Custom software or an off-the-shelf package? How to choose

Choose an off-the-shelf package if your process is largely standard, and custom software as soon as the exceptions become the rule. That is the short version of the decision. A package is faster and cheaper on day one, while custom software fits exactly around your way of working and charges no licence per user. This article makes that trade-off concrete, including the cost comparison most comparisons skip.

When is an off-the-shelf package the better choice?

An off-the-shelf package wins when you can adapt your way of working to the software without much pain. For accounting, invoicing, email marketing or a simple webshop there are excellent packages shared by millions of companies. Building something yourself that does the same thing is burning money.

Stick with a package if:

1. Your process looks like that of thousands of other companies.
2. The standard functionality covers 90% or more of your needs.
3. You can afford to adapt your way of working to the tool.
4. You want to start quickly and the monthly cost stays acceptable.

When does custom software pay off?

Custom pays off as soon as you notice you are working around your software instead of with it. The signals are recognisable: you pay licences for five tools that each do 80%, your team retypes data from one system into another, or your most important process is hidden in an Excel file nobody dares touch any more.

The real rule of thumb is the number of exceptions. Every company has a way of working that deviates slightly from the norm, and that deviating part is often exactly your competitive advantage. If that advantage gets squeezed because a package cannot handle it, that is the moment for custom software.

The real cost comparison

Most comparisons put the build price of custom software next to the monthly price of a package, and then custom always looks expensive. That holds on day one, and it leaves out most of the story. Do the sums over three to five years.

A team of ten that grows to thirty sees the licence cost of a package multiply by ten, while the cost of custom software is largely behind it. What weighs heaviest in your case depends on your team size and how long you want to use the software. Just do the sums for both.

The grey middle: a package with custom software around it

The choice is rarely black and white. Often the best solution is to keep your good packages and build only the missing piece to measure, with integrations in between. Your accounting stays in your accounting package, your email in your email tool, and around that comes one custom platform that closes the gaps and makes the systems talk to each other. That way you pay for custom software only where it delivers something. How such a project runs and what it costs is covered in what custom software costs.

An honest decision rule

Walk through these three questions before you decide:

1. Is my process standard? If so, start with a package.
2. Are the exceptions rare, or the very core of my business? If they are the core, custom wins.
3. Is my process simply messy? Then software will not fix it. Clean up your process first, whether it ends up a package or custom software.

Most sellers skip that third question, because the answer sometimes costs them a project. We ask it anyway, because software wrapped around a bad process only gives you a faster bad process.
