Thanks for getting back here, @Aggrandise VA.
I've got a few troubleshooting steps to help you fix this so we can get you back in working order.
To start, let's first review the FRS VAT code and make sure that it is applied to sales. This way, we can ensure that the code will show on the VAT field when creating an invoice. To do so, please follow these steps:
- Go to the Taxes menu.
- Click Edit VAT and choose Edit Rates.
- Look for the FRS VAT code you set up and select Edit.
- From there, ensure that it has a Sales rate %. This indicates that the code is assigned to sales.
For more info about the process, please see this article: Create a new VAT code.
However, if everything is verified to be correct and the FRS VAT code still doesn't show up on the invoice, I highly recommend reaching out to our Customer Care team to further investigate the root cause of the issue. They use specific tools to pull up your account in a secure place to check your setup.
Also, I've noticed that the screenshot you've added was not uploaded successfully. To help you upload it, you can edit your previous response by clicking the 3 dots and choose Edit Reply. Once opened, click the Photo icon to insert the screenshot you want to attach.
