Sera allows for the option to edit or void an invoice. The important distinction would be if you want to continue to work with the invoice in the future.
Editing the invoice
If you need to adjust the total of the invoice, or add/remove line items, you will want to edit the invoice. Locate the invoice, select the Invoice Actions button and select Edit Invoice. This will remove the Finalized label, and unlock the invoice to allow for editing.
Please see our article on Editing Invoices for more detail.
Voiding the invoice
If you no longer need the invoice and you would like to completely remove the financial liability of your customer to pay that invoice, you will want to void the invoice.
Note: All payments will have to be refunded from the invoice before it can be voided. Please use extreme caution when voiding as this action cannot be undone. If you void an invoice in error, it will have to be completely recreated.
To void an invoice, locate the invoice, select the Invoice Actions button and select Void Invoice. You will enter a note about the reason for voiding. This note will be saved in the 'All' notes of the customer's account.
