# Price adjustments It is common in B2B to incorporate price adjustments into the pricing structure to account for inflation, for example. Another example can be that a customer negotiated a massive discount and in return allows the vendor to increase the price a certain percentage every year. Price adjustments in Bunny have three different settings: * **Do nothing** – no adjustment is made * **Adjust a percentage** – the subscription's prices are adjusted a percentage * **Copy from catalog** – the subscription's prices are updated with the latest from the catalog Price adjustment are performed on an account's billing day. Bunny tracks when an adjustment was last made and uses that date to see if prices need to be adjusted again on bill run. {% hint style="info" %} **Example:**\ \ An account's billing day is the 10th of the month. The price adjustment settings on the account are to adjust by 5% in July. When the account is process on July 10, all the prices on the subscription will be increased by 5%. {% endhint %} ### Product plan price list The price list in the product catalog contains default values for price adjustments. These will be copied to the quote builder and can be changed there. ### Self-service When you create subscriptions for self-service via Bunny's API, you generally want to use the **Copy from catalog** setting, since self-service customers usually agree to accept future price increases when they accept the terms of service. But you can of course use it the way you feel is best for your business. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
