The challenge: only the president could quote
Sticker quotes involve a complex mix of paper costs, labor, and processing fees — only the president's experience could produce them. Every quote the president handled took time away from running the company.
- 10 minutes per quote; complex ones took an hour
- Only the president could calculate quotes
- No way to hand the work to employees
How we worked: we brought a working demo to the pitch
We compiled the interviews into a requirements document and used AI to build a working demo in a short time. The president tried it in the sales meeting and signed on the spot. From there we kept a tight build-show-fix cycle and delivered in nine weeks.
See what we built
- Quotation engine (paper, labor, processing, adjustments) with automatic quote PDF generation
- Master-data admin screens — the customer updates unit prices themselves
- Built on AWS with authentication, data storage, and automated tests
- Five post-delivery feedback items fixed in parallel in about two hours
The result: anyone can quote in 2–3 minutes
| Item | Before | After |
|---|---|---|
| Per quote (typical) | 10 min | 2–3 min |
| Per quote (complex) | 1 hour | 10–15 min |
| Who can quote | President only | Any employee |
Development effort came to roughly 60 hours, against an estimated 800 hours had we built it without AI — about 1/13 the effort for a system of the same scale.
*The 800-hour figure is our own estimate for building a system of this scale with conventional methods (not measured in a side-by-side build). The 60 hours is actual hands-on development time; the calendar period was nine weeks.
In the customer's words
Tomokichi Fujimoto, President, J.S. Co., Ltd.
「This alone is a massive win for us.」
これだけでも、めちゃくちゃ儲けもんですよ。
「Even employees who don't know the business can use this. The people on the floor went 'whoa' and 'this is easy.' The team is really happy.」
業務に詳しくない社員でも、これなら使えるな、と。現場の子は『うわ、すげえ』『簡単や』。従業員もかなり喜んでます。
「I still open the browser every morning to check the quotes. It's essential now — it genuinely helps us.」
今も毎朝ブラウザを立ち上げて見積もりを確認してる。これはもう必須やな、ほんますごく役に立ってます。
