When does a business actually need custom software development?

I’ve been wondering at what point it makes sense for a business to invest in custom software instead of relying on off-the-shelf tools.

There are plenty of SaaS platforms available today, but sometimes they don’t quite fit the way a company operates. That’s where Software Development seems to become useful, especially when a business has specific workflows or needs integrations between multiple systems.

I recently came across Pigeon Tech while researching software development companies and was looking at the different types of solutions businesses can build.

For those who have gone down the custom software route, what made you decide it was worth developing your own solution instead of adapting an existing product?
