invoiceninja subscription

I have already paid the pro version.
I want to upgrade to the enterprise version for a year
Can you upgrade my subscription and send me an invoice so i don’t pay too much ?

Hi, i have paid 80$ for the pro plan and want to upgrade to the enterprise plan and want to pay yearly.
However i have changed subscription and i have to pay each month 12$. I want to pay yearly and i want to get an invoice of 120$-80$

Can you change this pls

You can change your plan on Settings > Account Management, you’ll be credited for any unused time.

hi my 80$ isn’t taken into account ?
i had a subscription last year in november till next year november
so if i switch plan i don’t have to pay 120$ ubt 120-80 = 40$
