By enabling Card payments you can use the service of PayPal to collect payments from your customers. A Pay Now button appears on your invoices and your customers can pay you instantly.
A customer can pay an invoice by credit/debit card or by PayPal, in some countries by iDeal or Sofort as well (depending on your local PayPal settings).
Navigate to Settings – Payment options – PayPal
Turn on Accept online payments
Enter your PayPal account email
NOTE: Linking PayPal with Billdu is currently disabled. Your customers can still pay you, the money will be transferred to your PayPal account but your invoices won't be marked as paid automatically and we send no notifications as well
Save the settings
A Pay Now button is now visible on your invoices and your customers can pay you by PayPal. Only a customer with a PayPal account can pay you by card.
