Process
What a project with Web-Duarte looks like
A transparent process: you always know where your project stands and what it costs.
- Step 1
First conversation
A free conversation, by video or at your premises, to understand your business, your goals and your constraints. You leave with an honest opinion, even if the agency is not the right choice for you.
- Step 2
Scoping & proposal
Scope, timeline and budget are set out in a written proposal you can actually read. You know what you’re buying before you sign: what is quoted is what is delivered, no surprises along the way.
- Step 3
Design & build
Mockups first, then short development iterations with regular demos on a staging environment. You watch the project take shape and can adjust early, while changes are still cheap.
- Step 4
Testing & launch
Testing, performance, security, SEO, hosting and domain name: the project is delivered ready to use. You leave with the credentials, the code, the documentation and, if needed, a handover session.
- Step 5
Support & new features
After launch, the agency stays available: maintenance, fixes, new features. You own your code and your data.
