# Rates The '*Rates*' screen allows you to configure manual rates for services that do not have a rate provided with their data source. Before you can use this screen, it is required to [create](https://github.com/exivity/docs/tree/4455d34021b8c3e12ce1b09914544d96f4a3b270/transform/language/service/README.md) the necessary service(s) via the [**Transcript** ](/2.10.2/services/rates.md)engine. When that requirement has been fulfilled, you may configure *Global* and customer specific rate configurations. The following rate types are currently supported for *automatic*, *daily* and *monthly* services: * automatic per unit * automatic per interval * automatic per unit & interval * manual per unit * manual per interval * manual per unit & interval *Automatic* services obtain the rate and/or interval value from a column you specify, whereas *manual* services allow the user to manually specify a rate and fixed interval money value. For *manual* services, if a *service definition* has *proration* enabled, the charge on the cost reports is calculated based on the actual consumption (see [services](/2.10.2/services/rates.md)). By default each service has a ***global*** rate configured, which will be applied to all ***accounts*** that consume this service. However, it is possible to use customer specific rates by overriding a ***service*** rate for one ore multiple accounts. ## Edit global rate for a manual service A ***manual*** service can have up to 3 rate values that can be changed: the ***unit*** rate, the ***interval*** money value and the ***COGS*** rate. To change these values, go the '*Services*' > '*Rates*' screen and click on the **service** name for which you want to change the global rate value: ![change rate for manual service](/files/-LHF0U4qR91kCQBxM2nn) To change the rate values of this service, consider the following: 1. *Effective date* is the date from when this rate is applied to the service. A service can have one or multiple revisions. You may add new rate revisions by using the ***Add Revision*** button. Existing rate revision dates can be changed using the ***Change Date*** option 2. The ***Per Unit*** rate value is the value that the service charged for, every (portion of) configured interval service. In this example, if this would be a *daily* service that is charged 1 euro per Gigabyte of database usage, and each day a 100 GB database is consumed, a value of € 100 will be charged per day (and € 3100 if used for entire month of December) 3. The ***Per Interval*** charge is applied every occurrence of the consumed service, regardless of the total consumed quantity of that service. In the previous example at ***2***, this would mean every day a value of 110 euro will be charged for a 100 GB database: 100 euro because of the standard rate + 10 euro for the fixed interval charge. Considering the same consumption for the entire month of December, the total charge for that month will be 31 x € 110 = € 3410 4. It is possible to configure a ***COGS*** rate for this service. This is applied the same way as the ***Per Unit*** rate 5. To delete an invalid or wrong revision, use the ***Remove Revision*** button. Do bear in mind you cannot delete the last rate revision for a service 6. To save your changes, which will also initiate a re-preparation of the applicable ***Report***. click the ***Save Revision*** button *(see* [*defining reports* ](https://github.com/exivity/docs/tree/4455d34021b8c3e12ce1b09914544d96f4a3b270/gui/reports/defining_reports/README.md#preparing-a-report-definition) *to learn more about report preparation)* 7. If you are planning to make more changes to other services in the same report definition, use the ***Save Revision*** > ***Without Preparing*** option. This will avoid running the re-preparation several times, and allows you to start the re-preparation only after you've made all of the required rate changes. --- # 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.
