Working Example

The calculator your customers keep asking for

It’s the feature Malaysian businesses request most once their website is live: a calculator, quote builder or interactive section that answers “how much?” on the spot — and hands you the lead while the visitor is still interested. No contact form, no waiting. The working sample below is built for a fictional printing & signage shop — yours would carry your brand, your products, your prices.

  • 20–40% of users finish a good calculator — versus 2–5% on a plain contact form. An instant answer beats “email us for a quote”.
  • Every visitor who calculates is pre-qualified. They’ve already seen your price range fits before they ever talk to you.
  • Leads land straight in WhatsApp. Quote, name and details arrive as a message to your team — the channel your customers already use.
  • Small job, big return. Fits your existing website, fixed price, typically live in about two weeks.
Not sure what to build? Tell us your customers’ most-asked question — that’s usually the calculator.

FAQ

Questions Malaysian businesses ask us

How much does an app cost in Malaysia?

Most projects land between RM30,000 and RM150,000 depending on scope. Our MVP package starts from RM29,000 and includes a 5-day prototype so you see exactly what you’re paying for before we build — the price you see is the price you pay.

How fast can we launch?

Working prototype in 5 business days, MVP in 4–6 weeks for most projects. That’s roughly half the industry standard, thanks to AI-assisted discovery, design sprints and reusable in-house components from our own products.

I only have an idea, not a spec. Where do we start?

That’s exactly where most of our projects start. Book a free 30-minute scoping call — we’ll help you shape the idea, then deliver a clickable prototype in 5 days so you can see and touch it before committing to the build.

Do you also build iOS and Android apps?

Yes — but our default is to launch as a web app / PWA that works on every device, then package the same code for the App Store & Play Store when you need store presence. That keeps your first version fast and affordable — no expensive double builds.

What does “AI built in” actually mean?

Your app ships with working AI features — chatbots, WhatsApp agents, document automation, recommendation engines — integrated as native features, hosted on our infrastructure with bundled LLM tokens. Not a demo, not an afterthought: working AI on launch day.

Do you handle hosting, maintenance and support?

Yes, end to end. We host what we build on our own VPS/cloud/GPU infrastructure, provide AI-powered monitoring and updates, and give you 24/7 Malaysian support. One partner, no vendor juggling.
