How to search for non inventory items within quotes

I like how manager is able to display the purchase invoice transactions for a particular inventory item. I would like to know if this is possible to do the same but for quotes, and also items that have been quoted but are not part of the inventory system.

Our main issue being that sometimes our customer creates their order with wrongly priced items and we have to check our quotes to see if they correspond. They don’t include our referrences in their purchase order so we end up looking through each quote we made to that particular customer for a specific item. If theres a way to solve this aside from my query above, please let me know.

You cannot search sales quotes, because they are not financial transactions in Manager. The only thing that might partially satisfy your desire is to search the transaction-level descriptions visible on the Sales Quote tab listing.
