Yes. Deleting a draft invoice makes it Inactive rather than erasing it, so you can bring it back at any time.
- Open Invoices.
- Set the Active/Inactive filter on the list to Inactive.
- Find the invoice you deleted.
- Use its Active/Inactive dropdown to set it back to Active.
What happens
- The invoice returns to your normal list with all its lines.
- It is still a Draft, so you can edit it or issue it.
Good to know Only drafts can be deleted. An issued invoice is never deleted, because its number and QR code are already final.
