You can activate a functionality in your Payrexx account which will create a user account for a customer after he's made his first payment on your shop.
If you activate this function, your customer will receive an email with the access data directly after the payment confirmation.
Your customer can then log into his user account through your Payrexx shop. Once he's logged in, he can then view the payments he's made, or if he's made a subscription payment, he can manage his subscription.
How to enable this functionality:
1. Navigate to settings -> general settings in your Payrexx backend.
2. There you will find the section "General" at the top.
3. Check "Create user accounts for all transactions" to enable this feature.
