FAQ
Answers, before you even ask.
Everything clients usually want to know before starting a project with ZenTech.
A marketing website runs 4-8 weeks, a mobile app or web application 10-20 weeks depending on scope. After discovery you receive a week-by-week roadmap, and we demo working software every sprint - so there are never surprise timelines.
