# Contact management overview

> Understand how Upflow imports and updates customer contacts from each native integration and the rules that govern main and additional recipients.

By default, your contacts are continuously imported and updated from your billing or accounting tool. Their specifics depend on your integration.

| **Integration** | **In your billing tool**            | **In Upflow**                                                                                                                       |

You can alternatively [connect your Salesforce account](/en-us/integrations/salesforce/connect) to your Upflow organization(s), making your CRM the source system for your contacts.

***

❗Upflow information will mirror those of the designated source (CRM or billing tool), so any update you want to see applied must be performed there.

***

If your contacts are not managed in your billing tool and you are using a CRM not yet integrated with Upflow, you can manage them directly from Upflow. This includes bulk imports and adjustments on the fly — even while sending a reminder! You can also refer to the [API documentation](https://upflow.docs.apiary.io/#reference/0/contacts).
