No. 08 — Frequent questions
Frequent questions
How long does a project take?
It depends on the scope. The timeline is written into the proposal before work starts, and you see progress while it is being built.
What do I need to have before we start?
An idea of what you want to achieve. Copy, photos, a domain and the rest get sorted out in the needs assessment.
How much does it cost?
Every business is different, so there is no fixed rate. After the assessment you receive a written proposal.
What access do I get once it is finished?
You get the access you need to use and update your site or system (for example, the admin dashboard) and its manual. How hosting and the domain are handled depends on each project, and it is written into the proposal before work starts.
Do you work with businesses outside Guayaquil?
Yes. The whole process can be done remotely.
What happens after delivery?
I stay available for adjustments and questions. What that follow-up covers is written into the proposal.
