Custom software or off-the-shelf: which suits a small business?

The short answer

In short.

If an existing product handles the job, it is usually quicker and cheaper. Custom software is worth considering when an important part of how you work is still unsupported, or when the real problem is information being copied by hand between tools. Write the requirements down first, then compare.

Write down the job

How does the work happen today, who does it, and which records are involved? A clear process makes any software easier to choose.

Check existing products

Look at features, limits, subscription costs and whether you can get your data out. Many small business needs are already well served.

When custom makes sense

When an important part of the process is not supported by anything available, when several tools almost fit but none does the key step, or when a customer portal or internal system needs to work your way.

Connecting, not replacing

Sometimes the useful work is connecting two tools you already use, so information moves between them without copying.

What to own

With custom software, the code, your data and the accounts it runs in should be in your business's name, with documentation another developer can pick up.

Plan for upkeep

Custom software needs looking after. Agree support and how future changes will be priced before you commit.

Protect the data

Whichever way you go, consider what personal information the tool holds. The Office of the Australian Information Commissioner has guidance for small businesses on handling it.

Custom software development versus off-the-shelf solutions

Off-the-shelf software is built once and sold to many businesses: a CRM, an accounting package, a booking system. You pay a subscription, you get updates, and the vendor carries the cost of development and security. Custom software is built for one business, so it fits exactly how you work, but you pay for the development and for keeping it running.

Integration often beats a full custom build

Many small businesses do not need either extreme. Connecting the software solutions you already use, so your CRM, booking system and accounts share data, often solves the real problem for a fraction of the cost of custom software development. Ask for that option in any quote before committing to a full build.

How long does a custom build take?
