Frequently Asked Questions

Do you redesign existing websites for San Marino businesses?
Yes — redesigns typically run 60–80% of a new build and include redirect mapping so your existing Google rankings survive the migration.
How long does a website take for a San Marino business?
A custom site takes 4–10 weeks including design rounds and content; e-commerce 8–16 weeks. If an agency promises a custom site in one week, it's a template with your logo on it.
What does ongoing maintenance cost?
$50–$300/month depending on the stack, covering updates, backups, security and small changes. It's optional — you always own the site either way.
Do you build AI automation for San Marino companies?
Yes. AI workflows, voice agents that answer your phones, and chatbots trained on your business — from $1,500. San Marino service businesses use these to answer every lead within minutes, around the clock.
