# Backup & Synchronisation

All documents created within BestInvoicing are saved and stored on the platform with continuous server backup. In order to also save a copy of your documents on another platform, we provide a couple of (external) backup and synchronization connections.

* If you create a document in BestInvoicing, it will also appear in the connected platform
* If you modify or edit an existing document in BestInvoicing, the change will also happen on the connected platform
