If you need an older invoice, for account that you've already cancelled in the past, then first we recommend to check your email inbox (and spam box, as well), since we send you all the invoices directly to your email.
If you did not find the invoice you need, and you can't access it in the Agorapulse Manager, then drop us an email and we'll search the universe to find that document for you :-)
It would be awesome if you include a clue (name and/or email of your account, name of the page, etc.) so that we can find it easily. Thanks!
