At Print.one, you work with prepaid credit (also called balance). This means that you first add credit to your account, and we then automatically deduct the costs for your sent cards from that balance.
As long as there is no credit available, you can create test orders, but they will not actually be printed or shipped. In that case, only a PDF file will be created to view the result. As soon as you have sufficient credit, your orders will be automatically processed, printed, and sent.
Topping up is easy via your account. You choose the amount you want to add yourself.
After payment, the balance is immediately visible in your account, and you can send cards again.
