Can you please post your URL, WP admin details and also FTP details in a private reply, so we can check things out for you.

Thanks

Please review https://wpinvoicing.com/support/topic/customer-invoice-email-not-sending/#post-3750
I think that has the answer for you.
Thanks

Have a look at
Invoicing > Emails tab > Due Date Settings

Thanks

For selling items, you can just use the Buy Buttons: https://wpinvoicing.com/docs/core-plugin/core-shortcodes/#buy-button

But maybe I am misunderstanding what you are trying to achieve …

Post your WP admin details in a private reply if you want us to have a look at your settings.

Thanks

Other question, if the admin of the site create the invoice from the admin panel, and the user pay it on front-end, that can cause this type of bug ?

It should not.

Only checking on the site that has the problem would work.
Let us know when we can have access to a site where we can investigate the problem if it keeps happening.
Thanks

Hi Shad
The renewal invoice should be generated around the time of the renewal, not in the beginning.
Is this happening for all your renewals?
Is PayPal paying you twice?
Can we check the settings of the item please. Please post your URL and WP admin details in a private reply and we will have a look.
Thanks

I have alerted a developer to have a closer look. Thanks
