How we work開発プロセス

Six steps, one agreed price.

  1. 01

    Discovery

    A working session on how your business runs and what the website has to do.

  2. 02

    Scope & quote

    A written plan, timeline and one agreed price before any work starts.

  3. 03

    Design

    Page structure and layouts approved before development begins.

  4. 04

    Build

    Progress visible in your client portal throughout, not only at the end.

  5. 05

  6. 06

    Care

    Monthly maintenance, monitoring and support on a Care plan.

Project pricing料金の目安

Starting prices, fixed before we start.

Every project is different. These are starting points for a defined scope. Once we understand your requirements, you receive a detailed proposal and one fixed price before development begins, so there are no surprise invoices halfway through.

Prices exclude consumption tax.

Tsukuba Tech Shared Hosting
共有ホスティング

Hosting that costs less than running your own.

Approved websites and web apps can run on Tsukuba Tech's managed infrastructure instead of a hosting account of your own. Resources are shared across approved projects, so it costs less than a comparable server you rent yourself, and it's run by the team that built your site.

  • Managed server and deployments
  • SSL certificates
  • Automated backups
  • Uptime monitoring
  • Security updates
  • Domain and DNS setup

Approved projects only

Each project is reviewed before it joins shared infrastructure. Approval is based on:

  • Built or reviewed by Tsukuba Tech
  • Standard traffic and storage needs
  • A stack our infrastructure supports
  • Content within our acceptable use policy

Not a fit for shared hosting? We deploy to your own account on AWS, Vercel, a VPS or similar, and you keep full ownership either way.

Pricing is quoted per project once it's approved.
