Hi there, @AndrewBI.
I'd be happy to help you make the VAT add up on the subtotal. To do that, you may want to check the customization of your Purchase Order (P.O) Template and check if any changes make the VAT not calculating in the Subtotal.
Here's how to check the Purchase order template:
- Go to the Lists menu and select Templates.
- Look for the Purchase Order template that you're using and click it.
- Select the Additional Customization at the bottom.
- Check the contents of the template ang go to the Footer tab.
- Make any changes you preferred to the template to add the VAT amount.
- Save the changes.
Once done, make a test P.O and check if the VAT is already included. If not, I'd recommend contacting our Customer Care Team. They have the tools to perform screen share sessions and verify your account. Here's how to contact them:
- On your QuickBooks homepage, go to the Help menu.
- Choose QuickBooks Desktop Help.
- Tap the Contact us button.
I've added an article for your additional reference on managing your templates: Use and customise form templates.
I'll be here if you have other concerns. Tag my name in the comment section to let me know. Take care.
