ERPNext.JP Implementation Cost Guide | The ¥6M Source Buy-Out and the Optional ¥100,000/Month Cloud Plan

How much does it cost for a small to medium-sized manufacturing company to implement an ERP system?

When considering implementing an ERP system, the first obstacle you'll encounter is the "cost barrier".

Major ERP systems cost tens of millions of yen in initial setup fees alone, and even mid-sized ERP systems see costs balloon as the number of users increases through user-based billing. Accounting software lacks the core functions required for manufacturing.

ERPNext.JP's answer is: buy out the entire source package for ¥6 million and own the system as your own asset.

First, a fixed-price ¥500,000 PoC lets you confirm it truly works. Once you're satisfied, we hand over the full source and 9 deliverables for ¥6 million (excl. tax, for your own use). From there, hands-on support (¥15,000/hour) and a maintenance subscription (from ¥50,000/month) support your in-house development — you get a launchpad for building your own AI-powered ERP.

If you'd rather have us handle server setup and operations too, we offer an optional managed cloud plan (¥100,000/month, unlimited users). From order placement to MRP, manufacturing, shipping, invoicing, and monthly closing, everything is handled seamlessly — and the monthly fee stays the same no matter how many users you add.

Cost comparison of major ERP systems (using the optional managed cloud plan)

If you'd rather have us run the servers, the basis for comparison is the optional managed cloud plan (¥100,000/month). Unlike the per-user pricing of other vendors, ERPNext.JP is a flat fee no matter how many people use it. Below are the monthly costs of ERP systems that small and medium-sized manufacturing companies might consider.

	ERPNext.JP (managed cloud, optional)	Odoo Enterprise	Bugyo V ERP	SMILE V
Monthly Fee	100,000 Yen	5,000-8,000 Yen/User	Inquiry Required (Module-based billing)	Modules from 19,360 Yen + DB fee + User charges
If used by 30 people	100,000 yen	150,000 to 240,000 yen	Estimated 200,000 to 400,000 yen	Estimated 100,000 to 200,000 yen
If used by 100 people	100,000 yen	500,000 to 800,000 yen	Estimated 500,000 yen and up	Estimated 300,000 yen and up
Initial Implementation Costs	Included in the implementation support plan	2 million to 10 million yen	Inquiry required	Inquiry required
Account	Unlimited	User-based billing	License-based	User-based billing
Source Code	✅ GPLv3 Released	Partial	❌ Private	❌ Private

Why can we offer the managed cloud plan for 100,000 yen per month?

For those who think, "Isn't that too cheap?", let me explain how it works.

1. Open Source Software (OSS) means zero licensing fees — ERPNext itself is GPLv3. There are no licensing fees like with SAP or Odoo.
2. Sharing Customizations with All Customers — We develop Japanese specifications (consumption tax, forms, manufacturing functions) in-house and provide feedback to all customers. This minimizes individual development costs.
3. Infrastructure Optimization — Optimizing domestic cloud services through economies of scale

It's not a case of "cheap and nasty," but rather the structural advantages of open source.

What is included in the managed cloud plan (¥100,000/month)

The breakdown below is for the optional managed cloud plan, where we handle server setup and operations. If you buy out the source and self-host, you (or a maintenance subscription) take on this operations portion.

Category	Content
Infrastructure	12GB RAM, 6-core CPU, 1TB SSD, domestic data center
Account	Unlimited — No additional fees for all employees, part-timers, and partner companies
Japanese Specifications	Consumption tax (10%/8%), Invoice system, Japanese language, Japanese-style forms
Manufacturing Functions	EDI import, FAX-OCR order processing, MRP, barcode data entry, lot/container management, monthly cost accounting, traceability
Maintenance and Operations	Updates, security patches, server monitoring, and incident response
Backup	Daily automatic backup and disaster recovery system
Support	Q&A support via email and chat
New Features	Free Provision of New Features and Services

Custom development (report modification, screen changes, feature additions, etc.) is charged on an hourly basis (15,000 yen/hour).
We provide an estimate before starting any work, so you can rest assured regarding costs.

Unique in the industry: Improvement requests are directly reflected in the product.

