SERVICES
Services & Pricing
For small and midsize companies in Kumamoto: from the AIX Advisor to development and websites. Transparent, quasi-delegation-based pricing, with real cases below.
Concept
Think of us as your "tech department," not an "outsourcer." A dedicated engineer who gets on the ground and accelerates your business.
Nexa Engineering is not a dev shop that builds to spec and walks away. Drawing on 15 years of "floor sense" from the factory, we embed deeply in your workflow. We think with you about "what the real problem is," and keep implementing and improving the small mechanisms that solve it by the shortest path.
Price Policy
"No opaque estimates." We make "what cost what" fully transparent. Instead of a lump-sum quote padded with risk buffers, we offer a quasi-delegation–based model grounded in actual work and technical value.
Three entrances
Three ways in, depending on the shape of your challenge.

AIX Advisor
A monthly advisor embedded in your management — from AI sparring to hands-on implementation of small mechanisms. No minimum term; everything we build, and its data, is handed over on cancellation.
Advisory
¥50,000/ mo
Monthly session (60–90 min)
Advice & sparring
Chat support plus a monthly session. AI adoption sparring, tool selection, and internal rollout advice to support decisions.
- Recommended
Companion Advisor
¥150,000/ mo
Biweekly–weekly sessions
Advise & build
Sessions and support with a build slot. We implement the small mechanisms decided in each session and see them through to adoption.
Transformation Partner
¥300,000/ mo
Weekly sessions
Transform & prioritize
Weekly decision-making sessions, a priority build slot, and priority response when urgent. For entrusting your tech function entirely.
* Prices exclude tax. The advisor build slot covers small improvements decided in sessions; larger development runs under quasi-delegation (rates below).
Hourly rates
Three tiers by what you need done (excl. tax, per hour). Every estimate and invoice shows which rate applied, and for how many hours.
- Fix & maintain
Support
¥5,000/ hr
"A small fix to what you built for us."
Minor fixes, troubleshooting, and settings changes for systems we built (or took over). E.g. copy or field changes, restoring something that stopped working, settings updates when staff change.
For ongoing monthly support and improvement, the AIX Advisor plan is better value.
- Build & automate
Development & automation
¥10,000/ hr
"Get rid of this manual work." "We need a system that fits how we operate."
Apps, automation, and dashboards that make daily work easier — most requests land here. E.g. LINE/Slack reception and notification bots, automating Excel re-entry and tallying, an at-a-glance sales and inventory dashboard, moving in-house systems to the cloud.
- Push the frontier
Advanced AI development
¥15,000/ hr
"Build a system where AI does the work itself."
R&D with the latest AI — challenges without textbook answers yet. E.g. an AI assistant trained on your documents and data, mechanisms where AI operates your internal systems directly, demand and sales forecasting models.
* Excl. tax. You pay only rate × actual hours. AI-driven development compresses the work itself, so even at a higher hourly rate, the total usually comes in below conventional outsourcing.
Sales systemization (end-to-end)
We build a "sales mechanism that sells," starting from a free diagnosis. See sales systemization for details.
| Stage | Price (excl. tax) |
|---|---|
| Diagnosis (half-day interview) | Free |
| 2-week prototype sprint | ¥500,000 (fixed) |
| Full implementation (sales, CRM & marketing, end to end) | Individual quote |
| Ongoing operation | Continues as AIX Advisor (above) |
Seminars & training
Practical, hands-on topics: getting started with AI, AI-driven management, and DX on the shop floor.
| Offering | Price (excl. tax) |
|---|---|
| Lecture / seminar (60–90 min) | from ¥50,000 |
| Half-day AI workshop (up to ~20 people) | from ¥150,000 |
| In-house AI training (multi-session series) | Let's talk |
- Lectures include material preparation. Travel expenses billed at cost.
Model Case
A real-estate sales company — intensive build, then advisory
A case where intensive development ran for the first three months, and after the system was in place, they moved to the AIX Advisor (Advisory tier) to continue improvement.
| Phase | Period | Example work | Monthly cost (approx.) |
|---|---|---|---|
| Onboarding | Month 1 | Foundation build & chatbot rollout | approx. ¥150,000 |
| Expansion | Month 2 | Sales-support AI & management dashboard | approx. ¥300,000 |
| Adoption | Month 3 | Feature expansion & deeper automation | approx. ¥200,000 |
| Operation | Month 4+ | Move to AIX Advisor (advice, upkeep, small improvements) | approx. ¥50,000 |
A software development company — year-round support that flexes with demand
A case where we support development throughout the year as part of their tech team. Because the contract is quasi-delegation, the workload scales up in busy periods and narrows to maintenance in quiet ones — monthly cost moves between roughly ¥100,000 and ¥700,000 with demand.
| Period | Example work | Monthly cost (approx.) |
|---|---|---|
| Peak development | Design & build of major features | approx. ¥500,000–700,000 |
| Normal months | Feature additions, improvements, reviews | approx. ¥200,000–400,000 |
| Quiet months | Maintenance, small fixes, technical advice | approx. ¥100,000 |
- Both are models based on actual billing. We adjust flexibly to your budget.
