I think with a SaaS you're trading user research and workflow design for a certain lack of customization, and that for 90% of businesses that will remain the right call. (And for the ones where it's not the right call, I think the contractor model also makes more sense than in-house LLM-generated-user-tool teams. That's a lot of code to pile up under a very small team for long-term maintenance. Yeah, "the agents can do it," but you're making ever-more balls that the people overseeing the agents will have to juggle over time.)

If you're selling honey online, say, how bespoke does your inventory management tool really need to be? And are there no lessons you'd learn from a SaaS tool that you'd not have thought of on your own?