This is surprisingly big.

You can submit improvement requests with screenshots using the 💡 button that is always present on every screen.
The moment you think, "I want to do this here," you can create a ticket with a single click without leaving the screen.

A 3-step process for continuous improvement:

1. Submit a request: Click the 💡 button → Enter the request text. The screen will be automatically captured (no IT literacy required).
2. Internal Approval: Administrators filter requests. Only truly necessary requests reach the vendor.
3. Implementation Support: Automatic notification to the operating company MyHaTch upon approval. Eliminates the possibility of missed requests via verbal or email.

This "improvement cycle" is included in the monthly service.
The dashboard allows you to see at a glance whether an item is "awaiting approval" or "awaiting action," and it also supports automatic detection of error reports (such as 500/417).

For those still undecided about accounting software — A checklist of essential features for manufacturing companies

We sometimes hear people say, "Isn't kintone or accounting software sufficient?"
Please check if the following features are necessary for your business operations.

Required Functions	ERPNext.JP	Odoo Ent.	kintone
Accounting/Expenses	✅	✅	❌ (External Integration)
Sales and Purchasing Management	✅	✅	△ (Custom App)
Human Resources	✅	✅	❌ (External Collaboration)
CRM	✅	✅	△ (Custom App)
BOM / Multi-stage BOM expansion	✅	✅	❌
MRP (required quantity calculation)	✅	✅	❌
Lot Management / Traceability	✅	△	❌
Barcode Data Entry	✅	△	❌
Monthly Cost Accounting	✅	△	❌
Monthly settlement	✅	✅	❌

If you need five or more ✅s, accounting software and kintone cannot structurally cover this.
While kintone is an excellent platform for building applications, it lacks the integrated calculation logic required for ERP systems, such as BOM deployment and inventory projection.

Comparing using TCO (Total Cost of Ownership) over 5 years

There are costs that aren't visible in the monthly fee alone.

	ERPNext.JP	Odoo Ent. (30 employees)	SAP B1	Self-built VPS
Initial (buy-out)	Source package ¥6M (own it)	—	—	0 yen
Running × 60 months	Maintenance ¥50k×60 = ¥3M (self-host) / managed ¥100k×60 = ¥6M	12 million yen	36 million yen	150,000 yen
Initial setup fee	Included above	3 million yen	10 million yen	0 yen
Engineer personnel costs (5 years)	0 yen (inclusive)	0 yen ~	0 yen ~	5 million to 10 million yen
Total	≒¥9M (self-host) / ≒¥12M (managed, optional)	≒15 million yen	≒46 million yen	≒5 to 10 million yen

• The Odoo and SAP figures are estimates based on general market rates found in IT specialized media and implementation case studies.
  
• The total cost of ownership (TCO) for building a VPS yourself is largely comprised of the labor costs of the engineers responsible for its operation.
  
• ERPNext.JP's 5-year total is ~¥9M when you pay the ¥6M source buy-out up front (own it) and self-host with a ¥50,000/month maintenance subscription, or ~¥12M if you add the optional managed cloud plan (¥100,000/month) — matching the ~¥12.2M 5-year TCO in our source-package guide. Either way, the ¥6M up front makes the system your asset, with no per-user billing.

[Flagship] Buy out the source package (¥6 million) and make it your own asset

ERPNext.JP's flagship offering is a source-package buy-out (¥6 million, excl. tax, for your own use). We hand over the full source code and 9 deliverables so the system becomes your company's asset.

Deliverables (excerpt):

• A complete system with working components (environment already configured)
• ERPNext.JP source code
• Development design document
• Development Procedure Manual
• User Operation Manual

It can be deployed on your own servers and freely customized and used for commercial purposes (in your own business).
As a "launchpad" for developing your own AI-powered ERP system — no need to build from scratch. After delivery, hands-on support (¥15,000/hour) and a maintenance subscription (from ¥50,000/month) keep your in-house development going.

You don't jump straight to ¥6 million — start with a ¥500,000 PoC to confirm the fit first. After the buy-out, if you want us to run the servers too, you can switch to the optional managed cloud plan (¥100,000/month). See our source-package guide for details.
