Bespoke, without bloat.
The question is no longer whether you can build. It is when building beats a licence that does ninety percent of what you do not need.
The standard licence and its excess weight.
A standard tool wants to be everything to everyone. You pay for features you never use, and you bend your work to the tool instead of the other way around. For many organisations that was long the only option. It is not anymore.
What changed the maths.
In the last fifty days I built around forty, all working. Bespoke software is no longer a luxury that costs months and a team. For those who can, it is a matter of days. That shifts the trade-off. Not buy because building is too expensive, but build what fits exactly, and buy the rest.
When buying does win.
Honestly, because dogma helps no one. For commodities, you buy. For what needs heavy, ongoing maintenance, you buy. For what the market already solves perfectly, you buy. Building is not a goal in itself. It is a choice you make where bespoke truly adds something.
The rule I hold to.
Build what solves exactly your problem, and nothing more. Buy the rest. The difference between building and buying is, at its core, the difference between fit and bloat. An internal application that does one thing well beats a platform that does ten things halfway. Every time.
