Not every problem deserves custom software.
And not every process should be distorted to fit inside a SaaS product.
The buy-or-build decision usually improves when we stop debating preferences and start asking uncomfortable questions:
Does this capability truly differentiate us?
How much would we need to change our operation to fit the product?
Who controls the data, and how difficult would it be to leave later?
Is the need stable, or are we still learning what it is?
Do we have the capacity to operate what we build, not merely launch it?
Buying can save construction effort and add constraints.
Building can provide control and create permanent responsibility.
There is also a third answer: buy what is common, build only what differentiates, and integrate both sides carefully.
The best option is not the one that feels more technological.
It is the one that makes its costs, limits, and the consequences of changing course later visible.
