Good afternoon everybody,

We have started using Odoo not long ago, which means that we have transactions and invoices that were processed using another accounting system. I have to issue a partial refund, but I don't have the original invoice in my database. 

Can I still create a Credit Note and send it to the customer? Will this work as a Refund Invoice, where the customer will be refunded for the amount I owe him?

Thank you so much!
