A request for proposal is a document that a company writes to solicit bids from a supplier.
A request for proposal should provide the materials, equipment, and/or services being sought by the company or organization that will be purchasing them. It should also include specific requirements about what the item being sought should do and other circumstances about the purchase.
The RFP should also note how many items are needed and when they need to be delivered.
Lastly, it should specify how proposals can be submitted and who has access to them after submission. The company requesting the goods will typically examine proposals and make a decision based on price and quality considerations.
