Frequently Asked Questions
Everything you need to know before choosing a software outsourcing partner for your business.
What does a custom software development company do?
A custom software development company designs and builds software to a client’s specific requirements rather than selling a packaged product. Tech JDI, part of Singapore-based JDI Group, builds proofs of concept, prototypes, MVPs, pilot systems and full production platforms, and also modernises and extends software companies already run.
How much does custom software development cost?
Cost depends on scope, and Tech JDI offers three commercial models so the pricing matches how well-defined the work is: fixed price for a defined scope, headcount for ongoing capacity, and pay-as-you-go for intermittent work. The discovery call is free and scoping happens before any commitment.
Should we build in-house or outsource software development?
In-house makes sense when software is your core product and you can hire and retain engineers. Outsourcing makes sense when you need capability faster than you can hire it. Tech JDI offers a third path: build with us, then take the team in-house through a structured Tech Scale-Up transition.
What is Tech Scale-Up?
Tech Scale-Up builds your own engineering capability and transfers ownership to you. It covers tech team formation, transition planning, team preparation, knowledge transfer and post-transfer support. Engineers are augmented into your development team and familiarised with your system progressively rather than handed over in a single event.
Is offshore software development in Vietnam secure?
It depends on the provider’s controls. Tech JDI’s Vietnam entity holds ISO/IEC 27001:2022 certification from BSI under certificate IS 827563, with a scope that explicitly covers software outsourcing and offshore development centre operations. Access control, audit trails and data handling are designed into projects rather than added afterwards.
Can you work with our existing codebase?
Yes. System enhancement and refactoring is one of our three core delivery services — improving code quality, performance and maintainability without disrupting existing operations — alongside feature expansion and module builds on live systems.
Where does your development team sit?
Tech JDI contracts through a Singapore entity and delivers from Vietnam, with offices in Ho Chi Minh City and Da Nang, plus a presence in Australia. Working hours overlap with Asia Pacific and the morning in Europe, and teams flex to cover other time zones.
Do you build in specific industries?
Tech JDI maintains published practices in fintech, healthtech, deep tech and Web3, and has delivered across e-commerce, IoT, education, cybersecurity, HR tech, proptech, logistics and AI.
What happens when the project ends?
Either Tech JDI continues to iterate and scale with you, or you take it in-house through Tech Scale-Up, which includes knowledge transfer, documentation and post-transfer support.
