FAQ
Questions people ask before starting.
How much does a website or system cost?
It depends on scope. A company website is a very different project from a multi-branch ERP. After a short free consultation we send a written scope and a quote, so you know the cost before any work starts.
How long does a project take?
Websites typically take 2 to 4 weeks. Web and mobile apps usually take 2 to 4 months for a first version. Larger systems are delivered in stages so you start using parts of them early.
Do you work with businesses outside Indonesia?
Yes. We work remotely with clients in Indonesia, Australia and other countries, in English or Bahasa Indonesia.
What happens after launch?
We stay on for maintenance, hosting, fixes and new features, or hand everything to your own team with documentation. Your choice.
Can you improve a system we already have?
Yes. We can audit, fix, extend or integrate existing websites and software, even if another developer built them.
