# How do I access my invoices or change billing details?

> Access your SecureMailMerge invoices, update your payment method or credit card, and manage billing details for your subscription.

How you manage billing depends on how you purchased your subscription.

## Purchased via credit card (Paddle)

If you purchased through our website with a credit card, your payments are processed by Paddle. Invoices are sent automatically to the email address used during checkout.

**To access invoices or update payment details:**

1. Log in to [licensing.solinventum.com](https://licensing.solinventum.com)
2. Click on your subscription
3. In the subscription menu you'll find direct links to:
   - **Invoices** - view and download all past invoices
   - **Update payment method** - change your credit card details

If you can't find an invoice in your inbox, check your spam folder. The email comes from Paddle (help@paddle.com), not SecureMailMerge directly.

## Purchased via Microsoft 365 (AppSource)

If you purchased through Microsoft AppSource using Microsoft 365 billing, your invoices are managed through Microsoft's billing system.

**To access invoices:**

1. Go to the [Microsoft 365 admin center](https://admin.microsoft.com)
2. Navigate to **Billing > Bills & payments**
3. Find your SecureMailMerge subscription in the list

## Need invoices sent to a different email?

If you need invoices sent to a different email address (such as accounts payable), you have two options:

1. **Forward invoices**: Set up email forwarding rules for Paddle emails
2. **Delegate access**: In our licensing server, you can grant another user delegated access to view invoices and manage the subscription

## Changing the subscription owner

The subscription is tied to the Microsoft 365 account that made the purchase. To transfer ownership to a different account, you'll need to cancel the current subscription and have the new owner purchase a fresh subscription. Contact [help@securemailmerge.com](mailto:help@securemailmerge.com) if you need assistance.
