How it works
- 1
Goals & free estimate
We learn about your business, your customers and what the site needs to achieve, then send a scope and a quote broken down by feature.
- 2
Structure & design
We map the sitemap and user journeys, then design the screens in Figma so you can click through and refine them before any code is written.
- 3
Build in sprints
We build feature by feature with a demo every week. You can review the real site on staging and give feedback at any point.
- 4
Test, content & SEO
We test across devices and browsers and check speed, security and on-page SEO before going live.
- 5
Launch & support
We go live on your domain, submit the sitemap to Google, train your team on the admin panel and support you through the warranty period.
What affects the price
The cost of a website depends on what it actually needs to do, so we quote after a short conversation and break the price down by feature. These are the main things that drive the budget:
Type and size of the site
A few-page company site takes far less work than an online store or web app with accounts, payments and an admin panel.
Design complexity
A clean, structured layout versus a fully bespoke design with custom illustrations and animation.
Features and integrations
Payment gateways, shipping, LINE OA, accounting software or APIs from your existing systems each add development and testing time.
Content and languages
Whether your copy and images are ready or need preparing, and whether the site needs two or more languages.
Ongoing support
Whether you want us to manage hosting, security updates and new features each month. Plans are optional and sized to your needs.

A typical corporate website takes around 3–6 weeks. E-commerce stores and web apps with a substantial back-office usually take around 2–6 months, depending on features, how ready your content is and how quickly feedback comes back. You get a timeline with clear milestones before we start.
You don’t need everything ready. Your goals for the site, a few websites you like, your logo or brand guidelines if you have them, and basic information about your products or services are enough to begin. Let us know about any existing domain or hosting. We can help with structure and content from there.
No one can honestly guarantee a ranking. What we do is get the foundations right: a clear heading structure, meta tags, sitemap, schema, Core Web Vitals performance and mobile-friendliness, so Google can understand and index your site properly. Long-term rankings come from genuinely useful content updated over time.
Yes. We set up a CMS or admin panel so you can edit text, images, products and articles without touching code, and we train your team before handover. For new features later on, see our maintenance and support plans.
We start by reviewing your current site’s code, speed and SEO, then recommend whichever option gives you better value. If we rebuild, we map redirects from every old URL so you keep the rankings you already have. If usability is the main issue, our UX/UI design service may be the right first step.
