# How is a Partner Network invoiced? You can integrate MessageBird’s services, such as SMS, using our [APIs](https://developers.messagebird.com/api/) to deliver these services to your customers. Although your customers essentially consume MessageBird’s services, keep in mind that you are responsible for paying MessageBird for those services. You will receive an invoice from MessageBird at the end of the billing cycle, which will include the charges for each *main* and *child account*, as well as the total invoice amount that is due. This also means that you will be invoiced using the billing currency of the main account. You may choose to recover those costs from your customers using the consumption information of each *child account*. --- # 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.
