When custom software is worth it, and when it is not

Most businesses should start with software someone else maintains. It costs less to begin with, it improves without you paying for the improvements, and the problems it solves are usually the ones everyone has.

But there is a point where the tool stops fitting the business, and the business starts bending to fit the tool. These are the signs we look for before recommending anything custom.

1. The spreadsheet that runs everything

A file with a dozen tabs and one owner sits between your systems. It holds logic nobody has written down and nobody else can safely change. It works until that person is on leave, or leaves.

It is a single point of failure with a name, and the clearest sign that the business has requirements its software does not meet.

2. Paying per seat to work around it

You pay licences for a platform your team uses at a fraction of its capability, then add manual steps to make it do what you actually need. The monthly bill rises while the fit gets worse.

3. Your advantage is the process

The way you quote, schedule or fulfil is genuinely different from your competitors, and that difference is why customers choose you. Generic software is built for the average business, so it quietly pulls you back toward how everyone else works.

If none of these apply

Stay with what you have, and connect it better. Integrations between the tools you already pay for often remove most of the retyping without a single new screen.

If they do

Custom is worth it when the process is the product. When you commission it, a few things are worth insisting on:

• A map of how work actually moves, agreed before anything is written.
• Working releases you can use every week, rather than one reveal at the end.
• Documentation written as the system is built, and your team trained to run it.
• Your data, domain and accounts held in your name, exportable at any time.
• What you will and will not own at the end, stated in writing before you sign.
