Our stack
E-commerce technologies we use
We pick the right platform and tools for your product and growth goals.
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.
