# Bidder Registration and Approval

Use the **Registration & Verification** card under **Settings > Auctions** to control who can bid and what information customers must provide before bidding.

> **Note:** Bidder Registration is available on the **Grow plan and above**. See [Plans & Billing](https://admin.shopify.com/apps/auction-plus/plans) for more details.

## Auction Participant Modes

In the **Registration & Verification** section, choose one of these options under **Auction participants**:

### All customers

Any customer with a store account can bid. No extra registration or approval is required.

### All registered customers

Customers must complete a registration form before placing their first bid. After they register, they can bid right away.

### Invited customers

Only pre-approved customers can bid. Choose whether to require customers to fill out a registration form to request access, or link to a custom page with instructions on how to get approved.

See [Invite-Only Options](#invite-only-options).

## Registration Fields

When registration is enabled, you can choose which fields to collect:

* **First and last name**
* **Phone number** as required or optional
* **SMS marketing consent** when phone collection is enabled

The SMS consent text can be customized from [Translations](/translations/multi-language-support.md).

## Registration Logo

You can brand the registration form with a logo. Available options include:

* **Shop Logo**
* **Import from theme**
* **Custom URL**

You can also control the displayed logo width.

## Invite-Only Options

When **Invited customers** is selected, you control two things: whether customers fill out a registration form, and the behavior of the bid button for unapproved customers.

* **Require registration** — Show a form to collect name, phone number, and SMS marketing consent. Use this if customers should request access through the form.
* **Disable registration** — No registration form is presented to customers. Useful when access is gated by a purchase or subscription. This option can be paired with **Automatically approve customers with purchase history** to auto-approve customers who have purchased a pass, subscription, or other product on your store.

### Require registration

Under **Registration access**, choose who sees the form:

* **Allow anyone to register** — Anyone who has not registered are presented with the registration form after clicking the bid button. Submitting it creates a pending request on the Customers page for you to approve or reject.
* **Only approved customers can register** — The form is only shown to customers you've already approved (by email, phone, or another process). Unapproved customers are directed to a URL you specify — typically a page explaining how to request access. Best for private or invite-only auctions.

### Disable registration

The customer will not be presented with a registration form, and can start bidding immediately after you approve them from the Customers page.

Under **Unapproved customer action**, choose how the bid button behaves for unapproved customers:

* **Link to a page** — The bid button links to a URL you specify (for example, a page explaining how to request access).
* **Hide bid button** — Unapproved customers see the current price and countdown, but the bid button is hidden until they are approved.

## Purchase History Approval

Select this option to automatically approve customers who have previously purchased from your store.

## Approving Customers Manually

1. Open the **Customers** page
2. Filter to customers awaiting approval
3. Open the customer record
4. Approve or remove bidding approval as needed

> You can bulk approve or unapprove customers from the customer list view. See [Bulk Customer Actions](/customers-and-bidders/bulk-customer-actions.md) for details.
