New requirements, new quote (which likely invalidates the old one.) If Bob offer one Whatsit for 10$, Alice can either accept this quote as it is, or request a new quote for 2 Whatsits.

@turnip If Alice has changed the request, the quote should be invalidated. Otherwise she could game the system: request a quote for one widget. Get a quote from Bob. Then change the request to 10 widgets and hit the "buy now" button before Bob has a chance to update the quote.

@Caleth yes, it looks like that could be the way to go. Currently "Alice" has more power when it comes to accepting an offer because accepting and payment is one step. If I introduce a separate "accept" step which both parties must carry out, then I can proceed with payment. What Hans is suggesting could work too.

@turnip - who are you making this for? Can you ask them how they handle changing requirements, how much negotiation they want to allow, and how they might want to structure the process? It may turn out that they have a way of doing it that avoids this problem completely.

@turnip in that case it's a new offer to a new set of requirements, the original quote keeps linked to the original set of requirements. Do NOT allow editing of quotes and requirements/order forms while quotes are being processed. If Alice changes her order, cancel the quote and issue a new one. If Bob notices he made an error in his quote, cancel the quote and issue a new one (if Alice hasn't accepted the existing one yet, in which case Bob has entered a legal contract and will need to renegotiate to fix that error).
