As the Owner and Director of ISMS Global, Australia, I understand perfectly how challenging it is to find a support team of skilled and professional developers to help grow a system. A few years ago, I found STS Software, led by Mr. Thanh Pham (CEO), and I have never looked back. STS has single-handedly taken ISMS camp management software from a concept on a napkin to an international product used by major companies around the world. If you are looking for a trusted partner to help you, then you should be talking to Thanh Pham.

Mr. Paul Upson

Director of ISMS Global, Australia

I have not had an issue with any of STS Software's team. I have had a couple of project managers already, and various dev. teams. The team are so knowledgeable, I feel very safe and secure these days as I spec. in my next bit of work.

Narith Sen

Vendor Manager of DMI Global, USA

I have worked with Thanh (Bruce) Pham, CEO of STS Software on several projects and I admire his professionalism and his dedication to delivering high-quality work. He is responsive when answering emails and calls, as well as making sure that work always gets done on time. I am glad to be working with him and hope to continue working with him.

Mr. RJ Macasaet

Head of Partnership – DMI Global

I would recommend companies to work with STS Software for their Software development or service needs. The project team is very responsible for their work and would recommend solutions in the interest of the client. The team also responds very quickly to requests, bugs, and questions. One exceptional quality of STS Software was their patience for clients. There were several times when we were slow to respond or test our apps but the project team was still very accommodating towards us.

Jeremy Heng

FAQs

How much does custom software development cost?

Custom software development costs can feel like a mystery, but they’re not random. They come straight from what your project needs—like its size, features, and where you build it.

In 2025, expect to pay anywhere from $20,000 for a basic app to over $500,000 for a big enterprise system. This guide breaks it down into eight key factors with real estimates. Use it to get a clear picture and plan your budget.

How long does it typically take to complete a software project?

Project timelines depend heavily on the project’s scale and complexity. Simple projects (e.g., MVPs or basic web apps) can take 2–4 months. Medium-complexity projects generally require 4–7 months, and large enterprise-level solutions may take 8 months or longer. We utilize Agile methodologies to ensure timely delivery and consistent progress updates.
