Think you need to narrow down what is exactly being purchased.
Not sure whether you mean something like 'find me a cheap SAAS for CRM' and it comes back with quotes for various monthly subscriptions, or if it's something like 'I need 500 bottles of ketchup for my BBQ business' and it comes back with 'go to store x and buy y for price z' ??
not enough info to answer:
> i am looking to charge $500/mo for it.
AI tools need to answer:
a) Can you save me more than that by using your tool?
b) Can I just do it myself by prompting Claude or ChatGPT or Copilot or whatever. You kind of need your own data sources or deals with suppliers/providers of whatever you are offering to find for cheaper that Agents doing web search cannot find or use to have any kind of edge here.
