There are many millions of companies that are going to be re-examining if they can do better in the next years. The work will still be very complicated but with the help of AI, small IT shops might just deliver enough value to be worth the trouble.
The notion of e.g. busy floor plant/logistics managers vibe coding this themselves is silly. 1) they don't have the time; these people are super busy 2) they lack the ability. 3) they'll want it done properly 4) their employers won't skip all the certifications, iso stuff, and what not.
Companies invest in SAAS software if it delivers some kind of revenue/profit benefits. If it's too expensive/complex, it can't do that. AI tools lower the cost of SAAS solutions. So the totally addressable market grows. Companies will want to maximize their ROI though. So, they'll do the usual and engage software companies and integrators to help them do this. They'll expect to pay less for more. And there will be lots of haggling around that topic. But there's an enormous amount of companies that are quite far behind on getting their operations into this century in terms of IT already. There are going to be early adopters looking for early successes here that will put pressure on their competitors if they are successful.
I'm running a small company in this space. We're seeing a lot of opportunities right now. And AI is making my work massively easier already. All those complex ERP integrations just became an order of magnitude easier to do with a small team. They are still hard though. Forget about vibe coding that. You need a plan.
