ERPNext.JP Implementation Cost Guide | Breakdown of the ¥100,000 Monthly Fee

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 offers the answer: "¥100,000 per month, unlimited users."

From order placement to MRP (Material Requirements Planning), manufacturing, shipping, invoicing, and monthly closing, everything is handled seamlessly. It supports purchasing, HR, and CRM. And best of all, the monthly fee remains the same regardless of the number of users.

Why can we offer this 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.

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
Monthly payment × 60 months	6 million yen	12 million yen	36 million yen	150,000 yen
Initial setup fee	Included in the setup support plan	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	≒6 million yen	≒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.

We also offer a "Self-Managed Operation Plan".

We offer a self-management plan (price negotiable) for IT companies and companies with engineering teams.

Deliverables:

• 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.
As a "launching pad" for developing your own AI-powered ERP system — no need to build from scratch.

You can start with our "Cloud plan at ¥100,000 per month" and then transition to in-house operation in the future.
