Custom software or off-the-shelf? A practical way to decide

When a process outgrows spreadsheets, the first question is usually whether to buy an existing product or build something custom. Both can be the right answer. The useful question is which option fits your situation, today and over the next few years.

Questions to ask first

• How standard is the process? Accounting, payroll and email are well served by existing products. Processes that differentiate your organization often are not.
• How much would you need to change your way of working to fit the product — and is that change an improvement?
• What does it need to integrate with? A product that cannot exchange data with your other systems creates manual work.
• Who owns the data, and can you export it if you change direction?
• What is the total cost over several years, including licenses, customization, training and support?

When off-the-shelf makes sense

If a mature product fits most of your needs, adopting it is usually faster and cheaper than building. Choose products with good export options and APIs, so you are not locked in.

When custom software makes sense

Custom software is worth considering when your process is central to how you deliver value, when products would force significant workarounds, or when you need several systems to work together in a specific way.

The hybrid option

Often the best answer is both: proven products for standard functions, connected by custom integrations or a focused custom application for the part of the work that is genuinely unique.
