A ______ auction is a type of reverse online auction where the buyer begins with a low initial price and gradually increases it until a supplier agrees to provide the item at that price.

A "Dutch auction." is a type of reverse online auction where the buyer begins with a low initial price and gradually increases it until a supplier agrees to provide the item at that price.

• However, in the context of reverse auctions, particularly in procurement and sourcing, where a buyer specifies what they want to purchase, and suppliers bid for the contract by offering lower prices, your description fits more with a "reverse auction" but with a twist in the method. Usually, a reverse auction starts with suppliers offering the highest price they're willing to accept and then they decrease their bids over time. However, in the scenario you described, where the buyer increases their offered price until a supplier accepts, it doesn't fall under a conventional auction type and is not a standard practice for reverse auctions. It may be a unique or specialized type of reverse auction created for a specific context or as an alternative procurement strategy.
