FAQ

Do I need to know about technology?

No. Knowing your business is enough: tell us in your own words and we take care of the technical side.

Can I start with just one part?

Yes. Many projects start with the website or a specific automation, and the rest is added when it makes sense.

How long does a project take?

It depends on the scope. Before starting you get a plan with fixed timelines and price.

Is AI useful for a small business?

Yes, when applied to a specific task: answering enquiries, classifying contacts, generating documents or connecting tools.

Is there a minimum term?

No. Monthly management is billed month by month and can be started, paused and resumed.

Is there support after launch?

Yes. We stay available to adjust and extend what we built as it gets real use.
