Pre-auths allow you to reserve funds in advance of a future transaction. During this time, while no funds have actually left the customer's bank account, these reserved funds are unavailable to the customer for other purchases. At a later time, you can then either adjust the amount, complete the purchase or cancel to release the funds back to the customer.
This has useful applications for many types of businesses. Common examples would be for customers booking a hotel reservation, which ensures the customer has the funds to pay for their stay without actually charging them until checkout. Other examples would be businesses renting out cars or other valuable equipment, to provide peace of mind against potential damage, loss or theft of said products.
