The E-commerce challenges we solve
Generic Shopify themes won't cut it
When your brand experience is your competitive advantage, you need a custom-built app — not another theme. We build from scratch with your exact UX in mind.
Mobile shopping is where sales happen
70%+ of e-commerce revenue is mobile. A clunky mobile experience means abandoned carts and lost revenue. We build native mobile apps that convert.
Multi-vendor complexity is real
Marketplaces need seller onboarding, payout logic, inventory sync, and dispute resolution. We've built this stack before — no discovery sprints wasted.

Frequently asked questions
Can you build a marketplace app like Amazon or Airbnb?
Yes. We build two-sided marketplaces with buyer/seller roles, Stripe Connect payouts, listing management, and review systems. We scoped and shipped Porteiro (200+ partners) in 24 days.
Can you integrate with Shopify or existing e-commerce platforms?
Yes. We can build a custom mobile front-end backed by Shopify's Storefront API, or build a standalone app with its own backend. We pick the right architecture for your business model.
How much does an e-commerce app cost?
A focused shopping app MVP starts at $3,460 (fixed price). Multi-vendor marketplaces with seller portals and payout flows are quoted custom — typically $6K–$15K.
