AI quoting software vs should-cost software: what is the difference?

AI quoting software reads a specific customer's RFQ and prices it with the shop's own rates and history. Should-cost software simulates what a part ought to cost, independent of any one RFQ, using a cost model the vendor supplies or the buyer configures. One answers 'what should we charge for this enquiry'; the other answers 'what should this design cost to make'.

What problem does each one solve?

AI quoting software exists to turn a specific, real RFQ into a priced quote fast, using the numbers a shop already trusts. Should-cost software exists to answer a design or sourcing question, what a part ought to cost to make, before or independent of any particular customer's enquiry, often to negotiate with a supplier or evaluate a design change.

Where does each one's price come from?

AI quoting software carries no cost model of its own: the shop's own rates, margins and quote history do the pricing, applied to whatever the current RFQ contains. Should-cost software runs a cost simulation, built from manufacturing process models, material data and cycle-time estimates that the vendor supplies or the buyer configures, largely independent of any one shop's own rate card.

Can a shop use both?

Yes, and they are not competing for the same job. A should-cost estimate can set a target or a ceiling for what a part ought to cost; AI quoting software then produces the actual customer-facing quote against a specific RFQ, using the shop's own rates rather than the should-cost model directly.
