System development

We split requirements into small slices and ship a working minimum system first, absorbing real-world drift as we improve.

After listening carefully to the work and on-site constraints, we design the configuration that best fits the goal.

When existing cloud services or off-the-shelf software meet the requirements, we build the workflow around them.

When existing products don't cut it, we build a system tailored to the work.

We also weigh hybrid setups combining existing services with custom development, and choose between cloud, on-prem or hybrid in light of operations, cost and security.

Rather than starting from a specific product or configuration, we propose the form with the least friction — choosing among build / use / combine.

A flexible approach (supplementary)

We pick "build / use / combine" to match the site and put together a configuration without friction.

  • We use what existing tools already cover and only build what they don't.
  • Cloud / on-prem follows the operating conditions.
  • The configuration follows the work, not a fixed product.

How we run it

  1. Requirements organization and non-functional review
  2. UX / UI and data design, plus prototyping
  3. Implementation, testing and release planning
  4. Operational workflow and an improvement plan

Outcomes we aim for

Longevity first: managing operating cost and the pace of improvement.

Easy to operate

Procedures, permissions and logging are organized so the system is easy to hand over.

Improvement cycle

Designing a post-release improvement roadmap and a tight update cadence.

The goal isn't just delivery — it's an arrangement the business actually settles into.

We're based in Minato, Tokyo. Depending on the work, we combine on-site meetings and web conferencing (both in Japanese).

Frequently asked questions

Common questions about this service. See the site-wide FAQ for more.

What scale of system development do you handle?

We handle small to mid-scale business systems that can be developed partially and in stages. We split requirements into small slices, build a working minimum system first, then improve it. We do not handle large-scale contract development, systems that require 24/7 monitoring, or projects premised on headcount or man-hours.

Can this be combined with existing SaaS or off-the-shelf software?

Yes. When existing cloud services or off-the-shelf software can meet the requirements, we design the workflow around them and build only what's missing. We also consider hybrid setups that combine existing services with custom development, and the choice between cloud and on-premises, from an operations and cost perspective.

What's the cost range for business system development?

For partial or staged business system development, the reference price is from tens of thousands to several hundred thousand yen. This varies with the scope (department, process, screen, report, permissions), integration with existing systems or SaaS, and non-functional requirements such as security and audit logs, so we quote each project individually after a free consultation.
