# Bulk Customer Deletion

{% hint style="danger" %}

### Before you begin

#### This action permanently deletes member data

Bulk Customer Deletion **fully deletes the member’s data from Inveterate**. After deletion, it is as if the customer was never a member in the first place. This cannot be undone.

Use this only when you are certain you need to permanently remove a member’s membership record (for example, data cleanup requests or internal testing accounts).
{% endhint %}

#### CSV requirements

To delete members in bulk, you must upload a CSV that includes a header named:

* `customerId`

(You’ll see this requirement called out directly in the upload modal.)

### How to perform a Bulk Customer Deletion

1. **Navigate to your Inveterate dashboard**. 
2. Go to **Settings**. 
3. Select **Bulk Actions**. 
4. Click **Actions** (top-right). 
5. Choose **Customer deletion**. 
6. Upload your CSV file containing the members you want to delete. 
7. (Optional) Add an internal note to accompany the deletion request. 
8. Click **Submit** to start the deletion process.

***

### What to expect after submitting

* Inveterate will begin deleting members included in the uploaded CSV. PerformBulkCustomerDeletion-4e6…
* Deleted members’ records are fully removed from Inveterate.

***

### Best practices

* **Double-check your CSV** before submitting (especially the `customerId` column).
* **Start with a small test CSV** (1–2 customers) to confirm you’re deleting the intended records.
* Use the **optional note** to document why the deletion was performed for future internal reference.
