 weeks.
What’s the difference between a WooExpert and a regular WooCommerce developer?
WooExpert is a certification program run by Automattic (WooCommerce’s parent company) that vets agencies based on portfolio, code quality, and track record. WooExperts get direct escalation to WooCommerce’s engineering team and early access to upcoming features.
