Can you really implement your system using the free ERPNext? — An honest evaluation using a 45-item rating system.

I'll give you an honest answer to the question, "Can't you go for free?"

"ERPNext" is a widely used open-source ERP worldwide. In Japan, too, there is a growing demand for a free ERP system that companies would like to try.

However, there is a question that anyone proceeding with the consideration will inevitably encounter.

"I understand it's free to run. But can we really proceed with implementation?"

In this article, we will visualize its scope using a 45-item rating chart and, along with the recurring failure patterns in the age of AI development, we will be as honest as possible.

Conclusion: Free is sufficient if you just want it to work. Implementing it properly requires a different approach.

• Just try it: Free and takes only 5 minutes.
• For full-scale operation: An extension group tailored to Japanese practical use is required (see the score table below).
• Is it faster to create it ourselves with AI?: You can get to a prototype. But "something that works" and "something that runs in actual business" are two different things.

For those who want to get started first

A hands-on guide to get you up and running in 5 minutes is available in a separate article. It covers everything from installing Docker Desktop to using the Japanese UI, written in a way that even those unfamiliar with IT can easily follow.

This article will address what comes next—Can we actually proceed to implementation after getting it working?

[Main Topic 1] How far does the free service extend? — A 45-item rating chart

ERPNext is free and takes only 5 minutes to get started. However, when you try to implement it in your company's operations, a gap becomes apparent between the original standard and Japanese practical applications.

We have compiled the extensions that we have actually implemented as ERPNext.JP into a 45-item rating chart, comparing them to the standard features of the original ERPNext.● However, "it can be handled with the original standard,"★ "Enhancements added with ERPNext.JP", These features are designed for use with tablets/smartphones.

These aren't just "nice-to-have" features; they are essential for fully integrating your business processes into ERPNext. If you stick to the standard configuration, you'll inevitably hear complaints from the field like, "We could do this with the old system."

[Main Topic 2] An honest answer to the question, "Wouldn't it be faster to create it with AI?"

In recent years, the accuracy of code generation AI has reached a level that is sufficient for practical use, and it is now possible to carry out individual extensions of ERP systems using AI pair programming. That is a fact.

However, in our experience consulting with clients, we have observed certain patterns of failure that we see repeatedly.

Pattern 1: Prototype Scam

We had AI write the code, and we were able to create something that "works" in one to two months. The internal demo also passed. However, the moment it's put into production, exception handling, permission boundaries, audit logs, and support for multiple companies all fall apart. There's a much deeper gap than you might imagine between something "being in motion" and "actually running smoothly in practice."

Pattern 2: The accumulation of individual extensions leads to overall collapse

Each time a request comes in, we expand it locally. After six months, the rules differ from screen to screen, and no one can grasp the overall consistency anymore. Making changes will cause other parts to break, and the pace of repairs will slow down considerably. The value of an ERP system is determined not by the number of screens, but by its consistency.

Pattern 3: The person in charge leaves, creating a black box.

Only one person in the company knows the details. The moment that person is transferred or leaves the company, the individual extensions written by the AI ​​become a black box. We receive inquiries several times a year from people who say they can't maintain their existing code and end up having to rewrite it from scratch.

Requires a deeper level of design than simply creating "moving objects."

ERPNext is powerful. However, to fully implement business operations, it requires a deeper level of design than just a "working" system—exception handling, permission boundaries, audit trails, and methods for maintaining consistency.

One of the launching pads for this is ERPNext.JP, which is operated by us at MY HATCH.

If you're at the stage where you want to specifically consider whether it's suitable for your company's operations or where to start, please feel free to contact us. github@erpnext.jp

The Value of MY HATCH — A Partner for "Understanding Implementation" in the AI ​​Era

MY HATCH doesn't just deliver the source code and consider the job done. Our core value lies in ensuring that the solution is fully implemented in your operations. Specifically, we support you at a layer above the source code.

• Incorporating on-site innovations outside of the system
• Defining the boundaries of integration with existing tools such as Excel.
• Defining requirements for the factory floor (who inputs what and when)
• Switching between old and new systems requires meticulousness and experience.
• Support during the initial period of confusion after the transition
• Managing requests for repairs (deciding whether to proceed, not proceed, or postpone).

ERPNext is the "ultimate, most flexible ERP." That's why, to fully implement that freedom, you need a supportive partner. For customers who say, "We want to do it ourselves, but we're unsure how far we can go," our role is to get them right up to the final meter.

In recent years, it has become possible for anyone to write custom extensions using AI. However, the danger of releasing them into production without understanding them has definitely increased. We want to be a company that deeply understands Frappe/ERPNext and takes care of everything from design and authorization to audit trails and maintenance. With that in mind, we have released this starter.
