How much does custom ecommerce development cost?
The starting price for our ecommerce development services is shown below. Final cost depends on the number of products, custom features (subscriptions, B2B pricing, ERP sync) and integrations — you get an exact quote with no hidden costs in the free consultation.
How long does an online store take to build?
A standard store is delivered in 2–4 weeks. Custom ecommerce development with bespoke features, headless front-ends or migrations typically runs 4–8 weeks, split into clear milestones so you always know what's next.
Do you work with Shopify or build from scratch?
Both. As a Shopify development agency we ship on Shopify or Shopify headless when it's the fastest path to revenue, and we go fully custom (Next.js, Medusa, custom back-end) when your business needs justify it. We pick the stack that fits, not the one we prefer.
Can I manage products and orders myself?
Yes. You get a clean admin panel and a training session so you can add products, edit prices, run promotions and manage orders without any technical help.
Will the store show up in Google?
Yes. Every category and product page ships with on-page SEO (titles, descriptions, structured data, speed) so your store is ready for indexing and Google Shopping from day one.
