There are a number of reasons why the price of your Coreo licence subscription might change. The overall licence fee for Coreo is reviewed annually (usually in January) and costs may increase due to rising 3rd party service charges, inflation and other costs related to providing the service. Your subscription costs may also change due to opting to add or remove certain features or products, or when moving between subscription tiers. If you have an Enterprise licence, costs will be set for the contractual term of the licence and may be subject to change upon renewal, as above.
