If a hosted platform like Shopify or WooCommerce can handle your catalog, checkout, and shipping logic out of the box, custom development is usually the wrong call — you'll pay more to rebuild what a platform already does well. Custom development earns its cost when your business has requirements a platform genuinely can't meet: complex pricing rules, a non-standard inventory model, tight integration with an existing internal system, or a checkout flow that needs to do something a plugin can't.

A lot of "custom e-commerce" requests are actually platform-plus-integration work — a Shopify storefront wired into a custom inventory API, for instance — which costs less than a fully custom build and ships faster.

Payment integration (typically via Stripe) is usually the most technically sensitive part — checkout, webhooks for order status, refund handling, and tax calculation all need to work correctly the first time, since bugs here cost real money. Product catalog complexity is the second driver: a simple product list is cheap to build, but variants, bundles, or configurable products add real scope.

For a scoped custom storefront with standard checkout, fixed-price work starts from USD 500 and scales with catalog complexity and integrations. Hourly work runs USD 25–45/hr with a 10-hour minimum, which suits a build where requirements are still being finalized alongside inventory and fulfillment decisions.

Budget for ongoing maintenance separately from the initial build — payment provider APIs change, security patches need applying, and a storefront that stops getting updates becomes a liability over time, not just a stale asset. A retainer arrangement, starting from USD 800/month, is a common way to keep a store maintained without re-negotiating a new contract every time something needs fixing.
