Why is the VAT amount saving incorrectly? It is correct when I save but when I preview the invoice to send it is wrong.

Let's try saving the invoice on an incognito window, bethvansyckle-gm.

 It is where we can confirm if the error is cause by a browser-related issue. I've added these keyboard keys to open one:

• Google Chrome: Ctrl + Shift + N
• Mozilla Firefox: Ctrl + Shift + P
• Microsoft Edge: Ctrl + Shift + P
• Safari: Command + Shift + N

If it works, we can go back to a regular browser and clear the cache. Once cache is piled up, it can be the reason for some unexpected browser issues. 

 We also have the option to switch to a different browser like Google Chrome, Mozilla Firefox, Safari, or Microsoft Edge as an alternative.

I've also added this guide for more information about VAT: Set up and edit VAT settings, VAT codes, and VAT rates.

Get in touch with me if ever you have other concerns about sending an invoice. Keep safe!
