Hello,

As of now you can't edit invoice paid date from backend. You can update the subscription date's only.
Paid date will be saved when payment made successfully.

Let me know if you have any query.

ok
The pb is that I had an old website with maybe 200 invoices of Payplans.
I have done a completely new website and I need to import those invoices (to the users of the new website that were already in the old website).
That's why I thought first to recreate all the invoices, with putting the date of the payment : but if this is not possible, I am in trouble
Would there be a way to import ?

Hello,

As of now there is no functionality to import invoice data.
You can write a script to import these dates or you can change it manually from database table also.
You need to change in #__payplans_invoice table and column name is paid date.

Let me know if you have any query.

Thanks
It will not be the easiest way to do it, but at least it works.

ok
