Frequently asked questions
Do you work with small companies or only large ones?
Both. We apply the same quality standards to a professional website as to a financial system; only the scope and budget change.
How much does a project cost?
It depends on the scope. After the free assessment we send a proposal with a fixed quote per phase, so you know exactly what you're paying for.
How long does it take?
A corporate website, 3 to 6 weeks. Custom software or an app, from 6 to 8 weeks for a first version. We always deliver in increments.
Do you sign NDAs?
Yes. We sign an NDA before accessing sensitive information.
What happens after delivery?
A warranty period to fix bugs is included, and we offer optional monthly maintenance plans.
Do you work with clients outside Argentina?
Yes. We work remotely with clients in Latin America, the United States and Europe, in English or Spanish.
