Voiding vs deleting an invoice

Two ways to "remove" an invoice. They behave differently.

Void - Status flips to "void". Invoice stays visible for audit. - Source records (timesheets, expenses, milestones) get unlinked, so they become billable again. - Cannot be edited or re-sent. - Refused if any payment has been recorded — record a refund + issue a credit note instead.

Delete - Soft-deletes the invoice. Disappears from lists. - Source records also get unlinked. - Use sparingly — void preserves the audit trail better.

For a paid invoice you wish you'd never sent, the right path is: record a refund, issue a credit note for the full amount, then void.
