What We Deliver

Our ecommerce development services combine product design and delivery in one team for web and mobile app development. The scope is defined for your web and mobile product, from early decisions through launch and post-release work.

Product strategy and UX

Turn your ecommerce idea into a product roadmap, buyer flows, and a clear delivery scope. We define the shopping journey through project discovery, UI/UX design, prototyping, web design, and UX audit before development begins.

Web and mobile ecommerce app development

Build web and mobile ecommerce apps with the technologies agreed for your scope, including React Native and React.js. Our development and quality assurance work covers core shopping flows, release preparation, and testing through each delivery iteration.

Product improvement and support

Write product UX copy for onboarding, interface prompts, and customer-facing flows. After release, our maintenance service covers agreed fixes and improvements. Product feedback and priorities shape the next development stage.

Expertise and team extension

Use our 9+ years of experience and portfolio to make product decisions before development. When a project needs additional capacity, we add product specialists who work with your team on the agreed ecommerce product scope.

Why work with us on ecommerce development?

Stay involved throughout delivery

Daily and weekly updates, plus regular demos, keep your team close to the work. The current scope stays visible, so product decisions can be made before a change reaches development.

Build around your business context

The ecommerce business model, customer journey, and delivery constraints shape the product from the start. Our portfolio shows the range of products we have delivered.
300 projects

Adjust scope with a shared plan

When priorities change, we discuss the effect on scope and timing before moving forward. That keeps product decisions connected to the delivery plan instead of treating every new request as automatic.

Our eCommerce development process

1.

Discovery and delivery planning

We start by aligning ecommerce product goals, buyer journeys, and the decisions that shape the estimate. The result is a shared delivery plan with a defined scope, team, timeline, and two-week work cycles, so everyone sees what is being built and when.
2.

Product and interface design

Ecommerce buyer flows are mapped from product discovery through cart and checkout before interface work begins. Those flows become screens, interface elements, and a consistent visual system that gives the development team a clear specification to work from.
3.

Ecommerce application development

The agreed web and mobile ecommerce application is built in delivery increments. Each increment connects the customer-facing experience with the underlying product logic, so progress can be reviewed against the scope rather than only at the end of the project.
4.

Quality assurance and release preparation

Core shopping flows are tested throughout development, from browsing and checkout to the areas agreed for the product. Before release, the team resolves issues and prepares the product for desktop, mobile, App Store, or Google Play distribution when those channels are in scope.
5.

Launch and continued improvement

The release stage draws on the experience of 300+ apps delivered for our clients. After launch, product feedback and technical issues inform the next agreed improvements, maintenance work, and feature priorities.

Influence the cost of eCommerce development

Core features

The number and complexity of features shape the estimate. Ecommerce platform requirements for the product catalog, cart, checkout, and inventory are assessed together with the payment gateway setup.

Project timeline

A shorter delivery timeline requires more capacity at the same time. The estimate reflects the schedule agreed for your scope.

Platform choice

The platform mix affects the work required. An ecommerce website, native iOS or Android app, and cross-platform product have different design and development needs.

Hiring model

Your delivery model affects cost and responsibility. The choice between an in-house team, freelancers, and an agency is assessed against the scope before work begins.

When I had an idea for my startup, I needed to test it quickly with an MVP. I searched for companies that do this, and Purrweb was at the top; I liked how they position themselves. I got very high-quality project management: they organized everything very quickly, we worked in sprints with clear communication and reached a result fairly fast.

Today my project has grown into a small business, MyWard, and we keep working on it. I recommend Purrweb to anyone who needs to test an idea quickly and get a fast, high-quality result.

KEM — Payment app

I'm the CEO of KEM, a P2P mobile payment service for the Kuwaiti market, where not everyone has access to online banking. Our banking partners needed an MVP for demonstrations. Purrweb delivered the design and the MVP, working around the restrictions on connecting to the banking API. On completion, they handed the project over to our in-house team with full documentation and a month of technical support.

KEM — Payment app
Fintech, Design+Development, Mobile app, Cross-platform, MENA

KEM is a P2P app for instant money transfers in the Kuwaiti market: linked bank cards, money requests from the contact list, and transaction history. The key challenge: for security reasons, Kuwaiti banks don't allow outside developers to work with their API — so Purrweb built the back end on mock data, fully simulating the final functionality for demos.
