Website Design, Web Development and App Development FAQ

How much does website design and web development cost in Malaysia?
Pricing depends on the number of pages, design depth, CMS requirements, integrations, multilingual content and whether the project is a standard website or a custom web application. UNO scopes each project based on the actual business requirement, so you get a realistic quotation instead of a generic package.
Do you provide website design and web development in Kuala Lumpur?
Yes. UNO is based in Mont Kiara, Kuala Lumpur and provides website design, web development, custom web application, mobile app and ecommerce development services for businesses across Malaysia.
Can UNO build both websites and custom web applications?
Yes. We build corporate websites, CMS websites and custom web applications such as booking systems, customer portals, admin dashboards, approval workflows, reporting tools and business platforms.
Can UNO build iOS and Android mobile apps?
Yes. Our mobile app developer team supports iOS and Android app development, including customer apps, ecommerce apps, loyalty apps, booking apps and internal workforce applications. We also handle backend API integration when the app needs to connect with a website, CRM, ERP or custom system.
Do you provide ecommerce development and shopping cart solutions?
Yes. UNO builds ecommerce websites and shopping cart solutions with product catalogue management, checkout flow, payment gateway integration, order management, promotion logic and reporting.

Do you offer support after the project launches?
Yes. UNO provides post-launch support and maintenance for websites, web applications, mobile apps and ecommerce systems, including troubleshooting, updates, enhancements and third-party issue escalation.
