Whenever, you enable portal access, an invitation mail will be triggered automatically from [Zoho Billing](/fr/billing/ "Zoho Billing"). Your customers need to accept this invitation in order to access the portal. To enable the customer portal for a contact for the first time, in the **Customer Details Page**, under the **Overview** tab, scroll down and click on the **Enable Portal** option that appears on the left bottom. In the pop-up that follows, you will have to select the contact persons, to whom you wish to grant portal access. You can also re-invite your contact to the portal. To do this please follow the below steps: * Go to **Customers** tab and select the appropriate contact. * On the bottem left of the **Overview** tab you will find Contact Persons list. * Click the **gear** icon next to the contact person you wish to **Reinvite** and select the said option. An invitation mail with a link to set up a password will be sent to the contact person. On clicking the invite link, Zoho Billing will open up another page where your client can create a password to login to your portal. Once they login, they can view their invoices, quotes, subscriptions, payment history and make payment via secure payment gateways.
