is it possible to insert QR Code for payment. It would be much easier to pay invoices ??

Hi,

maybe in the future.

If for extending the licenses - then just extend for one year (or longer) and you won't have to do that often (it's also cheaper).

Edit:

I have added card payment via Stripe. It has option to save the card details so you won't need to enter them in the future. That's all I'm planning for now.
