Our Process
First Alignment
We align expectations from day one. We meet to understand your project’s vision, commercial goals, and target audience, setting a clear scope and concrete deliverables.
Discovery Phase
We immerse ourselves in your project's ecosystem. Through in-depth research, we lay a solid foundation for both content strategy and visual design.
Build & Execution
We design the UI/UX in Figma (wireframes, UI kits, and interactive prototypes) and build the final site in Webflow—ensuring a fully responsive, SEO-ready experience optimized across all devices.

Once tested and approved, we launch and hand over the site. We equip your team with the tools to manage it independently—though we also offer dedicated support packages if you prefer ongoing expert help.

Frequently Asked Questions About Webflow & Design
Here are answers to the most common questions about our web design and development services.
Why choose Onsa for a web project?
We are a specialized Webflow Certified Partner agency based in Buenos Aires, Argentina. Our team brings years of experience in UI/UX design and web development. We’ve built websites for leading brands and global companies, guaranteeing clean code, on-time delivery, and transparent, personalized collaboration at every stage.
How much does a Webflow design and development project cost?
Pricing depends on complexity, scope, and required features. We evaluate factors such as the number of static pages, whether Figma designs are ready or built from scratch, custom animations, and no-code integrations (HubSpot, Airtable, Stripe, etc.). We offer fixed-price proposals tailored to each client's needs. Book a 30-minute call, and we’ll prepare a custom quote for you.
How long does it take to develop a website?
An end-to-end UI/UX design and Webflow development project typically takes 6 to 8 weeks. If you already have approved Figma designs and only need Webflow development (or vice versa), the estimated timeline is 3 to 4 weeks. We establish a clear roadmap with weekly deliverables from day one.
Can you help us migrate an existing website to Webflow?
Yes, we specialize in migrating websites from platforms like WordPress, Squarespace, Wix, or Bubble to Webflow. We ensure the original design is preserved (or redesigned if requested), maintain your SEO authority using 301 redirects to protect rankings, and significantly boost page load speed.
What happens after the website is launched?
We aim to build long-term partnerships. Upon delivery, we provide a hands-on training session so your team can edit and upload content with 100% autonomy. If you prefer to delegate maintenance, we offer retainer hours and ongoing support packages to add new features, build extra landing pages, or continuously optimize your site.
Do you train our internal team on how to use Webflow?
Absolutely. At the end of every project, we coordinate a handoff call to walk you through the Webflow dashboard (Editor & CMS) step by step. Additionally, if your team requires advanced training in Figma or web management, we offer dedicated training sessions.
What services do you NOT offer at the agency?
To guarantee top quality, we focus strictly on our core expertise: UI/UX design, Webflow development, and brand identity. We do not offer video editing, complex 3D animations, print editorial design, or packaging.
Where are you located, and which countries do you work with?
Our headquarters are located in Buenos Aires, Argentina. However, we operate 100% remotely and work with clients and brands worldwide—primarily across the United States, Latin America, and Spain.
Are your websites optimized for SEO and mobile devices?
Yes. Every site we build in Webflow includes native technical SEO, responsive design for smartphones and tablets, performance optimization (Core Web Vitals), metadata integration, and canonical tags—fully prepared to rank on Google.
