Relationship-based pricing

Relationship-based pricing (RBP) is a pricing and billing framework in the banking industry where pricing is determined based on a customer's overall purchases and circumstances, rather than being delivered on a product-by-product basis. With RBP, banks use customer-based parameters, such as the level of overall business the customer does with a bank or the types of services purchased, to determine pricing.
