Invoicing
An invoice that's already been issued is never modified or deleted. If there's an error or a return, another invoice is issued to correct it: the rectifying invoice.
Generally, you have up to four years to issue a correction; if the error harms the client, it's best to do it as soon as possible.
Lúcido blocks editing of invoices that have already been issued so that no information changes by accident, and guides you through creating the rectifying invoice linked to the original.
