E-commerce Development Services Built Around Your Catalog, Checkout, and Delivery
We build custom online stores and shopping apps for teams whose product catalog, checkout flow, or delivery logistics don't fit a standard template. Our e-commerce development covers everything from product search and filtering to payment gateways and carrier integrations. For KANTORA, a mobile fashion e-commerce app, we built the catalog, product cards, filters, cart, and a checkout flow with Nova Poshta delivery integration for the Ukrainian market.
When companies come to us for e-commerce development
An existing store is stuck on a rigid platform or template. The catalog structure, checkout, or design can't flex the way the business needs, and every small change turns into a workaround.
A custom checkout or delivery integration a generic platform can't handle. Some carriers, tax rules, or fulfillment flows aren't supported by off-the-shelf tools, so the integration has to be built directly.
Launching a new online store or shopping app. The business is starting fresh and wants the catalog, cart, and checkout built around how customers actually shop, not a generic template.
Cart abandonment or performance issues are hurting sales. Slow product pages, a clunky checkout, or a confusing filter system are pushing shoppers away before they buy.
E-commerce development services we provide
- Product catalog & search/filtering
- Structured catalogs with fast search, faceted filters, and category navigation that scale as the product range grows.
- Cart & checkout flow
- A cart and checkout built to reduce friction and drop-off, from guest checkout to saved addresses and order review.
- Payment gateway integration
- Secure integration with the payment providers your market needs, including card, wallet, and local payment methods.
- Delivery & logistics integration
- Direct integration with carriers and fulfillment systems. For KANTORA, we integrated Nova Poshta so customers could select delivery options and track orders within the app.
- Mobile shopping app development
- Native and cross-platform shopping apps with the same catalog, cart, and checkout logic as your web store, tuned for mobile use.
- Order management & admin tooling
- Admin dashboards for managing inventory, orders, and fulfillment status, so your team isn't relying on the platform's default back office.

Frequently asked questions
What does an e-commerce development company actually build versus what a platform like Shopify gives you out of the box?+
A platform gives you a template for catalog, cart, and checkout that works for common cases. We build the parts that don't fit that template: custom filtering logic, non-standard checkout flows, or delivery integrations a platform doesn't support, like Nova Poshta for KANTORA.
How long does custom online store development take from discovery to launch?+
It depends on catalog size, the number of integrations, and whether you're building a web store, an app, or both. A scoped estimate comes out of the discovery phase once we understand your specific requirements.
Can you integrate a specific delivery carrier like Nova Poshta into an existing store?+
Yes. We built a Nova Poshta delivery integration for KANTORA, letting customers select delivery options and get order tracking directly in the app. We can do the same for other carriers depending on your market.
Do you build shopping apps for iOS and Android, or only web stores?+
Both. KANTORA is a mobile fashion e-commerce app with catalog, product cards, filters, cart, and checkout. We also build web stores, and can build both from a shared catalog and checkout foundation.
What causes most cart abandonment, and how do you address it during development?+
Slow pages, confusing checkout steps, and forced account creation are common causes. We design the checkout flow to minimize steps and friction, and test performance on the product and cart pages before launch.
Do you offer support after the store or app launches?+
Yes. Our process includes post-launch support for fixes, monitoring, and ongoing iteration as your catalog, traffic, or integrations change.
