Engineers, a consultant or a vibe-coding tool can all build software around your process. The difference shows up later, when the process changes.
Say a supplier emails an invoice, and the price is higher than on the purchase order. Here's what happens next in each case.
Engineers, a consultant or a vibe-coding tool writes software around your process.
Engineers write code for each check, and it does exactly what it was written to do. When the controller adds a rule, it waits on a ticket for whoever maintains the code.
Your team says which steps always run the same way and where the AI can use judgment. One agent follows those steps for the whole run.
Matching the invoice to the purchase order runs the same way every time. The AI decides whether the new price looks like a mistake, using your price list. Anything over a set amount goes to the controller, as a form with the invoice, the purchase order and a recommendation.
Each row is something you can check in a demo, or in the other tool's docs.
The tradeoffs depend on who turns what your team knows into working software, and who changes it later.
