CUSTOM DEVELOPMENT
Systems that would normally cost hundreds of millions — built within reach.
Order-to-invoice automation and other backbone systems, custom-built around your operations. Your current software stays. The CEO personally leads from requirements through operations.
* We don't start with a build. First, Tech Advisory (from ¥100,000/mo) settles the requirements.
HOW IT WORKS
We don't start with a build. We start with Tech Advisory.
Advisory settles the requirements and confirms whether it's worth building — so you never end up with something you can't use.
Start with Tech Advisory
From ¥100,000/mo
We review your operations together and decide what — and how far — to automate with AI.
Try it, then judge
1-month trial first
Whether to build at all, whether SaaS (Totsugo.com) is enough, or whether custom is right. You can also decide to stop here.
Build once it's settled
Development from ¥30M
Development starts only once requirements and ROI are clear.
WHY THIS PRICE IS POSSIBLE
US-style development — Leach keeps the IP, you hold the license
- 1
Leach retains the intellectual property of the system; you receive the license and monthly operations support (a standard arrangement in the US)
- 2
We build on shared foundations and AI instead of starting from zero every time
- 3
That is how systems large enterprises spend hundreds of millions on become reachable
Examples of work you can hand over entirely
Full automation from order intake → verification → invoicing
Integration layers that coexist with freee, Excel, and your ERP
Reading and transcribing forms arriving by PDF, fax, and email
Semi-automated monthly closing, matching, and discrepancy checks
PRICING
Development from ¥30M (custom quote) + operations from a few ¥100Ks/mo
Systems that would normally cost hundreds of millions can be quoted at this level because of the US-style model (Leach keeps the IP; you hold the license). Monthly operations covers maintenance, improvement, and hands-on support. Requirements are settled through the free diagnosis and Tech Advisory first, and the free/paid boundary is always stated in writing with the quote.
We don't stop at delivery
Systems built for you are later released as SaaS so companies with the same pain can use them — Totsugo.com itself was born this way. Bringing systems to life that were too expensive to exist: that is Leach's mission.
FAQ
Q. Does it cost ¥30M right away?＋
No. First, Tech Advisory (from ¥100,000/mo) settles the requirements, and development starts only once it's clear a build is worth it. You always confirm the ROI before any development.
Q. If Leach keeps the IP, is that bad for us?＋
Your business data and confidential information remain yours (NDA available). What Leach holds is the copyright to the program — and that is exactly what we discount from the development cost. Your license never lapses while the contract stands.
Q. How long does development take?＋
It depends on scope, but after requirements we show you small working pieces every few weeks. We never go dark until a big-bang delivery.
Q. What if requirements change midway?＋
Continuous improvement is part of the monthly operations support. Business changes — we design assuming it will.
