Custom software vs. off-the-shelf: how to choose

We build custom software, so you might expect us to say custom is always better. It is not.

Off-the-shelf software is often the right answer. Custom is sometimes the right answer. The skill is knowing which situation you are in.

When off-the-shelf is the better choice

If a ready-made product does what you need, use it. It is usually the simpler path.

Your process is common. Accounting, payroll, email, basic customer records. Thousands of businesses do these the same way, and good products exist.
The product fits with little change. If you can adopt the product's way of working and nothing important suffers, take the easy road.
It is not where you stand out. If a process is not part of what makes your business different, there is little reason to build something special.
You want a vendor to maintain it. A product has a team behind it, with updates and support built in.

Do not build what you can buy and be happy with.

When custom starts to make sense

Custom becomes worth considering when the ready-made options keep falling short.

Your process is unusual. Maybe your product, your customers or your way of working is not what standard tools expect.
You are working around the software. Your team keeps a spreadsheet next to the product to fill the gaps. Or they do half the work in the tool and half by hand.
Your systems do not talk to each other. People copy data from one place to another because nothing connects them.
Your rules are specific. The way you price, schedule or choose a supplier is particular to you, and no product handles it.
The process is a competitive edge. If how you do something is part of why customers choose you, you may want software shaped around it.

A middle path

It is not always one or the other. Many good solutions mix both.

Keep your off-the-shelf tools for what they do well.
Build connections between them, so data moves on its own.
Add a small custom tool for the one process nothing else covers.

This often costs less effort than replacing everything, and it keeps what your team already knows.

Questions to ask before you decide

What exactly is the problem? Write it down in one or two sentences. If you cannot, you are not ready to choose.
Can a ready-made product do this? Look honestly. Try a few. Ask the people who would use them.
How much would we have to change? Changing your process to fit a product is fine if the change is good. It is not fine if it makes you worse at what you do.
Who will maintain it? A product has a vendor. Custom software needs someone who can fix and update it. Ask how that works before you start.
What happens if the need changes? Think about where the business is going, not only where it is today.
Who owns it? With custom work, ownership and access terms should be clear in the agreement. Ask early.
What is the cost of doing nothing? Look at the time, delays and errors that the current setup creates.

Warning signs on either side

For off-the-shelf: you buy a large product and use a small slice of it, or your team builds more workarounds each month.

For custom: you cannot describe the problem clearly, or a perfectly good product already exists and nobody tried it.

The honest answer

Start with the problem. Look at ready-made options first. If one fits, use it. If none do, or if you are stitching several together with manual effort, custom work or custom connections may be worth it.

If you are unsure, describe your process to us. We will tell you what we think, including when we think you should buy a product instead.
