CPQ is great when your reps benefit from guidance and structure. Yes a process is good/needed - that's what you implement and what the tool should support. This is a great way to work when you sell on multiple markets, have different discounting rules, have acquired companies and therefore have a higher complexity in your product catalogue. If this is not your case then a CPQ might be too much.
To vibe code is a great alternative when pricing and products are straight forward and seldom changes over time. When it gets complicated is to maintain it over time due to version handling, support for edge cases, to understand why a price was calculated in a certain way but most importantly:
Today’s AI can hallucinate, misunderstand intent, or confidently generate incorrect pricing logic.
The same prompt can also produce slightly different outputs over time, which is dangerous for CPQ. For CPQ, the final pricing engine must be truthful, deterministic, explainable, and repeatable.
Until it is, it's just the same thing as not using a CPQ - you just can't garanti error free quotes. And that will cost you both growth and profits.
