[Back](./) # Can I have a contact who is both a customer and a vendor? No, if a contact is both your customer and vendor, you’ll have to create two separate contacts - one as a customer and the other as a vendor and link them in Zoho Inventory. **Pro Tip:** A display name is generally unique for each contact. If you’d like to use an existing display name for another contact, go to **Settings » Preferences » Contacts** and tick the **Allow duplicates for contact display name** checkbox. #### Linking Contacts * Once you’ve created the contacts, open any one of them. * Go to **More** and click **Link to Customer/Vendor**. * Choose the Customer/Vendor that you want to link this contact to. Post linking, you view the payables and receivables in both contacts.
