Hi Josh - Purchase Quotation is used when your purchasers have contacted various vendors and each vendors have individually sent their quotations. Your purchaser would then enter the details of all these purchase quotes in NAV and run a comparison of which vendor is giving a best final total price of the goods/services you had requested. You create purchase quotes in NAV as a record of which all vendors showed interest in supplying you goods/services and what was each's price point. This will help the purchasers in your company always find the best offer + vendor. In Purchase quote, vendors provide the prices and delivery times for the quantities of items that they specify so you can keep track of everything a vendor may have committed to you
Once you have all purchase quotes entered, you'll choose the best one and just press "Make Order" to finalize the order from that vendor
I understand it seems a bit counter intuitive for a purchaser to enter all quotes received from vendors in NAV, but this data can be further pulled into Power BI or some DA tool to analyze which vendors have always been consistent in providing you the best services at competitive prices
Some companies use Purchase Quotes as "Requisition Request" Documents, I know these 2 documents are not the same, but standard business central has Purchase Quotes closest to a functionality you'd want in "Requisition Request"
