How to decide between custom software and an off the shelf tool

This is not an article arguing that every business needs custom software. Most do not, at least not yet. Off the shelf tools exist because most businesses run processes that thousands of other businesses also run, and paying a monthly fee for something already built is usually the right call. The question worth asking is not whether custom software is better, it almost always is, but whether your specific process is common enough that a general tool already fits it well.

Signs an off the shelf tool is still the right fit

• Your process looks close to how most businesses in your industry operate
• You have not had to build a workaround, a side spreadsheet, or a manual step to make the tool actually work
• The monthly fee is small relative to the time it saves
• The tool has room to grow with you for at least the next year or two

Signs it is time to look at custom software

• You are paying for three or four different tools and manually moving information between them
• Your team has built a workaround, a shared spreadsheet, a shadow process, because the software does not actually match how you work
• You are paying per seat for features most of your team never uses
• Your process is specific enough to your business that a competitor using the same off the shelf tool would run it differently
• The tool caps out at a certain size and you are approaching that cap

The real comparison is not the price tag

A monthly subscription feels cheaper than a custom build because the cost is spread out and small each month. But a workaround built on top of an ill fitting tool has a real cost too, in the hours a team spends manually reconciling data, in the mistakes that happen when a manual step gets skipped, and in the ceiling it puts on how much the business can grow before the process breaks. Custom software has an upfront cost and then largely stops costing you anything beyond hosting, because you own it outright.

A middle path most businesses miss

Custom software does not have to mean replacing everything at once. A focused build that replaces the single worst part of a process, the manual data entry step, the paper intake form, the spreadsheet three people edit at the same time, is often enough to fix the actual problem without the cost or risk of a full system replacement. That is usually where a first custom project should start.
