Once you know Paligo is for you, it's easy to purchase your licenses. You can either purchase directly from within your trial and pay directly by adding a credit card:
Or just contact Sales at firstname.lastname@example.org and someone will get back to you to set up your subscription right away.
For monthly payment, the standard payment method is credit card. If you select an annual plan, you also have the choice to pay by invoice and bank transfer.
(Note that even if you pay by credit card, you will of course get an invoice receipt at every renewal!)
