The Waitlist keeps the Pipedrive subdomains that your Partner pre-claims. Each Waitlist entry has a subdomain and a
seat limit.

## What a Waitlist entry does

When the company of a Waitlist entry installs OneClick, OneClick links the company to your Partner as a customer. The
customer gets the seat limit of the Waitlist entry, and OneClick removes the entry from the Waitlist.

The company then shows on the **Customers** page. You do not add it as a customer yourself. See
[How seats are counted](/docs/partner-portal/customers/how-seats-are-counted).

Use the Waitlist only for a company that did not install OneClick yet. If the company installed OneClick, add it as
a customer. See [Add a customer](/docs/partner-portal/customers/add-a-customer).

Before you start, make sure that you know the Pipedrive subdomain of the company. The subdomain is the part before
`.pipedrive.com`, for example `acme` in `acme.pipedrive.com`.

## Add a Waitlist entry

1. In the sidebar, click **Waitlist**. The **Waitlist** page opens.
2. Click **Add new**. The window **Pre-claim a domain** opens.
3. In **Tenant subdomain**, type the Pipedrive subdomain of the company. Type only the subdomain, not the full URL.
4. In **Seat limit (0 = unlimited)**, type the maximum number of customer users. Type `0` for no limit.
5. Click **Add to waitlist**. The Partner Portal shows **Domain added to waitlist.**

The subdomain is now a row on the **Waitlist** page. **Seat limit** shows the seat limit. **∞** means no limit.

To find an entry, type a part of the subdomain in **Search subdomain**.

## If the entry does not add

The window **Pre-claim a domain** shows the error under the fields:

- **Request failed (400)**: the subdomain has a character that is not permitted, for example a dot. Type only the
  subdomain, not the full URL. Use only letters, digits and hyphens.
- **Subdomain already in your waitlist**: the subdomain is already a Waitlist entry of your Partner. To change its
  seat limit, see [Edit or remove a Waitlist entry](/docs/partner-portal/waitlist/edit-or-remove-a-waitlist-entry).
- **Subdomain already claimed by another partner**: the subdomain is on the Waitlist of another Partner. Contact
  Zimple support.
- **Organization already assigned to a partner**: the company installed OneClick and is a customer of a Partner. If
  the company is not on your **Customers** page, contact Zimple support.
