Pricing & Process
Transparent pricing, from first build to ongoing growth
We work in two ways: one-time projects to build or migrate your site, and monthly retainers to keep it running and growing. The ranges below are a starting guide.
These ranges are a starting point, not a final quote. Your price depends on scope and goals — we give you a firm estimate after a free consultation.

Toppan Global Ventures Partners, Inc Issei Kusano 
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!

FAQ
Pricing questions, answered
Still unsure? Book a free 30-minute consultation and we will scope it with you.
What decides where my project lands in the range?
Scope — number of pages and templates, custom design and animation, CMS complexity, integrations, and whether content and translation are included. After a short consultation we give you a firm, itemized quote.
Do I need a one-time project or a monthly retainer?
A project builds or migrates your site (a fixed deliverable). A retainer keeps it running and growing month to month — maintenance, SEO, content or AI visibility. Many clients start with a project, then move to a retainer after launch. You can do either, or both.
How long does a project take?
A Basic build is typically a few weeks; a full Pro site or migration is usually one to two months. We confirm the timeline in the proposal before any work starts.
How do I pay?
Stripe (card) or bank transfer, against an invoice. Projects are usually split across milestones; retainers are billed monthly.
Are SEO and AI optimization one-time or ongoing?
Ongoing. SEO and AIO compound over months — they live in the Growth retainer, not the one-time project tiers.
Do you work in both English and Japanese?
Yes. We are a bilingual team and deliver projects, support and content in EN and JA — including localization for entering Japan or expanding abroad.
