# Managing Contacts
Memorizing wallet addresses is impossible. It's much better to assign a name to the address. Integral has two main ways to assign contacts to wallet addresses: (1) Add a single contact from Bookkeeping; or (2) Upload a CSV of your contacts.
## Add a Contact from Bookkeeping
Creating a new contact from the Bookkeeping page is easy. Whenever you come across a transactions from/to an address you know, simply **hover over the address** and **select Add Contact**.
### **Link Contact**
Integral imports your customers and vendors from your ERP (QuickBook/Xero). Linking an address to an existing contact, or to an ERP customer/vendor automatically imports all their information so everything stays in sync. This is also required to push customers/vendors as part of journal entries. This is the preferred method.

A single contact can have multiple addresses across chains associated with them. You can link an existing contact to additional wallet addresses.
{% endhint %}
### **Add Contact**
This creates a new contact in Integral. You must associate the address with a contact name, and optionally Company and Email. At this time, Integral does not publish customers or vendors to your ERP.

### Add Contacts in Bulk Using a CSV
If you prefer to import contacts you already have documented:
1. Navigate to the [Contacts page](https://app.integraltreasury.xyz/contacts/integral)
2. Download the template by clicking `"Import Contacts"` > `"Download Template"` in the top-right corner
3. Fill in the information (address, chain, and name are required\* fields)
4. Click on `"Import Contacts"` > `"Upload CSV"` in the top right corner to select your file
5. Review the preview to make sure the information is correct, then click `"Import X Contacts"`
That's it! All your contacts have been imported, and your transactions updated with their names.
### **Delete a contact or a contacts wallet**
To delete a contact and remove it from any transactions, navigate to the [Contacts page](https://app.integraltreasury.xyz/contacts/integral). From here, you can either delete a contact entirely or simply delete one of the contacts' wallets.
1. Select the customer(s) you want to delete using the checkboxes on the left.
2. Click `"Delete"` in the bulk actions bar at the bottom of the page.
To delete a wallet of a contact but not the contact itself:
1. Click on the contact and then Wallets
2. Click the edit button beside the wallet you want to delete, and then `"Remove"`.

1. Go to Bookkeeping
2. Find a transaction related to the contact
