In this tutorial, you sign in to the Partner Portal for the first time and add your first customer.

## Before you start

- Zimple made your Pipedrive company a Partner.
- You installed OneClick in the Pipedrive company of your Partner. See
  [Install OneClick as a user](/docs/getting-started/install-as-a-user).
- Your customer installed OneClick in its own Pipedrive company. See
  [Install OneClick as a global admin](/docs/getting-started/install).
- You know the Pipedrive subdomain of your customer. The subdomain is the part before `.pipedrive.com`, for example
  `acme` in `acme.pipedrive.com`.

## Get portal access

Zimple gives portal access to the first user of a Partner.

1. Send an email to Zimple support at [support@theoneclick.io](mailto:support@theoneclick.io). Ask for portal access
   to the Partner Portal. Give the name of your Partner and your Pipedrive email.
2. Wait until Zimple support tells you that you have portal access.

After you have portal access, you give portal access to the other team members on the **Users** page. See
[Give a team member portal access](/docs/partner-portal/users/give-a-team-member-portal-access).

## Sign in

1. Open [partners.theoneclick.io](https://partners.theoneclick.io). The page **Sign in** opens.
2. Click **Continue with Pipedrive**. Pipedrive opens.
3. If Pipedrive asks you to sign in, sign in with your Pipedrive account.
4. If your Pipedrive user has access to more than one company, select the Pipedrive company of your Partner.
5. Allow the Partner Portal to use your Pipedrive account. The **Dashboard** of the Partner Portal opens.

If the Partner Portal shows **You don't have portal access.**, see
[You don't have portal access](/docs/partner-portal/getting-started/you-do-not-have-portal-access).

## Add the customer

1. In the sidebar, click **Customers**. The **Customers** page opens.
2. Click **Add new**. The window **Add new customer** opens.
3. In **Tenant subdomain**, type the Pipedrive subdomain of your customer. If you paste a full Pipedrive URL, the
   field keeps only the subdomain.
4. Click **Next**. The window shows the name and the subdomain of the company under **Organization**.
5. Make sure that the company is your customer. If it is not, click **Back** and type the subdomain again.
6. In **Seat limit (0 = unlimited)**, type the maximum number of customer users. Type `0` for no limit.
7. Click **Add customer**. The Partner Portal shows **Customer added.**

The customer is now a row on the **Customers** page. **Used** shows the seats that the customer uses. **Limit**
shows the seat limit. **∞** means no limit.

## If the customer does not add

The window **Add new customer** shows the error under the field. For each message and its fix, see
[If the customer does not add](/docs/partner-portal/customers/add-a-customer#if-the-customer-does-not-add).
