Build & Software
Web Application Development in Singapore
We build web applications that run the parts of your business a website can't, from customer portals and booking systems to internal dashboards. Senior engineers architect for security, speed and growth, so the app still performs when your users and data multiply. You get one accountable partner from spec through to support.
💡 Custom work may be up to 50% EDG-supported, subject to Enterprise Singapore approval — check your eligibility.
For businesses outgrowing spreadsheets, manual processes or off-the-shelf tools that almost fit but never quite. Ideal if you need a secure portal, booking or member system tailored to how you actually operate.
Everything you get, handled by one team.
Custom web applications
Bespoke browser-based tools built around your exact workflow, not a rigid template.
Customer & partner portals
Secure logins where clients or partners self-serve, upload, track and transact.
Booking & member systems
Scheduling, membership, payments and reminders that cut admin and no-shows.
Dashboards & reporting
Live views that pull data from your systems into decisions you can act on.
Authentication & roles
Role-based access, audit trails and PDPA-conscious handling of personal data.
API & system integration
Connect the app to your existing tools so data flows in one place.
Outcomes, not just deliverables.
- Hours of manual admin removed as workflows move from spreadsheets into one system
- A tool shaped exactly to your process instead of forcing your team into someone else's
- Secure, role-based access with an audit trail that supports PDPA obligations
- An architecture built to scale, so growth doesn't force a costly rebuild
The GDI Build Loop.
Discover
A free scoping call and short discovery to pin down the goal, the scope and how we'll measure success.
Prototype
We shape the solution and put a working prototype or clear plan in front of you — not a slide deck.
Build
Senior, AI-native engineers build fast, with working progress you review as we go.
Launch
We deploy, test and hand over — documented, secure, and fully owned by you.
Support
Ongoing support, iteration and optimisation as your needs grow.
Engagement & pricing
Fixed-scope projects or ongoing retainers — your choice. Retainers cover scheduled maintenance and changes, not round-the-clock monitoring. We give a clear fixed quote after a free scoping call, and you own everything we build. Eligible custom work may be up to 50% EDG-supported, subject to Enterprise Singapore approval. PSG funds only listed vendors' pre-approved products, and GDI is not listed.

How is a web app different from a website?
A website presents information; a web application does work, such as taking bookings, managing members or crunching data behind a login. If your users need to log in and get something done, you likely need an application rather than a brochure site.
Can you show that you build real software, not just sites?
Yes. We build and run our own products, including PropAce for property intelligence and TenderSG for government tender intelligence. They are the same class of secure, data-heavy web applications we build for clients.
How much does a custom web app cost?
It varies widely with scope, integrations and user roles. We break the build into phases and give a fixed quote after a free scoping call, so you can start with a focused first release rather than commit to everything at once.
Is custom software grant-eligible in Singapore?
Custom digital solutions may be supported under the Enterprise Development Grant (EDG) where they drive real productivity or transformation, subject to Enterprise Singapore's criteria. We scope the project so it aligns with how you plan to fund it.
Store Migration
Move off the marketplaces onto a store you own — products, variants, images and all.
