Custom software or off-the-shelf: how to decide

Almost every company eventually reaches the same question: buy a ready-made tool or commission its own? The wrong choice costs money in both directions. Those who commission development for something a ready-made tool already does well pay for nothing. Those who spend years bending their business around a tool that does not fit pay as well, only less visibly.

When off-the-shelf is the better choice

Ready-made tools are good for work that is the same in most companies: accounting, email, payroll, video calls. You are not competing on these, so there is no reason to invent your own.

• The process is standard and does not set you apart.
• You need a solution now, not in a few months.
• The number of users is small, so the subscription is low.
• The tool connects easily with what you already use.

When custom software pays off

Your own software makes sense when the way you work is your advantage, or when ready-made tools simply do not cover what you need.

• Employees copy the same data from one system to another.
• A key part of the business runs in spreadsheets only one person understands.
• Subscriptions grow with every new user and feature.
• The data is sensitive and you want to know where it is and who can access it.
• The process is specific to your industry and no tool follows it all the way.

Five questions before deciding

• What exactly do we want to solve? If you cannot describe the problem in two sentences, it is too early both to buy and to build.
• What does the current state cost us? Add up hours of manual work, errors and subscriptions. That is the amount you compare every offer against.
• Who will use it? A tool chosen by management without the people who work in it rarely takes root.
• What must it connect to? Integration with existing systems is often a bigger job than the tool itself.
• What about three years from now? Estimate the total cost over a longer period, not just the price on day one.

The middle path

The choice rarely has to be all or nothing. It is often most sensible to keep ready-made tools for standard work and build only the part that is specific to you and connects them. That way the investment goes where it makes a difference.

If you are not sure which side you are on, analysis before development is usually the cheapest step in the whole project.
