# Do billing information updates affect past invoices?

Yes, when you update your billing information, the changes are applied immediately and will also be reflected on past invoices. 

However, invoices that have already been generated are not updated retroactively.

To update your billing information, please refer to the following article: [https://knowledgebase.xtenav.com/en-us/article/how-to-edit-billing-information-tdcmzy/](https://knowledgebase.xtenav.com/en-us/article/how-to-edit-billing-information-tdcmzy/)
