Should You Use a Standard System or Build a Custom Solution?

Thank you for your interest and continued support.
This is Takahashi from the Marketing Plan Research Laboratory.

When considering the implementation of a business system, company presidents typically face two main options:
Should you purchase an off-the-shelf package?
Or should you develop a custom solution for your company?

While there's no single correct answer to this question, the decision criteria are surprisingly straightforward. You can approach this choice from the perspective of "where do you shift the costs?"

Purchasing a package solution essentially means adapting your business operations and workflows to fit the database structure.

Building a custom system means adapting the database to fit your business operations.

With a package solution, the software is cheaper but work increases, while custom development results in more expensive software but easier work processes. In other words, "packages shift costs to employees" while "custom development shifts costs to the software side." The core of the decision lies in determining which type of cost is more acceptable for your organization.

Package solutions are most suitable for accounting software and standardized attendance management and payroll systems. These areas operate under rules (laws) that are virtually universal not just across industries but nationwide, and most companies can define these areas as having no unique company-specific requirements. Updates for legal compliance are also very cost-effective, so it's reasonable to ask your accounting and administrative staff to handle these systems.

Additionally, B2C industries tend to be highly competitive, which has led to an abundance of available package software options.

On the other hand, what systems should be built with custom development? While there are no clear standard practices here, custom development is more suitable when the workflow itself represents your company's core strength.

Production processes tailored to unique processing technologies and precise formulations, customer service and order processing that leverages proprietary know-how to achieve high precision, quality, and satisfaction, or successful customer retention methods - these elements that constitute "the source of your company's profitability" should be properly systematized and implemented with reproducibility as the goal. If you adapt these areas to fit package software, you risk moving closer to the operational quality of competitors using the same software.

Of course, the primary source of strength lies in people - individual employees - but business systems are a major factor in shaping company culture. Software inevitably influences people to some degree. If the core of your "source of strength" lies in how work is performed, then custom development to protect that approach represents a sound investment.

Regardless of business operations or "sources of strength," when prioritizing cost reduction for software users, custom development can provide significant value. When daily work is busy and changing operational methods (adapting to package software) would likely cause enormous effort and confusion, you should straightforwardly begin developing a custom system. The cost-effectiveness increases with the number of users. In this case, let the system developers do the hard work instead of your employees.

To summarize the above, the decision criteria boils down to essentially one axis: "Should this business operation be the same as other companies, or should it be different?" If being the same as other companies is acceptable, use a package solution. If you need to maintain company-specific approaches, go with custom development. That's it. In reality, both elements are often mixed together, so you can make the initial choice by considering the proportion of each factor.

That's all, Thank you for reading.
