Web, e-commerce, app and UX/UI services
Duova LLC (Webu) is a digital product studio in Singapore. Four service lines, and the engagement model changes depending on where your product is. Here is what each one covers and how to tell which you need.
Four service lines, one decision
The four lines below cover most of what a Singapore team needs: a marketing site that has to earn trust quickly, a store you own rather than rent from a marketplace, a mobile app that works on both iOS and Android, and a design engagement you can hand to a build team. Read the one that matches your product stage. If two look plausible, the engagement model section tells you how to choose between fixed scope, retainer, and a short discovery.
Marketing sites and platforms
We build sites that have to earn trust quickly. That means information architecture worked out before design, responsive design that holds up on a phone, and a CMS implementation your team can actually operate. Front-end development is done in-house, so the markup you get matches the approved designs.
Corporate platforms, product marketing sites, service-business sites and rebuilds all fall here. If your site is mostly a credibility exercise with a contact form at the end, this is the engagement.
- Information architecture
- Page structure, navigation and content hierarchy agreed before any visual design starts.
- Responsive build
- Mobile-first markup, tested down to 360px and up through large desktop widths.
- CMS handover
- Editable content types, page templates and a short written guide so your staff publish without a developer.
- Front-end fidelity
- Components built against approved designs, documented so your team can extend them later.
Stores you own
WooCommerce on a WordPress base is the standard route for Singapore merchants who want their own storefront rather than a marketplace listing. We handle catalog structure, product page templates, cart and checkout flow, and the admin setup your staff will use daily.
Custom e-commerce work covers cases WooCommerce handles poorly: unusual pricing rules, subscription logic, or a checkout that has to talk to an existing inventory system. We will tell you which side of that line your project sits on before quoting.
Catalog, cart, checkout and admin handover are one scope, not three separate purchases.
Payment and fulfilment methods stay whatever your business already runs — invoice, bank transfer, or payment on pickup. We set up the storefront; we do not take a cut of your orders.
iOS and Android from one build
Cross-platform builds, usually Flutter, for teams that need iOS and Android without maintaining two codebases. React Native stays on the table when your existing team is JavaScript-heavy or the app depends on native modules Flutter wraps awkwardly.
App projects include the design work. A mobile interface has no space to explain itself, so user research and usability testing carry more weight here than on a website, not less.
- Flutter by default when both platforms ship together and you want one codebase to maintain.
- React Native when your in-house team already writes JavaScript and will keep the app after handover.
- Design first in every case: flows, states and empty screens are drawn before build starts.
Design as its own engagement
Plenty of clients come to us with developers already lined up and no design capability. We take on the design half: user research, information architecture, wireframes, prototypes, usability testing, and a design system the build team can implement against.
You own the files when the engagement ends. Handover includes component documentation, not just a Figma link.
If the build team is already hired, the design still has to be written down properly.
Component documentation means the next developer does not re-invent your buttons.
- Research and testing
- Interviews, task testing and findings written so a build team can act on them.
- Wireframes and prototypes
- Flows drawn at the fidelity the decision needs — clickable where behaviour is in question.
- Design system
- Type, spacing, colour and component rules with the states your developers will hit.
- File ownership
- Source files transfer to you at the end of the engagement, documented, not locked away.
Build capacity, nothing else
If you have approved designs and a back end, we convert. Responsive markup, accessibility basics, API wiring, and a written component structure your team can extend. This suits agencies that keep strategy and design in-house and need reliable build capacity.
We ask for the design file and the API documentation before quoting. Both missing means we cannot give you a number that means anything.
- The approved design file With component states, not only the happy-path screens.
- API documentation Endpoints, authentication and the shape of the responses.
- The target browsers and devices So testing matches what your users actually open.
- Who maintains it after launch Changes how much documentation we write into the build.
Custom build or an existing platform
Not every project should be custom. Webflow handles fast marketing sites where the design needs visual fidelity and your team will iterate content often. WordPress suits content-heavy structures. WooCommerce fits merchant-owned stores. A marketplace listing fits small catalogs with tight margins.
Custom development earns its cost when your product logic is the differentiator, or when platform limits would force a workaround you would maintain forever.
Webflow
Fast marketing sites with high visual fidelity and frequent content edits.
WordPress
Content-heavy structures where editors publish weekly and templates repeat.
WooCommerce
Merchant-owned stores with a catalog your staff manage themselves.
Custom build
When product logic is the differentiator, or platform limits would cost you a permanent workaround.
How engagement models differ
All three are legitimate. The wrong one wastes money, usually in the direction of paying for a full build before the scope is understood.
Fixed scope
You know what you want, we quote it, we deliver it. Works best when the requirements are written down and unlikely to move. Changes after sign-off become a separate piece of work, which keeps the original date honest.
Retainer
Ongoing product work where priorities shift monthly. Better for teams already live and iterating than for a first launch.
Discovery only
For teams that need the problem defined before they can budget the solution. Short, and it ends with a scope you can quote against.
What we do not do
Saying no early saves everyone a wasted quarter. These are the three things that come up most often, and where we send people instead.
Templates sold as custom work
If a theme fits your business, buy the theme. We would rather tell you that than rebuild it and bill you for the difference.
Paid media campaigns
We build the destination, not the ad spend. For campaign management, work with a media buyer and we will make the landing pages they point at.
Hosting support as a standalone service
We set up your infrastructure and document it for whoever runs it. Day-to-day hosting management is not an engagement we take on its own.
Before you ask us to quote
Which service line should I pick if I need two of them?
Most projects touch two. A store needs web development and e-commerce work; an app needs mobile and design. We quote them as one scope with the lines itemised, so you can see what each part costs rather than guessing from a single number.
Can you work with an in-house team we already have?
Yes, and it is often the cheapest route. Front-end development only is built for exactly that, and design-only engagements work the same way when your developers are already lined up. We agree who owns which decision before work starts.
What do you need from us to give a real quote?
A short description of what the product does, who uses it, and what already exists — designs, an API, a store, a domain. If you have a deadline that cannot move, say so early; it changes which engagement model we would recommend.
Who owns the code and the design files?
You do, at the end of the engagement. Design handover includes component documentation, and builds include a written component structure, so a different team can pick either one up without reverse-engineering it.
Tell us where your product is, and we will say which engagement fits
Send a short description of the product, who uses it, and what already exists. If the answer is a discovery instead of a build, we will tell you that first — it is cheaper than finding out halfway through.
