The right platform depends on your product type, catalog size, and growth plans. We help you choose between Shopify (ease of use), WooCommerce (flexibility), or a custom headless solution (performance and scale). We provide a clear recommendation after a free discovery call.

An e-commerce store typically ranges from $15,000–$50,000 for a Shopify or WooCommerce solution. A custom marketplace or headless store can range from $40,000–$200,000+. We provide a detailed fixed-price estimate after a free 1-hour discovery call — no obligations.

Yes. We specialize in integrating e-commerce stores with tools like Salesforce, HubSpot, NetSuite, and custom ERP systems. We'll build the exact data sync you need to keep your operations running smoothly.

A Shopify store typically takes 4–8 weeks end to end. A custom e-commerce solution takes 10–20 weeks depending on feature scope. We work in agile sprints and deliver a staging environment from week one for early feedback.

We build stores with SEO best practices baked in — from schema markup to page speed. We also integrate with marketing tools like Klaviyo, Mailchimp, Google Analytics, and Facebook Pixel to support your acquisition and retention strategies.
