Frequently Asked Questions

Straight answers about timelines, technology and how projects run.

How much does a project cost?

It depends on scope. A simple website, a website with a client portal, and a custom CRM or SaaS platform are very different projects. Describe what you need in the quote form: you get an instant preliminary estimate, and a confirmed proposal within one business day.

How long does it take to build?

A simple website is usually live in 1 to 2 weeks. A website with a client portal typically takes 3 to 6 weeks. Larger CRMs, SaaS platforms and mobile apps are delivered in weekly increments so you see progress from the first week.

What technologies do you use?

Most projects are built with Next.js, React, TypeScript, Tailwind CSS, PostgreSQL with Prisma, and Supabase, deployed on Vercel. Mobile apps use Expo / React Native. AI features use the Claude API and other model providers. Payments are handled with Stripe, Mercado Pago or PayPal depending on your market.

Do you work with clients outside Brazil and the United States?

Yes. Vieira Ruiz Studio works remotely with clients worldwide, in English and Portuguese. Communication happens over WhatsApp, email and video calls, and every active client gets a private portal to follow progress and payments.

How do payments work?

Fixed-price projects are usually split into weekly or milestone payments that you can track in your client portal. Hourly work is invoiced with a detailed breakdown. Maintenance can be arranged as a monthly plan.

Can you add AI to my existing business software?

Yes. Common requests are AI assistants that answer questions from your own data, document and email parsing, automatic report generation, lead qualification and workflow automation. AI features are connected to your real workflows, not added as a gimmick.

Will I own the code and the website?

Yes. You own the code, the domain, the hosting accounts and the data. Everything is delivered in your own accounts so you are never locked in.
