How much does it cost to build an eCommerce app?
An eCommerce app is only as good as its conversion rate and load time. The cost is driven by how much of the store is off-the-shelf versus custom, and by everything that happens after checkout — fulfillment, inventory, and support.
In short: An eCommerce app usually runs $8,000–$40,000 and ships in 6 weeks to 4 months. Cost depends on whether you build on Shopify or a custom stack, how complex your catalog and checkout are, and whether you need fulfillment and an admin back office. We build on Shopify when it fits and custom when it does not.
What drives the cost of a ecommerce app
Shopify vs custom
A Shopify-backed app is faster and cheaper when the platform fits. A fully custom store gives you control Shopify cannot, at a higher build cost. We recommend the one that fits, not the one that bills more.
Catalog & checkout complexity
Variants, bundles, subscriptions, discounts, and multi-currency each add work. A simple catalog is cheap; a rich merchandising engine is not.
Payments & fulfillment
Payment providers, tax, shipping, and physical fulfillment integrations add cost — as does the operations tooling to manage orders at scale.
Native app vs web
A mobile shopping app tied to your store captures repeat buyers but adds a build surface on top of the storefront.

Should I build on Shopify or custom?
Both are valid. We build on Shopify when it fits the business — as we did for the Nourriture skincare store and for PocketPrints — and on custom stacks when you need control Shopify cannot give. We recommend the fit, not the upsell.
Can you build a mobile shopping app for my store?
Yes. We built native iOS and Android apps for PocketPrints tied to Shopify and physical print fulfillment. We connect the app to your existing store and fulfillment pipeline.
What drives the price up the most?
Custom checkout logic, subscriptions, multi-currency, and fulfillment integrations. A clean standard store is far cheaper than a heavily customized one — we help you decide what is worth it.
Who owns the store and code?
You do — 100% code ownership, no licensing lock-in, and 30–90 days of post-launch support with every engagement.
