Questions people ask
- How much work is a typical project?
- These are Kultrix hours, not a market average. An MVP - accounts, payments, content and an admin panel on one platform - is 370-750 hours of work over 7-14 weeks. A full build with the whole module list on mobile and web is 960-2,110 hours over 9-20 weeks. To get a number for your own scope, write to us at kultrix.com/contact.
- How long does it take?
- A proof of concept runs 4-6 weeks, an MVP 7-14 weeks, a full build 9-20 weeks. Kultrix plans a week in focused project hours rather than in calendar hours, because meetings, review and releases are real.
- How accurate is this estimate?
- It is a range, and the range is wide on purpose. The hours come from how Kultrix has actually scoped comparable projects, not from a market average.
- What is not included?
- Ongoing support, infrastructure costs and third-party licences. Design, development, QA and release are inside every Kultrix estimate, and QA is a named 15 percent of the hours.
- Do I have to talk to sales to get the breakdown?
- No. Leave an email and the full module-by-module breakdown arrives by email. If you want it scoped to your product after that, write to us at kultrix.com/contact.
