No, once an invoice has been marked as paid, it cannot be directly updated with a different template. Here's how you can manage the situation if an update is necessary:
Changing Template Before Payment: If the invoice is still in draft or sent status, you can change the template. Go to the billing section, select the invoice, click “Edit”, change to the desired template on the line-item screen, and then save the invoice by either generating the invoice or sending the email, depending on the current status.
Updating a Paid Invoice:
Create a New Invoice: Generate a new invoice with the correct details by going to the billing section and selecting "Create New Invoice."
Delete the Previous Invoice: If necessary, delete the previously paid invoice. Note that deleting an invoice permanently removes it from the platform, so ensure that all necessary information is saved or noted elsewhere before deletion.
Mark the New Invoice as Paid: Once the new invoice is created, mark it as paid to reflect the updated transaction details.
Communicating Changes: Always communicate any invoice adjustments or deletions to your client to maintain transparency and ensure their records are updated.
This approach ensures that all financial transactions are accurately reflected and recorded while maintaining clear communication with your clients.
