I want to use recurring invoice and send those invoice on a yearly base to my customers.
I the invoice there is a webhosting abo.
The recurring invoice should display the period for the abo.
So The invoice send (as an example) in 2018 should say:
Abo from 01-03-2018 to 01-03-2019
The Invoice send in 2019 should say:
Abo from 01-03-2019 to 01-03-2020
I send the invoice 60 days before the start of the new period so I was thinking to use in the e-mail template somthing like:
`The invoice is for the period {{{{invoice_date_created}}} + 60}.`
Is there a way to calculate the date value or does anyone have any suggestions how to solve my problem
