I have just registered as VAT vendor, and i have just added on the company profile on Quick Books , however it doesn't reflect on my estanite or quote and invoices,

I can help you set up your VAT rates and use them on forms, @Cardiway2011.

First, you must turn on this feature from your VAT menu. Here's how:

1. Go to the VAT menu and click on Set up VAT.
2. From the Setup VAT page, choose the Start of VAT period (the date that you became a VAT registered), Filing frequency, Reporting method, and your VAT Registration No.
3. Hit on Next.
4. Press on OK to save all the information.

When you now create invoices, quotes, and all other sales forms, you'll now have this VAT column.
