How much does custom software development cost?

Cost depends on scope, integrations, and complexity rather than a fixed price list. We scope the work together first, then give you a clear estimate, and we often start with a smaller phase so you can see value before committing to the full build.

How long does it take to build?

A focused first version typically takes a few weeks to a few months, while larger platforms run longer. Because we deliver in short iterations, you see working software early instead of waiting until the very end.

Do I own the code and the intellectual property?

Yes. You own the source code, the documentation, and the credentials to it once the work is delivered. There is no lock-in, and a future team can pick it up and extend it.

What happens after launch for maintenance and support?

We treat maintenance and support as part of the product, not an afterthought. We can monitor, fix, and keep evolving the system, and because the code is documented and handed over, you are never dependent on a black box.

Can you integrate with our existing systems?

Yes. A large part of what we do is connecting tools you already run such as ERP, accounting, payments, logistics, and CRM through APIs and integrations, so data flows once instead of being re-keyed by hand.

Custom Software Development in Jakarta — Web, Mobile & Systems Built Around Your Business

Off-the-shelf software is built for the average company. Yours is not average. The workflows that make you efficient, the rules that keep you compliant, the edge cases your team handles every day — generic tools rarely fit them, so people end up bending the business to match the software instead of the other way around.

Custom software development reverses that. We build systems around how your business actually works, so the software removes friction instead of adding it. That is the core of what RAPTEK does: web applications, mobile apps, APIs, and integrations, delivered from a first working prototype all the way to a production system your team can depend on.

What we build

Web applications. Internal tools, customer portals, dashboards, and full platforms — built to be fast, secure, and maintainable, not just demo-ready.
Mobile apps. Android and iOS applications that feel native, work offline where they need to, and stay in step with your web systems.
APIs & systems integration. The connective tissue between the tools you already run — ERP, accounting, payments, logistics, CRM — so data flows once instead of being re-keyed by hand.
Modernization. Replacing brittle spreadsheets and aging legacy systems with software that is safe to change and ready to grow.

Problems we solve

Most teams come to us with one of a few familiar pains: a manual process that no longer scales, data trapped in disconnected tools, a legacy system nobody dares to touch, or a product idea that needs to reach the market before a competitor’s does. The common thread is that the software is now the bottleneck — and the right build turns it back into an advantage.

How we work

We deliver in short, visible iterations rather than disappearing for months and hoping the result matches the brief. You see working software early and often, which means direction is corrected while it is still cheap to correct. Whether a project suits a predictable fixed scope or a more adaptive, evolving one is a decision we make together and openly — we wrote a full guide to that trade-off in Waterfall, Agile, and Scrum, explained.

A typical engagement moves through five stages:

Discovery — understand the business, the users, and what success actually means.
Design — shape the flows, the data model, and the architecture before writing production code.
Build — develop in iterations, with working software you can review at each step.
Launch — test, harden, and deploy with care.
Support — maintain, monitor, and evolve the system as your needs change.

Our technical approach

We choose technology to fit the problem, not the other way around. Architecture is kept as simple as the requirements allow and no simpler; code is tested, documented, and written to be handed over — never a black box that only its author understands.

One early decision shapes cost, speed, and control for years: where the software runs. Cloud, on-premise, or a hybrid of both each has a place, and the right answer depends on your workload, compliance needs, and time horizon. We walk through that choice in detail in Cloud vs on-premise infrastructure.

What you get

Every engagement ships more than a running application. You get clean, documented code and the credentials to it, a system designed so a future team can extend it, and a direct line to the people who built it. We treat maintenance and support as part of the product, not an afterthought — software is a living system, and ours is built to keep evolving with your business.

Why RAPTEK

We are a Jakarta-based technology company with senior engineers and over fifteen years of combined experience building real systems for real businesses across Indonesia. We are small enough that you work directly with the people writing your code, and experienced enough to know which shortcuts are safe and which ones cost you later. We build software we would be willing to maintain ourselves — because often, we do.

Start the conversation

If you have a process that no longer scales, systems that do not talk to each other, or an idea you need built well, we would like to hear about it. The first conversation is a free consultation — no obligation, just a clear, honest view of what it would take to build it right.
