I can't count the times I've told clients and prospects to _not_ hire us to build something they wanted. Because they could just use off the shelf solutions that were cheaper financially, at least in the short to mid term, and much, much cheaper in terms of opportunity costs. I struggle to put even billed hours into something that doesn't make sense to me.

Of course some overdo it. I've seen companies with more random SaaS tools than staff, connected with shaky Zapier workflows, manual processes, or not at all. No backups, no sense of risks, just YOLOing. That's OK in some cases, in others really not.

I suppose it does need some engineering thinking to find the right things and employ them in a good way. Unfortunately even developers commonly lack that.
