FAQ

Frequently asked questions

How long does a website take?+

A landing page usually takes 3–5 days, a business website 1–2 weeks, management software 3–6 weeks. The exact timeline is written in the quote.

How does payment work?+

As agreed in the written quote, before any work starts.

I'm not technical — is that a problem?+

Not at all. Just describe your business; I take care of the technical side and show you how to update content yourself.

Can you help with domain and hosting?+

Yes. I'll recommend and register a domain (.vn, .com) and suitable hosting; you pay those fees directly to the provider.

What if something needs fixing after hand-over?+

I fix bugs after hand-over; the support period is stated in the quote. New features or maintenance are quoted per request.

Do I own the website?+

Yes. You own all the source code, the domain and the data.
