Process
Simple steps, a clear path
We follow a process built around a few core steps.
-
Research & Planning
We start by understanding your business and goals. The questions vary by the purpose of the site — for a marketing site we learn about your products, services, customers and competitors — then plan the structure, core message and functionality.
-
Design Optional
We create a wireframe outlining the core sections and CTAs. Once the structure is finalized, we develop a detailed design using colours, shapes and graphics so the site reflects your brand.
-
Development
We build Webflow pages using our framework, which leverages components and variables for easy management and scalability.
-
Tests & fixes
We test the whole site across devices and browsers, then give your team a staging site to review. We collect all feedback and implement the necessary fixes.
-
Publish & Support Optional
Once the site is live, we train your team to manage and grow it. Optionally, we offer a maintenance agreement for ongoing support.

I feel grateful that they do not only flexibly help to build the website and do fixes, but also understand about our business model and marketing. I would say that Supasaito is not a typical "development agency", but a technology partner working together to grow our business. Thank you!
